is there any relation between time & black hole!?

Question

space relations

Answer 1

cosmic body of extremely intense gravity from which nothing, not even light, can escape. A black hole can be formed by the death of a massive star. When such a star has exhausted its internal thermonuclear fuels at the end of its life, it becomes unstable and gravitationally collapses inward upon itself. The crushing weight of constituent matter falling in from all sides compresses the dying star to a point of zero volume and infinite density called the singularity. Details of the structure of a black hole are calculated from Albert Einstein's general theory of relativity. The singularity constitutes the centre of a black hole and is hidden by the object's “surface,” the event horizon. Inside the event horizon the escape velocity (i.e., the velocity required for matter to escape from the gravitational field of a cosmic object) exceeds the speed of light, so that not even rays of light can escape into space. The radius of the event horizon is called the Schwarzschild radius, after the German astronomer Karl Schwarzschild, who in 1916 predicted the existence of collapsed stellar bodies that emit no radiation. The size of the Schwarzschild radius is thought to be proportional to the mass of the collapsing star. For a black hole with a mass 10 times as great as that of the Sun, the radius would be 30 km (18.6 miles).

Only the most massive stars—those of more than three solar masses—become black holes at the end of their lives. Stars with a smaller amount of mass evolve into less compressed bodies, either white dwarfs or neutron stars.

Black holes are difficult to observe on account of both their small size and the fact that they emit no light. They can be “observed,” however, by the effects of their enormous gravitational fields on nearby matter. For example, if a black hole is a member of a binary star system, matter flowing into it from its companion becomes intensely heated and then radiates X rays copiously before entering the event horizon of the black hole and disappearing forever. Many investigators believe that one of the component stars of the binary X-ray system Cygnus X-1 is a black hole. Discovered in 1971 in the constellation Cygnus, this binary consists of a blue supergiant and an invisible companion star that revolve about one another in a period of 5.6 days.

Some black holes apparently have nonstellar origins. Various astronomers have speculated that large volumes of interstellar gas collect and collapse into supermassive black holes at the centres of quasars and galaxies. A mass of gas falling rapidly into a black hole is estimated to give off more than 100 times as much energy as is released by the identical amount of mass through nuclear fusion. Accordingly, the collapse of millions or billions of solar masses of interstellar gas under gravitational force into a large black hole would account for the enormous energy output of quasars and certain galactic systems. In 1994 the Hubble Space Telescope provided conclusive evidence for the existence of a supermassive black hole at the centre of the M87 galaxy. It has a mass equal to two to three billion Suns but is no larger than the solar system. The black hole's existence can be strongly inferred from its energetic effects on an envelope of gas swirling around it at extremely high velocities. Similar evidence suggests that a massive black hole with a mass of about 2.6 million Suns lies at the centre of our own Milky Way Galaxy.

The existence of another kind of nonstellar black hole has been proposed by the British astrophysicist Stephen Hawking. According to Hawking's theory, numerous tiny primordial black holes, possibly with a mass equal to that of an asteroid or less, might have been created during the big bang, a state of extremely high temperatures and density in which the universe is thought to have originated roughly 10 billion years ago. These so-called mini black holes, unlike the more massive variety, lose mass over time and disappear. Subatomic particles such as protons and their antiparticles (i.e., antiprotons) may be created very near a mini black hole. If a proton and an antiproton escape its gravitational attraction, they annihilate each other and in so doing generate energy—energy that they in effect drain from the black hole. If this process is repeated again and again, the black hole evaporates, having lost all of its energy and thereby its mass, since these are equivalent.

Answer 2

Time is a quanttity that relates how fast a process takes place.
Black hole is a quantity of mass which was postulated by cosmology as the Remanent of a burnedout Star; the black hole constains less mass than the original Star ;therefore ,less gravity but more densisty.
So both time and mass are related in the sense that they are both measurable quantities.

Answer 3

Yes, but >>only<< in a relative sense. Imagine you're being drawn into a black hole and as you are its immense gravity will accelerate you to near light speed. To any observer not in your reference frame, i.e., some outside observer, time will be much slower than their time. Here's the kicker though --- for you time will progress at the same rate as always, but for the outside observer it will have speeded up. This is part of Einstein's relativity and has been proven to be valid in countless experiments.

Answer 4

I guess there isnt any relationship between black holes and light. However we can deduce some relationship between time and black hole and time when light passes close to black hole. If you were a light ray... the time will stop if you are in a black hole!!!!!

Answer 5

Time is an essential aspect in the evolution of a universe.
A black hole contributes nothing,eventually it's nonexistence will become apparent.

Answer 6

because of the fact of a black hollow's great gravitational pull, if gentle gets close sufficient, it only isn't waiting to flee. whether, in accordance to Einstein's concept of conventional relativity, gentle continually has to circulate a similar velocity; for this reason if gravity is pulling it in and combating it from traveling any farther, then time has to decelerate. close to a black hollow, gadgets journey much less time than for an observer (what could look to the observer to be a million 300 and sixty 5 days could purely appear as if a million 2d to the guy close to to the black hollow. as quickly as interior the progression horizon, time thoroughly stops. it is likewise theorized that very close to to the certainly singularity of a rotating black hollow, time strikes backwards; if this have been the case, the you're able to be able to desire to apply a black hollow to holiday to the previous or the destiny. yet another genuine way black holes could be related to time holiday is thru wormholes. Wormholes are theoretical suggestions to Einstein's equations for GR (conventional relativity) that decision for rips in spacetime that permit on the spot passage from one place interior the universe to a diverse by way of a black hollow, and because time is relative and various in all places of the univers, that's theoretically achievable to creat a wormhole loop going from one spot in time to a diverse and then lower back making use of wormholes. desire this clears issues up for you :)

Answer 7

Yes. Their is a relationship between Time and speed. As the speed of a substance gets closer to the speed of light, the object starts its time journey.

Answer 8

i think so
the time slows down as gravity increases
so once you are in a black hole the time stops for you as the gravity of black hole is very strong
