How do you think the universe will end?
If the universe ceases to exist would we have ever existed ourselves 🤔
If Matter cannot be created or destroyed, what happens to matter that's ripped?
hopefully without me.
With my balls disappearing again
Nothing is set in stone, all of these are theories supported by data and the very limited knowledge we have gained on the universe. Anything can happen we don't or probably will never truly know.
I came to Startalk for the science, but I stayed for the friendship between Neil and Chuck.
Well said
In some ways, maybe the real destroyed universes were the friends we made along the way.
Again, I apologize about that.
Chuck said it best: we won't make it out of the century
Strange.
i'm also just hanging out with the guys :)
The universe may end, but the cameraman still won't die
Fr fr
Eternal witness.
Time to pick up a camera
Thank you so much for going back to the studio. Much better audio quality and no delay between the speakers.
I think this might be an old episode. But I could be wrong.
Neil is so good at explaining stuff so that I can pick up on what scientists theorize without making me feel dumb.
Every time Chuck says: "OK"
"right"
Alright
or finishes Neils sentence with him but starts after him so hes already heard it 😂
"Yes"
“Wow”
😂 I’ve been watching you explain the universe ever since I was very little and you have played and still continue to play a huge role in my love for space and science in general thanks for teaching me most of what I know about space and how it all works
5:27 Chuck, you were there for the Big Numbers explainer!
He should listen to Neil more , but he probably was busy thinking how to make a joke out of it.
he probably listens to neil for whatever period and forgets about whatever they have recorded later in the day lmao
Neil just forgot who he was talking to
Chuck went with his initial thought and went 10x100. It happens lol.
I can almost guarantee Chuck knows what a googol is. I think he’s just playing the part to make the show feel more informative. After all, you never know when it’s someone’s first star talk episode, and it can be helpful when learning new information if you have someone else learning it as well giving feedback
Chuck has been doing this for so long; he has been learning from Neil for so many years that he should be given an honorary degree. I mean, I get the sense that he knew everything discussed in this episode (except the one math question) but he is a consummate professional so he plays along as if he doesn't. I'm starting the campaign right here, right now: Give Chuck an honorary degree!
Dr Chuck!!
10¹⁰⁰ is 1000
He's smart but that math error is really odd.
He just forgot I'm sure he knew that google is 1 with 100 zeros.
Don't underestimate Lord Chuck
Or maybe Chuck was trolling Neil. Chuck said 1000 with such confidence & Neil's face palm. 😂
Hi star talk thanks for all the great content.
0:10 Chuck, you owe me a pair of eardrums.
i've been pretty outspoken about their new set-up and whoever they've hired for the production and this is yet another example. what a rocky ride these new episodes have been. My bluetooth speaker is fine, but now my neighbors think I killed a pig lol
yeah seriously, paniced and almost turned it off bc of that
It ends at a restaurant. Everyone knows that.
A restaurant, huh?! Get up and fold yourself in half 12 times
@@Whuzzer Douglas Adams, my good man. Learn a book.
@Whuzzer whoooosh that went straight over your head 😂
@CliffordLake you can get your point across without insults. Clearly we are from different generations so references will be different. Lighten up Clifford. Insulting people for not possessing the same knowledge as you in the comments section of a Startalk video? Big ego. Little man.
"A restaurant". Don't be ridiculous.
Millaways is THE restaurant.
Entropy wins in the end 😔
Why are you depressed 😐? Do you even understand the REAL truth of entropy or are you just a believer?🧐
Professor Brian Cox's explanation of entropy in 'Wonders of the Universe' is probably the best breakdown of it (no pun intended) for the sweaty masses. There's even an analog in the form of a sand castle. #Weeeeee
@@SLIDEMONGERZ well you don’t need a whole bunch of information just to explain simple such as entropy 😐as the process goes like this ➡️↗️➡️↘️➡️➡️↗️➡️↘️➡️➡️saying entropy ALWAYS increases is flawed as if you say entropy never decreases then we would never die as we would continue to grow forever 😑
In the past we had Albert Einstein...
Now we have Neil and Chuck!
Einstein made contributions to physics. His brother Frank made a monster. 😅
Fun fact, if we go down the heat death route, there’s a stupendously, ludicrously, unbelievably small chance of a new big bang occurring due to quantum fluctuations in an estimated 10^10^10^56 years…
Cause my brain isn't working yet, can someone post the number in 10^x
10 to the power of 7600@@sillyWillieBilly
Bruh that is way bigger than 10^7600. We can't write it in the form of 10^x, that's why he said 10^10^10^56. To even write it in the form of 10^10^x would be 100000000000000000000000000000000000000000000000000000000. 10^x would require writing twice as many 0's are there are stars in the UNIVERSE.
