Wow! Signal | We Caught a 72-Second Signal From Space, Then It Disappeared

Maybe we were just the cloud for a little bit.

Red Web
Wow! Signal | We Caught a 72-Second Signal From Space, Then It Disappeared

Yeah, yeah.

Man.

Okay, one other small theory has to do with the wildness of space.

Researchers have proposed that a standard faint radio burst, something from a celestial object, common radio burst kind of activity,

might have gone through the process known as gravitational lensing.

If you've ever seen the movie Interstellar, you'll see how wormholes or black holes bend the space around them.

And you can actually and this is how we've been able to see galaxies incredibly far away.

Red Web
Wow! Signal | We Caught a 72-Second Signal From Space, Then It Disappeared

Oh, my God, this is so hard to explain because it's so mind blowing.

But if if there's a galaxy between us and a further away galaxy, if it's just right, the light from the galaxy further away can bend around the closer galaxy

bend around it like a lens, collapse back in on the other side, and then come to us looking like it's magnified.

Red Web

So you can literally use the gravity, the mass of a black hole or a galaxy, and you can use that as a magnifying glass to look at and listen to things on the other side.

You following?

Basically, in this case, they're saying the radio waves were emitted by something normal.

Red Web
Wow! Signal | We Caught a 72-Second Signal From Space, Then It Disappeared

just a light burst, nothing super strong, but they happened to pass by something with an incredible mass could be a star, could be a black hole, could be another galaxy.

Red Web
Wow! Signal | We Caught a 72-Second Signal From Space, Then It Disappeared

And it perfectly came by rap like the radio waves bent around that mass and magnified.

Red Web
Wow! Signal | We Caught a 72-Second Signal From Space, Then It Disappeared

So that way, when it hit us, it looked like a uniquely strong radio signal, but actually it was just like an amped up normal signal.

Red Web
Wow! Signal | We Caught a 72-Second Signal From Space, Then It Disappeared

Yeah, yeah.

And especially once you get to relativity, once things start traveling near or at the speed of light, game over, man.

Red Web
Wow! Signal | We Caught a 72-Second Signal From Space, Then It Disappeared

I think when a photon... Okay, I don't want to speak out of turn because a photon moves at the speed of light and because of that, time essentially freezes.
