What are some other shows or movies you want me to watch and react to? Also if you have book recommendations for cool sci-fi/fantasy crossovers let me know! 👌
I thought it was weird that they could find metallic magnesium when it's so reactive that it should have reacted with the various other elements present already, especially water and oxygen. You don't find metallic magnesium naturally on Earth for this reason, it's produced via electrolysis or reduction with carbon.
I have one theory that might make it work. A magnesium asteroid impact (part of a super nova remnant) could have at one time broken the crust of the planet and created a caldera. In the presence of sulfur, the magnesium could be encased in magnesium sulfate, preventing galvanic corrosion. Once the metallic magnesium is exposed to air, a magnesium oxide pre-corrosiom layer would form, protecting the magnesium. This all hinges on how much magnesium is present, grouped together. It could never survive in a planetary formation. It would be oxidized before the dust ever gathered into pebbles.
@@lordmunch1 - That may be, but the various science errors throughout the first episode -- not all of which are even mentioned in this video -- were like nails on chalkboard to me. I couldn't take it anymore.
The odds of bumping into an Earth-like planet in the Goldilocks zone are a hell of a lot better than the odds of bumping into one outside of the Goldilocks zone...

This was fun! If you're gonna do more of these, I think it could be interesting to point out unusual details the movie/series gets _right_. In scifi there's a lot of odd stuff going on, and it's often not obvious when something is actually realistic, or at least an attempt was made to take real physics into account.
Ian M Banks - The Culture series. Unusually good and amazingly consistent for modern sci fi. Not to be confused with Ian Banks political novels. Same person, different genres. Netflix said they were going to film Consider Phlebas but then that seemed to fall into an alternative timeline.
I'd love to see you react to some of the other episodes in this series. A lot of the "woo" sci-fi gets explained, at least within the story, and there is a very wide mix of plausible and implausible story elements. It's hard to discuss without spoilers.
I'd vote for the Expanse (it's on Amazon Prime). I'd love to see a discussion of how "close" they got on the acceleration physics. (Also, their zero-g wirework is amazing!)
Big Peter Hamilton fan here. The "Reality Dysfunction" series is so epic and has so much speculative science, from uploaded consciousness to organic "voidships" with designed-in "affinities" for the pilot, demi-gods and so much more!
Yeah those are some fun books. My only gripe with the Expanse TV series is that it means Reality Dysfunction probably wont ever get made into a series as it would be viewed as a knockoff because they both have magic space zombies.
Definitely check out The Expanse! It's the first show I've seen that really gives you a vague spatial impression of just how vast even the Solar system is. And it's pretty low on SciFiy McGuffins, the only major ones are a hyper-efficient fusion thruster engine and some weird alien(?) microorganism.
...and the major fact that you can't have living spaces/factories/etc within astroids like that at all... The Expanse is great, don't get me wrong! But there are also quite a LOT of things scientifically hogwash and completely wrong with it though. Saying " _pretty low on SciFy McGuffins_ " is streching it....
@@CookieTube Well, why not? The asteroids are spinned artificially to create a gravity-like effect. I don't know. I would assume we don't really know how possible it actually is.
@@Kuhmuhnistische_Partei It has been calculated and shown that you can not spin such asteroids fast enough to create artificial gravity without spinning them completely apart, they will simply break up (If I'm not mistake there is even a paper about it). Moreover, the depicted kind of artificial gravity is not correct for 'small cities' like that. The concept of hollowing out big asteroids and creating artificial gravity by spinning them is not possible like that. But I suppose it is good enough for a show like this though, I've seen far worse. So, don't get me wrong, they get a whole lot correct (eg: the space battles are very correct, except for a few minor details), but not everything is scientifically accurate.... It is afterall still a TV-show where they need to cut corners here and there...
