8:21 “…this rocket hasn’t been launched yet…so…”
A big grain of salt that should also be applied to StarShip and Super Heavy. All too often commentators go on breathlessly about StarShip like all of its aspirational performance was already a given. An enormous number of chicks have been counted long before anything has hatched.
Absolutely, they're all suspect until they actually fly... twice.
Hale Bopp was amazing. One of the few things that got me into astronomy
I never even got to see Hale Bopp from really dark skies but I still have a memory of seeing it as a kid from our house and being amazed how bright it was.
Good to hear you're making enough off of Patreon to remove UA-cam ads. This channel for awhile has been a major source of space news for me and I'm glad to see its doing well.
Dope discovery, kids. That's great.
Hi Fraser, how feasible is it for private companies to have their own telescopes? How much do they need charge for telescope time to recover the costs?
Very excited for this bright comet! Fingers are crossed!
"Watch 2 Stars Impact Together" has been added to the Bucket List. :D
Bright comets are very nice. You just don't want them to be *too* bright, as dinosaurs can testify.
Thanks. Now I know the weather will be cloudy in October of 2024.
Thanks for the news, Fraser!
I love the smoked tint, so sleek!
And that powerboard looks so sick. May just be one of the most favorite builds I've ever seen, drool worthy.
Boosting the Hubble telescope is really cool. I love the JWST. But Hubble was the game changer.
Nice to see they're putting up another. Hubble too was originally a spy satellite modified for NASA iirc.
Heck yeah! JWST = Amazing! Hubble = OG helped kickstart this cool stuff and might be aging, but just like older folks, provides a different perspective you simply cannot get anywhere else... Let them work together and grab some popcorn 🍿 because you are about to have your mind blown into oblivion, reassembled and then do it again! ❤️🌎👽
Hey Fraser! Thanks to you I discovered the "Revelation Space" series and I am stunned by the storytelling, characters and creativity these books bring. Now, I have always had a bad hand in choosing Sci-Fi literature but you seem to know the really good stuff! Could you recommend some books in your Q&A sometime? Thanks in advance.
Hi Fraser, I have a question: since the SLS boosters are basically the same as in the 70s, how come there was so much ground damage? Was it like that in the 70s as well?
These are gold to come back and reabsorb few days/week later.
Degradation of epipen strikes me as odd that it happened so quickly. Maybe could be stabilized with antioxidant like ascorbate
Simply the best space news UA-cam channel.
Thanks!
I vote for the 🇨🇦 Kids. Poisonous epi pen is actually a big deal if you need one.
Thanks for all the news, Fraser! 😊
About the Hubble, I hope they boost it or capture it and bring it back. In the words of Dr Jones (Indiana Jones), it belongs in a museum!
Anyway, stay safe there with your family! 🖖😊
10:50 What bathroom? That 2 meter sphere is pretty typical of what I have seen.
Keep up the good work.
Very good program. Every one I watch as something new.
The link for the bright comet is the same with juno's io flyby
I Love your show and your personality so much... wonderful high sparkling quality presentation so grateful to get to watch and enjoy! Just wonderful content thank you....🤩
Wow, thank you!
Q&A what would happen if you had 2 objects one going 50% the speed of light and another going 51%the speed of light each object is going exactly on a line apart from each other would it immediately red shift or would something else happen assuming you are on one of the objects
"Would it immediatly redshift"
Edit out the "it" and just use the name of whatever you are talking about. Your question does not make sense, he will not be able to answer.
Thanks 👍
So long as The Universe doesn't deliver that comet directly to our doorstep. :D
I kind of wish they would give Hubble a hall effect tug so we can get it well up the gravity well
For the Epi-pen, did they keep it under pressure and at safe storage temperatures?
Good point I don’t know if that would have an affect on it but it could
Unlikely. He said they're planning to repeat the test with shielding.
Is strapping 2 more boosters to a Falcon heavy rocket with a larger faring a viable option until Starship is ready?
Question? What is the theoretical size of a planet, I've heard that planets will start to shrink if they get to massive. So what the limit in size before they turn into a star?
Is the distinction between planets and dwarf planets also done with exoplanets?
