For centuries, we’ve believed time moves in one direction - from the past, through the present, into the future. But new theories in physics suggest that’s not how the universe actually works. Some ...
Meanwhile, your entire existence (and the existence of any object) can be plotted on what’s called a world line, a curving path through spacetime starting at your birth and ending at your death. A ...
Time’s passage is non-negotiable. Its flow marks the progress of our lives, moving clearly in one direction. It is, by nature, asymmetrical. In this way, we perceive it to move like an arrow, ...
Endgame" speaks about the elements of the movie's time-travel plot line that are supported by science.
What if time is not as fixed as we thought? Imagine that instead of flowing in one direction—from past to future—time could flow forward or backwards due to processes taking place at the quantum level ...
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 ...
What does the passage of time look like for a truly quantum object? The world’s best clocks may soon be able to answer this question, testing how time can stretch and shift in the quantum realm and ...
