If white hole is the reverse of a black hole does it mean that inside the white hole time accelerates?
Strong candidates for black holes have been identified in the centre of many galaxies, and in supernova remnants; the general mechanisms that would lead to their formation and growth are well understood, and these conditions are thought to be fairly common throughout the universe."White holes" are a possible solution of Einstein's field equations. For now, white holes remain a purely hypothetical construct, with no candidates identified in the universe today, and no established mechanism which could create and maintain them.There are suggestions that Hawking radiation from a black hole could represent a white hole, or that the Big Bang may represent a temporary white hole. Quote from: DIf white hole is the reverse of a black hole does it mean that inside the white hole time accelerates?According to Einstein, time slows down near a concentrated mass (as measured by a distant observer). So time will be slower near a black hole (or, more subtly, near the surface of the Earth).My understanding of the theory of white holes is that they are a concentrated mass. So my guess is that time will also slow down in the vicinity of a (hypothetical) white hole.
It is highly unlikely that gravity is the force that would drive a white hole. More likely a critical density is reached within the confines of a black hole where the electromagnetic forces overcome gravitation for some as yet unknown reason. It could be an imbalance in the distribution of quark charge. This repulsive effect would still be operating under the influence of extreme time dilation. In the frame of reference of the white hole this would be undetectable as proper time would be unaffected. It would seem to a remote observer to take forever for the expansion whereas from the white hole frame it could appear that the outward motion approaches light speed.
