Time Travel Theory

Recommended Posts

A viable theory of time travel would lead one to the engineering blueprints for a working temporal displacement device.

Time travel to the future is relatively easy compared to the challenge of going into the past. While we are sitting here doing nothing, we are marching steadfastly into the future ...moment by moment. 

Get into a rocket-ship and accelerate up to a significant fraction of the speed of light, then return home. Time passes more slowly for people in the rocket. When they return to the Earth they discover while only 5 years have passed for them, 50 years has elapsed on the Earth. 

Or you could find the nearest black hole and get close to it but not too close, and orbit around it a few times. The massive gravity of the black hole would slow time considerably. After returning home, there would again be a considerable amount of time that has transpired on the Earth while your experience of gravitational time dilation(slowing of time) around the massive black hole would mean you have aged much less and basically time travelled into the future. 

As for going back to the past, there is the problematic grandfather paradox. Go back in history and murder your grandparent but then you would not even exist, so how could we travel back in time in the first place? One way to solve this apparent paradox is with the many-worlds theory, whereby, when we travel back to the past a new branch of time is generated. Thereby a new parallel world of possibility is created and we still retain or "remember" knowledge from the alternate future. 

What if... our universe is like a giant clock that can unwind itself in the reverse direction of time? If we experienced such temporal unwinding we would not remember it. That is because our memory would be erased as time was being reversed in the cosmos. Consequently, as the universe chronologically unwinds, our bodies grow younger while our memory is erased. Then it stops and we begin the relentless march forward again – none the wiser to what has actually happened.

This revelation of the chronological unwinding of the universe got me to thinking about a design for a time machine called the time-sphere. 

Exotic matter is required in order to warp space-time enough to time travel. This exotic substance is also referred to as negative mass.  The outer time sphere requires an inner sphere that is shielded from another layer of negative mass that envelopes the inner sphere. When the outer sphere is spinning the negative mass in it begins rotating at high speeds as the inner sphere remains anchored and does not move. The negative mass in the outer sphere begins reversing in time as it warps space-time.

The outer shell carries the inner shell along with it into the past. Since the contents of the inner shell are still moving forward in the thermodynamic direction of time, there is no memory loss or reversed aging. Essentially this is a tunnel in time to our chosen destination in history. It can also be referred to as the classic wormhole or stargate... Once we reach our temporal destination that is still at the same spatial location on the Earth, the rotation of the outer sphere is turned off and both spheres are synchronized into the forward moving time of the past. An observer in the present would see the time-sphere suddenly disappear when its time is reversed due to the rotation of the outer shell.

Alternatively, if it is discovered that negative mass is not viable then it might be possible to use miniature black holes that can also be rotated at high speed, thereby providing another form of protective shell for the occupant's thermodynamic arrow of time within it.

A time capsule is one way to communicate with people of the far future. It is a way of storing information for a long duration. Then... it can be read and interpreted by our future generations. 

Eons from now, our posterity may store history on a vast holographic array. Then they may even read these internet forum posts about time travel. A future genius may be searching for certain keywords, symbols, and statements in order to solve some enigmatic problems existing in that future.

I have been perusing some of the old John Titor postings and I see that he posted as TimeTravel_0.  The "0" or zero seems to imply an origin or nexus point similarly to the origin on the Cartesian coordinate diagram.  The "original" time traveler TT_0.  Thus such a temporal nexus in this universe may be of great interest to all future time historians.

Hopefully, more time-voyagers in the future may read this thread and consequently travel back to this point in time to help us out with a few semi-anonymous postings and tips on the "how to" for constructing a time machine. 

All motion is relative, including motion through time. No material object can travel faster than the speed of light in vacuum though. But if one could travel faster than light they could go backwards in time. Theoretically speaking, warping space-time and traversable wormholes allow for shortcuts through the malleable fabric of space and time without breaking the laws of physics. Space-time is very stiff though. It takes much mass and energy to put an appreciable dent in its fabric. Of course we can imagine time differentials when we are inside of a transparent spherical force-field and can observe the world changing around us. The time bubble as illustrated in the first post of this thread contains matter and objects still ticking along at their own proper rate of forward marching time even as the outside world is ticking at fast-forward or fast-reverse. But still, the law of gravity would hold our time-sphere at that specific location in either direction of forwards or backwards time. 

Any time travelers out there from the future when time travel exists who are physicists or engineers? Please stop by and give us some necessary clues for building a time machine...

After some more google research I found a patent application for a time machine. A little more digging revealed that the applicant for this patent has been convicted of some very deplorable deeds.  

They say there is a fine line between genius and insanity. I will study the patent application to see if it has any merits.  The diagrams look very similar to the Titor diagrams I have viewed online...

Jack Sarfatti has written about some interesting ideas regarding low power warp drive and metamaterials.  With such metamaterials it may be possible to use light to warp spacetime and thus attain a better way to reverse time externally to the machine and/or speed it up either backwards or forwards, thus achieving practical time travel.
