## What is inside a Blackhole?

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..

## Can a black hole die?

The energy for this comes from the black hole, so the black hole slowly loses energy, and mass, by this process. 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.

## Does a black hole have infinite mass?

Well, even though black holes are extreme in many ways, they don’t have infinite mass—and it’s mass that determines the force of their gravity. Some black holes—known as stellar black holes. —have about the amount of mass that very massive stars do.

## Why does time stop in a black hole?

As you get closer to a black hole, the flow of time slows down, compared to flow of time far from the hole. … From the viewpoint of an observer outside the black hole, time stops. For example, an object falling into the hole would appear frozen in time at the edge of the hole.

## How fast is the speed of a black hole?

The huge black hole, known as ASASSN-14li, is spinning at least 50 percent the speed of light, research team members said. “Yet the black hole is spinning so fast it completes one rotation in about two minutes, compared to the 24 hours it takes our planet to rotate,” Remillard added.

## Is there a speed faster than light?

For one thing, while nothing has ever been observed travelling faster than light, that does not mean it is not theoretically possible to break this speed limit in very special circumstances. … There are galaxies in the Universe moving away from one another at a velocity greater than the speed of light.

## What happens to time inside a black hole?

Nothing, not even light, can escape from inside the event horizon. … Due to this effect, known as gravitational time dilation, an object falling into a black hole appears to slow as it approaches the event horizon, taking an infinite time to reach it.

## Is a black hole faster than light?

It is widely accepted that there is nothing that can travel that a speed greater than light due to Einstein’s theory of relativity. But from observational analysis of black holes it can be said that not even light can escape the event horizon of one.

## Does time exist inside a black hole?

Black holes do not exist where space and time do not exist, says new theory. (Phys.org) —The quintessential feature of a black hole is its “point of no return,” or what is more technically called its event horizon.

## Can time be stopped?

The simple answer is, “Yes, it is possible to stop time. All you need to do is travel at light speed.” The practice is, admittedly, a bit more difficult. … To phrase this tenet in a more friendly manner, it means that a light beam’s speed remains unchanged even if the observer moves relative to it.

## Does time stop at the event horizon of a black hole?

To a faraway observer, your time slows down and appears to stop for you at the horizon. Time never stops for you. … So if are far from a black hole, at the horizon, or falling inside, your measure of time is the same. To a faraway observer, your time slows down and appears to stop for you at the horizon.

## Can anything escape from a black hole?

The gravitational pull of a black hole is so strong that nothing, not even light, can escape once it gets too close. … As black holes gobble up the matter in their surroundings, they also spit out powerful jets of hot plasma containing electrons and positrons, the antimatter equivalent of electrons.

## How fast does light travel in a black hole?

The apparent motion seen by Chandra shows two X-ray knots within the jet moving at 6.3 times the speed of light for the knot closer to the black hole, and 2.4 times the speed of light for the knot farther away. (The speed of light is 186,282 miles per second, or 299,792 kilometers per second).

## What is the event horizon of a black hole?

The event horizon of a black hole is linked to the object’s escape velocity — the speed that one would need to exceed to escape the black hole’s gravitational pull. … The event horizon is the threshold around the black hole where the escape velocity surpasses the speed of light.

## What is the event horizon of a black hole quizlet?

The event horizon is an imaginary spherical outer boundary of a black hole. Once matter crosses this threshold, the speed required for it to escape the black hole’s gravitational grip is greater than the speed of light. … This is called gravity.

## What point does something become a black hole?

Any object that is smaller than its Schwarzschild radius is a black hole – in other words, anything with an escape velocity greater than the speed of light is a black hole. For something the mass of our sun would need to be squeezed into a volume with a radius of about 3 km.

## Can a black hole kill you?

But that all changed in the early 1990s when different research teams in Canada and the US discovered a second singularity called a “mass inflation singularity.” It still has a strong gravitational pull, but it would only stretch you by a finite amount, and potentially NOT kill you in the process, meaning, you might …

## Where would you look for a supermassive black hole?

Astronomers believe that supermassive black holes lie at the center of virtually all large galaxies, even our own Milky Way. Astronomers can detect them by watching for their effects on nearby stars and gas.

## How far is the event horizon from the center of a black hole?

30 kilometersThe Basics There is simply a region, or boundary, in space around a black hole beyond which we cannot see. This boundary is called the event horizon. The radius of the event horizon (proportional to the mass) is very small, only 30 kilometers for a non-spinning black hole with the mass of 10 Suns.

## What happens if you cross the event horizon?

What’s special about an event horizon is that once anything, matter or even light, passes beyond the event horizon, it can never escape from the black hole, and will continue falling towards the center of the black hole, which is called a singularity.

## How can you kill a black hole?

Black holes, the insatiable monsters of the universe, are impossible to kill with any of the weapons in our grasp. The only thing that can hasten a black hole’s demise is a cable made of cosmic strings, a hypothetical material predicted by string theory.
