The Earth would be destroyed, but the whole planet would not be swallowed up by the black hole. A black hole with a Schwarzschild radius of about a centimeter, which would make it about the size of a coin, would have about the same mass as the Earth.Feb 10, 2014
Would a small black hole destroy Earth?
Could a Black Hole Destroy Earth? Black holes do not go around in space eating stars, moons and planets. Earth will not fall into a black hole because no black hole is close enough to the solar system for Earth to do that.
How close can a black hole be to swallow Earth?
This black hole is 6.6 times more massive than our sun. (That means it has a lot of mass, which means it has a really strong gravitational pull — much stronger than even our sun's gravitational pull.) If Earth gets within about 800,000 kilometers (3.7 light-seconds) of this black hole, it will get pulled apart.
What if there was a small black hole on Earth?
The edge of the Earth closest to the black hole would feel a much stronger force than the far side. As such, the doom of the entire planet would be at hand. We would be pulled apart.
How long would it take for a mini black hole to eat the Earth?
If you assume that the black hole would only consume atoms that it happens to run into, then I calculate that it would take about 1028 years for it to consume the entire Earth, far longer than the age of the Universe. This assumes that the black hole wouldn't lose any mass due to Hawking radiation.
What happens if a 1mm black hole appeared on Earth?
A small black hole is considered to have a mass at least six times that of the Sun – but even one just 1mm in size could still wreak havoc, an expert has said. Hypothetically, if one of that size were to form on Earth, its immense gravitational pull could still tear the planet apart.
Is Earth inside a black hole?
Our universe may reside within a vast, black hole. Let's rewind the clock. Before humans existed, before Earth formed, before the sun ignited, before galaxies arose, before light could even shine, there was the Big Bang. This happened 13.8 billion years ago.
What would happen if the Sun exploded?
The Sun will get hotter and brighter, and it will start to expand. During this process, it will lose its outer layers to the cosmos, leading to the creation of other stars and planets in the same way that the violent burst of the Big Bang created Earth.
What is a white black hole?
White holes are theoretical cosmic regions that function in the opposite way to black holes. Just as nothing can escape a black hole, nothing can enter a white hole. White holes were long thought to be a figment of general relativity born from the same equations as their collapsed star brethren, black holes.
What can destroy a black hole?
Eventually, in theory, black holes will evaporate through Hawking radiation. But it would take much longer than the entire age of the universe for most black holes we know about to significantly evaporate.
