And remember: The universe will end, but not for a while… probably
I don’t want to alarm you, but the world is going to end. All of this. Gone. And scientists are certain all of this will happen. On the bright side this isn’t going to happen for 4-5 billion years. It makes me wonder: In a universe bigger than we can fathom, across eons of time, could… all of it end? Everything? The whole universe? Yes. And it probably will. Here’s how.
Note: The copy of "The End of Everything (Astrophysically Speaking)" discussed in this episode was provided free of charge by the publisher. As in "the physical copy you see on screen." I also bought the book myself because I love astrophysics! But that version is on my Kindle :)

The Universe: expand
The big crunch: exists
The universe: "just when I thought I was out, they pull me back in"
Goerge costanza
Imagine the big crunch was the begining of the big bang and it was a time loop.
"How to Turn an Optimist into a Pessimist 101"
Kinda of the opposite
how to turn any person into a Nihilist generally
Don't be, an end to something usually means the beginning of another.
It's not exactly happening next week, and other phenomena will get us LONG before the sun belches, like HUMONGOUS species ending impactors, unless we obtain the means to detect and deflect something six miles in diameter or larger. They don't come every day, but they often do within a sixty million year cycle. My guess is the human race will wipe itself from the face of the galaxy LONG before that eventuality.
An Optimist, a Nihilist, and a Taoist walk into a chat room.......... can't wait to hear the punchline, guys !!! God luv you all !
The Big Crunch is the most fun, Heat Death is the most depressing, The Big Rip is the most terrifying, and Vacuum Decay is the most worrying.
The Big Bounce is better than the Big Crunch, because if we advanced enough, we might be able to survive it.
Worrying, yet nice to see it will not be a slow, painful, lonely death.
Heat Death is more likely to happen
@@catoleg the most reasonable outcome. The universe isn't made out of elastic, and gravity isn't going to suddenly get stronger. The laws of entropy suggested that everything is just going to get tired and fizzle out.
I have a personal theory
As heat death happens time ceases to exist any reaction can happen in reverse with equal likelihood
This continues for no and infinite time
Then the conditions are just right to trigger a Big Bang which could have totally different rules for the universe
"I never had more fun learning about how everything will cease to be"

Vacuum decay wouldn't destroy the entire universe, since it only travels at the speed of light, and dark energy is pushing space between galaxies faster than the speed of light. So if a segment of the universe starts vacuum decay then it would only affect the local area of the universe around that point, and shouldn't permeate throughout the entire universe. IMO
That would explain why it's happened in our universe before and not destroyed our planet

“Black holes ain’t as black as they are painted. They are not the eternal prisons they were once thought. Things can get out of a black hole both on the outside and possibly to another universe. So if you feel you are in a black hole, don’t give up-there’s a way out.”

@@miami_pete4646 yes, it's the curvature of space-time
@@ViratKohli-jj3wj A 3D curvature... It's weird
Well,very probable that matter and energy can get out of black hole,but not life,so ''don't give up'' it's pretty worthless for us.
From the common sense, they aren't black either, at least active ones, they are some of the brightest objects in the universe, if not the brightest. Not sure how they compare to supernovas, which are almost instantaneous objects, those put out a few lumens, also. Sometimes more than the entire galaxies in which they reside.
you forgot some... how about :
1) someone shuts power of to the simulation we are in.
or
2) the coming of the great white handkerchief.
or
3) someone somewhere invents time travel and stops time from happening in the first place
bet if the third one happened when that guy stopped time from happening everyone would go: *pop*
3rd one will create a paradox so
1) So we exist inside the simulation? We are just programs running? Then what does that simulation run inside of? Who created it?
2) I don't know what that is
3) If someone does that, time never existed. So we never experienced any of that. Unless that's assuming all time happens parallel to itself, like a billionth of a second from now and a million years from now are running at the same time, and when time is destroyed, all of the time that each version of ourselves experienced still happened, and ceased to exist.

Hi, you don't know me but if you're reading this and have some time to spare, it would be a great help to an existential question that I've been facing for a long time.
I think I see a "Great Filter" in front of us in the form of "Reward Death".
To understand what I mean by 'Reward Death', we will have to understand the relation between consciousness and reward. Now, for the sake of simplicity, we will divide the human experience into two parts.One deals with the mental capacity of performing actions and the other deals with reward( say reptilian brain. )
One can easily self reflect to realise that all his actions and thoughts are either to propel himself towards more reward positive future or away from some reward negative experience or possibility. This method of reward worked pretty good for all conscious beings that evolution has produced so far.
Now, by observing the exponential nature of the increment of adaptability ( or problem solving capacity ) of the living system, that we are a part of. One can easily entertain the possibility of so called “Singularity by ASI”.
Assuming you have solved the ‘Alignment Problem’, i.e. you can command it as per you desire.
As soon as you get your hands on the device, a very interesting thing will happen and the device will act as a ‘reward hack’.
As the basic nature of brain is to shoot for the most reward positive future and avoid any reward negative.
Your conscious feeling will have a very little disturbed trajectory towards more and more reward positive state.
The more reward positive you feel the more reward positive you want to feel. Eventually leading to reward induced coma like state that is ‘reward death’. This reward death will not be much different than overdosing of opium, cocaine, or any other reward hacking drug.
One might think now that he is aware of the fact. He will choose not to go in that direction just like one knows the happiness associated with drugs and yet choose not to take them.
But your body don’t feel a natural desire to consume drug thus providing you with a choice. This is not the same case with your natural desires for example SEX.
The more sexually aroused you are the more sexually aroused you want to feel and when you hit orgasm your brain breaks the cycle and you return to normal again
At the point of organism if you are provided with a choice not to break the cycle..
You will choose to prolong it a little more and then a little more and then a little more...
In the condition 'Reward death' your brain will stop the process of thinking and if somebody successfully force out of it you will I want to fall back in it with a urge worst then any addiction case we have faced so far.

