Possible Solution to Einstein's Gravitational Field Equation

[Kraelis]

I saw this article and decided to do a quick check here to see if it's been posted. Since I didn't see it, I'm posting it here for the benefit of the more scientifically inclined.

I also intentionally used a formal title instead of what it really implies to avoid the hype.

I'll just be popping in and out. See ya guys!

An interesting read, thanks for that Kraelis.
It just shows that we are getting closer to travelling faster than the speed of light, therefore travelling back in time

Ahhhh, but I have been reading that time travel is impossible! I will try to explain this as I read: Velocity in space, v, is represented as v = dx/dt; that is position is position in respect to time. Velocity in time would be impossible, because it would be dt/dt, and any calculus student would be able to tell you that the answer is 1, therefore there is only one time, now.

Bookmarked. Will report my opinion (much) later. Thanks Kraelis.

.. From a glimpse at the article, I'm puzzled at how you came to the idea of 'travelling faster than the speed of light', while being twice as puzzled at the conclusion that past time could be recovered through such endeavors (if at all).

Let's get just one thing straight here: We have no influence on time whatsoever; it's just a concept in our minds to represent what has been, what is, and what will be. Anyone trying to convince me that speed of motion could realistically alter anything like time, will have a hard time. Shatter my world, will you?

I find it interesting that at the link there are people saying his theory is wrong... despite the fact none of them are even close to being qualified for giving a valid point of view on this.

As for turning back time, its really hard to say for sure if it is possible or not, although I imagine certain people will be adamant on their opinions. At this point we can only say 'why not?' as the new scientific findings of leading scientists turn our conventional justified-by-the-unjustifiable beliefs upside down.

Funny world, ain't it.

I saw this a few weeks ago at a transhumanist mail-list. I must confess that I'm not that impressed. Of course I lack the technical background to rigorously disprove such a claim, but I’m usually wary around big claims, especially when they involve controversial aspects of a theory.

But I wouldn’t oppose funding such an endeavor, depending on its cost, because the solution is not prima facie implausible. Experiments are the best way to prove the validity of his solution.

There is nothing in science that rules out the possibility of time travel. 100 years ago who would have though we would be able to speak to someone on the other side of the world through 'invisible' waves. Never say never.
Yes time is just sumthing we percept but its not about the time, its about light and what we see.

While I'd tend to support such a thing, I remain skeptical. I'll wait and see if the papers survive after being presented. I doubt it, though. They didn't convince me.

very much agreed. there is no time, only change.

Light and bending time are very closely related subjects. Did you know that light travels at different speeds through different materials? In some materials light moves as slowly as the average walking speed of a person. As a person approaches the speed of light one adapts certain properties of light. If your monecules are moving so fast then you experience time on a different level and 3 weeks could be 10 years to the rest of the world. All this has already been proven, but after this point it starts getting to theory. Think of the speed of light as zero for a second. Now everything below zero represents time moving forward, at whatever speed. But whats on the other side of zero? One would think that time moves the other way. Its certainly interesting to say the least.

I gotta go, I'll type the rest later .

Speaking of time and space, we've seen some preliminary evidence towards the hypothesis that time and space could be a kind of fluid, made up of individual particles. See, for instance, What did we learn from studying acoustic black holes?

The above paper is rather technical so I suggest taking a look at the last December issue of Scientific American magazine.
