Time travel has shifted from pure fantasy to a serious, if highly constrained, topic in modern physics. The equations that describe gravity, quantum fields and the structure of spacetime now allow ...

What near light-speed travel would do to time, mass and distance?
A spacecraft traveling at 99 percent the speed of light toward Alpha Centauri would cross 4.3 light-years in what feels like ...
Last week, we touched upon E=mc2, and how Einstein’s theory of relativity turned the world of physics upside-down. Now, we’re using that theory to show why the very concept of time may not be what you ...
What if the flow of time isn’t as one-way as it seems? Researchers from the University of Surrey have uncovered evidence that in the strange world of quantum physics, time could theoretically run both ...
Stephen has degrees in science (Physics major) and arts (English Literature and the History and Philosophy of Science), as well as a Graduate Diploma in Science Communication. Stephen has degrees in ...
Time, not space plus time, might be the single fundamental property in which all physical phenomena occur, according to a new theory by a University of Alaska Fairbanks scientist. The theory also ...
Add Yahoo as a preferred source to see more of our stories on Google. Time is a fickle thing. Depending on your frame of reference, it can appear to pass slower or quicker, thanks to a wonky ...
Time feels like the most basic feature of reality. Seconds tick, days pass and everything from planetary motion to human memory seems to unfold along a single, irreversible direction. We are born and ...
Time is not to be trusted. This should come as news to no one. Yet recent times have left people feeling betrayed that the reliable metronome laying down the beat of their lives has, in a word, gone ...
In a first, astronomers have observed time ticking in slow motion in the early cosmos, confirming Albert Einstein’s century-old ideas about the reality-warping effects of our universe’s expansion. By ...
Time is a fickle thing. Depending on your frame of reference, it can appear to pass slower or quicker, thanks to a wonky phenomenon known as time dilation that was described in Albert Einstein’s ...
