How long would a black hole with the mass of the Earth last?

A supermassive black hole with a mass of 1011 (100 billion) M ☉ will evaporate in around 2×10100 years.

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

0.2 millimeters
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 size would a black hole be if it was the same mass as Earth?

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. The reason the Earth will be destroyed but not simply swallowed up is because the Earth will be resisting the black hole in at least two ways.

How do you calculate the lifespan of a black hole?

t=(MM⊙)3×1.160×1067yr, where M⊙=1.989×1030 kg M ⊙ = 1.989 × 10 30 k g . The lifetime of a 1 M⊙ 1 M ⊙ black hole, therefore, is calculated as nearly 57 orders of magnitude longer than the present age of the universe.

Can a black hole have a moon?

Dark Matter Evidence The paper’s authors believe that evidence of these miniature black holes could shed light on dark matter, the elusive stuff that many physicists believe accounts for the majority of matter in the universe.

How long does it take for a black hole to evaporate?

It would take a whopping ~10^67 years for a black hole the mass of the Sun to evaporate, and around ~10^100 years for the largest black holes in the Universe. That may be far longer than the age of the Universe, but it’s still not forever.

What happens when two particles fall into a black hole?

If such a pair is created right on the event horizon, or the boundary, of a black hole, one particle may fall in while the other barely escapes, taking with it a minuscule amount of energy and therefore mass from the black hole. This theoretical phenomenon is known as Hawking radiation.

Is it possible to escape from a black hole?

In 1974, Stephen Hawking proved that, from a quantum perspective, escape from a black hole is possible, though it is very slow. Latent energy (quantum fluctuations) in the fabric of space-time may cause pairs of virtual particles to pop into existence throughout the universe.

How big is the black hole at the center of a galaxy?

In 2015, researchers discovered a black hole named CID-947 that grew much more quickly than its host galaxy. The black hole at the galaxy’s center is nearly 7 billion times the mass of our Sun, placing it among the most massive black holes discovered. The galaxy’s mass, however, is considered normal.
