Black holes. They can be so large that they can suck up universes at a time
yep.
Black holes can be many different sizes. Therefore, there are some black holes that are bigger than the sun, and there are some that are smaller than the sun.
they look like worm holes but even bigger. they are in space
A black hole has a much larger mass than a planet. The mass of a black hole, however, is contained in a point that is smaller than some fundamental particles. The event horizon of a typical stellar mass black hole is much smaller than any planet, but the event horizons of supermassive black holes are much larger.
By studying stars, planets, moons, black holes, nebulae, asteroids, comets, and everything else in space.
There are hypotheses about so called 'virtual particles' that may travel faster than speed of light, and hence are not sucked up by Black Holes. Also, Black Holes cannot suck another bigger Black Hole, when they meet a bigger one, they get sucked up rather.
It depends, Black holes can go from being microscopic to supermassive black holes that entire galaxies revolve around. It all depends on which black hole and which quasar.
most of them
Asteroids can have holes or depressions due to impacts from other objects colliding with them. These impacts can cause material to be ejected, leaving behind a crater or depression. Additionally, some asteroids may have porous or less dense regions that create apparent holes on their surface.
Yes and they would get bigger and gain more mass. So the basically combine into a bigger black hole
meteroids
When they run out of fuel they collapse and become black holes.