@@CookieTube The asteroids aren't at full Earth gravity, though, even if they're being spun. The belters, and Martians, find full Earth gravity almost unbearable don't forget
@@johnfairhurstReviews Doesn't matter. You'd need to spin them way too fast either way. Again, this is has been looked into already and shown to be one of the shows 'liberties' to reality. And even if you can keep it together, for a human (belter or not) it would be dead sickening inside because of the centrifugal(? or that other name for it, dunno) force between your head and feet or something, can't remember. But I do remember it is not as easy as shown in most shows. Again, there are very good video's/docu's about this (search something like "can you make artificial gravity by spinning"). This is something many many (if not all?) shows get wrong apparently, or at least don't show. You'd need a very large diameter (larger than depicted in most shows) for something like that to even remotely work and not making the people sick or be able to function 'normal'. Another MAJOR thing they get 'wrong'/or better said: took MAJOR liberties with, is the size and time it takes to travel in the solar system, even with the propulsion systems they use. On UA-cam there are quite a lot of video's about all this. Very interesting. And it actually makes you appreciate the show even more, because they DO get a whole lot correct though (especially how craft move in space. And even many aspects of the design and practical functioning of the ships is very good!).... It shows were they goofed up quite a bit (even non-sensical and completely wrong science stuff), were they took liberties (because, it is a TV-show afterall), were they kind of bend the rules a tiny little bit to make it work, and were they are very accurate in their science.
Dr. Becky, as what you've said on the video, life could also evolve in other elements. So is it possible for both silicon-based life and carbon-based life to coexist in the same planet? Or also perhaps on the liquid methane and ethane on Titan's rivers and lakes? And what other elements could life probably evolve from?
Silicon is the next best option to carbon. Silicon is ~100 times more abundant than carbon on earth, so the chance should be bigger but it didn't happen.
Have you done a video like this on 'The Expanse'? I love your videos btw. I hate that I'm not on the level that I would need to truly understand any kind of physics. I do appreciate how you explain it so well though.
I loved this show. It's fun seeing your perspective on it. I'm wondering about what you thought about how quickly that ice froze around the girl? To me that seemed unrealistic. In terms of what other sci-fi shows to react to, I'm sure you've already seen Firefly but Dark Matter is a more recent show that's somewhat similar. Though really any sci-fi show reactions would be great no matter which show it is.
So glad to know the host of my recently discovered channel is a sci-fi nerd as well..We all know science fiction inspires science fact. Way to go Becky, keep 'em coming..
Love the way that, when talking about the odds of finding a "goldilocks" planet, everybody somehow managed to avoid the the phrase, "..the odds are astronomical.." 😎
And a book worth checking out, if you can find it, is The Gameplayers of Zan" by M A Foster. loved this book, about an attempt to create a race of superhumans, which instead created a race of Other Humans. A really well written book, with attention to languages, and the life of the "other" human race.
Lol. My thoughts too. However, what actually are the odds? In my simplified view, the odds are planet(s) we know have life divided by planets we know well enough to say don't have life. Of course, it is not that simple, but there is a better way to find the actual odds?
My younger cousin introduced me to this show. I watched through it all and seriously enjoyed it. I feel like it wasn't SUPER heavy on the astrophysics side of things which is sorta what I hope to see when going into a space story (because I love a *lot* of realistic sci with my fi), but I enjoyed how outside-the-box the characters got with their problem solving when faced with incredibly unique situations. I watched it around the same time I was reading Apollo 11 which was a memoir by astronaut Jim Lovell, and that also showcased some incredible, real ingenuity that I loved. These two stories entirely reshaped the way I tackle problems while also inspiring me to start writing my own sci-fi novel. Lost In Space has a special place in my heart for that.
@Dr. Becky I'd love it so very, very much if you'd be willing to do an ENTIRE episode on Ringularities, particularly now that we believe Powehi is rotating at near the theoretical maximum speed, with an absurd quantity of retained angular momentum. Moreover, how fun would it be to have a discussion of just how that much angular momentum can be gathered into a black hole? Are singularities truly point-like? How does spatial dimension apply? What sorts of weird physics do we expect in ringularities that aren't seen in singularities? How does an infalling object interact with a ringularity compared to a singularity? How big would we expect a ringularity to be in terms of defineable physical dimensions (if such a concept even applies on the no return side of the event horizon). I see many, many physicists who will touch briefly on the ringularity, but I feel a potent, unending hunger for a really hearty rich, proper meal of theory. I feel like the discussion of the differences between a ringularity and a singularity will help us all understand the nature of black holes a bit better.
@Dr. Becky I just watched the video and went batty when you mentioned the Einstein Rosen bridge. I saw it coming when you started talking about it like 30 seconds before you brought it up. I was like is she going to mention it?
