Question: How Does Mass Relate To The Powerful Gravitational Force Of A Black Hole?

What is the gravitational force of the black holes?

A black hole is a region of spacetime exhibiting gravitational acceleration so strong that nothing—no particles or even electromagnetic radiation such as light—can escape from it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.

How does gravity affect black holes?

A black hole is a place in space where gravity pulls so much that even light can not get out. The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying. Because no light can get out, people can’t see black holes.

How does a massive star become a black hole?

Stellar black holes form when the center of a very massive star collapses in upon itself. This collapse also causes a supernova, or an exploding star, that blasts part of the star into space. Scientists think supermassive black holes formed at the same time as the galaxy they are in.

What’s inside a black hole?

“A black hole is an object so massive that its extreme gravity makes everything, even light, fall inward,” Monreal says. Black holes warp the space and time around it (together called spacetime) the same way. “From a black hole, even the speed of light isn’t enough to escape,” Monreal says.

Is space a time?

Space-time. Space-time, in physical science, single concept that recognizes the union of space and time, first proposed by the mathematician Hermann Minkowski in 1908 as a way to reformulate Albert Einstein’s special theory of relativity (1905). Common intuition previously supposed no connection between space and time.

Can black holes die?

The black hole would then lose the rest of its mass in a short amount of time as abrupt explosions—we can detect these explosions as gamma ray bursts. The end. So, yes, black holes do die, and they do so when the theories of the extremely large come together with the theories of the very small.

How Is time travel possible?

This can be achieved by traveling at relativistic speeds or through the effects of gravity. For two identical clocks moving relative to each other without accelerating, each clock measures the other to be ticking slower. This is possible due to the relativity of simultaneity.

Does time slow near 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. Near a black hole, the slowing of time is extreme.

Is the universe a black hole?

In the version as originally proposed by Pathria and Good, and studied more recently by, among others, Nikodem Popławski, the observable universe is the interior of a black hole existing as one of possibly many inside a larger parent universe, or multiverse.

Is a black hole a dying star?

A stellar black hole (or stellar-mass black hole) is a black hole formed by the gravitational collapse of a star. They have masses ranging from about 5 to several tens of solar masses. The process is observed as a hypernova explosion or as a gamma ray burst. These black holes are also referred to as collapsars.

Is there a black hole at the center of our galaxy?

Astronomers are very confident that the Milky Way galaxy has a supermassive black hole at its center, 26,000 light-years from the Solar System, in a region called Sagittarius A* because: No known astronomical object other than a black hole can contain 4.1 million M ☉ in this volume of space.

What is a white hole NASA?

In general relativity, a white hole is a hypothetical region of spacetime which cannot be entered from the outside, although matter and light can escape from it. In this sense, it is the reverse of a black hole, which can be entered only from the outside and from which matter and light cannot escape.

Do wormholes exist?

A wormhole can be visualized as a tunnel with two ends at separate points in spacetime (i.e., different locations, or different points in time, or both). Wormholes are consistent with the general theory of relativity, but whether wormholes actually exist remains to be seen.

What is beyond black hole?

In astrophysics, an event horizon is a boundary beyond which events cannot affect an observer. Later, in 1958, David Finkelstein using General Relativity introduced a more strict definition of a local black hole event horizon as a boundary beyond which events of any kind cannot affect any outside observer.

How do you create a black hole?

In principle, a black hole can have any mass equal to or above about 2.2×10−8 kg or 22 micrograms (the Planck mass). 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.
