Paleoacoustics
Eavesdropping on the Past. We can listen to FDR speak of the day of infamy but we can't listen to Lincolns Gettysburg address, it wasn't recorded. However, a branch of theoretical science or pseudo-science as some prefer to call it, paleoacoustics, argues that we may someday be able to hear Lincolns Gettysburg address or even hear Julius Cesar utter Et Tu Brutus, because it may have conceivably been recorded by natural means which we do not fully comprehend. ...

Iranian Time Machine
Time machine uses "complex algorithms" to forsee the future.. Michael Kwok, who applied for a time machine patent in 2008 had an idea akin to Razeqis, but on a whole 'nutter' level. Kwok submitted his plans for an artificial intelligence robotic net - sharing one massive electronic brain. They would have the ability to monitor the position of matter in time and space. The robots in his proposal would use atom manipulators to strategically arrange and re-arrange objects along a perpetually monitored timeline. ... Read More

... The last contact with the researchers gleaned from institute records was as follows ... "We are dying but keep on conducting the experiment. It is very dark here; we see all objects become double, our hands and legs are transparent, we can see veins and bones through the skin.

Perfecting our Time Travel Capabilities
As we advance through the chronological illusion of time on a societal basis we are learning that time travel may not be a fantasy at all, but could actually be possible and may have already been perpetrated. In fact you can leave out the "May Have" fragment of the last sentence because we already have a time machine, it just needs to be tweaked a tad ... okay ... a few tads more than a tad. And it is not a super secretive cloak and dagger Government conspiracy. It's right in our face for those who wish to delve into the topic. ... Read More
Traveling back in time is a staple of science fiction movies. But according to Einstein, it’s a physical possibility that’s truly allowed.
By Ethan Siegel
When you think about the idea of time travel, you likely think about the fantastic possibility of going backward in time to an event in the past, rather than our constant, inevitable march forward in time. After all, traveling back in time remains one of the greatest tropes in movies, literature, and television shows: the idea that we could do so in a fashion that lets us alter the past, correcting “mistakes” that were made by ourselves or by others. From the time turner in Harry Potter to a Delorean at 88 miles-per-hour in Back To The Future to the countless time loops experienced by the protagonist in Groundhog Day, traveling back in time provides us with the possibility of righting wrongs that have already occurred in the past
To most people, it’s an idea that’s relegated to the realm of fiction, as every law of physics indicates that the only way we’re allowed to move through time is forward. Philosophically, there’s also a famous paradox that seems to indicate the absurdity of anyone being able to travel arbitrary amounts of time backward: the Grandfather Paradox. Put simply, if traveling backward through time were possible, you’d be able to go back and kill your grandfather before your parents were ever conceived, rendering your own existence impossible. For a long time, backward time travel seemed to be forbidden. But thanks to some very interesting properties of space and time in Einstein’s general relativity, traveling back in time is now known to be physically possible after all.
According to Einstein, space and time are not separate, absolute entities, but rather are woven together in an inseparable fabric: spacetime. There’s a quantity that’s known to be invariant — the spacetime interval (sometimes called the Einstein interval) — that represents your combined motion through space and time together. Put simply: if you’re at rest, and your spatial position doesn’t change, then you’re moving through time at the maximum allowable rate: forward, at a rate of one second-per-second. However, if you’re in motion, and your spatial position does change with time, then you move through time at a slower rate, as objects in relative motion experience the phenomenon of time dilation.
The faster you move through space, the slower you move through time, up to the absolute limit of how fast it’s possible to travel: the speed of light. As you approach that ultimate limit, your motion through space gets faster and faster, while your motion through time gets slower and slower. If you could actually reach the speed of light, which is a physical impossibility unless you’re a massless entity, you’d find that time appeared to stop for you, and wouldn’t pass at all during your journey. In theory, if you could move faster than the speed of light, you’d become a tachyon, and would indeed experience time running backward; however, this possibility is an unphysical situation, as tachyons do not correspond to anything that exists in physical reality.
However, going faster than the speed of light — which is arguably how Superman travels back in time in the original Superman movie — isn’t the only way to travel backward in time, according to Einstein. While the motion of any real entities through the fabric of spacetime is limited by the speed of light in a vacuum, spacetime itself is not required to be flat and unchanging: like a three-dimensional Cartesian grid. Instead, according to Einstein’s general relativity, it’s possible that space can evolve, and as part of that evolution, it can be curved, can expand or contract, or could even create and maintain a connection between two disparate points within it. ...
