The End of the Universe

Welcome to the end of the universe

Please fasten your galactic seatbelts as we explore the

Five most likely cosmic apocalypses

Uh, apocalypsi?

Existential dread and euphoria can be found here and here

In the inconsiderate vastness of space, enjoy the ride

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 gonna die

More intense than the Big Bang

And if gravity doesn't win, the opposite will soon begin

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

Distant 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, it's slowly fading

Heat death, soak it up before it's gone

Heat death, yeah, entropy has

Heat death reached its maximum

Heat death, it's a really cold

Heat death, the arrow of time is gone

Heat death, one giant cold heat

Of course, if dark energy is not constant, we get phantom energy

Which means we have an accelerating expansion at an increasing rate

Giving 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

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

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?"

Aw, 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
