Relativity Question

[daveman]

Recently scientists noted that Sag A, the black hole at the center of Milky Way, flared up 75 times brighter and thought it might relate to a massive dust cloud that came close to it in 2014.

Relativity state that time slows as you approach a black hole and stop altogether as you fall into it.

If this gas fell into the black hole near light speed, time would have slowed to a near stop. How can a gas cloud that approached in 2014 be the cause of the brightness, wouldn't it now take this light many thousands of "extra years" (compared to our POV) to reach us? I understand what we saw in 2014 actually happened 25,000 years ago, thats not the point

Hello, how is a black hole bright

The light is created by matter being compressed NEAR the black hole, but before it actually enters the black hole.


I'm pretty sure much more light is actually created when the matter finally HITS the black hole, but that light, yes, would not escape.

The matter isn't compressed -- it's being torn apart. The gravity differential becomes so great that even on the atomic scale, the side of an atom nearer to the singularity is pulled far harder than the side opposite...so hard, the nuclear bonds are broken. Each atom being ripped apart releases a burst of X-rays.

That's not accurate. While that may certainly be happening inside the event horizon, closer to the black hole, the gradient is not that strong outside the event horizon. And we could never observe xrays emitted in this manner, as they all end up in the black hole and never escape the event horizon from within it.

What happens to gas near a black hole is that it loses angular momentum due to magnetic fields and friction, and that energy is converted to thermal energy. The gas then heats up so much that it emits xrays.

Depends on the mass of the black hole.

The point at which tidal forces destroy an object or kill a person will depend on the black hole's size. For a supermassive black hole such as those found at a galaxy's center, this point lies within the event horizon so an astronaut may cross the event horizon without noticing any squashing and pulling, although it remains only a matter of time, as once inside an event horizon, falling towards the center is inevitable. For small black holes whose Schwarzchild radius is much closer to the singularity, the tidal forces would kill even before the astronaut reaches the event horizon. For example, for a black hole of 10 solar masses a rod breaks at a distance of 320 km, well outside the Schwarzchild radius of 30 km. For a supermassive black hole of 10,000 solar masses, it will break at a distance of 3200 km, well inside the Schwarzchild radius of 30,000 km.

False. We have, indeed, measured the gravity of a black hole, thus determining its mass.

Wrong again. As always.

Sorry, didn't mean to bend your mind with a lot of sci-fi. The above was taken from and based on the work and research of Stephen Hawking.

Nothing in Hawkings books is fact, I hate to break it to you, Hawking also admitted to being a fuckup

Stephen Hawking admits the biggest blunder of his scientific career -

The cosmologist Stephen Hawking has described the biggest blunder of his scientific career – his early belief that everything swallowed up by a black hole must be lost forever.

Professor Hawking said that there is one thing that does in fact escape from black holes – radiation. He has previously said that his discovery of what is now known as Hawking radiation was one of his proudest achievements.

Hawking was a con artist who fooled you blind

Suppose there was a black hole 1 light year from us. Our telescopes can watch it fairly clearly and accurately. We watch a Volkswagen beetle fall into the event horizon. The VW Beetle has a telescope that can see us here on Earth. To us, would it look like it only took a minute, while to the VW, which is experiencing a radical slowing of time it took thousands of years? Would the VW watch thousands of Earth years pass in what is only 1 minute to us?

Actually, the VW Beetle would experience no time problem. For them, falling into the horizon, if they sensed it at all, would happen quite normally. But we would never see it. For us, they would slow down more and more until finally, they appeared to sit for an infinity at the horizon, while their looking back at Earth would see time speed up for us, until centuries passed by here from their POV in the blink of an eye.

It's the other way around. The driver of the VW would not even notice they crossed the event horizon, and it would do so in an instant. To us, the VW would take literally forever to cross the event horizon.
