Black Holes: Creation & Consumption of Galaxies.

When you add mass to the thing, its radius will increase. Asuming density goes as mass over radius to the 3rd power (which is not true for black holes, but it serves the point) as it does in any other sphere, the radius will increased by the cube root of the increase in mass. What does this mean? If the black hole becaumes 27 times more massive, its radius will only become 3 times larger. As black holes are usually pretty massive and stars are pretty small, the increase doesnt amount to much.

'Only' theory? Theory is the end-goal of all science!

What I want to know.. Is where everything goes whenever it pulls in the light, gas, stars, and galaxies.. Weird..

This is only theory. Until someone actually get's close enough to really study one, no one really knows what they really are. Though the gravity is there, what really causes this is still really a mystery.

Ok. A Black hole has huge gravitational pull. If this pulls mass of other stars and various space substances, the black hole itself, must have its own mass. But if it is constantly pulling in mass, shouldent the black hole be expanding extremelly quickly? I know it must be compressing the mass so much, but it has to expand at some point. It cant stay the same size forever, because that would require huge amounts of gravitational pull, but if it had that much, it would just compress its self.

Yea its a mathematical explanation for the extreme density known as a blackhole.

Let me guess,you pretend to be a John Nash?Because you took this phrase from beautiful mind...

What? I have never seen that movie douchebag....I did see gladiator though...

well although I agree, All we have is a mathematical explanation for the anomaly know as the black hole.

LOL thanks my grandkids will get a kick out of that.
