How large would the Sun be if it was a black hole?

How large would the Sun be if it was a black hole?

Using the Schwarzschild radius calculation, a black hole the size of Earth would have a radius of less than one inch, making it about as big as a ping pong ball. The Sun, on the other hand, would have a radius of just under two miles.

How big would a 1 solar mass black hole be?

The mass of a black hole is usually expressed in something called a “solar mass.” One solar mass is defined as the mass of our Sun. This is a very large number, about 2 x 10^30 kilograms. That’s 2 with 30 zeroes after it, or written out: 2,000,000,000,000,000,000,000,000,000,000.

How small would the Earth have to be to be a black hole?

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 if the Sun was blue?

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.

How big would TON 618 be if it were a star?

TON 618 is as bright as 140 trillion suns and has a mass of about 66 billion suns. For comparison, all the stars in our galaxy combined share a mass of only 64 billion suns. That is, TON 618 is over 15,000 times more massive than Sagittarius A*. That’s a staggering number.

What size black hole could destroy 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.

What is the heaviest thing in the universe?

So massive stars become neutron stars – the heaviest things in the universe – and even more massive stars become black holes.

Can a black hole destroy a galaxy?

No. There is no way a black hole would eat an entire galaxy. The gravitational reach of supermassive black holes contained in the middle of galaxies is large, but not nearly large enough for eating the whole galaxy.

Has any human fell into a black hole?

No. The nearest black hole is believed to be in the V616 Monocerotis system, 3,000 light years away. The farthest humans have traveled is to the moon.

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.

What if sun was red?

A star’s habitable zone, or the region around the star where temperatures are warm enough for a planet’s surface to sustain liquid water, depends on the star’s temperature and brightness. As a red giant, our Sun will expand and heat up, forcing its current habitable zone, which now encompasses Earth, outward.

Could we survive sun exploding?

For Earth to be completely safe from a supernova, we’d need to be at least 50 to 100 light-years away! But the good news is that, if the Sun were to explode tomorrow, the resulting shockwave wouldn’t be strong enough to destroy the whole Earth.

Why did ancient people not see blue?

Even blue pigments and blue gems and rocks were rare in antiquity. People back then didn’t need as many adjectives for color as modern times because there was nothing in their life in a hue beyond what they used. Blue didn’t appear in Chinese stories, the Icelandic Sagas, or ancient Hebrew versions of the Bible.

What would a black hole Sun look like?

How many suns are equivalent to a black hole?

Black hole equal to 2,00,000 suns could shed light on how these supermassive objects grow – India Today.

How big is the Sun compared to 618?

Consider the largest known Black hole, TON 618. It has a mass of 66 Billion solar masses. (66 billion times the mass of our Sun). If TON618, were placed on our solar system, its event horizon would extend out towards the Oort cloud.