Omg I've been looking for this tutorial all week
That metaphor of the caveman using friction to make fire gave me goosebumps, I stopped the video and tried to imagine our little earth, a rocky planet, being pulled into a black hole by such immense gravitational forces that our precious rock would crumble to pieces and accelerate to speeds unimaginable ultimately shooting out x-ray beams by means of friction.
It made me feel small and insignificant
From the standpoint of the universe, we *are* small and insignificant, just some slightly more evolved hairless apes on some insignificant rocky planet somewhere in the milky way, not even advanced enough yet to colonize some planet other than their home world.
Who knows what wonderful, but (to us) incomprehensible things are happening right now in other parts of the universe? The universe may or may not be chock full of other species of living creatures that may or may not come into contact with us one day, we absolutely don't know everything there is to know about our universe, we may be barely scratching the surface with the knowledge we already have.

"My friend, astrophysicist Katie Mack"
This is a casual sentence.
Vacuum decay relies on the standard model bring correct. However, this model only describes only 5% of the universe and is therefore quite possibly false.
She mentions this in the book, I believe.
And thanks for explaining how it would work. I had not understood that part before!
The problem with that reassurance is that if the Standard Model is wrong, we could all be killed by something else which we have no understanding of whatsoever.
Not that we would care.
And also, since the universe itself can expand faster than light, this means that a Vaccuum decay can’t affect the ENTIRE universe, only the OBSERVABLE universe: there will always be pockets of the universe that the Vaccuum decay cannot catch up to, because the fabric of space grows faster than the decay can travel through it
@@spindash64 All we know is that our observable sphere of 'hubble space ' appears to be undergoing a less than uniform expansion at this time....... that is a long way from ' the entire universe is expanding ' !
Hey thanks this helped a lot.
Amazing video as usual!
In ancient Buddhism, there are only 3 proposed ways ;D But the most common one coincides with the idea that the universe first expands, then stops expanding and then contracts until nothing remains!

So, what if that collapsing of the universe is what caused the Big Bang to begin with? What if it's a cycle?
what if every expansion and collapsation is just a heartbeatcycle (or inhalationcycle) of an even larger more universal creature? and what we call "dark Energy" is the effect of an ingestion of some stuff from different dimensions into our 4 persieveble ones?...
I really suspect that it is a cycle.. just a very long one. Big Bang, expansion, recession, Big Crunch - lather, rinse, repeat.
@@ChaosMagnet What started the cycle, if it is a cycle?
The big crunch will not happen. If there is a cycle it will be initiated by some other means of cosmic craziness.

Hey Joe! Biology question: I believe that there are sort of two strategies for animal reproduction. More offspring but less care for them or fewer offspring and more help so they survive. Then I noticed that papayas have huge numbers of seeds but peaches only have one. Is this a version of the same thing? Why such a large difference in the number of seeds?
Peaches were bred for less seeds
Peaches don't care for thier young........ the exception to the rule, that you are seeking is the octopus, breeds in very large numbers, ( often only once ) , teaches young nothing, and yet is intelligent, mentally adaptable, and perceptive
Who else saw a crewmate from Among Us floating in space? I just like it when you add these easter eggs in your videos! It really makes them more lively!👍🏻
Is "Vacumm Decay" "Strange Matter" in steroids? The idea of something so stable that can alter they sorroundings by touch its pretty awesome and scary at the same time, even in comic literature has been showed, on Green Lantern Lore there is a wall around the universe that whatever touch it becomes some kind of stone, not alive nor dead, and in one saga this wall breaks and it's debries floats in the universe transforming full galaxies into that stone by just one particle of it
Ok lets revice strange matter is a type of matter that when comes in contact with matter matter(i say so cause i dont know / just a 12 year old)it changes everything into one of its kind
We dont know much about anything
Plus you never know if strange matter particals ever collided with the steroids(i hope u ment astroids)we will never know! So yep feels like its a living organisms in space the touches dome thing and that something becomes one of its kind .. its also known as the virus of the universe
So death in form of strange matter is not yet confirmed

@jayvir jadeja That wasn't useful in any way. I've seen plenty of rough estimates, but nothing near the speed of light, and everything I've seen has indicated that there's great uncertainty on the speed of the expansion. If you have better information from a reliable source, I'd love to see it.
