One professor in my Uni doesn't believe in Black Holes.

I don't know.
That's a very neat gif tho, thanks.

Look at me, now look at your ass, now back to me, what colour is that hole? A black colour, now look at it again now back to me, now back to me, how would you describe a hole that is black? Is your answer black hole? Good now look at your ass, now back to me, now back to your ass, do you believe in black holes now? Good. My work here is done. I will be in my lab now....

You shouldn't. Being a physical realist is stupid.

The fact that mass is a useful notion for humans to talk and calculate shit about the world around is doesn't mean mass "exists".
Fundamentally you have theories for smaller and smaller things, and some good approaches involve some field theories governed by some relatively simple dynamics equations with a few parameters and all the abstractions like mass are just summed up quantities, order parameters that have no bearing beyond the linguistic one. Same for black holes.

One professor doesn't believe in global warming

One professor doesn't believe in evolution

One guy doesn't believe our eyes are real

Actually another professor in the same Uni doesn't believe in Global Warming. I bet he posts here.

It isn't really that neat at all, everybody loses their mind because its gravitational in nature, but if it was electric you'd call it a lens and wouldn't give a rats ass.

Gravitomancers will be a thing in your lifetime.
They will relable their name to something shitty like Gravity Engineers.

Fml senpai.

>Black Holes

Wow, language. You mean African American holes, of course.

this, THIS! You are the first one I see on /sci that shares this point of view, the first one that knows the onthology of science. Thabk you, you made my day.

>doesnt mean mass exists

>he can't mathematically proove that math exists

>>8756556
They don't actually. The event horizon is not actually part of the black hole, just a visual consequence of its gravity. All the light is pulled toward the actual object itself, the singularity. Since all the light is there, it's actually infinitly bright and not black at all

Isn't science.

Mass doesn't exist

He's an idiot then. They have been observed pretty much directly.

They were predicted by mathematics; subsequently their effects on light and matter have allegedly been observed. Your question should be accompanied by an explanation or concept that justifies your abandonment of the consensus. Why shouldn't we believe?
