GR may be a classical theory, but in quantum mechanics time and space are conjugate to energy and momentum, so as far as measurement issues reversal of events in time between two reference frames would correspond to energy measurements which are positive in one frame becoming negative implying...
allen,
u can only make local measurements as you fall through a black hole, so before u hit the horizon, locally all the events happening in ur frame happen in the future in the 'local' frame in which the black hole is stationary. But this does not represent 'all' the universe, but just the...
sure schwarzchild metric is time reversal symmetric, but a co-ordinate becoming timelike does mean that in the particular frame of reference the co-ordinate would refer to time measured by a clock in that frame, so any chain of events 'would' have to progress in an increasing direction of time...
Hi guys
I had a question. We know that roles of space and time reverses inside a black hole. In the schwarzchild black hole for example r and t are interchanged into time and space respectively. this argument is used to say that because time moves in a single direction r can only decrease...
