Time Trave Impossible: Blame It On The Photons

Sorry scifi nerds, looks like the Tardis is just an old call box after all.

Science fiction will never be the same again. Apparently time travel has now been proven to be impossible and it's all thanks to those little balls of light, photons.

The prospect of time travel seems unlikely, according to the latest findings by physicists who confirmed the ultimate speed limit of photons, which are packets of light.

The universe's ultimate speed limit is the speed of light in a vaccum. Recent experiments suggested that single photons might beat it and allow for the prospect of time travel, but now findings indicate that individual photons are also limited to the vacuum speed limit.

Einstein's theory of special relativity maintains that an event's effect cannot precede its cause by traveling faster than light. A violation of this causality would permit time travel.

The limit in a vacuum is a fixed number - about 300,00km per second, but the speed of light can vary.

"By showing that single photons cannot travel faster than the speed of light, our results bring closure to the debate on the true speed of information carried by a single photon," said professor Shengwang Du of Hong Kong University of Science and Technology.

In conclusion, photons cannot time travel, and moving information around at faster-than-light speeds is not possible. But that doesn't mean that time travel is entirely ruled out.

Ok, so it's not ruled out. It just means that it's impossible if you are made of matter. So, now all we have to do is figure out how to turn matter into anti-matter or harness the energy of a star, find a black hole, if they exist, toss ourselves in and use that harnessed energy to propel us into another time and space hoping that DS9, Stargate and Sliders got it right.