I started watching the first episode a year or so ago and gave up after 20 minutes because the sound mixing annoyed me. I couldn’t hear what the characters were saying over the music. Maybe I was just in a weird mood that day - everyone says it’s really good so maybe I should give it another chance
@@DrBecky The Expanse treats space travel with more realism than any other film or TV I've seen. It would be the most interesting one to spot mistakes in. Some of the accents are pretty thick though.
An easy comparison, when comparing the distance to the Centauri triplets, is the Oregon Trail - walking from St Louis to The Dalles in like 100 days. But at 10% light speed, it would be more like following Moses around in the desert.
When I was at school in the 60's we did some aluminium casting and used broken up old gear box casings as a source of aluminium, on one ocasion it turned out that the gearbox case was magnesium, as we were using an open crucible on a coal fired forge it caught alight burnt a hole in the ceiling of the metal workshop before we manage to put the fire out with sand. I have always thaught that to get a wormhole in space you would need a black hole at each end to get enough curvature and therfore a wormhole would be useless for space travel as anything entering it would be ripped apart by the black hole.
To take you out of your astrophysics comfort zone and thrust you into VR I would recommend Tad Williams "OTHERLAND" series. It's not about outer-space but about inner-space. Or for a movie, how about "The Martian".
In Robert Heinlein's seminal novel _Stranger in a Strange Land,_ he mentions in reference to the planets in our solar system; *"All of them, as is always the case, were infected with that oddity of distorted entropy called life"* which is an interesting way of putting it. This was back in the 60's, and there was a fairly sizable belief then that life was incredibly common in the universe. I think we are coming to the conclusion now, after 50+ years of investigation, that the opposite is probably true. Life may not be unique on this big blue marble, but it's likely to be very rare indeed. Unfortunately this makes for uninteresting science fiction. It's tough to have conflict between the unliving uncaring universe and a single tiny species from an out-of-the-way planet orbiting an inconspicuous little yellow star. This is not to say that there is _no_ other life in the vastness of our universe, but simply that it's so rare that there's little chance of our ever encountering it. But remember it's also possible that life evolving on this fragile little sphere is unique. We may be alone in the uncaring universe, and that's a chilling thought.
It could equally be true that life is commonplace, but life that resides on planetary surfaces (making it easy to detect) is extremely rare. After all, most of Earth's biomass is underground.
You needed to have watched all the seasons. The Near Earth Object was actually an alien starship with a warp drive that we stole. The evil robot was trying to get it back
A book and a film that both easily accessible for being relatively short read - and still a terrifying Hard sci-fi - is "The Andromeda Strain" by Michael Crichton. Sure, I've read lots of Iain M Banks, Ken McLeod, Neal Stevenson - that's just the authors in this genre I collect anything by (incl. Umberto Eco). "The Andromeda Strain" movie freaks me out in a totally novel and groundbreaking way. So I read the book and there's only a subtle difference, except right at the end; where the movie shows a computer simulation ("err 522" I think…), the book is a short epilogue less than one page long and that terror is totally revived - one of the most astonishing literary experiences of my life from a piece of sci-fi pulp fiction from a guy who specialised biology and medicine.
OK. Very late with this. But I only recently found your channel. I thought Lost In Space had too many points where it tested my ability to suspend reality. One thing that irritates me no end in SciFi films (even ones I like, such as Trekkie ones. Contact. Arrival.) is that a robotic being, no matter if it has an organic component or not, always seems to be able to use soooooo much power. Strength. Heat. Lasers. Other powers as yet unknown. Where the heck is all that energy coming from??!! Some 24 volt Li battery tucked in a leg?? Anyway. Please check out "The Dish". You'll love it.
Extraction hood ? When I was at school they just passed out the magnesium ribbon ,tongs and Bunsen burner to light it and we all set it alight in class . Pretty sure the Windows weren't even opened .
Lol, i remember when I watched this what i was thinking with that magnesium thing was was that magnesium is pretty reactive and it would probably only be found in a salt/oxide ore not in it's raw metallic form. this show is interesting in that in the plot they basically solve a bunch of high-school physics type problems in order to survive they skip a lot of steps that would have to happen in the real world.
The pairs are like. Mercury Venus. Earth Mars. Jupiter sun. Uranus Neptune. Boundary leftover of Jupiter Pluto and asteroid belts. They usually exchange place ones on a blue moon.
