Нашёл у kasuku этот пост, выжимку из этой новости - http://www.moreideas.net/2015/12/08/physicists-send-particles-of-light-into-the-past-proving-time-travel-is-possible/.

Там на английском, но вкратце - учёные из университета в Австралии заставили фотон отправиться в прошлое. Кроме того, ещё в 2007 году (я не знал, честно!) учёные из Франции смогли пост-фактум повлиять на уже случившееся. Вот это новости.

Scientists from the University of Queensland, Australia, have used single particles of light (photons) to simulate quantum particles travelling through time.

They showed that one photon can pass through a wormhole and then interact with its older self. Their findings were published in Nature Communications.

In 2007 (Science 315, 966, 2007), scientists in France shot photons into an apparatus and showed that their actions could retroactively change something which had already happened.
This particular experiment illustrates how what happens in the present can change what happened in the past. It also shows how time can go backwards, how cause and effect can be reversed, and how the future caused the past.

Why these same quantum mechanical laws have not been observed on the macroscopic level is yet to be understood, but physicists are working on the problem. For example, in 2012 physicists David Wineland and Serge Haroche received the Nobel Prize in physics for demonstrating how “quantum weirdness” could not only exist at the subatomic micro-world level, but also show itself in the macro-world. At one time, superposition was only thought to exist in the inaccessible quantum world, but not anymore. We know it’s possible, we just haven’t figured out how. We do, however, seem to be getting closer to finding out.