❓Could there be ways to get a signal through the superheated plasma upon a spacecraft’s atmospheric reentry?
A simple metal container or even a faraday cage should be adequate shielding to preserve the epinephrine and prevent it being decomposed into benzoic acid by cosmic rays…
Hale-Bopp was an awesome comet. Hyakutake was pretty good, too.
Now that's what a comet is supposed to look like!
Hi Fraser, can you help me understand the oberth effect? It seems backwards to me, when the spacecraft is at periapsis the velocity is greatest, therefore a change velocity will be relatively small compared to the total velocity so it seems that this should be the least efficient way to use fuel. What am I missing?
Did you see my recent interview. ua-cam.com/video/PxYecl2QvT0/v-deo.html
We talked about exactly that. Orbits are ellipses, so you get a multiplying effect when you burn at the closest point.
So VERY cool that they've named the new telescope after Nancy Grace Roman! One of my heroes! Hurray!!
As opposed to everything moving away from each other and the space in between things expanding could we all just be shrinking
I'm not gonna hold my breath for this comet... I remember hale bopp being amazing, and Halley being disappointing.. I tracked ISON from Jupiter to here thinking that was going to be the Millenium Comet... o more getting excited 😄
That's the right response.
@@frasercain You put the wrong link for the comet article. It leads to Io article instead.😊
I'm no scientist but I have been wondering if dark matter and anti-matter should interact in the same way as dark matter and regular matter. There are so many mysteries tied to both.
Jeeez, and I thought my Scania V8 had a big fuel tank.
What would the Earth's weather be like if there were no plants, but you still had all this water? And would that difference be detectable in exoplanets?
Toxicity of benzoic acid may be a bit overstated. It's a pretty common preservative. There's something like half a gram in a liter of mountain dew
Crazy to think that those distant colliding stars probably have planetary systems that could support life...
10:56 how do they come back to Earth?
That is mind blowing that epinephrine mutates so readily under the duress of cosmic radiation.
Hey Fraser, I’ve been wondering lately, what would it take for aliens on titan, or whatever planet it is, that is an icy world, and we think that it’s has an ocean underneath the ice. I can’t remember the name right now, and I don’t wanna go look, to escape from their planet, like us? I’m imagining in this scenario that there are squid like people or something, I am wondering what it would take for them to get through the ice, and then be able to escape their gravity well? Do you think there’s anything on the planet that they could use for energy to actually do that, from underwater?
Question, why did the moon ring like a bell when nasa smashed something into it? Do you think the hollow moon theory has any truth to it?
It was just an unfortunate turn of phrase, just like "black hole" leads us to think there's something "on the other side" of the "hole". Had NASA said the moon "resonated in an unexpected manner" then the hollow moon theory would likely not exist.
Awesome video, as always. In one of your previous videos, you had said something about a flux-tube or whatever of electrical current that connected the magnetic poles of Jupiter and Io. Assuming that there was some way that we could actually tap into that power and use some or all of that electricity, would it do anything to Jupiter or Io? Like, would it mess with their magnetic fields or alter Io's orbit?
The energy stolen from the system that you are referring to is taken from the dynamos that create the magnetic field. It wouldn't change orbits. Now if you stole momentum from a body in the form of a slingshot of a craft, this does change the orbit.
@@robertnewhart3547 That does make sense, but the part that keeps popping up in my head, is that changing electromagnetic fields induce or change currents in the conductors that carry/generate them. Like, if you had a circuit that was a big loop of wire which had two inductors in it on opposite sides, and you messed with the magnetic fields of those inductors, it would change the magnetic fields/currents in the other inductor. (I get that a planet/moon EM field is a lot more complicated, bu still.) If you were drawing enough electromagnetic energy from a dynamo the size of a moon (or bigger) would it change or modify the movement of said dynamo?
You would swear that with all the testing prior to a manned moon launches that we had NEVER been to the moon before, even once! ROFL
Hey Fraser. Could a human survive the g-forces of landing on a Falcon rocket? Do you think this will ever happen?
