-------LYRICS---------
INTRO
Welcome to the end of the universe.
Please fasten your galactic seatbelts as we explore the
5 Most Likely Cosmic Apocalypses
A...poca...lyp...si?
Existential dread and Euphoria can be found
Here and Here
In the inconsiderate vastness of space
Enjoy the ride
BIG CRUNCH
Universal Gravity
Falling fruit from apple tree
Though it is the weakest force
It just might kill all of us
Andromeda galaxy
Hurling at amazing speeds
The Milky Way pulling close
Colliding in a brilliant burst
But if you didn’t know
This violent destruction has got nothing on
The Big Crunch
The Big Bang blew it all apart
Flying fast and flying far
But gravity in its infinite range
Could lead to a directional change
Collapsing in on itself
Surfaces of stars igniting, ouch!
Explosions tear through stellar space
Hot plasma in your face
It’s The Big Crunch
Where nothing can survive
Densities and temperatures beyond measure
We’re going to die
More intense than the Big Bang
And if gravity doesn’t win
The opposite will soon begin
HEAT DEATH
Oh it’s getting kinda cold
Which is weird for a thing called a heat death
But the entropy’s only increasing
It’s gonna be slow devastation
Cause it turns out the rate of expansion
Is way faster than we once imagined
Distance galaxies wander and fade away
Darkness grows as we float ever isolated
All thanks to the cosmological constant of dark energy
Heat death, it’s a really cold
Heat death, yeah we’re all alone
Energy gradients fade away
Particles of matter all decay
It’s a
Heat Death, the arrow of time is gone
Heat Death, one giant cold heat
BIG RIP
Of course if dark energy is not constant we get 'phantom energy'
Which means we have an accelerating expansion at an increasing rate
Give us the Big Rip
Where gravity can’t keep up
Stars and planets are pulled apart
Atomic forces no longer hold
Molecules break apart
Atoms break down
Everything explodes into infinity away from everything else
And the fabric of space is ripped apart
VACUUM DECAY
Ever heard of the Higgs Field?
We’re talking Bosons getting revealed
Giving mass to our particles
Writing tons of articles
Giving us stability
Well this field seeks the lowest energy state
Like a ball rolling down a hill can’t wait
But if a lower potential exists
Say goodbye to our constants
Physics falls apart and we get
Vacuum Decay
We’re in a false vacuum
A false vacuum
The best data suggests we’re in a false vacuum
Evaporation of a black hole
Could trigger change that’s out of control
Entering the true low vacuum state
And a bubble it will make
Spreading all across the universe
But it’s impossible to see this moment coming
At the speed of light it’s moving, you ain’t running
The final apocalyptic cascade
Nature fully rearranged
Incinerating everything it’s
Vacuum Decay
We’re in a false vacuum
A false vacuum
The best data suggests we’re in a false vacuum
Vacuum Decay
We’re in a false vacuum
A false vacuum
The best data suggests we’re in a false vacuum
BOUNCE
There’s something awry here
An error or two
Either gravity’s broken
Or another dimension’s leaked through
Cause it’s weakness, the force
It just doesn’t add up
What if instead of just ours there are more?
Universes out in spacetime galore
Influencing, softly dancing
Ready to bounce
Ready to bounce
Oh these parallel branes are expanding to start
But then fate as it goes just can’t keep them apart
We’re obliterated as the scalar fields swing
Into radiation and restart the Big Bang
So what’s the world without you?
It ends but then it cycles on through
The universe born again new
So tell me what’s the world without you?
If another one’s bouncing in soon
Now I know some of you might be saying
“Gosh Mitch! All these possible endings,
It’s got me scared, should I be worried?”
Awh, don’t worry
Most of these are predicted to happen in billions of years, if ever
And if that has you saying
“Billions? But that makes me feel so small and insignificant”
Well…that’s because you are.
So what’s the world without you?
It ends but then it cycles on through
The universe born again new
So tell me what’s the world without you?
If another one’s bouncing in soon

[@austinfreyrikrw6651]

Hahaha, did not expect a musical explanation of the physics theories to the end of the universe! Appreciate the efforts you guys put into this video ❤❤❤

[@ambertuck89]

Yeah makes our unpredictable deaths kinda easy to take in.

Okay so now I'm gonna have FALSE VACUUUM playing on repeat in my head for the next few weeks, thanks a lot

[@jettmthebluedragon]

Well the ironic thing about vaccum decay is ok the vacuum will de destroyed right ?😐well the irony is what CREATED the the vacuum to begin with ?😐

[@bouclesdor7984]

Hahaha I feel the same !

you mean VACUUM DECAY?

well i guess your brain energy got vacuumed away (i hate making puns)

This is absolutely fantastic. Can a KZbin video win an Emmy? Seriously. I'm asking.

[@mhawang8204]

It can win a Streamy Award

[@tedk0]

Yeah, Johnny Harris won an Emmy along with NY times for their "Blue States, You’re the Problem" video. Also Mitch can win a Grammy!

[@ReubsWalsh]

Or a Grammy!?

[@mastermantejas]

Yeah 😅

[@danielz1666]

No, a KZbin video cannot win an Emmy. Seriously. I'm answering.

