Each ball symbolizes one of 100,000 galaxies

towards a mysterious point in our universe

We can't see exactly what is pulling us there,

you can see that if you have 100,000 galaxies

of those galaxies would have a black hole

So what can we expect to happen when nearly

100,000 black holes merge with one another?

let's get to know these 100,000 galaxies a little better.

belongs to a group of a few dozen galaxies called the Local Group.

Just like the Sun's gravity pulls the Earth toward it,

our Galaxy is pulled towards the other galaxies in our Local Group.

Our Local Group belongs to an even bigger collection of galaxies

and that supercluster belongs to an even larger supercluster,

The one thing all these clusters have in common is that they're

all being pulled towards one specific spot,

coupled with all the gas and dust that surrounds it,

has made it virtually invisible ever since its discovery

we can now see behind this cloud of gas and dust,

is really just another supercluster named the Norma Supercluster.

Norma has the mass of about 1,000 trillion suns,

which might explain why it's so attractive to these 100,000 galaxies.

So now we know where our Galaxy is heading,

and why we're heading there. But what could happen along the way?

with another of the 100,000 galaxies heading that way,

the most likely one being our closest neighbor, Andromeda.

If these two spiral galaxies collided, they would merge into one new elliptical galaxy.

During the collision, vast clouds of hydrogen would become compressed,

This would result in the premature aging of the “new” galaxy as it used up its fuel.

but that's because the black holes in the center of these galaxies haven't collided yet.

it will release energy equivalent to 3 times the mass of our Sun within a matter of seconds.

That would be enough power to create a disturbance in the space-time continuum.

And that's just two black holes colliding.

If all the black holes of the 100,000 galaxies

drifting towards the Great Attractor merged together,

it would release more energy than we could ever imagine.

But luckily we won't have to worry about that,

because these galaxies will probably never arrive at the same spot and collide.

You see, the Great Attractor is also being pulled

deeper into space by other massive clusters.

And these 100,000 galaxies are also constantly drifting apart,

and that expansion will be stronger than even the Great Attractor's pull.

What will eventually happen is that Laniakea itself will come apart,

and all the galaxies within this supercluster will start to drift even further apart.

no humanity-destroying event to end this episode.

Just a bunch of galaxies drifting off into the abyss.

Well, that's a story for another WHAT IF.
