It is said that gravity and time may be tied together somehow. I hasn't been proven yet. A black hole is a large mass that has so much gravity that light can't even escape the pull of it. The density of this mass is such that a bb sized piece of it would weigh as much as the earth or more. Humans wouldn't be able to survive even being within 100 million miles of a black hole. You would be ripped apart by the intense gravity.

A black hole is nothing but a dead star or the last stage of a star whose mass is less than that of the solar mass. In this phase of the star, the gravitational force force become extremely high that even light cannot escape from its field. According to Einstein, a black hole helps us by bending the light from a star that is located exactly behind it or a nearby star. With this bent light we can examine the nature of the star or a quasar. A supermassive black hole called Saggitarius A with is situated exactly at the center of our galaxy is responsible for the stability of our galaxy.
Whereas, travelling back in time a supernatural mystery which has not been accepted by the scientific society.

A black hole is a dead star. A star (like our Sun), eventually will consume up it's energy source (nitrogen and hidrogen) and will blow up into a red giant, hundreds time bigger in size from it's original size. Then, it will shrink into a small but very massive object. This object is what they call "the black hole". It is very massive and the gravity is very strong. It sucks everything, even light couldn't escape from it. That's why it's called a black hole.

The black hole is sometimes connected to time travel because it is believed that it can open a "wormhole", a passage through space and time. This wormhole is very unstable. It will be closed the moment it is opened. There are nothing known up to this day that can hold the opening of a wormhole long enough for an object to enter it.

A black hole is not related with traveling back in time.
A black hole is a concentration of mass whose gravitational field is so strong that nothing can escape, even light.
A black hole could help us go forward in time by making us go so fast that time seems to slow down.

Blackhole is a star that has died, I mean it has burnt up the H2 and made Helium. Then Helium turns to wieghtier stuff. Finally if these compounds are too heavy for the star to contain, it implodes due to gravitational pull. This implosion increases its weight, thereby increasing gravity. This goes on until the gravity is so high that even light cant escape the star., That is a black hole. Black holes cannot transfer people through time but worm holes can. Ask another question on that!

A black hole is a dead star with incredibly high density. It is actually linked to forward time travel because of the way space time is warped near a large gravitational field relative to say, an observer on Earth. This is part of Einstien's general theory of relativity. Backward time travel is still mostly in the realm of Sci Fi and theoretical physics, but few people say "never" anymore.

Black hole is an object whose gravitational pull inside a certain radius is so strong that nothing, not even light can escape it. A black hole forms when the amount of matter in the core of a star undergoing a supernova is great enough to cause a runaway gravitational collapse

IT IS NOT RELATED TO TRAVEL BACK IN TIME AND NO ONE CAN TRAVEL BACK IN TIME

Black holes are a theoritical concept. It is too bad the concept is all wrong. The answer to what you seek is rather long, but that is dictated by the question. It is a short paper contained within, "The Bones of Time."

THE PROBLEM AND REPAIR OF RELATIVITY

(C) 2004, Duane Ertle


In order to introduce the problem, I am going to quote a few sentences from a book "The Universe and Dr. Einstein," by Lincoln Barnett, published in 1960 by Mentor Books. The quotes are from pages 61 and 63 respectively.


The first concept involves that of mass.

"In its popular sense, mass is just another word for weight. But used by the physicist, it denotes a rather different and more fundamental property of matter: namely, resistance to a change of motion. A greater force is necessary to move or stop a freight car than a velocipede; the freight car resists a change in its motion more stubbornly than the velocipede because it has greater mass. ... But Relativity asserts that the mass of a moving body is by no means constant, but increases with its velocity relative to an observer. In short, energy has mass!"


Next, we need to look at the reason for this belief.

"By further deduction from his principle of Relativity of mass, Einstein arrived at a conclusion of incalculable importance to the world. His train of reasoning ran somewhat as follows: since the mass of a moving body increases as its motion increases, and since motion is a form of energy (kinetic energy), then the increased mass of a moving body comes from its increased energy. ..."


Now I am going to quote a paragraph from "The Bones of Time," copyrighted in 1978 by Duane Ertle, it is from the chapter "Flexible Time."

"The reason a fast moving mass is so difficult to stop, or have a direction change in, is due to its becoming frozen in a linear manner so energy cannot pass through its total volume as happens when it is at rest. When a mass moves at one-hundred thousand miles a second, the energy existent and having potential movement at right angles to its direction of travel could be at most a distance of eighty-six thousand miles a second. When moving at the speed of light minus two feet per second, the potential energy existent at right angles to its forward motion would only be two feet in one second. At the speed of light the mass would convert from being a three-dimensional object and would become a single beam of high energy photons streaking through space, all existing in only one dimension. Obviously there would be zero energy potential at right angles to the direction of travel."

