First, I’ll give you the opening of a press release from the Hong Kong University of Science and Technology:
A group of physicists at the Hong Kong University of Science and Technology (HKUST) led by Prof Shengwang Du reported the direct observation of optical precursor of a single photon and proved that single photons cannot travel faster than the speed of light in vacuum. HKUST’s study reaffirms Einstein’s theory that nothing travels faster than light and closes a decade-long debate about the speed of a single photon.
You know what that means, right? No time travel. Time travel, they’re saying, is impossible. The study was a response to scientists’ discovery of what seemed to be optical pulses traveling faster than the speed of light, which proved to be a optical illusion, but got them thinking that it could happen, that we could someday go back and forth in time. But, according to this release, it can’t.
No TARDIS? No Doc Brown DeLorean? No San Dimas phone booth? Yes, time travel is a staple of nerd culture, from Star Trek to, well, everything. Are you ready to give up on the idea that time travel is possible? Is the Hong Kong report going to kill off your dreams? Debate in the comments below. And if you’re here from the future… hey, any hot investment tips?