As I understand it a "wormhole" requires 2 entangled black holes spinning at insanely high speeds for a corridor to form. Still going through Leonard Susskind's lectures on EPR.
A more sciency than ficion-y suggestion: HBO’s »Chernobyl« miniseries. Only 5 parts, but golly, did they nail that. Absolutely chilling, and the accuracy of the events depicted is really something to behold. That catastrophe could have been even worse in many respects. Europe’s gotten off comparably easily.
dipi But that’s not scifi at all. The entire series can be explained with today’s physics, so any holes in it is a mistake. Scifi is about looking into the unknown. To pick scientific questions which are yet to be answered, and fill these holes with assumptions and ideas instead of proven theories. A good scifi uses hypotheses which doesn’t contradict with our current knowledge, so it is actually possible to happen in the future. A less good scifi picks one or two theories and asks “what if”. A bad scifi contradicts with science all the way. Chernobyl would need to contradict science all the way, if it wouldn’t use hard and proven physics.
Magnesium exists naturally in minerals in the 2+ oxidation state (e.g. in magnesite and dolomite), not as a pure metal. You would have to find a way to refine the magnesium from the raw ore in order to use it the way they did in the episode. However, I think the heat wouldn't be a huge problem, since she is completely surrounded in a block of ice. Magnesium flames reach a very high temperature, but they don't actually produce all that much thermal energy by comparison to the thermal mass of tons of ice. The magnesium metal is reacting with liquid water to form solid MgO and hydrogen gas. The enthalpy of reaction is only about -315.8 kJ/mol, since it takes a lot of energy to break the OH bonds in the water. Even if you find 10 kg of magnesium metal and burn all of it, that's only about 410 mol or 130 MJ. That sounds like a lot, but it's only enough to melt 390 kg of ice at the melting point. If the ice started out at -50 C, it could only melt about 240 kg, or about a quarter of a cubic meter. It's not surprising it didn't make much of a dent, especially when you consider the amount of energy lost to vaporizing water and to the air.
Carl Sagan called up Kip Thorne when writing the book Contact and said he wanted to cross the universe by falling into a black hole. Kip suggested a worm hole instead.
Dr. Becky, there's 10 seasons of Stargate SG-1 waiting for you somewhere. Much of it a little more rooted in science... Like referring to the wormhole that the stargates generate as an Einstein-Rosen Bridge.
SInce as I stated below Netflix Lost in Space is little more than "Swiss Family Robinson", kid's show science fantasy - I enjoyed it despite it's lack of real science, it's just a family adventure using sci-fi genre and little more. I look forward to next season. I'd much rather see Dr. Becky's take on The Expanse for something cleaving a little closer to reality. You can read the books or watch the 3 seasons shown on Syfy channel, though it's cancelled now, so would require watching the DVDs. As an aside, I'm a small tabletop roleplaying game author, cartographer, illustrator and publisher creating science fantasy content for the Starfinder Roleplaying Game. You would cringe at some of my sci-fi-esque unscientific aspects of my work - but then Starfinder is magic and megacorps, science if mostly out the window, though I try to bring some reality to shore up the fiction.
I also would highly recommend you look at the Expanse, its set in a not too distant future where the is Earth, a Independent Mars Colony and Belters mining and living their entire lives around the asteroids and gas giant moons. Ooopps! maybe i should have looked at the thread above.
Dr Becky: I noticed the NASA tee. Two questions: 1) do you prefer the traditional NASA ot the 'worm' type-style. 2) Is NASA respected world-wide for it's science (and budget)?
Landed man on the Moon, sent out the Voyagers, launched hubble and serviced it with the space shuttle. What more do you want them to do to be respected?
@@alanjenkins1508and Dune is an allegory for different nations plundering the resources of the middle east...sometimes it is more fun to just take the adventure of a book at face value rather than reading into it...Ha!
I'm sure everybody has already suggested "The Expanse" but also "The Expanse." I've been meaning to read Ian M. Banks' "Culture" series, does anybody have any suggestions before I dive into that one?
Also the heat capacity and heat of fusion of water are really high, there's no way they thought that tiny chunk of magnesium would release enough energy to melt several tons of ice
And I thought the problem with wormholes is that whatever mass travels through it causes an equal and opposite mass to travel the other way and they both annihilate each other in the centre.
