      Maybe black holes are portals to the omniverse, the omniverse is a universe where everything that doesnt exist and does exist does exist, and a black hole scientifically cant be explained, maybe it's a portal to the omniverse.

    I always thought maybe we could use black holes for energy by the pressure of gravity force from black hole, let's say on a machine... maybe a test could be put a machine in black hole attach cord that collects energy pressure as soon as it breaks the machine the energy is collected.

    How exactly do they know any of this? Real science is observable and testable. This is not.

      Tardigrades are cool Day ago

      @Carlos Spiceywhiener If you want to know why they call it a hole, my guess is because any matter near it gets attracted to it is a sucking motion, giving the look of a hole sucking it up.

    • Carlos Spiceywhiener
      Carlos Spiceywhiener Day ago

      @Tardigrades are cool what doesn't reflect light? A hole? I'm not arguing what the word black means.

    • Tardigrades are cool
      Tardigrades are cool Day ago

      @Carlos Spiceywhiener It's called black because it doesn't reflect light and it has the word hole in it because some student in the 1967 suggested it.

    The particles popping into extance are matter/anti matter pairs right? So it seems like, if the anti matter one went into the black hole, it would shrink it by destroying a matter particle in the black hole. And if the matter particle was the one to go into the black hole, it would grow the black hole by one particle. So then seems like the net effect would be nothing. What am I missing here?

  • Reed Melicher
    Reed Melicher 3 days ago

    Why do we assume it becomes a singularity at the center? Why not extremely dense matter that has enough gravity to create the event horizon? Wouldn't that follow the pattern of how other stars change? Jumping to the conclusion of there being a singularity doesn't seem likely.

  • CakeP
    CakeP 3 days ago +1

    I don't understand how one of the particles popping into existence could escape. The event horizon is the point at which it is impossible to escape right? But right outside of it you would still have a massive gravitational force pulling you towards the black hole, right? So does that mean these particles can pop into existence with strong momentum already in a direction away from the hole?

      @Tardigrades are cool both of which constantly change. Gravity cannot be recreated for observation and relativity is just used to patch holes in theories

      We can understand black holes with our current understanding of gravity and relativity.

    This is so scary learning about our universe. Knowing we'll never see our sun's death. Never will get to see the Milky Way and Andromeda colide. Not getting a glance of a super nova nor a black hole. Because if these events happen, we wont see it occur. Its so scary that we can predict these but not our death. We'll eventually die, we'll die, we all die! And thats the scary part. But we can't predict that cause we're not God.

    The PBS Spacetime video on how time becomes space and vice versa in a black hole is incredibly fascinating. It locks in the "space" side of the spacetime constant equation so that essentially, mathematically, time moves in reverse when you are past the event horizon.
    Also their video on "the speed of light is not about light, but causality" or something like that is outstanding as well!

    Does hawking radiation only happen when the two particles appear EXACTLY at the event horizon, so that one is on the inside of the black hole, and one is on the outside? Or does hawking radiation happen when the two particles appear near the event horizon?

    "And what happens if you fall into one". You die. Which is, by the way, the same thing that happens to you if you DON'T fall into a black hole. Have a nice day.

    I have doubt black holes are even real. All the images and videos you've seen is fake. Scientists came up with a theory of a black hole just because they see stars circling a black area in space. They could be seeing anything and there could be a lot of explanations. Until we send a camera out there and film a black hole sucking in a star or planet then i'm gonna stay on the doubtful side.

      Have you ever seen the curve of the Earth? Neither have I. Only 500 something people have supposedly been to space, all of them under government supervision. Is space itself even real or are we living on a flat plane under a giant star speckled dome?