Besides it's ethical qualities, Space-X's "give and take" approach seems to be a very good model for preventing political tensions among space going nations, impacting space flight and science. Especially since Russia's pull out of ISS showed the first crack! If it was possible to have an Apollo Sojus docking in the cold war we should be able to achieve good working relationships and from time to time cooperations. Those won't stop the militarisation of space, but that makes opportunities for talking to one another all the more important!
14:20 Could SpaceX launch upgrade hardware for Hubble and someone to install it before boosting the orbit???
Maybe normal mater big bang was happened before the dark big bang that's why the oldest galaxies are very large in size
saturn v was 10 metres wide and N1 17 metres a the base(not sure about tanks which were spherical
ten times size of Moon is 5 degrees field of view. Moon is .5 degree or 30 minutes of arc. Mars overhead right now is a magnitude of 0.5, so pretty bright. In Taurus and looks like the Taurus alpha star Aldebaran.
As for the starlink problems could it one day be feasible to creat a “halo” like ring around Earth for satellites and space stations. Also it would be perfectly set to harvest electricity from the earth’s magnetic field for its own use and more power could be sent back to ground stations via radio/microwave transmitters.
I would prefer a heat engine to power this. There quite a diferencial of heat at high atmosphere levels. This along with both wind and solar(both are better up there) will generate enough power to both keep the ring charged and able to radiate power down.
@@fanOmry at the altitude I’m thinking it’d need to be, in some kinda equilibrium of orbit so it stays put with minimal adjustments, and won’t crash. There shouldn’t be wind, unless your meaning solar winds? But the heat differential yes for sure.
Also NASA did a test of a simple wire copper I think, for seeing power readings from it and it was way more then they thought. So a single loop around earth would be, a lot, but yes adding more options would be better, redundancy, plus more for ion thrusters to maintain stabile orbit and for ships other remote objects and back to earth. Plus it’d have to be an amazing antenna and telescope possibly, if used as an array.
@@mattduncil
I was thinking of tethered rings, they can be as low as 10-20 K in the air, at those hights, you can actually still have wind both fast and thick enough to carry power
@@fanOmry ok, can you explain or share a link to a video on that. Thanks
To save energy and make it possible to have more payload, I would change the technique to send material into space. Anyway, there are so much junk out there so ...
the 90s spoiled me for comets, but having a 400 yr drought for visible supernovas... thats the sky event ill greedily say the universe owes me... i mean us... US!! :)
Dark Bang!
That student thing was amazing . Nasa would be in right trouble in the future with civilian space flight wouldnt they? Lucky these students worked that out at a SUPER budget cost.
Hey Fraser thanks as usual. But c’mon. Ballon ride? First question from ALL friends will be “what was it like being weightless?” Long boring explanation follows. People quietly departing to get a drink. Yeah thanks but I’m all in for ORBIT not just a height ride!
It should be noted that Roman's Wide Field Instrument will have a 300 megapixel focal plane sensor, compared to 16 Mpx in Hubble's Wide Field Channel on Advanced Camera for Surveys. Wide field of view is of little use without extremely high resolution sensor.
BTW, the planned Chinese Xuntian survey telescope designed to be able to dock with their space station for maintenance and upgrades will have a bit smaller primary mirror but even wider field of view, and _2.5 gigapixel_ sensor.
30 years of optics and hardware improvements over Hubble. 😀
@@frasercain Less optics than electronics - 30 years ago Hubble's 16 Mpx was bleeding edge. AFAIK, it was sufficient to take advantage of Hubble's ~0,1 arcsecond narrow field resolution.
isn't ESA's Euclid designed to do pretty much the same thing as roman? and up there NOW!
@jrw9985 Umm, good point. Field of view, spectral bands and sensor resolution overlap almost completely. Even the stated goals are similar, except for Roman also carrying a coronagraph for direct imaging of exoplanets.
All the best space telescopes point at the ground.
True. Actually, they don't get much bigger than Hubble. There's a limit to how big you can make a surveillance telescope.
Epinephrine is also common in the human body. Is 30% of it there destroyed too?
If the universe stopped expanding what would happen to the vacuum ???
