What's the gravity of a black hole?

The black hole would have the same gravity as the sun. Earth and the other planets would orbit the black hole as they orbit the sun now.

What is the gravitational pull in a black hole?

As these few dozen stars, called S-stars, approach the black hole—which is about four million times more massive than the sun—its immense gravitational force whips them around faster than 16 million miles per hour.

Is a black hole infinite gravity?

A black hole has an infinite density; since its volume is zero, it is compressed to the very limit. So it also has infinite gravity, and sucks anything which is near it!

Does time stop in a black hole?

Time does stop at the event horizon of a black hole, but only as seen by someone outside the black hole. This is because any physical signal will get infinitely redshifted at the event horizon, thus never reaching the outside observer. Someone falling into a black hole, however, would not see time stop.

Can a wormhole exist?

In the early days of research on black holes, before they even had that name, physicists did not yet know if these bizarre objects existed in the real world.

How Does Gravity Escape A Black Hole?

How hot is a black hole?

Black holes are freezing cold on the inside, but incredibly hot just outside. The internal temperature of a black hole with the mass of our Sun is around one-millionth of a degree above absolute zero.

How much force is in a black hole?

For a 1 solar mass nonspinning black hole, ignoring tidal forces, you'd pull 153 trillion G's at the event horizon. In technical terms, you would be very very dead. For Holmberg 15A, the largest known black hole at 170 billion solar masses, you'd pull only 9.021 G's.

What is a white black hole?

White holes are theoretical cosmic regions that function in the opposite way to black holes. Just as nothing can escape a black hole, nothing can enter a white hole. White holes were long thought to be a figment of general relativity born from the same equations as their collapsed star brethren, black holes.

Do we live in white holes?

There are no known physical circumstances that can lead to the existence of white holes. They are purely hypothetical (due to the math). Though Smolin says that they actually exist on the other side of black holes.

What would happen if two black holes collide?

It is possible for two black holes to collide. Once they come so close that they cannot escape each other's gravity, they will merge to become one bigger black hole. Such an event would be extremely violent. Even when simulating this event on powerful computers, we cannot fully understand it.

Are black holes wormholes?

The main difference between a black hole and a wormhole is where they physically end. Black holes come to a point of extreme density called a singularity from which nothing can escape – not even wavelengths of light. A wormhole has two open ends which hypothetically connect two different points in time and space.

Is a black hole a solid liquid or gas?

When astronomers speak about them, they often make an unintentional impression that they are some kind solid objects. They are not. A black hole is a spacetime singularity that is enclosed by an event horizon. Both things are quite weird, but none of them is anything solid.

Can anything survive a black hole?

Regardless of the explanation, we do know that it is highly unlikely that anyone entering a black hole would survive. Nothing escapes a black hole. Any trip into a black hole would be one way. The gravity is too strong and you could not go back in space and time to return home.

Can the speed of light escape a black hole?

Answer: Within the event horizon of a black hole space is curved to the point where all paths that light might take to exit the event horizon point back inside the event horizon. This is the reason why light cannot escape a black hole.

Is absolute zero Possible?

Physicists acknowledge they can never reach the coldest conceivable temperature, known as absolute zero and long ago calculated to be minus 459.67°F.

What is the hottest thing in our universe?

The hottest thing in the Universe: Supernova

The temperatures at the core during the explosion soar up to 100 billion degrees Celsius, 6000 times the temperature of the Sun's core.

How cold is space?

The Cosmic Background Explorer (COBE) satellite has refined temperature measurements taken way back in 1964. According to data from the Cosmic Background Explorer (COBE) satellite, the temperature of space is 2.725K (2.725 degrees above absolute zero).

Is there a white hole?

White holes cannot exist, since they violate the second law of thermodynamics. General Relativity is time symmetric. It does not know about the second law of thermodynamics, and it does not know about which way cause and effect go.

Can humans create a black hole?

To study the phenomenon more closely, physicists in Israel managed to create a lab-grown, analogue black hole using some thousand atoms. This faux black hole exhibited all properties of a black hole in the state in which it is believed to exist in space.

Can humans turn into black holes?

Interstellar is a little less fiction now.

A human could theoretically safely fall into a black hole if the black hole is large enough and completely isolated.

Do black holes eat space?

Is it possible for a black hole to "eat" an entire 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.

What is in center of black hole?

The singularity constitutes the center of a black hole, hidden by the object's “surface,” the event horizon. Inside the event horizon, the escape velocity exceeds the speed of light so that not even rays of light can escape into space.

Do stars fall in black holes?

The black hole immediately swallows half the star's matter while the rest arcs away in long streamers. These rapidly fall back and settle into an accretion disk that steadily feeds material into the black hole, growing so hot that it emits copious x-rays.

Can time be bent?

So to answer your question, time does not literally "bend". A massive object modifies the proper time interval around it such that an outside observer would see objects near the mass experience less time and spacetime intervals would have their spatial components modified accordingly.

How many dimensions are there?

The world as we know it has three dimensions of space—length, width and depth—and one dimension of time. But there's the mind-bending possibility that many more dimensions exist out there. According to string theory, one of the leading physics model of the last half century, the universe operates with 10 dimensions.
