Light is energy is mass is gravity?
Quote: Renegade Carpark @ September 7 2009, 12:06 AM BSTI too have pondered the 'speed of gravity', particularly with regards to black holes and their immense gravitational pulls that can suck in light. Does matter entering a black hole get any where near the speed of light as gravity sucks it in? And how does something become infinitely dense? (I mean aside from watching Coming of Age?)
You have tasty thoughts.
Could a black hole absorb light and everything else and change it into dark matter?