The idea of dark big bang sounds interesting, but it also sounds like quite a reach. One thing I never understood about dark energy causing the universe to expand, and galaxies to fly away from each other, is the fact that in the far distant future the Milky way is set to collide with Andromeda. Confusing
11:00 Or you could be mistaken for a Chinese spy balloon and shot down by an F-22. Lol
Fraser every day 🥰
10:20
Flat earthers don't have 175,000 dollars...
They can pool their money.
@4:31 "If you run the clock backward the entire observable Universe... was once the size of a grapefruit." I prefer to think of it as a mango. Sweet vs. tart... that's just me. 🤓
I prefer potato. Modest and versatile and much more common and relatable.
When it was that size it wasnt observable. :p
@@deltalima6703 Ah, but it was consumable. 😋
If epi pens get affected by cosmic Ray's maybe a whole new field of study will be finding out what other compounds change in space... maybe even human physiology...maybe not things that reprocess relatively quickly but some things like brain matter doesnt recycle for yrs
Yeah, I'll bet this discovery is making NASA look carefully at every chemical they fly to space.
@Fraser Cain the space station gets hit by a lot of cosmic rays, does it not?
Fraser, can any planets survive in the center of our galaxy?
If anything, smaller and solid bodies are less subject to tidal disruption. Any planets that attended stars that are now at the center of the galaxy probably got thrown out of their orbits by the numerous close passes with the BH and other stars, so they would take up independent orbits just like those of the stars. We just would not see them.
That neglects the question of whether there _are_ any planets there. The oldest stars formed from material without elements from which rocks and water can form.
There is Trantor, of course. The newer novels mentioned it being some distance from the true center of the galaxy, if memory serves. I've not seen the new series on Apple TV. But, I think a fine up-to-date interpretation would be for it to be a "rogue planet" without a true sun, but the Imperial Palace (the only open ground remaining) is lit by numerous nearby stars.
@@JohnDlugosz Thank you, Sir.
the order ou read the t nes titles in the intro lead me to believe that kids discovered thr dark big bang oops.
I am too young to remember hale-bopp and I have kids if my own.
Hi Fraser great video. ok ok epi pen thing, cool, China's fuel tank yeah that's exciting and you know you should be blaming the lazy Oort cloud for your lack of comet joy 😆not the universe at large but the dark matter big bang. 🙄 Yeah you see that eyeroll, in fact my eyes are still rolling. I mean seriously. How about we all just repeat " we don't understand gravity over large distances yet" a hundred times. I mean this is really taking the unicorn hunt to a whole new level 🤦 dark matter big bang 🙄 that's cute.
I didnt know you were an expert on the topic. How come I never heard of you?
@@deltalima6703 you don't have to be a professional astro to have an opinion on BB theory in fact some of the greatest insights in astronomy and astrophysics have come from so called amateurs, who are passionate about the subject matter. I'm busy writing a sci-fi book not papers right now that's why you haven't heard of me 😆 I'm hiding in my little book cupboard scribbling away
the whole world "size of grapefruit" , how can it be compared when nothing else existed, not meters, millimeters or inches?
If you look out in one direction to the very edge of the observable Universe, and then in the opposite direction, those two points are 92 billion light-years apart. If you could then hop in a time machine back to end of inflation, and then measures those two points again, they'd only be a few centimeters apart. Distances still existed at that point in the Universe since it was after the Big Bang.
My doctor said I shouldn't eat grapefruit. Is this an argument against the big bang?
Dark Matter is where physics dump the unknown so their equations work.
Sooo..If traveling near the speed of light...when u sing a song and when the transition reaches earth does it sound like the chipmunks since time slower on earth?
Hah, yeah. It would get very hard to communicate at high speeds
I think its funny that the Japanese rockets look so, um, maybe familiar to them, morphologically.
All rockets look like penises
Some billionaire out there should get his name plastered all over Hubble and get that telescope boosted right out to the edge of the solar system, imagine the pictures of the minor planets it could take...and of course all the fly by ones on the way out there !
Just clarifying. Once, the universe, through the process of inflation rapidly expanded to the size of a grapefruit.
