Hace 1 día · Weird physics at the edges of black holes may help resolve lingering 'Hubble trouble'. Different parts of the universe could have different rates of expansion, potentially explaining the ...
13 de jun. de 2024 · Nothing is darker than a black hole. A black hole is an area of such immense gravity that nothing—not even light—can escape from it. Black holes form at the end of some stars’ lives. The energy that held the star together disappears and it collapses in on itself producing a magnificent explosion. Here’s where things get crazy.
Hace 2 días · A black hole with the mass of a car would have a diameter of about 10 −24 m and take a nanosecond to evaporate, during which time it would briefly have a luminosity of more than 200 times that of the Sun. Lower-mass black holes are expected to evaporate even faster; for example, a black hole of mass 1 TeV/c 2 would take less than 10 −88 seconds to evaporate completely.
29 de jun. de 2024 · black hole. Artist's rendering of matter swirling around a black hole. black hole, cosmic body of extremely intense gravity from which nothing, not even light, can escape. A black hole can be formed by the death of a massive star. When such a star has exhausted the internal thermonuclear fuels in its core at the end of its life, the core ...

Hace 6 días · It would need to be some 20 times more massive to turn into a black hole at the end of its life. So, we don’t have to worry about a black hole ripping apart our planet either.