@@NicholasLayton yeah, the third 10 would have 56 zeros, that number is 100 octodecillion, the second 10 would have 100 octodecillion zeros! So it would be 10^whatever the name of that big number is…
Your idea of a fun fact is MUCH different than mine. 🤣
😮I love your channel. Thank you for sharing your expertise with us
love from Ethiopia
Me too
I'm glad I'm alive at the same time as Neil and Chuck. They have such a great way of explaining science to the masses.
We need to figure out a way to digitize these two so they can keep going.
100 % Agree ❕️
An AI Neil and Chuck are the astrophysics Statler and Waldorf that the world eternally deserves
Weirdos ..
Who’s down for ice cream?
I was having dinner while watching this, and I just choked on myself at 5:18.
Lmao.. me too
You guys are so awesome and entertaining. I'm a long time amateur cosmologist, and keep pretty up-to-date with the latest cosmology theories and discoveries, but I still love to tune in to StarTalk to enjoy the banter between you two. A++
Nice seeing Chuck thinking in the same vein as Neil in this one. More scientific than comedic, with Neil providing more comedy. Love it!
Love you both. Stay safe.
I love the new edits on StarTalk. Illustrations make it much easier to comprehend things Neil explains.
I like how the least accepted theory gets the ad break xD
That screech spoke volumes 🤣
I would love to see Neil talk about astronomically significant man maid structures ,and to give us his opinion about the pyramids and gobekli tepei from an astronomical point of view.
I would like to see a Egypt explainer on the pyramids .
The best part of this video is learning about Ground News.
As "news" became more polarizing on each sides' major platforms, I stumbled on StarTalk's video with the creator of the Ad Fontes Media Bias Chart. From then on, I simply only read stories from those center/top agencies, such as AP or Reuters.
Ground News not only utilizes this monitoring platform, but two other major ones I never heard of, and looks to do it in an easy to absorb and navigate interface. I am excited to subscribe, yet ultimately sad that I even have to. Thanks StarTalk!
the "center" is just as much a biased position as the "left" or "right"
could you please give an exact date so i can make sure to watch the complete bucket list of TV shows i want to see before the end comes.
Chucks scream startled my Cats 😂😂😂
Somewhere in a parallel universe, Physicist Bill Waterson draws comic panels in his spare time that he calls _Kelvin and Hubbles_
Chuck was scared the entire time he was holding that rubber band. 😂 Another great episode!
I appreciate a fine, uplifting Star Talk episode at the end of a long day. Thank you!
Probably not the coziest video to fall asleep to, but I’m here to try it anyway
What a fun one! Loving the content from the office again! 😊
I love that you guys ended with sleep well because at the time of me watching this I'm about to go to sleep.
Neil and Chuck for 2024!
Love the content. Thank you
After the galaxies use up all their gas could t they just switch to electric? 🤔
That makes no since 😐as electricity all ready exists in gas 😑ever Ben in a thunderstorm?🙃as you failed to mention the irony if you scientists say all galaxies will burn out that does explain why they came into existence if their was no gas to create the galaxies in the first place 🙃
@@jettmthebluedragonThat was a gottam joke.
Bro I love seeing y’all interact. Makes learning fun haha
I just witnessed the birth of a StarTalk video. Such a privilege.
Great Content
the clarity you bring to your subjects is beyond impressive!
The universe is always ending. That’s just the front of the ship. Here and now is the brain.
The universe may not end in my lifetime but it may end in my ghost time and still scares me.
^ T H I S ^
If there is reincarnation (or effective technological inmortality); this is something that is going to haunt us literarily until The End.
The lifespan of the universe is on such vast, incomprehensible timescales that it's effectively infinite. So I would worry less about the universe ending and more about your ghost being forced to experience all that.
I think i will be responsible for the big rip (i fart really hard)
Hello, I just recently heard about the concept of “alter magnets”. Can you please dedicate a video to explaining the law of magnetism, what “alter magnets” even are, and what the implications of “alter magnets” might be? Thanks, love the show!
Fire
Or
Ice
That deserves another thumbs-up.👍Sleep tight everyone.
This is by far the best StarTalk episode i’ve seen 🤣🤣
I've been using Ground News for about 3 years. It is excellent.
Sounds more reasonable than the sky wizard coming back.
Are you referring to Jesus?
