And that's pretty impressive.

But there are particles we've seen from space that are like 10 to the nine times more energetic, right?

So like a billion times more energy.

And that's amazing.

The universe has an accelerator that way, way outputs ours, right?

It puts ours to shame.

What fraction of the speed of light would those be?

These things are point... Oh, wow.

They are really redlining it.

Where are they coming from?

So some of them come from the centers of galaxies or from really big stars or other stuff.

But some of these things, we cannot explain it.

Like, there's nothing out there in the universe.

You ask an astrophysicist, like, give me a particle of this energy, how do you do it?

They're like, we don't know.

Start from a supernova, whizz it around a black hole.

Nobody knows how to get particles at this high energy, especially because the universe turns out to be opaque to these kinds of particles, meaning it likes to absorb them.

So you shoot a particle out at this high energy, it shouldn't go very far.

It interacts with the cosmic microwave background radiation and it loses its energy.

So not only is there something new out there that nobody understands, capable of making particles of super high energy, it's not very far away.
