How big would a black hole be with the mass of the Earth?

How big would a black hole be with the mass of the Earth?

After just a few minutes more — 21 to 22 minutes total — the entire mass of the Earth would have collapsed into a black hole just 1.75 centimeters (0.69”) in diameter: the inevitable result of an Earth’s mass worth of material collapsing into a black hole.

How small does the Sun have to be to be a black hole?

For example, our Sun would become a black hole if its mass was contained within a sphere about 2.5 km across. Our Earth would need to be compressed to a size smaller than 1.77 cm across (diameter).

How big would a black hole with the mass of the moon be?

A body with the mass of our moon (about 7 million trillion tons!) would be compressed into a black hole with a diameter of only 0.2 millimeters!

What would happen if a 1mm black hole appeared on Earth?

Hossam Aly, Ph. D Astrophysics, University of Leicester, said a 1mm black hole would still have a mass of 10 percent that of Earth. If it was to hover on Earth’s surface, its gravitational pull would cover a third of the planet, tearing it up at 12 kilometres per second.

Would a tiny black hole destroy the Earth?

Earth is facing no threat because no black hole is close enough to the solar system for our planet. According to NASA, even if a black hole the same mass as the sun replace the sun, Earth still would not fall in.

Will the Sun ever explode as a Type I supernova?

Our sun isn’t massive enough to trigger a stellar explosion, called a supernova, when it dies, and it will never become a black hole either. In order to create a supernova, a star needs about 10 times the mass of our sun.

Can you be immortal in a black hole?

No, you do not become immortal flying into a black hole. Rather, you become dead.

Can the Sun survive a black hole?

Our Sun is too small a star to end its life as a black hole. But what would happen if the Sun were suddenly replaced with a black hole of the same mass? Contrary to popular belief, the Solar System would not be sucked in: a solar-mass black hole would exert no more gravitational pull than our Sun.

How big is black hole at Center of Milky Way?

Scientists had previously been able to calculate that Sagittarius A* is 16 million miles (26 million kilometers) in diameter. The Milky Way’s black hole is huge compared to the black holes left behind when massive stars die.

Is the biggest black hole bigger than the Milky Way?

The discovery is quite surprising, since the black hole is five times more massive than the Milky Way’s black hole despite the galaxy being less than five-thousandths the mass of the Milky Way.

How much mass does an object need to become a black hole?

In general, stars with final masses in the range 2 to 3 solar masses are believed to ultimately collapse to a black hole.

What happens if you touch a mini black hole?

You’d be torn apart. A black hole the size of even the smallest atom (around 0.03 nanometre radius) would have a mass of kg. At a distance of, say, 3 metres, it would produce an acceleration of much more than 100,000 newtons per kilogram, or 10,000 times Earth’s surface gravity. You’d be obliterated instantly.

How do you destroy a black hole?

The inequality suggests that to destroy a black hole, all you need to do is to feed it angular momentum and charge. But that hides a multitude of problems. For a start, things with angular momentum and charge also tend to have mass. And in any case, the equation above describes a steady state.

Has any human fell into a black hole?

No. The farthest a human has ever been from Earth is lunar orbit, approximately 400,000 kilometers from Earth. The nearest known (or suspected) black hole is about 1500 light years away.

How much mass can fit in a black hole?

Even gluttons can’t eat forever. When black holes at the hearts of galaxies swell to 50 billion times the mass of our sun, they may lose the discs of gas they use as cosmic feedlots. Most galaxies host a supermassive black hole at their centre.

How much mass do you need to create a black hole?

In general, stars with final masses in the range 2 to 3 solar masses are believed to ultimately collapse to a black hole.
