Three ways the universe could end - Venus Keus

Our universe started with the Big Bang, but how will it end? Explore cosmologists’ three possible scenarios: the Big Crunch, the Big Freeze and the Big Rip.

--

We know about our universe’s past: the Big Bang theory predicts that all matter, time and space began about 14 billion years ago. And we know about the present: scientists’ observations of galaxies tell us that the universe is expanding at an accelerated rate. But what about the future? Do we know how our universe is going to end? Venus Keus explores cosmologists’ three possible scenarios.

I love how she's so positive and cheerful about how the universe is just gonna die

[rodi]

Big crunch is the most ideal outcome imo, as bittersweet as it is. It's the only one that doesn't result in life ceasing forever.

[Chris-pclk]

Big Freeze has always been most logical way to end it, but my personal favorite is the Big Crunch. I feel like it would be too much of a waste for everything to be erased forever.

The Big Crunch: exists
The Big Bang: where did that bring you? Back to me

[JohnCena]

I like the big crunsh/bounce theory.
To think that the universe will start all over again and will not just end as if it never existed is kind of soothing.
Maybe even history will repeat and you can see your beloved ones again. I know that's very optimistic, but it's worth a thought imo.

I've got chills while watching this. Back when I was in 4th grade, our science teacher accidentally discussed the big freeze. I used to have a really good imagination and I said what if the big bang is just a "reset" button and it was a remnant of a previous universe and that we're just stuck in a never ending loop. So now I know what that theory is called after watching this

[TommoCarroll]

Yes! New Ted-Ed video! I needed some positive vibes! Oh...wait... 😫

The big crunch/bounce makes the most sense to me. Everything we observe is a cycle. It seems the natural order is to repeat itself. The water cycle, the life cycle, moons cycle planets, planets cycle suns, suns cycle galaxies, etc.... We, as humans, only tend to think of things as a straight line, a beginning and an end, because that's our perspective of life. We are born and we die. Some things end, sure, but the laws of the universe certainly lean more towards cycles than ends.

My parents made a theory for me too




The Big Failure

[SleepNeed]

It's incredible to me that we as humans are even able to come up with a theory about the "death" of the universe. Always fun to learn something new, even if it's our universe's ultimate fate.

[alanf.cavalcante]

Remember of my self... a 9 year old in bed at night, paralised in fear when realised that the concept of death could extend it self to worlds, stars, galaxies and matter when given the right ammount of time, even without knowlege of such theories... that was terrifying.

My brain sucker-punched it self into meltdown trying to grasp infinity.

[Hydratz]

Whats the worse song you've ever heard?

[JaceTimes]

What if the big crunch has been happening since forever and we have been living multiple lifetimes repeating what we have been doing forever

[TheGaminggk]

Im a condensed matter physics student. But in my opinion, seeing how everything is oscillating, I believe in the Big crunch or the big bounce. Everything will just repeat itself continuously forever and ever. Because it there is a beginning, then there's an end which again just means a beginning.

[ferronzomeren]

A rubber band is a bad metaphor, because the force in a rubber band increases as the distance increases, but gravity does the opposite. You could see the animator struggeling at 1:20 with visualizing this metaphor because it is incorrect. XD

[SanAndreasFool]

I’d prefer the big crunch. Its the one to me where life has the greatest chance to start again. It gives me somewhat a peace of mind. After all, life must continue at all cost.

4th way galaxies could end : the big hug !

[scienceogram]

Thanks Ted-Ed!! Now i can be depressed on things that might happen billions of years later😫😫

The Big Freeze is taking a computer apart, section by section, until nothing has any function or use. You also forgot how to build computers.
The Big Rip is taking a hammer and smashing the device into dust. No use left.
The Big Crunch is refining every single material making up the old computer. Theoretically you can turn it into a new one.

This video made me feel insignificant and question my existence.