Just clarifying: The universe was always of infinite size, even at the big bang. But the visible part was once the size of a grapefruit.
Water for the epiepen...
..Big Bang or Big Suck?...Suck would remove the confusion over Dark Matter/Energy..
don't know about dark big bang. My computer sim implies something akin to early dark energy condition phase transitioned into a condensed form and initiated inflation leaving dark matter as a non quantum information relic.
4:45 inflation how is it possible, that inflation came to be? not just economists need to rub their eyes and gasp in astonishment!
for the cosmic one, the explanation is in rocket science and electro-tec, maybe.
in an electric conducting circuit, there is the internal resistance of the battery and the external resistance of the loop. the max power flow in Watts is attained if R_int = R_external; it is called "power adaption".
in rocketry, the photonic(impulse transfer)rocket is the one with the highest ISP and speed!
in the early blinks of the Big Bang, the electromagnetic and the weak force were still united. When a state/condition was reached so that "power adaption" between particles with inertia and quanta without inertia happened then a 3D-Photon rocket ignited and a short time later fizzled out again. it could have happened more than once. Another way to try to explain it is to say that in the early times, there were short peaks in opacity ( opacity = 1/transparency ).
Thank - you . ( 2023 / Mar / 11 )
Hm
I had a nightmare where I got pulled over by a gay cop and I refused to hand over my license & registration. I guess because he was wearing a rainbow pin & tight shorts I should try that stupid "sovereign citizen" crap. Instead of shooting me like a normal cop, he came over to the passenger side and started pleading with me through the slight crack I'd left in the window. He was trying to calm me down, and started talking about normal stuff like black holes & dark matter. In fact he kinda looked like... You. That's when I realised I had fallen asleep listening to this show. I woke up so terrified I just had to type it out. Me? "sovereign citizens?" GAAAAHHHH
Like
From the big bang, all that information or material/matter probably spewed from a black hole from another universe. and still is spewing. The other universe must be very old.
I have a question for Q & A.
Why Russia is so advanced in the Rocket technology compared to the NASA or even military rockets are way more advanced?
(Explanation, you don't need to read this) Is it possible that the US cannot catch them for so long? This is happening for years now and especially when we know that Russia had financial difficulties compared to the US.
Even if we are looking what they developed for their military, they are so advanced, much more than the west.
Can you please explain why is that? And what NASA is doing to surpass them?
Russia was advanced 10+ years ago. Not anymore. 10-20 more years under current conditions - and nobody will even remember that Russia "could into Space".
By the way, as these 6 red dots (old galaxies) recently discovered in the James Webb space telescope imagery point out, cosmology might have to be revised fundamentally. I bet on the demise of the universally accepted Big Bang theory which depends very simplistically on reversing "mechanically" the expansion of the universe to a ridiculously small initial point of matter that are supposed to have contained all the matter and energy of the universe that exists currently.
Nope, the universe is not a giant mechanical structure, with gear like watch-precision sequence of events that can be just rewind anticlockwise to its initial state! What a childish perception/analysis of a very sophisticated/complex and fine tuned universe! Time for some grown-up, more scientific cosmology thanks to the James Webb space telescope.
Nature will reveal the truths about itself, we just have to keep searching. But what alternative theory do you think better matches the observations so far, like the ratios of hydrogen/helium/lithium, the cosmic background radiation and the speed that galaxies are moving away from us? Any other theory has to explain that equally well and make new predictions that are testable.
@@frasercain Similar to Relativity and Quantum mechanics theories, both of which we know are at least incomplete, more data/observations are needed to replace them, so is the Big Bang theory.
James Webb telescope has just started to give us very promising hints in the right direction but there is still, at the very least, 10 years worth of very valuable and quite possibly unexpected numerous future observations, measurements and data that I am confident will revolutionize our knowledge of the universe not just replace the Big Bang theory.
A wooden case.
Why is there so much time between launches of Artemis 1 and 2? I understand that they want time to react to what they learned, but two years seems excessive.
Could you please avoid illustrating the Big Bang with animations like the one starting at 4:05? This enhances the popular misconception that the Big Bang was an explosion happening at a specific point in an already existing space.
