  1. Black holes banish evil souls and bad luck that are in the form of star dust, in 30 years the skies will be crystal clear and we will be able to see farther into space and see more stars not less.

  2. For selling : Massive property in a massive black hole. Best view in the galaxy. No time constrain problems. Live forever without seen or being seeing by nobody or nothing than yourself. Don't wait for tomorrow or yesterday don't matter, buy it NOW. Call our telephones NOW and ask for Galaxy Administrator.

  3. I don't think there is a link between the mass of the central super massive black hole and the mass of the surrounding galaxy (which you actually do say a bit later on, just thought I'd stress the point)
    Also our Super Massive Black Hole may have gone through a period of rapid 'feeding' and thus gone through a Quasar era

  4. When you say the Super Massive Black Hole at the centre of the Milky-way, periodically emits bursts of electro-magnetic radiation, could you make it clear that the radiation has not come from within the Black Hole, this radiation has come from the accretion disk that forms around the Black Hole when matter is falling into the Black Hole.

  5. Photographing the Super Massive Black Hole at the centre of the Milky-way, is equivalent to photographing an object 1cm across at a distance of 28,000 km (approximately). Pretty amazing!

  6. Breaking news: NASA just took a picture of Sagittarius A*. Looks pretty cool, like that first black hole pic a couple years back, just a bit more, for lack of better words…refined. There’s more of a visible white ring around it this time. Idk, I think it looks pretty cool.

  7. When did we change the definition of a Black hole? By mere definition, a body cannot permanently orbit a black hole and must eventually be pulled to the center of the black hole. This naturally means that the radius of orbitals will decrease over time as some of the infrared traces have shown for the Sag A* cluster/constellation. If the orbiting body is not pulled in and destroyed, then the phenomena being observed IS NOT a black hole but a system or galaxy (much like the planets of the solar system orbit the sun with various shaped orbitals but never on a path to its center (spiral).

  8. I'm no physicist but i like to think that hyper massive stars in the first few millions of years of the universe collapsed as the laws of physics became more recognizable to the present, less super hot, universe. Leaving these massive, gravitationally devastating points in space whose effects are unfathomably massive. Unable to be seperated by the expansion of the universe.

    Maybe if we peer further and further back in time through Webb we will know the truth in our lifetimes!

    Feel free to tell me why im wrong im really curious what other peoples guesses are!

  9. I am no theoretical physicist, but I do have a theory about what black holes are. Physics seems to break down and not work the same in and near black holes, and time and space are all kinds of messed up. There is a lot about black holes that doesn't make sense, or add up, and much is unexplained. So, when the universe was created and particles were being formed, all the subatomic particles settled into their lowest energy state and are stable, except the Higgs boson. The Higgs boson assigns mass to all the particles, and without it, the universe as we know it would not exist. Particles would interact completely differently, if at all, and physics and chemistry would be completely different. The Higgs field settled into a "valley" and requires some energy to jump out and drop to a lower energy state. If that happens, it would be known as vacuum decay, or a true vacuum. What if black holes are a collapsed Higgs boson field? The Higgs field is stable for now, but what if the massive gravity and energy of a black hole could cause the Higgs field to collapse? Some scientists say that it would continue collapsing and spread out a the speed of light and destroy everything in it's path, but I don't believe that is true. Just like "strange matter" that destroys anything it touches. There is no evidence for this happening. What if Higgs fields can collapse locally, and in many different places? And what if a collapsed Higgs field requires more energy to grow and spread? We know black holes grow when they swallow up more mass, and there is a clear boundary of no return with black holes. This theory could explain a lot about the mysteries of black holes. Obviously, this is purely theoretical, and I'm sure there are problems with this theory. But many theories have problems, and change and evolve over the years. I just figured this was an interesting though I had.

  10. 👎 for ignorant stipulation keep in mind if you tell somebody something and you don't have proof for what you're saying you have made yourself a liar if you didn't know before you definitely know now you can't say you weren't told

  11. It is bafflingly astounding the things people will believe without a stitch of proof….. I mean no proof in any way shape or form just some Theory some guy said and people will believe it like they believe who their mommies and daddies are lol but at the same time maybe they don't actually believe it maybe they just think it's an interesting Theory…. at least I hope they will have enough sense to know better ……remember….if you don't know something….. you don't know something.