Love the shirt btw. I am a retired electrical engineer who very much enjoys your videos. I am also a great fan of WHATDAMATH. You both have a good communications style. Looking forward to more videos. An interesting older movie soylant green is well worth the time to watch. Would you consider doing a fiction and non-fiction book list? Also like many others here I love the Expanse, made in Canada (like me) where most great science fiction seem to be made (IMO).
The alien robot could be heating the ice with magnetic induction. I don't know how well it would work on ice, but it can bring metals to white hot temperatures in seconds.
Great video ! Thanks Becky for the video 🙂 What did surprise me in this episod is how long it takes to freeze water in this planet..I was once fishing in a lake in Canada with -37C and heavy freezing wind. The outer surface of the holes froze in 15 minutes or so ! Is it the salinity of water ? For me the temperature ( -60C if I remember ? ) doesn't explain this speed !
Could you explain why we dont see the effects of time dilation in those movies about people crossing the galaxy at light speed? I mean, in some movies they cross thousands of light years then back to home for dinner😂
There's a great book trilogy called Remembrance of Earths Past by Liu Cixin that has some of the best/most realistic sci-fi writing that I've read in a while.
If you look at where we are in cybernetics and AI today as to where we were in basic computing in the 1980's, in 40 years time reality may have caught up to fiction in terms of automation.
You missed the little detail of what fuel they use for their spaceships. Maybe it is in another episode. They use methanol, and in quantities that fit in a truck. I guess they did not know about dilithium crystals? Or antimatter? Or maybe they should have used good old plutonium. At least, if they had invented a fuel source, they could have assigned it an insane energy density instead of using something that we all know does not work.
What are some other shows or movies you want me to watch and react to? Also if you have book recommendations for cool sci-fi/fantasy crossovers let me know! 👌

@Dr. Becky I'd love it so very, very much if you'd be willing to do an ENTIRE episode on Ringularities, particularly now that we believe Powehi is rotating at near the theoretical maximum speed, with an absurd quantity of retained angular momentum. Moreover, how fun would it be to have a discussion of just how that much angular momentum can be gathered into a black hole?
Are singularities truly point-like? How does spatial dimension apply? What sorts of weird physics do we expect in ringularities that aren't seen in singularities? How does an infalling object interact with a ringularity compared to a singularity? How big would we expect a ringularity to be in terms of defineable physical dimensions (if such a concept even applies on the no return side of the event horizon).
I see many, many physicists who will touch briefly on the ringularity, but I feel a potent, unending hunger for a really hearty rich, proper meal of theory. I feel like the discussion of the differences between a ringularity and a singularity will help us all understand the nature of black holes a bit better.
I managed 3 episodes in before I gave up. The most convincing dialogue is from the big metal guy who says "Danger Will Robinson"
Best acting too.
@@ptonpc Absolutely. It seems being metal is not the only reason he is the least wooden.
@Dr. Becky I just watched the video and went batty when you mentioned the Einstein Rosen bridge. I saw it coming when you started talking about it like 30 seconds before you brought it up. I was like is she going to mention it?
This is the only way I would ever even come close to watching these sorts of movies. Cheers Becky!
I think you could drive metal spikes into the ice around the girl and use induction heating to melt it.
Also, what are your thoughts on The Expanse?
I started watching the first episode a year or so ago and gave up after 20 minutes because the sound mixing annoyed me. I couldn’t hear what the characters were saying over the music. Maybe I was just in a weird mood that day - everyone says it’s really good so maybe I should give it another chance
@@DrBecky The Expanse treats space travel with more realism than any other film or TV I've seen. It would be the most interesting one to spot mistakes in.
Some of the accents are pretty thick though.
@@DrBecky Dang you science people are so picky.
An easy comparison, when comparing the distance to the Centauri triplets, is the Oregon Trail - walking from St Louis to The Dalles in like 100 days. But at 10% light speed, it would be more like following Moses around in the desert.
Wine slave? where did you buy it? ;-)
One other note about magnesium burning: it gives off a TON of UV, so sunburn is a big issue, regardless of the intensity.
When I was at school in the 60's we did some aluminium casting and used broken up old gear box casings as a source of aluminium, on one ocasion it turned out that the gearbox case was magnesium, as we were using an open crucible on a coal fired forge it caught alight burnt a hole in the ceiling of the metal workshop before we manage to put the fire out with sand. I have always thaught that to get a wormhole in space you would need a black hole at each end to get enough curvature and therfore a wormhole would be useless for space travel as anything entering it would be ripped apart by the black hole.
