Scientists prove cosmological speed limit, time travel moves a little further out of reach

The cosmological speed limit remains unbroken. A team of researchers from the Hong Kong University of Science and Technology, led by Du Shengwang, claim to have proven that a single photon is incapable of traveling faster than light. The support for Einstein’s special theory of relativity all but rules out the simplest form of time travel — breaking the universe’s traffic laws to condense time within a vessel. Don’t get freaked out though, this doesn’t mean time travel is impossible, only that it will be much more difficult than firing up a warp drive. General relativity still holds hope for bending and ripping the space-time continuum to meet our eon-hopping desires. Looks like it’s time to get working on our flux capacitor technology.
