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.

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
@pseudorandomly 6 жыл бұрын
+Carlos "... 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.

@@FourOfClubs You sound like an expert. *sarcasm*. 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. You sound like a typical science denier, just saying "well no because this other thing" without any reasoning or logic, like when flat earthers try to say gravity is really bouncy force.

What a stupid comment. It took how many of the smartest people on the planet, how many decades and how much money to establish even an understanding of black holes in theory and you're going to blame some people for not being able to grasp the concept themselves? We scientifically don't know a fucking thing about black holes, only the effects they have on nature, yet you feel pretty big on yourself for simply accepting they exist, seemingly. The scientific method literally relies on people thinking what you have to say is wrong, so if you think those people saying something you disagree with perpetuates enough anger inside you to warrant hatred, you're as to be hated. Even if your last remarks were made in hyperbole.

I also have videos refuting the big bang myth.

Not really. A computer combined data from multiple radio telescopes and generated an image. Even if you accept the images as "photographs", they simply show areas of space with no light. 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 6 жыл бұрын

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.

And the explanations on the show weren't particularly convincing or even well demonstrated how gravity waves work. So I am really happy you uploaded this today to hopefully connect some dots.

Any amount of mass above a certain threshold always collapses into a sphere, even if not perfectly round (Like Earth) although with the mass and density of a black hole their roundness is basically perfect
@sahanavica.5574 6 жыл бұрын
Gravity pulls with equal force in all directions, so all objects that are significantly massive will be crushed and squeezed into a spherical shape by the gravitational forces holding it together.

some dude thats dead inside Physics always let us think outside the box, there are/will be many ways to know what's inside a black hole without delving into it (I don't know any, but I believe in this because if ordinary physics ideas are applied to black holes studies we would find something, like the existence of a duality between the inside of a black hole and something outside, the idea of correlation and entangled particles might be promising, quantum information might have answers, etc)

Rainbow Llamas except black holes pull because of gravity. They don't "suck". Sucking occurs when there is a difference in air pressure and nature tries to return things to equilibrium, which is impossible in the vacuum of space.

@Clementinewoollysock 6 жыл бұрын
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.

Its mostly 'dark matter' that holds the galaxy together, all the 'normal' (baryonic) matter in the galaxy (including Sagittarius A) add up to only a small fraction of the mass needed to stop the galaxy flying apart at the speed it rotates. 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.
