I pretty much understand how stars of a certain size/mass become a blackhole ..BUT i'm puzzled.
Surely the light from the star as it colapses , will , to an observer( at some distance ) ,remain put , at least for millions of years. As, at the event horizon time comes to practical standstill. I'm thinking of those last remaining photons that just have enough legs to get away. I'm even thinking maybe they don't ever get away , so a black hole in effect should look like a small dim star?
your thoughts please
thx
