1. Socratica, you are truly an inspiration. Your videos are intelligent, well documented, very well narrated and interesting. You are a great inspiration to young generations and I hope you continue to share with us the valuable knowledge of the nature of things. And, BTW, ...you're hot!
2. Mm what is the temperature. Of a black. Hole...
3. i really love the way she explains it.................
4. Did anyone kbow there's 14 black holes and stars are bigger than the Sun
5. A lot of lies to debunk!
   1. First lie in this video. Matter DO NOT bend time. Time IS matter! Fourth dimension powered by energy and split to waves know as particles.
   2. Gravity affect on space making gravity well!
   3. Stars ALWAYS orbiting around Black Holes!
   4. Black Holes warping space. That warp space is know as
   ergosphere that contain part of hole power.
   5. THERE IS NO "INSIDE" on Black Hole. This thing is FULL!
   It can't contain more mass so Black Hole radius RISE with mass and it's constant!
   6. Singularity have Schwarzschild radius! Mathematic FAIL aganist Black Hole!
6. Why is time freezing or slowing in the event horizonal
7. her beauty is hypnotic!
8. Eu gostaria muito que seus videos fossem legendados e portugues. Será que não teria como?
9. Amazing Video !!!!!!!!!!!!!!!!!!!!!!!!!!
10. "O universo e uma teia de aranha construída pelos buracos negros ."Alexandre
11. These videos are awesome.
12. Why does a black hole spin. It has to spin in order to do its job. As a black hole spins it builds up a ''skin'' around itself by centrifugal force. Only dense matter critical to the galaxy will be able to penetrate this skin. It would nor accept light matter like a spaceship etc. If a black hole was stationary or moved very slow it would loose its skin and the whole galaxy would be swallowed up. Who made the black hole spin. The powers that be did.
13. Very good video 😉
14. i have a question to ask imagine when three blackholes collides with one another what will happen and how much years does it take to stop this colliding
15. Amazing guys, definitely i love this channel :)
16. If a black hole was not at the centre if a Galaxy, the galaxy might explode. Because matter would be compressed to such an extent at the centre that the space inside the atoms would be compressed so much that the nucleus would rub together and split open. Than explode like a ginormous atom bomb. The black hole is a safety device to stop this happening. Like a safety fuse it won't let this happen. It's like a different dimension than the space around it. It seems to suck everything into it, even the fabric of space itself. We know very little about this type of science. I was created and somehow put there. In the Big Bang there was probably no safety device like this and it exploded.
    Basically the black hole is there to stop the galaxy reaching a critical mass. To control the gravitational fields and to regulate the speeds of the very atoms of the galaxy which it controls. To suck in material that is pertaining to be a critical mass. Neutralising the mass. It is one piece of brilliant engineering science to solve this problem. About the Big Bang. I don't think it was a single mass that exploded. That would not make sense at all.
    It was more like a percentage of the universe when say the galaxy's were closer together.
17. that's 50000 tiny tiny black holes!!
18. I came, I saw, I fact checked. You didn't show a hole in spacetime where the black hole was.
19. I am convinced that the black hole in the centre of our galaxy is controlling time itself by the speed that it rotates. That every other black hole out there has its own time signature. Fast and slow time. We can only live here in this neck of the woods, so to speak. We have evolved to live here. The speed of our atoms is probably controlled by the black hole. Maybe it has slowed down People are now living longer. Certain life cycles in insects are been disrupted. The leaves don't fall in September anymore. Has the black hole got a positive and negative which it emits at both poles, probably has. It's very hard for us to measure this because we're a very small part of the Galaxy. In a car travelling very fast, say a fly inside the car would not notice this speed around it. The forces out there in space would tear us apart if we ventured far from our home here. As a species we're stuck here I'am afraid. Even our eyes have evolved to the light of our sun. Very bright light emitting diodes should be avoided because the light is different for our eyes to accept. The black hole is using up its energy, like our Sun. Nothing lasts forever in our galaxy. It probably emits the loss through its poles. Why are galaxy's pancaked shaped. This may be because the strongest gravitational field is at the equator of the black hole.
20. So, what is the difference between event horizon and ergosphere, i mean, when you enter ergoshpere you caught in the black holes pull, but the same thing does the event horizon, once you cross it, you are no more! I know im not getting something right, so please someone help. Thank you!
