    Why black holes are call black holes? Why black holes are usually illustrated as a disc with a certain diameter? That makes no sense at all! Black holes are one or more stars, which are 3-dimensional objects, collapsed in itself, which is still a 3-dimensional object, only a lot denser than the stars were before collapsing. The black holes are as much a sphere as the original star, only smaller and denser. The event horizon is not around a disc but around a sphere. Space is not warped downwards but around the sphere in all 3 dimensions of space. A black hole is not a hole in space to somewhere else. It’s matter so dense that space is warped around it. To me calling it black stars instead of black holes would make a lot more sense.

    There is circular porthole structures, they are just as likely to be gateways as they are light absorbing machines with infinite energy. We still believe there is a sun inside the earth basically. Imagine the energy it would take to melt the core for millions of years. Why does the schuman resonance spike during major world events. The only thing we have worked out how to do is measure certain invisible forces around energy. Imagine if we just havnt made the right instrument to measure new energies or even powers that aren't based on electrical energy

    Mindblowing. I've just watched this video with a physicist friend and we have three questions. 1- How can the black holes generate their electric charge? If they are composed of "black hole matter" they shouldn't have it, or they should all have a charge proportional to their masses, and if it is due to charged particles they swallow, the electromagnetic field propagates as a wave at the speed of light, so it should not be able to go outside of the event horizon, should it? 2 - why the hawking radiation removes mass from the black hole? As I understand, it is in fact swallowing one particle, and gaining one particle of mass, not loosing it. 3 - this one is a thought experiment. If I had a very long rope, and I go near to a black hole and release the rope, so one extreme crosses the event horizon while I hold the other extreme (let's suppose I have an spaceship with enough power to keep me at a fixed distance of the black hole), what would happen? Would I be pulled into the black hole by the rope no matter what? Would the rope mechanically break due to the tension, with a piece falling inside and I keeping the other? Or once a particle of the rope crosses the event horizon it looses its bound to the rest of the rope and just falls on its own? Sorry for the long comment and the amount of questions and thank you for such amazing videos ❤

    @Bồ Công Anh it captures my motion in time even if I am outside the event horizon? And as you said, what if it is a very big black hole so the tide force is small, and I, outside the black hole, have an engin which prevents me from falling, so only part of the rope croses the event horizon?

    3. the tide will be strong enough that individual parts of the string will be rip into elementary particles and leave the rest trapped all forever. but speaking truthfully the rope and you will fall into black hole at the same rate without being stressed if the black hole is large enough,you won't feel the tide until you crossed event horizon. because black hole not just capture motion in space,they're also capture your motion in time,which mean,black hole deviated your orbit by capturing your "future".

    1. the fundamental particles that make up matter and the universe are identical. what make you and me to be completely different is the information. how they are arranged. so as the stuff fells into the black hole,the tides ripped all matter back into elementary particles. and those particles has electric charges,and that charge add to the black hole. just like mass,a fundamental property that conserved. if your mass is 70kg, as you fell into the black hole,it suddenly becomes 70 kg more massive. 2. Hawking radiation is very complicated,Stephen Hawking was made an incorrect explanation for public to easier to swallow. But simple speaking,in the process,black hole absorbing negative energy. And according to Einstein's Famous Equation relationship between mass and energy E=mc^2. we can reverse it to m=E/c^2. and you can see that negative energy given us negative mass. which mean Total mass + negative mass = Less mass. so black hole losing its mass in the process.

He fulfilled the mission that God gave him! Which is to have a death on the cross for all people in the world! * How do I get to heaven? * It's very simple! -Accept Jesus as your Lord and only Savior! - Repent of your sins daily even those you don't know because you sinned out of ignorance! -Recognize that you do not deserve God's salvation but even with your faults He wanted to save you with his great love and grace! Now about keeping your faith -Read the Bible daily -Pray and fast -Go to a church that follows the word of God May God bless you greatly! 👋

    4:43 I don't get why you are supposed to see no light while falling in a black hole.. I'd rather think the opposite occurs, since a LOT of bended light entering the black hole would have no other path to take than the one towards the center, hence would possibly find our eye balls in the way(?)
