What is on the other end of a black hole?

According to Albert Einstein’s theory of general relativity, black holes are uninhabitable chasms of spacetime that end in a “singularity,” or a mass of infinite density. According to the startling new results, black holes do not culminate in a singularity.

Is there a backside to a black hole?

That light goes from the disk to us, straight out of the black hole’s gravity well, so it’s not as distorted. If you follow it around to the right, though, it suddenly kinks upward, forming an arch over the black hole. That’s the backside of the disk! Normally you wouldn’t see it, since it’s behind the black hole.

What’s really inside a black hole?

A black hole is a tremendous amount of matter crammed into a very small — in fact, zero — amount of space. The result is a powerful gravitational pull, from which not even light can escape — and, therefore, we have no information or insight as to what life is like inside.

How much does a teaspoon of a black hole weigh?

A neutron star has a mass of about 1.4 times the mass of the sun, but is not much bigger than a small city, about 15 km in radius. A teaspoon of neutron star material would weigh about 10 million tons. The gravitational field is intense; the escape velocity is about 0.4 times the speed of light.

How heavy is the heaviest black hole?

In a paper published today in Science, our team reports the Cygnus X-1 black hole is heavier than previously thought, weighing about 21 times the mass of the Sun. This makes it the heaviest stellar black hole — formed from the collapse of a star — ever detected without the use of gravitational waves.Bahman 30, 1399 AP

What happens if a supernova hit Earth?

Although they would be spectacular to look at, were these “predictable” supernovae to occur, they are thought to have little potential to affect Earth. It is estimated that a Type II supernova closer than eight parsecs (26 light-years) would destroy more than half of the Earth’s ozone layer.
