No rubbish has been sent into a black hole.
Since the nearest black hole is many light years away from Earth, it's impossible for a scientist to physically travel to a black hole to study it. Instead, they have to make do with observing the effects of black holes from Earth.
Its called a Super Black-hole and scientists believe it is what holds all galaxies together.
If you go into a black hole you will be stretch out into two and then you will be crushed.
Scientists can determine the mass of a black hole through various methods, including observing the orbits of objects around the black hole, analyzing the gravitational lensing effects of the black hole on light, and studying the X-ray emissions from material falling into the black hole. These observations help scientists calculate the mass of the black hole based on the influence it has on its surroundings.
If a star was "too close" to a black hole, that star would be captured by the black hole's gravity and be pulled into it.
if you get to close
No. Earth would be destroyed if a black hole came anywhere close to it.
Objects which approach a black hole will get sucked into it.
Objects which approach a black hole will get sucked into it.
No - at least not intentionally.
if you go close enough to a black hole you can get stretched to death the end
Not all objects close to a black hole get sucked into it. The gravitational pull of a black hole depends on its mass, so objects need to get extremely close to be pulled in. Objects in stable orbits can continue to orbit the black hole without falling in.