"Hehehe wine time" lololol I actually snorted
To take you out of your astrophysics comfort zone and thrust you into VR I would recommend Tad Williams "OTHERLAND" series. It's not about outer-space but about inner-space. Or for a movie, how about "The Martian".
Dr. Becky you're the best! Your videos are constantly on in my house. I'd really love to see you watch The Expanse.
"Crazy Alien Space Heater Guy", lol...
In Robert Heinlein's seminal novel _Stranger in a Strange Land,_ he mentions in reference to the planets in our solar system; *"All of them, as is always the case, were infected with that oddity of distorted entropy called life"* which is an interesting way of putting it. This was back in the 60's, and there was a fairly sizable belief then that life was incredibly common in the universe. I think we are coming to the conclusion now, after 50+ years of investigation, that the opposite is probably true. Life may not be unique on this big blue marble, but it's likely to be very rare indeed. Unfortunately this makes for uninteresting science fiction. It's tough to have conflict between the unliving uncaring universe and a single tiny species from an out-of-the-way planet orbiting an inconspicuous little yellow star.
This is not to say that there is _no_ other life in the vastness of our universe, but simply that it's so rare that there's little chance of our ever encountering it. But remember it's also possible that life evolving on this fragile little sphere is unique. We may be alone in the uncaring universe, and that's a chilling thought.
It could equally be true that life is commonplace, but life that resides on planetary surfaces (making it easy to detect) is extremely rare. After all, most of Earth's biomass is underground.
You needed to have watched all the seasons. The Near Earth Object was actually an alien starship with a warp drive that we stole. The evil robot was trying to get it back
A book and a film that both easily accessible for being relatively short read - and still a terrifying Hard sci-fi - is "The Andromeda Strain" by Michael Crichton.
Sure, I've read lots of Iain M Banks, Ken McLeod, Neal Stevenson - that's just the authors in this genre I collect anything by (incl. Umberto Eco). "The Andromeda Strain" movie freaks me out in a totally novel and groundbreaking way. So I read the book and there's only a subtle difference, except right at the end; where the movie shows a computer simulation ("err 522" I think…), the book is a short epilogue less than one page long and that terror is totally revived - one of the most astonishing literary experiences of my life from a piece of sci-fi pulp fiction from a guy who specialised biology and medicine.
love that movie
OK. Very late with this. But I only recently found your channel. I thought Lost In Space had too many points where it tested my ability to suspend reality. One thing that irritates me no end in SciFi films (even ones I like, such as Trekkie ones. Contact. Arrival.) is that a robotic being, no matter if it has an organic component or not, always seems to be able to use soooooo much power. Strength. Heat. Lasers. Other powers as yet unknown. Where the heck is all that energy coming from??!! Some 24 volt Li battery tucked in a leg??
Anyway. Please check out "The Dish". You'll love it.
The ice melting with hands can be done by induction or maybe even just infrared radiation.
Extraction hood ? When I was at school they just passed out the magnesium ribbon ,tongs and Bunsen burner to light it and we all set it alight in class . Pretty sure the Windows weren't even opened .
Lol, i remember when I watched this what i was thinking with that magnesium thing was was that magnesium is pretty reactive and it would probably only be found in a salt/oxide ore not in it's raw metallic form.
this show is interesting in that in the plot they basically solve a bunch of high-school physics type problems in order to survive they skip a lot of steps that would have to happen in the real world.
7:00 I feel like you were speaking to me directly here Dr. Becky XD
The pairs are like. Mercury Venus. Earth Mars. Jupiter sun. Uranus Neptune. Boundary leftover of Jupiter Pluto and asteroid belts. They usually exchange place ones on a blue moon.
I always wondered where they kept the fuel or energy source to make th e Jupiter 2 fly for so long!
As I understand it a "wormhole" requires 2 entangled black holes spinning at insanely high speeds for a corridor to form. Still going through Leonard Susskind's lectures on EPR.
A more sciency than ficion-y suggestion: HBO’s »Chernobyl« miniseries. Only 5 parts, but golly, did they nail that.
Absolutely chilling, and the accuracy of the events depicted is really something to behold.