@@lschastain77Sky daddy
It's 3:30 am in India and here I am😅
A Simple sentence like"A page od the universe have been removed and they will not even know IT." Is making me think If we could miss out on something important
Had a big Rip, big crunch, big squeeze and big bang after Taco bell
The universe ends with the big rip? Man. It ends several times a day at my house then.
You can convert into the big bang with a lighter.

@danielvermeer3363 Another internet troll...and Friday is still 3 days away.
We want Cosmos season 3
We love that show and we love NDT.❤❤
They just reclassified cannabis and now the whole universe is ripped.
Chuck gonna need a work comp claim to get that finger checked out. LOL.. You guys are amazing.
Educational Entertainment
to the MAX ❗️
I Love StarTalk ❤
You can tell he’s heard these scenarios from Neil around ten different times the way he’s finishing the sentences for Neil 😂
U maker a good serious comedy team! Love it❤
Bro 5:18 😂😂😂😂😂😂😂😂😂😂😂😂
I think Chuck thought he said "ten times a hundred" not "ten to the hundreth power"
Thanks for sharing 😀👍
Sir Degrasse. Will you ever do a live stream, so we can ask questions live?
I will create a new universe for y'all after 100 likes
Too bad they aren't taking you seriously 😒
Can I get a "Trust me bro" Guarantee?
can believe this comment doesn't have 1000000000 likes shame on you guys 😂
@@MaxBenn Trust me bro 🥹
Who needs another universe,
People worry about the Universe ending in 10³⁰ years but no one cares that humanity won't make it to 2030.
lol we all 💀ing in 6 years? That’s crazy
No Sh!$
Very optimistic 😂
We'll make it to 2030 but it's not going to be pretty due to A.I. and automation decimating the workforce. Climate change accelerating also means large parts of the Earth will be uninhabitable so mass migration and water wars will be common place.
Making it to 2050 is going to be the real challenge.
Awe, How many end of the world times has been said by human kind? Ending six years? Most likely not.
Awesome treadmill information and motivation!!!
Great podcast!
It ended when I found out my ex was not the father.
😂
But you're a dude
Wouldn't you and him have worked that out already?
That's what you get for being a slapper
Oops
I am the father
this is awesome, and the animations too!!!
That intro was the stuff of nightmares. Kudos editor!
Neil is accepting Level 8 Stellar in Technology(StarTalk). More complex level than me. Next Level 9 for him is GalaxyTalk. Then it is over on the Technology level.
Levels
1. **Stone Tools**: Level 1
2. **Agriculture**: Level 2
3. **Industrial Revolution**: Level 3
4. **Electricity and Telecommunications**: Level 4
5. **Computers and Internet**: Level 5
6. **Space Travel and Colonization**: Level 6
7. **Advanced AI and Singularity**: Level 7
8. **Interstellar Energy Harnessing**: Level 8
9. **Galactic Energy Harnessing**: Level 9
Neil's laugh is delicious to hear, I feel all warm and fuzzy and makes me remember to hit the like button everysingle time.
Listened to this in bed before fallingasleep. Laughed at the end
Some studies trying to tackle the Crisis in Cosmology may be hinting at the expansion of the universe not being constant and that it may vary over time and space, but still nothing conclusive yet.
Also you should do a separate video on the fourth hypothetical apocalypse scenario, Quantum Vacuum Decay.
I love their relationship! It's almost like father and son!
I searched what 10^100 looks like written out, and my head hurts from trying to comprehend it.
I came across Ground News the other week. Looks very cool. I'd pay for it if it covered New Zealand news.
How fascinating! I'm wondering if dark matter could be the substance our universe is originally made of. I mean a kind of infinity, where dark matter serves as a base for everything. If I understand correctly, the universe produces this kind of matter. So everything would transform into dark matter. And if we assume that dark matter is expanding itself (not space), we could also assume that it could produce matter while tearing itself apart...
There is a visual video of the end of the universe (Timelaps of the future a journey to the end of time) they also added some of niel's lines there.
6:03 A line from a famous melodysheep video "End of time", where NDT himself has said this iconic line.
I am gonna set my alarm clock 2 mins before the ending, just in case if I don't wake up and miss the fireworks! 🤩🤩
Its like a baloon which is expanding and the dots are going further from each other, at max expansion the baloon will pop and the dots will be together in 1 singular dot , then another bigbang
Awesome ending to the episode! Reminds me of the Aiel saying (from the Wheel of Time series) "Sleep well and wake." Basically, I hope you don't die tonight! ;)
I think if our universe is indeed finite, then the big crunch is most likely.
