Haven't seen Olivia in awhile.
We'll have more of her in September and October!
Yes.
+SciShow can you guys do a video on Titan
It's hard to film there.

I hope the new fundemental force is real. That would be amazing.
It might make all physics simpler. Like, a force to explain all quantum mechanics
Or one step closer to unified field theory.
A lot of things are amazing, but it's important to stay sceptical and make sure it is really there before getting excited first.
***** That would be from the theory side of things yes, but nothing like a phenomenon that a scientist doesn't understand that will get them excited. It gives them the chance to test and try to find a new thing.
I don't mean t be a buzzkill, but do keep in mind that arxiv.org isn't peer-reviewed, (people post there before submitting a paper for peer review to reduce the risk of reviewers stealing ideas and publishing first), and the high-energy physics (H.E.P.) categories have a lot of cool-sounding, but completely bogus stuff amongst the legitimate work. All of the categories have that issue to some extent, (e.g. there are some hilariously bad papers about P vs NP), but the H.E.P. categories seem to attact some particularly wacky submissions.
How can there be a fossil 3 billion years old if the earth is only 2016 years old???
XD
Wow you are an idiot
Jaden pls
Burn atheists!
+joblessalex
You just told 1/5 of America, even children, that they should burn because they don't have a similar viewpoint to yours on life.
The fifth force is clearly The Schwartz.
Idk about you, but I feel the new fundamental force should be in the title, not the oldest fossil
That, dear sir, would be clickbait. You can be pretty skeptical about such could be mayor deals, I mean that is on the same level as: Hungarian scientists have defied the laws of thermodynamics.
why not both?
+
Agreed!
The fundamental force is just a hypothesis. The fossils are a more reliable discovery. I'm glad scishow didn't mislead or try to overhype viewers on this one.
Harambe is now a fossil. rip
I believe his body flesh is probably still rotting away, as horrible as that sounds ;(
+Will Thomas meh
what if someone had the skin of harambe as a coat or a rug just imagine how much that would be worth...
But his body was donated to science... Harambe will rise again ( ͡° ͜ʖ ͡°)
Can you do one on cerebral aneurysms? I had one rupture at 19 and would love to learn more!
Just stop
how are you alive
Keep persisting man. One day...
+nickjer2012 I've known two people who've had cerebral aneurysms and survived. It's the slow leak compared to a artery bursting. Like what happened to my dad. He died in a minute.
On one hand I really want to see them answer your question. On the other hand with this level of persistence I wish you'd 'learn more' with the incredibly vast tools at your disposal online.
I have a lot of serious illnesses and I can't imaaaagine not doing my own research to understand more by now.
I'd want to see scishow psych. My chem teacher says psychology isn't a real science. My psychology teacher disagrees.
it's a soft science.
psychologists just recently started using scientific method, and keep making fundamental mistakes
so technically it is science, but to say that it provides knowledge would be overstatement
Psychology is more of a social study than a hard science. Be it a social or Soft science though.
Just mention how the entire subsection of psychology know as willpower depletion went up in flames half a year ago; they'll love that.
+Dovahbear Physics is just based on math thou.
you should just call it PSYshow :)
+
honestly, what I'd mostly like to see is Sci show chemistry. although, those all sounds really really cool. just putting it out there to voice it :) you're all awesome and stuff!
I hope they vote SciShow Life
+

I have been dying for a biology scishow!
Whatever.
Bruce Willis already found the fifth element nearly 20 years ago.
+Drop Bear An element is different from forces.Elements are the ones you see on the periodic table of elements while forces are the ones mentioned in the video,gravity,electromagnetism,weak interaction and strong interaction.
+Lego Ang Meh. It has "fifth" in its name and its vaguely science related. More than enough for an average person to find that connection clever. Just to be clear, i agree with you. But nobody cares...
thank you
oldest fossil ever found? - they've met the mother-in-law
That reveal got me way more excited than it probably should have
Amazing! I just taught a class on earths history in spring, cant believe the timelines we had students made already need to be updated!
They haven't, it hasn't been proven yet. Please dont teach your kids things till its proven
"...and that's good enough for me." says Hank!
Simply Adorable
I literally just read about the early life info from this video a couple of hours ago. I should have just waited for this video! XD
SciShow Psych! Wish you'd had one of them three years ago in time for my degree, I used one of the videos to better understand a paper I actually needed to read this term, it was great :D
Maybe life got here with th big bombardment
Probably but we don't have enough evidence....
The intensity of something slamming into earth would be just too great for anything to survive, even without an atmosphere.
+Dovahbear True. I have heard of some organisms simply going dormant when exposed to vacuum. I think it as a water bear I read about.
Nope life couldn't arrive with it because life requires water
As already mentioned that is a plausible theory but hard to prove. One reason is that life and Earth lived and changed together, affecting each other. Maybe life came from somewhere else but Earth is definitely its home now!
Patreon supporters better choose Psych, or ELSE.
