    Black holes are a tricky object because, as they let almost nothing escape their horizon, you can’t easily observe them. You can only observe the impact on their surroundings

    There are 3 lines of evidence for existence of black holes

    1.A blaze of X-rays

    Matter that comes too close to a black hole (gas, dust, stars) is drawn towards the hole. As the matter spirals in towards the edge of the hole, it heats up, reaching millions degrees before plunging into the black hole. When gas is this hot, it glows in X-ray light, and can be seen by an X-ray space telescope such as Chandra. This glowing disc of gas is a fingerprint for the presence of a black hole.



    2.Super-powerful jets of matter

    Giant jets of matter (the most powerful beams in the universe) are observed to shoot out from a galaxy's core at almost the speed of light. The only known source powerful enough to produce such jets, is a giant spinning black hole. The jets seem to originate from just outside the black hole's edge ("horizon"), where temperatures and magnetic fields are at their most intense. How the black hole creates these jets is not known.



    3.Rapidly moving stars

    The gravitational field of a black hole tugs on the stars in its vicinity. A super-massive black hole will make whole swarms of stars whip around as they fall under its influence. By following the motions of the orbiting stars, astronomers can deduce the location, and size, of the central black hole they cannot see.

    Experts have, for example, theorized that supermassive black holes might be at the center of galaxies.
    UCLA’s Galactic Center Group has done an animation of inner galactic stars along the years:



    You can see a clear pattern of stars revolving around a massive object at the center. You can also see some of them gain an incredible amount of speed as they get closer and closer to the center.

    This is theorized to be a Black hole.

    From these lines of evidence astronomers are convinced that black holes are real.

    More than a dozen black holes have already been discovered in the Milky Way galaxy (out of more than a million black holes estimated to exist there) And a giant black hole, heavier than millions of stars, has been discovered at the center of our Milky Way galaxy. The same picture appears to hold for other galaxies in the universe: black holes scattered through the galaxies, with a giant black hole at their center.

    Some people speculated that at the bottom of a Black Hole would be a White Hole that leads into another reality or another region of space and time. Stephen Hawking says so.





    That is the basis of a concept called ‘Wormhole’ speculating that different sections of space-time can be interconnected by a single tunnel that matters can travel through it.

    Wormhole has long since been a subject of heated debate between scientists and if it actually existed ?

    I mean if it was possible to travel instantaneously through space in the blink of an eye or maybe even travel back and forth in time ?

    I can't even begin to imagine how the white supremacists would try and weaponise that

    That’s all we know about it, as we’ve never been into a Black Hole and we probably won’t anytime soon and even if there was the technology to get to a black hole and let's say you wasn't ripped apart, once you get past the event horizon (basically the point of no return) you can not come back, you may think “Well send a probe then so it can send radio signals back to us” well a black hole is so strong that light can't even escape it once it gets to close. So the radio signals wouldn't come out.

    End of the day Supermassive black holes play a crucial role in the formation of large spiral galaxies like our Milky Way Galaxy. So the chances are that we would not exist it were not thanks to the supermassive one at the heart of our own galaxy.

    Is there anything you can talk about without mentioning white supremacy?

    Unlike you, white supremacists would be intelligent enough to understand that you don't fuck around with black holes. You can't weaponize black holes; wormholes, maybe, and no, wormholes are not naturally occurring phenomenon; you have to generate them using exotic matter, which scientists are not capable as of right now, and probably never will be.

    No, he's too dumb for that.

    He didn't make that post; he simply copy/pasted it (partially at least, probably from other websites as well) from a Quora post without giving credit or at least using the quote tags:

    https://www.quora.com/Do-black-holes...harlie-Auzet-1

    The notion that @Paul Essien understands anything about black holes to begin with, is just loltastic.

    Paul, start writing your own posts from now on or at least use the quote tags when you're quoting something. Copy/pasting walls of texts just to sneak in a one-liner about white supremacism in a non-political topic like astronomy, is lazy posting and trolling. Keep that up and you won't be around here much longer. Consider this a fair warning.

    There is no such thing as "proof" of anything. There is only evidence. There is evidence of black holes, although black holes can't be directly observed. I would say they are real. Astronomers study this type of thing with their instruments, and in their opinions, black holes are real.

    The word believe is interesting. If you saw an elephant, there would just be evidence it exists. Nothing could actually be proved (it could all just be a dream).

    Black holes can be observed. It's true that they don't omit light like stars, but it's basically a large black dot that bends light, and occasionally sucks in stars (which has been observed, when this happens). So black holes are totally real and observable, aka evidence/proof. They're also theoretically required, for the constellation of galaxies, because it's due to the heavy gravity of supermassive black holes, that keep the stars in our galaxies together as a cluster. Moreover, black holes are just two or more stars, that either collapsed with each other, or due to the nebula from several supernovae, that eventually formed into a black hole rather than a new metal rich star. Black holes are basically a lot of matter that transformed into a black hole instead of an ordinary star. If you poured enough water on the sun, you wouldn't extinguish it, but rather, you'd increase its mass so much that it eventually would turn into a black hole. Mass = gravity, and enough gravity = black hole.

    So now you know.

    The evidence points in that direction so scientists are pretty confident that black holes exist yes.
