And then it's like, no, I'm going to become a black hole.

Then it becomes a black hole.

So that's the second option.

The other thing is it becomes a black hole immediately.

They collide, blam, you've got a black hole.

There's no intermediary neutron star.

So those are the three things.

So then they thought about, well, how would light get emitted?

How does light get emitted from such a collision?

The light can be emitted immediately on contact.

Light would be emitted immediately.

Or the light could be generated within the neutron star collision, and then it takes a while to propagate to the surface, and then it's emitted.

Or the third option is that perhaps light is emitted immediately or not, but it hits the circumstellar debris that's around this collision.

And it gets redirected and absorbed and re-emitted, and that causes the delay.

So the bottom line from these scientists was that they determined that this collision from 2017 created a temporary neutron star, very briefly, that then became a black hole.

So that seems kind of like, yeah, that's the likely scenario.

But the light that was emitted, either it was emitted internally and it was delayed, or it was emitted immediately or internally and was delayed because of this circumstellar debris.

So that's what probably happened.

That could easily explain the 1.7 second delay.

So that's not too much of a mystery.
