>I get that black holes are formed from super novas. Any thing else?
well you can get them from anything
you just need enough mass and enough energy to shrink it past it's Schwarzschild radius
if the mass is too low the "forced" black hole would evaporate and explode
if the energy is not enough you will succeed in creating a short lived neutron star that would explode in a nova when the compressing force is gone

>Also is a black hole three dimensional?
they're 3 dimensional

>Can you measure its area, volume, or circumference?
the only thing you can measure is it's mass and it's diameter at the event horizon

>What shape is a black hole, since they aren't affected by gravity are they pentagons?
well we guess or i should rather say scientist and astronomers guess that they're round or point like
they ARE affected by gravity and they can merge into super black holes like in the center of our galaxy

>Also can you map a black hole's spin if it has one and the distance it travels if it does travel?
yes the current theory of gravity predicts that every spinning object creates an ergosphere (a region of spacetime that is being dragged by the spinning mass) and you would be able to throw something towards the black hole and see the direction that of it's spin
they do travel inertia is still a law that governs them
we can detect a black hole's position by looking at the stars behind it or detecting the gravity change if we can feel it or detect it by looking at nearby objects

you can think of black holes as stars that don't emit light
it's basically the same thing
also the existence of an ergosphere around a black hole makes us believe that it does not collapse into an infinitely small point

Rei because cute

>>2601556
look at my waifu she's going to be a physicist

>>2580854
they're energy
there's only energy
speed, matter, light are just a form of the energy of the universe

Nope, but Rei is good enough.
