    Uh, I really do not know. I suspect they may have even higher dimensions...

    can you propose an idea how this might be figured out then? "higher dimensions"

    A black hole is not 3D nor is it 2D.

    now we have a very brave answer! so how do we know (any measurements or equations) that it is in 2-D?

    That person said that its not in 2D either ...

    oh I missed that! so what is the geometrical shape of a black hole then?

    Spherical according to this: http://physics.stackexchange.com/questions/72824/what-is-the-shape-of-a-black-hole

    LOL the link is educational and as long as its educational, its allowed. TK is a mod and so am I, so ... :)

    I have linked to an educational site in the past and I was warned that it was not allowed

    Some people mistakenly report others, but that doesn't mean you make a big deal out of it, y'know?

    going back to the topic of shape of black holes!

    Good luck with that! I suggest you go inside a black hole and find out yourself, would be fun! :)

    Some people think of black holes as being circles, or worse, funnel-shaped. The funnel thing is a misconception from people trying to explain gravity as a bending in space, and they simplify things by collapsing 3D space into 2D; they say the space is like a bed sheet, and objects with mass bend space the same way that a massive object (a bowling ball, say) will warp a bed sheet. But space is not 2D, it’s 3D (even 4D if you include time) and so this explanation can confuse people about the actual shape of a black hole event horizon.

    so does it have a shape or nah?

    do you know black holes at all or you're just pretending to know it?

    I’ve had kids ask me what happens if you approach a black hole from underneath! They sometimes don’t get that black holes are spheres, and there is no underneath. I blame the funnel story. Sadly, it’s the best analogy I’ve seen, so we’re stuck with it. Use it with care.I’ve had kids ask me what happens if you approach a black hole from underneath!

I will cite my info. Just a sec.

    so by saying that the shape is sphere, are you trying to say that it has a 3-D shape? it appears that you are now contradicting yourself :(

    how do you know that it is a fact? we do not use facts in science! we use theories and laws, which are seen above and more important description than facts.

    I never pretend..I share the few facts I have concerning an amazing subject. My goal if for my Open Study friends to expound on subjects I love and offer better information regarding the subject! :)

    since "educational" links are allowed, per an open study moderator, then let me share what will help us determine the shape of a black hole if there's indeed one that all share.

    I agree with you! Thank you! what can I say? Black holes are weird.
