is there any proposed measurement for time travlle all ready?

Well, what I think is, that the measurements should be able to work with mixturing them with the space and other measurements. The formuals of time should also include this measurements, to be able to work between them.

I have thought about using seconds per minute or something like this. Using more, would be littile scientific, although maybe more efficient to machines (like in cars, we use km/h not m/s, so in time machines, it could be s/hours...). The problem with this is coming to acceleration. How could you do a formula of acceleration for time travell? would it be: (ft-it)/t? were t= time, f= final and i=inicial.

What other formula's of time travell would you use/introduce/create?

what measurements do ou think should be used in time travell?

the change in time is conjugated to the change in energy. This is one of the uncertainty conditions of quantum mechanics.



This formulation is experimentally verified by high energy physics measurements.

When quantum mechanics is combined with special relativisty as done in Dirac's equation, QED, QCD, and the Standard Model, it was detected that high energy particles approaching the speed of light live a lot longer than when they just travel at normal speed.

The conclusion is that when you travel at the speed of light, you cannot grow older. Your body clock does not move.

not even at a really high gravity point? or at the lowest one?

According to special relativity, when matter reached light speed, its mass become infinite. therefore it becomes a black hole or a singularity of zero volume.

acording to this density has much to do with gravity-I had already perceived this: thanks for confirming.

And, what is the relation between time-spedd of light-matter-energy?

According to general relativity (GR), the rate of change of time with respect to a spacetime coordinate system is a variable in non-Euclidean geometries instead of being a constant in n-dimensional Euclidean spacetime. GR asserts that the curvature of spacetime is equal to energy-momentum tensor.

I guess that according to my speed and acceleration time-travelling formulas we could get the force an object has in time-travelling:

F=m[(ft-it)/t)]

ft=final time
it=initial time
t=time duration of time-travelling)
m=mass
F=force

then, the energy of time travelling, which I am going to define as "time energy" is Fd. But as distance is the distance applied of the force, we substitude it my the time application of the force, getting E(work done)=Ft

then we can get the power of the object in time-travelling and other characteristics.

The problem with these chains of formulas is that I am substituing distance with time. I'm not sure if the numbers that we obtain would still be valid.

IMO - the measurement of incremental time changes necessitates the complete experimental verification of Einstein's general theory of relativity. Please see the link at http://www.osti.gov/energycitations/...sti_id=5297114

Ronald Mallett from the University of Connecticut... has devised an experiment... to observe a time traveling neutron in a circulating light beam.... While his team still needs funding for the project... Mallett calculates that the possibility of time travel using this method could be verified within a decade... With a brilliant idea and equations based on Einstein’s relativity theories....

Black Holes and Worm Holes + Cosmic Strings... have been proposed as a method for time travel... however none of these are feasible... simply because they require a such large amount of mass... and in gigantic proportions....

Einstein showed that mass and energy were "the same thing"... however Dr Mallet proposes using light... in the form of circulating lasers to warp or loop time instead of using massive objects...

To determine if time loops exist... Mallett is designing a desktop-sized device that will test his time-warping theory.... By arranging mirrors... Mallett can make a circulating light beam which should warp surrounding space.... Because some subatomic particles have extremely short lifetimes... Mallett hopes that he will observe these particles to exist for a longer time than expected when placed in the vicinity of the circulating light beam... A longer lifetime means that the particles must have flowed through a time loop into the future....

Is it TT possible???

[baudrunner]

No.

The fact is that we don't need to bounce "light beams" around in circles to warp space. We all warp space merely by being present in it. We therefore also warp time. Actually, a person who is engaging in very active mental processing warps time more than a sleeping person.

The point is that we are all time travelling all the time but the idea that we can transport ourselves into the future or the past is pure science fiction.

The relative effects of our time travelling as I've explained it are too subtle to apply in any practical sense. As is relativity overall. The effect on time that the onboard atomic clock of an orbiting GPS satellite experiences away from the pull of gravity and travelling at high velocity relative to a stationary one down here on Earth is about thirty eight millionths of a second per day. Mind you, it is enough to my mind that it is measurable, that it proves the theory of relativity to be not theory at all, but fact.

I would not extend Ronald Mallett funding for his experiment if I had any say, however.
