Question
The original concept of a dark star, or black hole, was that anything entering it (including light) would never leave. Then came Hawking's idea of black hole "evaporation." Now, it seems that black holes may do more than evaporate, they may regurgitate.
The "wormhole" idea dating back to Einstein and colleagues said that it is impossible to create a stable wormhole after the Big Bang. Now, string theory says it may be possible after all.
Putting gravity together with quantum physics may give us new ideas and eventually new technologies. Where do you see us headed - and do you want to go there?
Explanation / Answer
The theory is at best incomplete. According to Hawking,black holes might actually have a halo of 'soft hair' surrounding them, which are capable of storing information ,but that 'hair' is not actually hair,i.e, actually low-energy quantum excitations that carry with them a signature pattern of everything that's been swallowed up by the black hole, long after it evaporates.black holes release a tiny amount of radiation back into space. As it releases this radiation, the black hole actually loses mass, finally evaporating away entirely. The amount of radiation increases as the black hole loses mass. It’s actually possible that it could generate a final burst of X-rays and gamma rays as it disappears completely.
When the last black hole evaporates, all that will remain in the Universe are photons of radiation, and elementary particles that escaped capture by black holes. The temperature of the entire Universe will reach a final temperature just above absolute zero.
Dark energy may play some future role, continuing the expansion of the Universe, accelerating each of these elementary particles and photons away from each other until they’re effectively cut off from one another according to a study. No future gravity will bring them together again.Perhaps there will be another Big Bang someday. Or, the Universe is cyclical and the whole process will start up again or it won’t, and this bleak future of a cold, dead Universe is all that awaits us. also, Quantum gravity could now answer questions regarding the Big Bang.
Yaa.. i want to go there and try to find out the real truth.
