Ok you guys have probably seen this question a lot but Im gonna go with it anyways.<br /><br />From what I understand, if an outside observer was to witness an astronaut falling into a black hole, relativity dictates that we would see him approach the black hole slower and slower until he ultimately "freezes" in our relative time due to time dilation. My question is, would we actually observe a frozen astronaut in space from our perspective (as in a photographic snapshot)? Doesn't the light become so redshifted that the astronaut's image would appear redder until ultimately fading away? And for the astronaut entering the black hole, would he experience going slower and slower? Curious isf it has effects on his body as well, heart beat etc.
