Black Holes-mathematical singularity or physical reality???? Hi, I posted maybe a week ago and got some excellent feedback on experimental eveidence for GR. this post is intended to start debate, not as a question demanding an answer.... after reading around for some time and speaking to my lecturer on GR i have found out that Einstein didnt believe black holes existed as a physical phenomenna. from what i can make out he said something like them being a inconsistancy with the mathematics and not a physcial reality. If this is the case why are we seeing 'evidence' for black holes everywhere? how possible is it that 100% of the missing dark matter is black holes? how reliable are these claims that black holes have been detected? could they not be explained by other means? how can we even detect a black hole if all electromagentic radiation is lost within them and gravity waves have also not been detected yet? it all seems a little bizzare, especially when it does boils down to a mathematical singularity which has attempted to be explained by incorporating a physical phenomenna? and if Einstein didnt believe it, why should i????