Caitlyn Jenner isn't a hero.
Ew no. One of the least empirical (and thus reliable) branches of science I know. Besides they'd run out of topics in like a year. SciShow LIFE all the way (which would still give them the ability to cover psych topics).
.......and its name is Bruce.
Quick Question: Do women ever have to pay child support?
Yes if the man gets custody
Trick question. Men never get custody.
there are cases were the man gets custody but the ratio supports the idea that the court is discriminating against male parents in these types of cases.
I'm a divorce child myself.
It was just a joke. Who is exited for the explanation of the science though!
When I was a kid my mom tried to kill my infant brother with a knife and spent a while in a psych ward over it. She won the custody battle for my brother a few months after getting out.
thanks for the late night upload.
Read this in the newspaper last week, so cool!
Might be just me, but, a new fundamental force would have hooked me faster than the fossils :b
The new fundamental force is _much_ more dubious than the fossils, so I'm glad they didn't put it in the title as clickbait.
New force should be called Harambe Force
No Patreon History? :P as a Historian working on that would be like a dream. But I'm okay with just watching it too.
i want all 3 of those new shows to happen! hahaha :D all 3 sound like they'd be good ones!
SciSchow Health!!! A UA-cam channel that helps explain healthful practices in a scientific but still straightforward manner could change lives. The largest demographic of people who suffer from health problems do not have access to the knowledge that might have prevented their issues in the first place.
I am happy you included the papers with this.
SciShow LIFE!
SCISHOW LIFE! Hank, we haven't had a biology science communicator witb the clout the SciShow has since Steve Irwin. Science communication is overwhelmingly dominated by space, physics, and engineering.
YES NEW SCISHOWS!!!!
SciShow Health would be AMAZING! Think of how many people Google health related things, SciShow health would get soooo many views!
"New Oldest fossils" LMAO
Oxymorons.
Aye. It clear that they mean that they have found a new fossil (one that was not known of before) that is older then the oldest fossil known before. English can be quirky but this is correct English.
Scishow PSYCH would be so cool. Patreon people please make it happen!!
So much want for SciShow Psych :P
Sci Show Life
+
Scishow Psych sounds fun. Wish I could afford to be a patron. I'm excited for the new show though!
Scishow is the first video I'm watching on my birthday wow
I love sci show!
I'm not on patreon, but I really want scishow life to be a thing!
I hope they actually do make a show called scishow life
I dozed at the second part.
Caveman had a sort of Nobel prize. This day 50kyo, Uuug was awarded the prize for the discovery of log rolling, and received a hug.
I'm still surprised to see there is no Heavy Metal band called The Late Heavy Bombardment. What are they waiting for ?
(And Thagomizer, for a Thrash Metal band, would be perfect as well. :)
Same thought here. I'm picturing slow, moody, heavy, loud, with lots of chunky feedback...
Sounds good
So... let's start this band. What do u play?
Nothing (yet). When I start an instrument it'll be drums. :)
+Piffrock Perfect. We'll just make it a punk band instead. Then no one will be able to tell that you can't play.
Sci show life
+
WOW! The title of this one should be about the fifth force! What crazy news!
Late heavy bombardment sounds like constant asteroid impacts like in a warzone. But we are talking about cosmological events. What were the timescales between impacts in that time?
scishow life

2 interesting news bringing many more questions, that's the 'feels good' part of science.
Wow! And WOW!!!
Scishow psych sounds amazing, maybe because I'm a psych major but hell yea!!
I would like to see Scishow Life, but I also think that you could do psych in Scishow Health, with just different segments for anatomy/physiology and the actual disease and medical doctor side, and one for the psychological side of things.
I want scishow life
SciShow Health sounds neat
I'd like to see SciShow Health.
i'm still waiting on a scishow tech. it's inevitable, i just know it.
fascinating!
science man, never stops proving you wrong
i'd be interested in any of the next channel ideas. but man, how do you separate psyc/life/health/bio/chem/physics? woof.
0:31 AGAIN? Gosh, it seems like the record keeps getting broken every month!
SciShow Health!!!!
Not to rain on the parade here, but it is already pretty well understood that the late heavy bombardment is the casual factor of life on earth. Meteor impacts create organic molecules and amino acids that were needed to fill the environment to the point of critical mass that allows for self-replicators such as RNA precursors to form. Life began because of and simultaneously along with the late heavy bombardment. We've reproduced the early earth conditions and watched replicators self assemble in lab settings. Interestingly enough, the inanimate matter such as stone and clay and minerals were just as important as the organic molecules themselves. The early rocks and clays provided not only surface areas for the necessary chemical reactions to take place, but also provide a good amount of the actual work involved in getting replicators started due to the nature of the bonds in the rocks and minerals.
This is awesome that we have found fossils this old. I wonder how old the fossils will eventually get.
they'll be even older tomorrow. can you believe this.
bahaha, that actually made me laugh. (dorient)
you should add the fundamental force to the title. If someone was trying to search through your videos for the second news story, they wouldn't be able to find it without reading the description
scishow health for my vote
Life's a hard thing to eradicate. Fortunately there's heat death.
