For example a black hole is stable. As in
Ts=Tu
then what would be the uses of the BLACKHOLE.
Would it have any such use ?

Garth said:the tidal forces of the gravitational field approaching a Black Hole (BH) event horizon are so severe that you are much more likely to suffer from
Garth said:the accretion disc surrounding it is likely to be so luminous in the very high energy range of the electromagnetic spectrum (gamma rays and x-rays) that it would still be a very dangerous place to be.
Garth said:If you traveled through the event horizon there would be no guarantee that you would go anywhere beyond the 'singularity' at the centre.
Garth said:Some of the largest BHs, at the centre of quasars are very bright indeed
Garth said:Whether rotating or not, or whether it has an accretion disc or not I would still advise keeping clear of them!
PeterDonis said:Yes, but the BH that Kip Thorne used for the movie was a lot larger even than those--well over a trillion solar masses, IIRC. He was not trying to claim that such a BH actually exists; it's a movie, after all.
Garth said:I thought Gargantua was meant to be smaller than that, 108M⊙, whereas the one at z=6.30 is ~1.2 × 1010M⊙.
A black hole is a region in space where the gravitational pull is so strong that nothing, not even light, can escape from it. This happens when a huge star dies and collapses in on itself, creating a point of infinite density called a singularity.
One potential use for black holes is as a source of energy. It is theorized that the intense gravitational pull of a black hole could be harnessed to generate power. Another potential use is for space travel. Black holes could potentially be used as a shortcut through space, allowing for faster travel between distant points.
While there are theories that suggest black holes could be used for time travel, it is currently not possible to confirm or test these ideas. The extreme conditions within a black hole make it difficult to study, and the technology required for time travel is far beyond our current capabilities.
The biggest danger of exploring black holes is the extreme gravitational pull, which could tear apart anything that gets too close. The intense radiation and high temperatures near a black hole would also make it difficult for humans to survive. Additionally, the unknown effects of entering a black hole could pose significant risks.
Scientists study black holes using a variety of methods, including observing their effects on nearby stars and gases, analyzing their gravitational waves, and examining the radiation emitted by matter falling into a black hole. They also use computer simulations to better understand the behavior and properties of black holes.