Because unless our current universal iteration is the first then something either caused it externally or it's cyclical and i'm not going to add more issues with the external idea.
Now just as in the big freeze eventually we couldn't see other galaxies or stars it's possible in our time we simply cannot observe the collapse because we have not yet reached that phase in our universe similarly.
However the evidence implies it's likelihood, because saying currently we somehow exist in the history of all existences final end is ridiculously improbable, statistically when all data is accounted for the cyclical idea is astronomically more likely given our understanding.
Light thinks it travels faster than anything but it is wrong. No matter how fast light travels it finds the darkness has always got there first and is waiting for it.
Terry Pratchett RIP
Hello professor, its nice and honor to watching and hearing you . I have 2 questions if you mind to answer :
1_If we have a pool for swimming in space and closed from above to avoid water out can we swim and how much mass of body inside ?
2_on space ,o'clock tik tok tik tok will move slowly or normal ,
and a compass will take or show direction ?
I'm Akram Saleh from Saudi Arabia
I'm not a professor but I think I can answer:
1. Yes you can swim in a pool in zero gravity, however you will need scuba tanks or a similar way to breathe because the water will not stay on the bottom of the tank (in zero gravity, there is no down or up). So you can't come up for air, there is no 'up'. The water's surface tension will make it cling to your face, instead of falling off your face due to gravity like it does on Earth. Swimming in zero gravity is very dangerous.
"how much mass of body inside" : Mass does not change when you go to space, weight does. Weight is the force gravity puts on a mass. In space with the rocket engine switched off everything is weightless, the same would apply when swimming. However you and the water would still have the same mass as on Earth.
2. Gravity makes time run slower. Clocks therefore run a bit faster in space compared to on Earth's surface. The difference is very small, you need a special atomic clock to measure the difference, however people have put atomic clocks on aircraft and flew them around for a while and noted the small time difference so the effect has been proven.
3. A compass works by indicating the direction of a magnetic field. Earth's magnetic field extends a long way into space so a compass should work many hundreds or thousands of kilometres above the earth. A compass isn't accurate near the magnetic poles on the Earth's surface, it will be even less accurate near the poles in space, but otherwise should work until you go far enough away to exit the magnetic field.
Hi from Australia.
We want explain from your explored if you not mind, please
Chuck, you guys did a podcast on big numbers and discussed GOOGOL. HOW CAN YOU FORGET?😅😅
I love this subject and I'm glad my universe concept was useful here to explain the receding galaxies becoming out of reach. Hope we are able to figure out dark energy nature while I'm still around.
“I fear what we don’t yet know to worry” - Neil… that’s deep man

Universe expansion in quran
czcams.com/video/UUWdSKA_u9Y/video.htmlsi=I3-LWzB1RKwoyAqR
Niel : "You can do the math"
Lord Nice : "I can't"
Maths
You can do the math for the universe being infinite you can do the math for a finite universe numbers don’t physically exist and they will NEVER exist 😑you are worry about the universe never existing in a goggle years from now but you scientists failed to mention what happens a google years BEFORE we were born before we were born 🙃
"Melodysheep" has beautiful video about this subject. "Timelapse of the future" or something like that.
The sound track to that video is brilliant
“Ten to the 100? That’s a thousand.”
Neil died inside at that moment.
so did i
@@EnderCats8 Neil is like "I don't know if we can be friends anymore."
Looking up makes me happy.
I feel like we have no right to speculate about such long timescales. We already know that we don't understand dark matter and dark energy, we have no right to assume there isn't some other dark thing we have never discovered that could upend all of this. And similarly to how, if the universe keeps expanding, we will someday not be able to see anything outside of our own galaxy, we have no way of knowing if there is something else we can no longer see and there's another page of history that was ripped out and we can never know about
Thanks guys!
Wow!! Neil finished with an idea I had back in elementary school when I first learned about the Big Bang.
I asked my teacher if it worked like a rubber band and would snap back - and could that create multiple big bangs?
With the expansion, it's unlikely unless dark matter isn't causing the expansion but rather we are caught in a state of expansion caused by the force of the Big Bang and we have yet to see it slow down.
I think the idea of multiple big bangs was termed Eternal Inflation or something - where there was the idea of a "loaf" that is expanding and creating multiple universes.
I wonder if the expansion does actually slow and the thermo end is what occurs, would our universe just melt back into the loaf?
watching on youtube is a mix of me turning up the volume to hear neil, then sharply turning it down a dozen time an episode everytime they laugh or chuck speaks.
