    This video is about the astronomical amount of astronomical evidence for black holes, ranging from x-ray binaries with accretion disks, supermassive infrared-radiating galactic nuclei black holes, orbital characteristics of high mass binaries, and direct gravitational wave detection of inspiraling merging black hole binaries with LIGO. Yes, they're real.

    The black hole turns to the star and says, "Sir, I don't think you understand the gravity of this situation."

    Reading the comments, no the X-rays "emitted" from black holes has nothing to do with Hawking Radiation. The X-rays come from the super heated accretion disks of dust that surround the black hole, heating up as it collides with other dust as super high speeds and radiating light.

      well actually we only have proves that objects that look and behave like blackholes exist and the stronger of them comes from LIGO a short time ago so maybe your prof was actually in right if he intended to highlight the fact that we weren't sure about them. Moreover blackholes are still pretty new in physics from the experimental side so if your teacher studied let's say about 50 years ago chance are they were actually still debatable object and he could have lose passion in physics from back then and thus he still think about them in this way

      "... there was no proof of the existence of black holes ..."
      The evidence we have for the existence of black holes, nicely laid out in this video, is, in the end, all circumstantial thus far. It amounts to "we don't know what else it could possibly be, but we do know that black holes would behave in the manner we observe". So from the narrow point of view of requiring absolute proof, your teacher was correct. However, the evidence is pretty overwhelming at this point; we've long since passed the standard of "proof by preponderance of the evidence".
      Sometime this year (2018), the Event Horizon Telescope project should produce a direct radio image of the event horizon of Sagittarius A*. If it produces the expected result, it will be even harder for critics to maintain that black holes don't (or may not) exist.

It's clearly not because it's always focused around large masses, such as the sun, large galaxies, clusters of galaxies, and allows us to see either objects we know are behind them or duplicates of objects, or one object that's wrapped around the massive object. If it was just in the atmosphere, then please explain why this is the case and why we don't see this literally everywhere we look in the atmosphere and please do explain how in the heck the solar atmosphere could cause lensing.

      If you define black hole as an area of space we can't see and don't understand then they are real. If you define them as supermassive impossibly dense objects that make all our orbital calculations work then they are theoretical.

      You use the color of the star: the color of a star is simply related to how much light is being emitted. Since light is emitted in all directions equally if you step back from the source less light reaches you (like making a goal from further became harder) so you look at the color and measure how much light has reached you and you extract the distance

    • @rednidedni3875
      @rednidedni3875 Před 6 lety

      The size of the Star tells You what color it should have, then You calculate how redshifted the light is. Combine the two and You get the distance.

    • @rednidedni3875
      @rednidedni3875 Před 6 lety

      Yeah, that'd be one way to find out. The other is redshifting... let me explain:
      So you know that the universe is expanding, right? It's expanding everywhere at once.
      Imagine a light wave flying at us from a distant star. As its flying, the universe is still expanding - slowly stretching the light wave out. Having a longer wavelength means the light is more red.
      From the mass of a star we can't only conclude how bright it is, but also what color its light should be. We check how much lower the wavelength is than what it should be and we can calculate how far away that star must have been.

      @Clementinewoollysock Před 6 lety

      Actually they might suck depending on the theory explaining them. Differences in air pressure suck because statistical entropic progression creates a force of suction. Suction is not a fundamental force, it simply emerges due to entropy. Similarly there is a theory for entropic gravity that states that gravity is the result of entropic decay of quantum entanglement on the surfaces of an evolving de-Sitter space. If this is correct, gravity would be the exact same type of emergent force as suction.

Stars in the galaxy do not orbit a central point like planets in the solar system orbit the sun. Stars on the edge of the galactic disk move at about the same speed as those near the centre. This is because of 'dark matter', whatever the fuck that is.

      It's not just theoretical, actual observed supermassive black holes have had their masses estimated and that's where the numbers come from. Of course it's not a direct mass measurement, but nothing really is.

      Henrique Aroeira, No. 0.75x means it's slower, not faster

      +Mark Neu but if it's slower, it takes more time