That catastrophe could have been even worse in many respects. Europe’s gotten off comparably easily.
dipi But that’s not scifi at all. The entire series can be explained with today’s physics, so any holes in it is a mistake.
Scifi is about looking into the unknown. To pick scientific questions which are yet to be answered, and fill these holes with assumptions and ideas instead of proven theories.
A good scifi uses hypotheses which doesn’t contradict with our current knowledge, so it is actually possible to happen in the future. A less good scifi picks one or two theories and asks “what if”. A bad scifi contradicts with science all the way.
Chernobyl would need to contradict science all the way, if it wouldn’t use hard and proven physics.
If you are into time travel and are wondering if Novikov got his theory right then you can watch the scifi series "Continuum" on amazon prime.
I love the NASA T-shirt. Nice touch!
Watch the series Farscape, aired 1999-2003 on the syfy channel.
If you like time travel stories you may like "Millenium" by John Varley. Jack Finney is another one to check out.
No , that's what would be cool is being a fly on the wall listening to all this during a movie like this with you . Excellent call Dr. Becky
Lots of fun! Thanks so much.
Magnesium exists naturally in minerals in the 2+ oxidation state (e.g. in magnesite and dolomite), not as a pure metal. You would have to find a way to refine the magnesium from the raw ore in order to use it the way they did in the episode. However, I think the heat wouldn't be a huge problem, since she is completely surrounded in a block of ice. Magnesium flames reach a very high temperature, but they don't actually produce all that much thermal energy by comparison to the thermal mass of tons of ice. The magnesium metal is reacting with liquid water to form solid MgO and hydrogen gas. The enthalpy of reaction is only about -315.8 kJ/mol, since it takes a lot of energy to break the OH bonds in the water. Even if you find 10 kg of magnesium metal and burn all of it, that's only about 410 mol or 130 MJ. That sounds like a lot, but it's only enough to melt 390 kg of ice at the melting point. If the ice started out at -50 C, it could only melt about 240 kg, or about a quarter of a cubic meter. It's not surprising it didn't make much of a dent, especially when you consider the amount of energy lost to vaporizing water and to the air.
Dr. Becky, can you recommend some "hard" sci-fi books? Something that's mostly plausible, unlike Warp drive and such tv tropes?
Carl Sagan called up Kip Thorne when writing the book Contact and said he wanted to cross the universe by falling into a black hole. Kip suggested a worm hole instead.
Instantly subbed... best looking Doc EVER... interesting Topic, sympathic and clear Explains. 👍
I would love it if you finished the whole Lost in Space season. Season two is coming so it'd be nice if you finished before then, Thanks 😋
You need to watch the original series. Bill Mumy, who played Lanier in Babylon 5 plays Will Robinson.
Dr. Becky, there's 10 seasons of Stargate SG-1 waiting for you somewhere. Much of it a little more rooted in science... Like referring to the wormhole that the stargates generate as an Einstein-Rosen Bridge.
Loved the series. Hope they make season 2
google says yes
SInce as I stated below Netflix Lost in Space is little more than "Swiss Family Robinson", kid's show science fantasy - I enjoyed it despite it's lack of real science, it's just a family adventure using sci-fi genre and little more. I look forward to next season. I'd much rather see Dr. Becky's take on The Expanse for something cleaving a little closer to reality. You can read the books or watch the 3 seasons shown on Syfy channel, though it's cancelled now, so would require watching the DVDs.
As an aside, I'm a small tabletop roleplaying game author, cartographer, illustrator and publisher creating science fantasy content for the Starfinder Roleplaying Game. You would cringe at some of my sci-fi-esque unscientific aspects of my work - but then Starfinder is magic and megacorps, science if mostly out the window, though I try to bring some reality to shore up the fiction.
I also would highly recommend you look at the Expanse, its set in a not too distant future where the is Earth, a Independent Mars Colony and Belters mining and living their entire lives around the asteroids and gas giant moons. Ooopps! maybe i should have looked at the thread above.
why can we not see anything in the centre of the black hole?
So are you going to do episode reviews? And if not, how did you enjoy the series? I liked it despite all the holes. Parker Posey was fantastic.
Dr Becky: I noticed the NASA tee. Two questions: 1) do you prefer the traditional NASA ot the 'worm' type-style. 2) Is NASA respected world-wide for it's science (and budget)?
