Time travel possible this century? Based on Einstein's relativity equation: E=mc2?

Question

Based on Einstein's famous relativity equation: E=mc2. its possible! Mass and energy are the same thing. A time machine using light in the form of circulating lasers to warp or loop time instead of using massive objects. Twisting space causes time to be twisted. You could walk through time as you walk through space. All this is for going back in time. You won't be changing history as it will be a different universe you'll be going back into, meaning its earth in a different universe that's different from the universe earth is in now. Now, do you think all this is possible? It may take 10 or more years for this time travel machine to be perfected.

Answer 1

The possible existence of time machines remains an open question. The notion of time travel seems to carry with it a serious set of problems.

We define time travel to mean departure from a certain place and time, which is followed (from the traveller's point of view) by arrival at the same place, at an earlier—or later—(from the sedentary observer's point of view) time. Time travel paradoxes arise from the fact that departure may occur after arrival—according to one observer, and before arrival—according to another. In the terminology of special relativity, time travel implies that the timelike ordering of events is not invariant. This violates our intuitive notions of causality. However, intuition is not an infallible guide, so we must be careful. Is time travel really impossible, or is it merely another phenomenon where "impossible" means "nature is weirder than we think?" The answer is more interesting than you might think.

In current theory, the arrow of time flows in only one direction at any particular place. If this were not true, then one could not impose a 4-dimensional co-ordinate system on space-time, and many nasty consequences would result. Nevertheless, there is a scenario which is not ruled out by present knowledge. This usually requires an unusual spacetime topology (due to wormholes or strings in general relativity) which has not yet seen, but which may be possible. In this scenario the universe is well behaved in every local region; only by exploring the global properties does one discover time travel.

It is sometimes argued that time travel violates conservation laws. For example, sending mass back in time increases the amount of energy that exists at that time. Doesn't this violate conservation of energy? This argument uses the concept of a global conservation law, whereas relativistically invariant formulations of the equations of physics only imply local conservation.

A local conservation law tells us that the amount of stuff inside a small volume changes only when stuff flows in or out through the surface. A global conservation law is derived from this by integrating over all space and assuming that there is no flow in or out at infinity. If this integral cannot be performed, then global conservation does not follow. So, sending mass back in time might be all right, but it implies that something strange is happening. (Why shouldn't we be able to do the integral?)

Two recent proposals for time travel supposedly have the possibility of actually leading to practical devices (if you believe this, I have a bridge to sell you). In these schemes nothing is locally strange; time travel results from the unusual topology of spacetime. The first uses a wormhole (the inner part of a black hole which is held open and manipulated by electromagnetic forces. The second uses the conical geometry generated by an infinitely long string of mass.

One model of General Relativity is based upon "closed timelike curves" (CTCs). A CTC is a worldline that a particle or a person can follow—which ends at the same spacetime point (the same position and time) as it started. With the demonstration that general relativity contains CTCs, people began studying the problem of self-consistency. Basically, the problem is that of the "grandfather paradox": What happens if our time traveller kills her grandmother before her mother was born? In more readily analyzable terms, one can ask what are the implications of the quantum mechanical interference of the particle with its future self. There is a problem—unitarity is violated. This is related to the question of when one can do the global conservation integral discussed above.

Answer 2

You cannot interpret too much out of the mc^2 equation .This equation was first formulated by a French mathematician by the Name of Henri Poincare. The formula basically represents the energy content that was required to assemble a mass into a structure.
Your idea of twisting of space is very interesting ,Because the twisting of space configuration is really the Phenomena of the magnetic field.
The magnetic flux unit is the weber.In quantitative dimensional units, the magnetic flux is the second which is really a unit of time.
When you say we need to develop a time travel machine is quite inovative. However, we dont really need a machine. The reason is that we already are continuously moving with time all thruout space in our Galaxy and the Universe.
If you believe in our Creator then you understand that one day we will be going to Heaven to join Him and the Velocity our Soul would have to travel will be a velocity of many folds the Velocity of light and we would get there in no time at all.

Answer 3

Great creative thinking. But scientists on the edge say traveling forward in time will be what can be done, not traveling backward.
Ronald Mallett from the University of Connecticut has devised an experiment to observe a time traveling neutron in a circulating light beam. If you read the entire blog you will see Professor Mallet believes going back in time is not possible because the machine that brought you there was not built nor was the technology available. But it is feasible to go into the future.
See reference below. But I think you may have seen some of it somewhere else as your question sounds similar to what is quoted there.

Answer 4

We are all travelling forward through time at at the rate of 60 seconds per minute. What else would you like to do?

Answer 5

BUT, the problem is we must be able to travel 186000 mps^2.

WE ALSO must be traveling in a vacuum.
E=MC^2
Is Energey = Mass x The speed of light in a vacuum squared.

Answer 6

No.

Bringing several unrelated concepts together does not make a valid theory. The flow of time is affected by large relativistic accelerations, but only its rate, not its direction.

Answer 7

Every time you move, you are traveling in time. So yes, time travel will happen this century as it did in every onther century.

As far as traveling backwards in time or any kind of time travel as you describe it in your details, my answer is NO.

There are a few things in this universe that will NEVER happen. One of them is traveling backwards in time.

Answer 8

dont even think this decade.....or prolly this centuary
its gonnna take few centurays or even millineums......it requires a huge amount of energy to do tht......and u cant say for sure tht you cant change the history.....i belive tht you can if you go back in time

Answer 9

your talking about inter dimensional trans-location ,can a door way be created ? maybe . and viewing only would be recommended ,Max

Answer 10

wow what a deep thought and wow at the deeper answers ..now i have to have a coffee and process what I just read!!!