Moving mass does not acquire additional mass as it moves. Atomic matter is composed of waveform. As electromagnetic energy (a wave) has differing energy values so, also, does mass at different speeds have an overall differing waveform. The waveform is derived from the moving mass itself, as energy at right angles to direction of travel decreases in line density with movement, and transfers a proportional amount of that frequency toward the direction of travel. In this sense greater mass is being added to the forward motion of the mass at the expense of the energy/mass at right angles to it.

There is an expression that deals with frequency density and an increase of energy as the lines of frequency increase. The expression in question says that E=hf. The energy of an electromagnetic wave is equal to that of a very small numerical constant times the frequency of the wave. The greater the frequency of the wave, the more energy the electromagnetic wave would have. Radio waves may have very long peak-to-peak distances of thousands of meters, while cosmic radiation is able to have its frequency so compressed that it acts as dimensional mass, and there may be trillions of frequencies, or waves within a single meter. Now consider how the frequency at right angles to direction of movement changes from having great potential in those directions, toward having less, thus giving up mass/energy potential. Energy, in form of greater frequency, converts to an overall change of mass, or as some would say, "... resistance to a change of motion."

The concept of E=hf is an equation that works for three different elements of nature:

1. E=hf, is an equation that describes why electromagnetic energy has greater and lesser energy values. Radio waves have very little energy value, while gamma and cosmic radiation have a great deal. And it all is dependent upon wave frequency and the density of that wave in a particular space.

2. mk=hf, (mass kinetic energy, equals hf) describes why mass shrinks to an observer as it moves. Because mass is composed of electromagnetic energy, it has the same wave values as electromagnetic energy, but in a very condensed manner. Electromagnetic energy remains in three-dimensional space in form of standing waves, yet having the same linear value of 186,000 mps all the while. Like a runner on a racetrack traveling all the while at that great speed. The same distance is traveled, just not in a straight line. As long as the velocity value within mass maintains the value of "c" it does not matter how small the "race track" becomes.

The, mk=hf, value demonstrates that the shrinkage of a moving mass is constant with frequency change. There are no sudden changes in mass/energy values. It also explains why the energy transfer takes place as frequency converts at right angles to that of forward motion. Just as sound waves have greater frequency with greater mass speed (thus the lines of frequency shrink, or become compressed) so, also, mass in the direction of travel shrinks in proportion to a greater or lesser internal frequency or energy values.

3. c=hf, is that for the relationship of a gravitational field and its frequency. It is possible that a "graviton," a single gravitational wave, has the same frequency as all other gravitational waves, no matter where they form; and what we consider as field of gravity has to do with quantity and not quality. Even though it might be either way, at present it appears that a gravitational field is formed of a quantity of waves (a greater multitude of waves all exactly the same no matter where in earth they formed) and not their frequency; although the c=hf concept would be valid in either sense.

Dr. Einstein understood moving mass from the perspective of how it related directly to that of energy - and it worked for him. He arrived at E=mc2! But the same result is able to be found by understanding that mass is composed of waves, and the moving mass undergoes a change from being greater in mass in three dimensions toward that of becoming greater in waveform in one direction and less in the other two dimensions.


In order that the reader may understand the thinking of today concerning the potential ramification of compounding mass, I am going to quote a paragraph found in a book entitled "Asimov's Guide to Science," (c) 1972; published by Basic Books Inc..

"... When Oppenheimer worked out the properties of the neutron star in 1939, he predicted also that it was possible for a star that was massive enough and cool enough, to collapse altogether to nothingness. When such collapse proceeded past the neutron star stage, the gravitational field would become so intense that no matter what, no light could escape from it. Nothing could be seen of it; it would simply be a "black hole" in space."

To which concept I would say; Oppenheimer did not realize that the force of gravity is a field of energy, c2=E/m, initiated by the heat energy within a solar mass. No heat - no energy.

Black holes today are an attempt to explain why so much mass is missing from creation - 90%. The galaxies have been stretched out, and there is not enough mass in empty space to account for distances outward and their being so far apart from each other. But, that condition is not really new news. In the book of Isaiah 45:12 God said 2700 years ago that the heavens had been stretched out. "I have made the earth, and created man upon it, I, even my hands, have stretched out the heavens, and all their host have I commanded." So, then, it is not 'black holes" that mankind needs to find, but God.

The conclusion is this. Because moving mass has increased frequency change in direction of movement until it reaches the speed of light, it then converts into radiation; there is no manner by which a black hole is able to form under any condition. There is no manner whereby the mass in question may be anything other than the original mass converted into what it already, intrinsically, was. This means, if it is impossible for a black hole to form, then it is just as impossible for the "big bang" to have happened. Neither of these events ever did exist nor shall they. They both soon shall disappear with a "little poof" into an obscure page somewhere in antiquity.