Landed man on the Moon, sent out the Voyagers, launched hubble and serviced it with the space shuttle. What more do you want them to do to be respected?
Can you get "The Orville" in the UK? It's both really funny and true to the spirit of the original Star Trek.
Yes, it’s on Amazon Prime here too.
The Mote in God's Eye. My latest sci-fi read. About humanity's first contact...decent read.
The aliens are an allegory for mankind's future on Earth.
@@alanjenkins1508and Dune is an allegory for different nations plundering the resources of the middle east...sometimes it is more fun to just take the adventure of a book at face value rather than reading into it...Ha!
Why do news stories in movies almost always start as soon as they turn on the TV?
I'm sure everybody has already suggested "The Expanse" but also "The Expanse."
I've been meaning to read Ian M. Banks' "Culture" series, does anybody have any suggestions before I dive into that one?
Player of Games was my favourite
Really enjoy every episode of your VBlog, What about the Movie Interstellar?
Also the heat capacity and heat of fusion of water are really high, there's no way they thought that tiny chunk of magnesium would release enough energy to melt several tons of ice
Read Accelerando book and react to it. chapter by chapter, because they are very different :)
I tried to watch the new LiS, but I didn't even get 20 minutes in. Turned it off.
Stick with it, as it’s actually good.
@@kadourimdou43 - - After seeing that clip of the robot, I have even less interest than before.
@@thinkbolt Fair-enough.
Billy Munny, the original Will Robinson made a Cameo in this episode.
Awsome video and Topic. Please review The Expance, The Orville and Startrek Next Generation
Yeah, the Expanse would be a good one for you to review regarding hard sci-fi.
Please review The Wandering Earth, it's hilarious! Also on Netflix.
Thank you Dr. Becky.
Love the Simply Nailogical reference. beynnnn!
YES DANIELLE! 🙌 I said it in the vain hope at least one person would get the reference
Let me suggest ian m banks (anything by him) or alistair reynolds if you like scifi. :)
Thanks for the recommendation - I’ll check it out!
And I thought the problem with wormholes is that whatever mass travels through it causes an equal and opposite mass to travel the other way and they both annihilate each other in the centre.
Love the shirt btw. I am a retired electrical engineer who very much enjoys your videos. I am also a great fan of WHATDAMATH. You both have a good communications style. Looking forward to more videos. An interesting older movie soylant green is well worth the time to watch. Would you consider doing a fiction and non-fiction book list? Also like many others here I love the Expanse, made in Canada (like me) where most great science fiction seem to be made (IMO).
The alien robot could be heating the ice with magnetic induction. I don't know how well it would work on ice, but it can bring metals to white hot temperatures in seconds.
I'd love to see you react to Stargate SG-1 sometime...
Dr Becky: I'm going to turn off the analytical part of my brain, and just enjoy it.
Also Dr Becky: ANALYZE ALL THE THINGS!!
Great video ! Thanks Becky for the video 🙂 What did surprise me in this episod is how long it takes to freeze water in this planet..I was once fishing in a lake in Canada with -37C and heavy freezing wind. The outer surface of the holes froze in 15 minutes or so !
Is it the salinity of water ? For me the temperature ( -60C if I remember ? ) doesn't explain this speed !
Look at the bar above the lady at 2:20. "HEIMPLANET" not 100% accurate but like home planet in German (Heimatplanet).
I reckon it would be accurate in Norwegian, though 🙂
I looked it up, it's an actual brand. So just advertising.
Could you explain why we dont see the effects of time dilation in those movies about people crossing the galaxy at light speed? I mean, in some movies they cross thousands of light years then back to home for dinner😂
There's a great book trilogy called Remembrance of Earths Past by Liu Cixin that has some of the best/most realistic sci-fi writing that I've read in a while.
Thanks for the book recommendation! I’ll check it out 👍
Oooh, a drink slave.
I congratulate you on your find... ;-)
lol yess
If you look at where we are in cybernetics and AI today as to where we were in basic computing in the 1980's, in 40 years time reality may have caught up to fiction in terms of automation.
You missed the little detail of what fuel they use for their spaceships. Maybe it is in another episode. They use methanol, and in quantities that fit in a truck. I guess they did not know about dilithium crystals? Or antimatter? Or maybe they should have used good old plutonium. At least, if they had invented a fuel source, they could have assigned it an insane energy density instead of using something that we all know does not work.