I'm a little fuzzy on the subject, but we don't know of a boson that transmits the force of gravity, so could this potential new boson be that?
Gravity's is the Graviton.
+KR P we have never observed a graviton, so you can't say it yet
scarheavyfox Indeed, it has never been observed -but how is that at all relevant to the question?
The hypothesized force carrier for gravitation is called a Graviton, the predictions for graviton properties are a bit flaky but I'd imagine if this supposed particle was anywhere near -it wouldn't be refereed to a "5th fundamental force" but this is my supposition because I haven't even looked at the abstract of the paper.
It's so neat how the asteroids hitting earth were bringing various minerals and water pretty much setting up earths environment for life
3.7 billion year old life under such harsh conditions suggests life will arise wherever local conditions are right.
Question: Why some batteries (in our phones and hoverboards) are exploding?
Please patrons I has no money make it SciShow health
4:17 ... yeah, that seems like a more likely pattern...
Psyche sounds like it would be awesome
If they find a fifth fundamental force, they should call the particle a V-Boson.
PSI SHOW PSYCH!
it's a play on words :D
This discovery just ruined the first lesson of my biology class and I'm okay with this
What if there was no 'late heavy bombardment'? We think there was because of things like all the craters on the Moon, but those craters are problmatic, like how most of them are perfectly round and flat-bottomed. Many other craters in the Solar System share this problem, or other confounding problems, like being bullseye craters, or even being hexagonal in shape. But all these issues are resolved if we interpret these craters not as impact craters, but as plasma discharge craters. Large plasma discharge events leave markings exactly like what we find all over the Solar System. No Late Heavy Bombardment, no life survival problem.
I imagine that people who have studied earth science more thoroughly than myself will find my question to be obvious, possibly even cringe-worthy, so apologies in advance:
Radiometric dating using carbon isotopes is usually reliable around 50,000 years or so, so I'm curious as to how we determine the age of carbon that is greater than 45,000-55,000 years? I could understand other radiometric dating being used to determine the age of the fossil, but can say zircon dating be used to determine the age of carbon found in the fossil?
I don't expect anyone to write me an essay over the question (on the off-chance someone wises to do so, please do) so something like a link to a reliable source where I could learn more about the topic would be just as appreciated.
Would like to see samples of potential new shows.
Written history is what counts, lava rock has writing in it, light is slowing down is the new theory
I was wondering. Who is in charge of the background color? Today it was beige, but I have also seen you do green and blue-ish I think. How do you decide? Could you do purple? Does it have to match Hank's shirt?
Pretty sure the X-Boson was ruled out a few weeks ago at CERN c'mon guys keep up
Add Scishow Pysch. It will be great to learn why we behave the way we behave. :P
SciShow Health!
can you do a video on the physics of wingsuits?
A team of theoretical physicists in California? 'The Big Bang Theory' :D
Lmao too good
Stromatolites are amazing!
wasn't that potential new force data scrapped last week as the bumps in the data didn't show up again so it was said to be a statistical anomaly?
Sci show Life!
How do comets and asteroids 'crashing into each other' form a planet? The minuscule gravity of each couldn't possible overcome collision impact energy to hold the resulting material together.
As you told it yourself, asteroids have a very low gravity, so there's no reasons for them to crash into each other.
They just gently touched, because in the protoplanetary disc, all asteroids and other particles were moving in the same direction at really close velocities.
The protoplanetary disc was nothing like the asteroid belt for example, which is more chaotic. It was similiar to the saturn rings system, were we regulary observe some particle clumping in order to form larger objects ( those objects are destroyed afterward by the tidal forces of Saturn ).
I hope I answered your question. I'm not english so I apologize for any mistake I could have done.
Who's thinking "particle of the gaps"?
So some shity microbes survived a f#cking non-stop meteor raining and the scientist sayin' there cannot be life on Mars cuz its...cold? Yeah, seems legit.
yeah, the reason aliens cant survive on mars isnt that its cold,, its because mars has no magnetosphere which protects it from solar rays, so basically every second mars gets about 1000 joules of radiation because of its lack of magnetosphere
I enjoy science, I like the way this show explains things. This show makes learning fun. I just want to add that the oldest living dinosaur is my ex-mother-in-law.
It's good to point out that evidence of late heavy bombardment is found on the moon. The time scale, if I remember correctly, is too large to find evidence of late heavy bombardment here on earth.
Any news on this 5th fundamental force?
So... life came in asteroids from space:
so is it actual life or just complex compounds like proteins/amino-acids?
Actually the Late Heavy Bombardment was quite conducive to life for thermophiles and hyperthermophiles - check out Abramov, O. & Mojzsis, S. J. 2009. Microbial habitability of the Hadean Earth during the late heavy bombardment. Nature (London), 459, 419-422.
scischow health would be awsome!!
