Can You Time Travel In Black Hole?

Can you see a black hole?

Black holes have gravitational fields so strong that even light cannot escape, so they are defined by the shell of a black, featureless sphere called an event horizon.

But the holes can nevertheless be seen.

As they consume matter that strays too close, they squeeze it into a superheated disk of glowing gas..

Can time machine be made?

Travelling in time might sound like a flight of fancy, but some physicists think it might really be possible. BBC Horizon looked at some of the most promising ideas for turning this staple of science fiction into reality. Ron Mallett has a dream: He wants to travel in time.

Is it possible to travel faster than light?

Because the concept of “speed” requires measuring a certain amount of distance traveled in space during a certain period of time, the concept of speed does not even physically exist beyond the speed of light. In fact, the phrase “faster than light” is physically meaningless.

Can we go back in time if we travel faster than light?

But to achieve true backward time travel, we’ll have to go even faster! … So, simply going faster than light does not inherently lead to backwards time travel. Very specific conditions must be met—and, of course, the speed of light remains the maximum speed of anything with mass.

How long does a black hole last?

For example, a black hole of 1 solar mass takes 1067 years to evaporate (much longer than the current age of the Universe), while a black hole of only 1011 kg will evaporate within 3 billion years.

Is it possible to travel back in time?

The Short Answer: Although humans can’t hop into a time machine and go back in time, we do know that clocks on airplanes and satellites travel at a different speed than those on Earth. … However, when we think of the phrase “time travel,” we are usually thinking of traveling faster than 1 second per second.

Where does space end?

No, they don’t believe there’s an end to space. However, we can only see a certain volume of all that’s out there. Since the universe is 13.8 billion years old, light from a galaxy more than 13.8 billion light-years away hasn’t had time to reach us yet, so we have no way of knowing such a galaxy exists.

Does space have end?

The end result is unknown; a simple estimation would have all the matter and space-time in the universe collapse into a dimensionless singularity back into how the universe started with the Big Bang, but at these scales unknown quantum effects need to be considered (see Quantum gravity).

What does space smell like?

As it turns out, space actually does have a distinct odor. … Astronauts returning from space claim that their suits smell, in a word, burnt. The lingering scent of space is “acrid” and “metallic,” reminding the astronauts of charred meat or welding fumes.

Where does a black hole lead to?

By their calculations, quantum mechanics could feasibly turn the event horizon into a giant wall of fire and anything coming into contact would burn in an instant. In that sense, black holes lead nowhere because nothing could ever get inside. This, however, violates Einstein’s general theory of relativity.

Can we create a black hole?

To make a black hole, one must concentrate mass or energy sufficiently that the escape velocity from the region in which it is concentrated exceeds the speed of light.

Can we travel time through black hole?

As for backward time travel, it is possible to find solutions in general relativity that allow for it, such as a rotating black hole. Traveling to an arbitrary point in spacetime has very limited support in theoretical physics, and is usually connected only with quantum mechanics or wormholes.

What happens to time 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. (According to Einstein’s theory, any massive body, including the Earth, produces this effect. … Inside the black hole, the flow of time itself draws falling objects into the center of the black hole.

Would we die if we entered a black hole?

Of course, no matter what type of black hole you fall into, you’re ultimately going to get torn apart by the extreme gravity. No material, especially fleshy human bodies, could survive intact. So once you pass beyond the edge of the event horizon, you’re done. There’s no getting out.

Has anyone been in a Blackhole?

Fortunately, this has never happened to anyone — black holes are too far away to pull in any matter from our solar system. But scientists have observed black holes ripping stars apart, a process that releases a tremendous amount of energy.

What would a white hole look like?

In theory, a white hole looks similar to a black hole, but instead of sucking matter in, a white hole pushes matter away. … To a spaceship crew watching from afar, a white hole looks exactly like a black hole. It has mass. It might spin.

Who died on the moon?

What would happen if a black hole hit the sun?

If the Sun were somehow compressed enough to become a black hole, it would be less than 6 kilometers (well under 4 miles) across. It would exert no more gravitational force on Earth or the other planets in the solar system than it does now.
