Re: What Does a Growing Black hole Mean?Posted by egibbs on May 15, 2002 at 06:20:27: In Reply to: Re: What Does a Growing Black hole Mean? posted by davidmac on May 15, 2002 at 04:41:04: However... Imagine two imaginary ants who live on the surface of the Event Horizon (yes, I know - there is no actual surface there, that's why the ants are imaginary) and measure the distance between themselves over the curved surface of the Event Horizon. As the hole accretes mass it's radius grows at a certain rate, which I believe will always be less than C. But the distance between any two points on the Event Horizon grows more quickly because surface area increases faster than radius. It is possible that the surface area of the EH could increase fast enough that two points on it move apart faster than C, even though the BH itself is only growing at a rate slower than C. This would almost certainly be the case as the BH was forming. I've always thought that this might be a good explanation for inflation. Of course, that would mean that our 3 spatial dimensions are actually embedded on the surface of a really big BH... Ed Gibbs
