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.
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.
Because in the past other asteroids have crashed in to it.
they look like worm holes but even bigger. they are in space
By studying stars, planets, moons, black holes, nebulae, asteroids, comets, and everything else in space.
5 names in our solar system are............. planets.................stars....................asteroids....................moon................... black holes
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.
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.
most of them
The moon has holes because it has been hit by asteroids
meteroids
