What If... (Gravity and Black Holes)
What if the center of every planet is a filled up black hole? Earth's acceleration of gravity is 9.8 m/s, but as you get closer to the center it gets stronger. What if the center of the sun is a huge black hole that is filled up, and its gravity is strong enough to have all of these planets orbit around it.

How much mass can go into a black hole before it fills up? Thoughts?

It doesn't matter if singularities are the source of gravity.
It would change nothing.

Re: What If... (Gravity and Black Holes)
A black hole is a rip in the fabric of space, because it was so heavy it fell through and opened up a gateway to another place, can not be filled up with anything, it can expand though if enough matter goes into it

If the sun went supernova, we would all be blown away. The black hole that was left would begin to eat it's surroundings and continually grow to most likely consume our neighboring planets. As black holes expand, their mass increases, thereby increasing the gravitational pull on surrounding objects.

Re: What If... (Gravity and Black Holes)
a black hole would grow as long as it had matter to consume. there are theories that there is a size limit to black holes which is 10 billion solar masses, a point where a black hole ejects as much information as it consumes...

No our sun is to small to make it to a black hole stage, it would need to be manny times larger and then implode in on itself

Right, just making an example because it's the closest star to us. Our sun should turn into a dwarf.
