No - at least not intentionally.
Scientists are concerned about the ozone hole. They are trying to ban the CFC's over the world.
Its called a Super Black-hole and scientists believe it is what holds all galaxies together.
No rubbish has been sent into a black hole.
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.
Uh...the obvious. They produce and reflect no light at all (black) and stuff goes in it (hole.)
Yes. Intermediate-mass blackhole is a medium size black hole. Scientists have found stellar black holes and supermassive black holes but there is no prove that Intermediate-mass black type of black holes exist. My opinion is that they do exist because when a black hole is becoming a black hole supermassiveblack hole it will need to go though this stage of intermediate-mass black hole.
scientists think that the Big Bang which generated the univerese waas the consequence of the explosion of a massive black hole. so the big bang
Scientists cannot be certain, as we have yet to experiment with a black hole, but they theorize that time would slow down relative to time far from the black hole.
Scientists aren't even sureother universes exist. The possibility a black hole could even lead somewhere else is practically impossible. Whatever enters a black hole is virtually destroyed in a flash of raw energy. That's why scientists think that 99.999999999999% of the universe's antimatter is in black holes.
Black holes do exist - they are just VERY difficult to detect.
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.
