This is what I read today:

Two black holes met and created something never seen before.

Here's the #paradox:

Black holes don't allow light to leave their #infinite #gravity.
The #event_horizon's #particle "#reflection" seem to be too far and too few in between to produce sufficient #visibility...

So what IS IT that makes us see #black_holes?

@Fliptease

From what I understand, compressed matter being swallowed by the event horizon create X-rays that escape it.

This is what allows us to detect black holes, that and gravitational waves.

I am not a physicist - don't quote me on this one.

@ParadeGrotesque
x rays, and all other rays are on spectrum.. the area of light we CAN'T SEE.
So I'm back to where I started from.

Thanks for the.reply🌷

@Fliptease

We cannot see X rays, but we can measure them.

How do you think an X ray machine work? πŸ˜‰

@ParadeGrotesque

Scalability and measurement hold for sub-relativity.

Measurements are accurate, and we can r&r devices based on such readings... until we approach relativity.