[@mehlover]

I was afraid this was goodbye for good. So glad I was wrong. Love having a musical about the eventual goodbye to the universe lol. Y'all always floor me when you do something big as this! Also if science were musicals, I'd totally be into it

[@alexanderscozydesk]

I thought they are gonna explain why they don't want to make songs anymore!

[@Enderia2]

It would’ve been funny if they waited to upload this until April 1st

[@ielaypogi]

there is one more on acapella science

Am I the only one who hopes the Bounce happens since it means that alternate realities exist and life will always exist indefinitely.

[@joshuajohnson3713]

Same

[@bunfun.]

Me too because it’s the only ones that will allow life again I hope it’s a bounce happened what’s the other ones 7:22

[@drdotey2443]

Who says that life will exist in one of the universes. What if life dosent exist in one of the cykels, but then is there in another cykle.

[@Eville..]

The big crunch also allows for the renewal of the universe and thus a cycle that can restart the building of life.

[@kisa8930]

Heat death would allow us to exist for much longer though

A musical and cinematic masterpiece. I recently just listened to your podcast on perfectionism. If this was the music video you were referring to in it--the one you were holding back on releasing because you wanted to tweak things forever--then congrats on finally releasing it! I can't believe you've been holding this from us this whole time.

[@vero_sr_g800]

I hope this was fun making and filming because I enjoyed this very much. I hope a teacher out there shows it to their students when they are talking about space.

[@tbefilms]

MITCH. I knew you had musical chops. Of course I knew that already. But THANK YOU for dedicating so much time to making this. It was INCREDIBLE. Your voice is GORGEOUS and your beats are legit something I could picture all over the charts. Only unfortunate thing is I don't see the song on Spotify at the moment! I have found my new car ride jam. Maybe if I listen to it enough times I'll understand it...

[@aparajitabhattacharjee4686]

It's on Spotify now

[@GuadalupeMartinez-jy8do]

I was actually listening to this in the car😄

[@The_Everything_man]

Fun fact: the 'vacuum' of space isn't something that pulls you in, instead it's the absence of literally anything there.

[@B_Van_Glorious]

I clicked on this out of love for your work but wondering "what the hell are these guys gonna bring to the table that hasn't been talked about already a hundred-bleepin-times" And whoa buddy. You did not disappoint. This is why you got 10 un-frickin-believable million followers. Bravo.

I know Im 10 months late so im just reminding you of this song. But yes we need a full version of the big bounce. It had such a good vibe

[@hanni4442]

The first and second song and the end definitely give me Bo Burnham vibes, loved it.

[@manafestation]

As a musician, that was amazing, thank you. Something tells me you also had your mental universe expanded and were inspired after watching that one special a little while back that raised the bar on creative possibility that you just met with this wonderful gem of a video.

Today's Fact: In 1948, a man named Eugene Weidmann was executed by guillotine in France for a series of murders; he was the last person to be executed by guillotine in France, and years earlier, he had escaped from a Nazi concentration

[@Dextronaut1]

bit random but okay

[@paresseuxdesneiges]

Ok but it's wrong, quick internet research: (in french) De 1974 à 1981, sous la présidence de Valéry Giscard d’Estaing, les trois dernières exécutions capitales eurent lieu : Christian Ranucci, le 28 juillet 1976, à la prison des Baumettes de Marseille ; Jérôme Carrein, le 23 juin 1977, à la prison de Douai ; Hamida Djandoubi, le 10 septembre 1977, à la prison des Baumettes de Marseille.

2:51 Big Rip got the short end of the stick. That was deserved, we can agree Big Rip is the worst one.

[@LibbyTheVioletStickman]

I feel like Vacuum Decay is the worst, because of how unexpected it can be.

[@EnriqueLaberintico]

@@LibbyTheVioletStickman Big Rip is the worst because it's the only one that can't be followed by a new universe.

Bro the Big Rip is equal to Infinity getting vanished

I did like that it was given a creepy tune. Goes well with the fact that the potential for a new universe goes down the drain as spacetime is torn apart.

i like how it went from a calm song to a literal analog horror video at the transition from heat death to the big rip

[@caragottalife]

Ok WHAT ?? That was incredible. I’ve been following you guys for like 6 years now and listening to your podcast, and I think that’s the coolest thing I’ve seen produced by you yet.

The Big Crunch is my fav I’m trying to memorize it all

[@queen-lilyorjiako268]

I like how Heat Death doesn't end and just slowly turns into The Big Rip, it feels fitting considering how similar those apocalypses are.

[@cactusofdoom]

Sound off with your personal favorite scenario. Mine is the big rip because the way I conceptualize is like the universe pops like a balloon. So the big rip is literally the biggest possible r.i.p. and I find that very amusing.

[@littishishstudios8383]

6:33 asapscience out of context

[@TheUltimateEnderling]

Can we get full versions of Big Crunch and Heat Death? Those are my favorites, and I want heat death to be our universe's fate. Nice, slow and chilling. I even have vivid dreams where I go through the universe's heat death, but timelapsed and with time skips.
