They don't. They never have. They never will.
Black holes (in the astronomical sense) have never been made in the laboratory.
make big holes in the earth!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
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.
No. Black holes make their presence known by their extremely intense gravitational field; the gravity is so high that the theoretical "escape velocity" would be faster than light. But gravitational forces decrease in proportion to the square of the distance away from the object, and the nearest black holes are believed to be a quite distant. The Earth's gravity is not nearly so intense, but it's RIGHT HERE, and so the Earth's gravity is the only force we feel.
no black holes are stars
tornadoes tear up the earth, tilling the soil sometimes, and destroy so we can rebuild and make better. hope this answers your question.
well you wouldn't need any to make a black holes to make binary systems but what do make binary systems are two stars.
Simply put, there are no black holes close enough to pull earth in.If you mean, why doesn't earth collapse into a black hole, the repulsion between the atoms that make up earth is strong enough to resist gravity in that regard.
They do the opposite, they stretch you.
The closest known black hole to Earth is over 1,000 light-years away, so the likelihood of another black hole getting near Earth in the foreseeable future is extremely low. Additionally, the vast distances and rare occurrences of black holes make it highly improbable for one to come into close proximity to our planet.
Tornadoes have winds that can exceed 300 mph.
No, black holes do not make sound in space because sound requires a medium to travel through, and space is a vacuum with no medium for sound waves to propagate.
