8 hours ago · In 1974, Hawking predicted that black holes are not entirely black but emit small amounts of thermal radiation at a temperature ħc 3 /(8πGMk B); this effect has become known as Hawking radiation. By applying quantum field theory to a static black hole background, he determined that a black hole should emit particles that display a perfect black body spectrum .

[6] [17] [18] This operational definition of time, wherein one says that observing a certain number of repetitions of one or another standard cyclical event constitutes one standard unit, such as the second, is useful in the conduct of both advanced experiments and everyday affairs of life.

8 hours ago · Such as the late atheist Stephen Hawking’s scientific declaration—“Because there is a law such as gravity, the Universe can and will create itself out of nothing” [6] —which explains the natural (the universe), as absurdly as Frank Tipler’s electroweak quantum tunnelling explains the supernatural (Jesus walking on water).
