What size black hole would destroy Earth?
The Earth’s Schwarzschild radius is thought to be around 8.7mm, or roughly 17.5mm in diameter. A U.S. cent is around 19mm in diameter, so if someone were to shrink the Earth down to a little less than the size of a U.S. cent, it would become a black hole.
What would happen if a micro black hole hit Earth?
What would happen if an asteroid-mass black hole were to hit Earth? In short, catastrophe. The black hole would puncture our planet’s surface like a hot knife through butter, but it would immediately begin to slow down because of its gravitational interaction with Earth.
What are the chances of a black hole destroying Earth?
no. There is zero chance of a black hole “hitting” the Earth.
Is it possible to create a penny-sized black hole?
Theoretically yes, but practically it would be impossible to create a penny-sized black hole here on Earth. Forming a penny-sized black hole on Earth would take a huge amount of mass and a method of condensing that mass into a tiny area.
What would happen if the Earth was to fall into a black hole?
The orbit of a black hole would have to be very close to the solar system to affect Earth, which is not likely. If a black hole with the same mass as the sun were to replace the sun, Earth would not fall in. The black hole with the same mass as the sun would keep the same gravity as the sun.
What is the size of a black hole?
On the other end of the scale, some black holes are so big they are called “stupendously large black holes,” or SLABS. One, TON 618, has the mass of 66 billion suns. A stock image shows a black hole in space against a backdrop of stars. Black holes are black because their gravity is so strong that light cannot escape from them.
How much angular momentum would it take to make a black hole?
Trying to make a small (two Earth mass) black hole with all of the Earth’s angular momentum would mean that the surface would have to travel at about 10 9 times the speed of light.
