Scientists are developing theoretical models for faster-than-light travel, inspired by Star Trek's warp drive, making interstellar journeys theoretically possible.

Scientists at TU Wien have uncovered that quantum correlations can stabilize time crystals—structures that oscillate in time ...

This Star Trek concept ignited a dream that humans could one day travel faster than the speed of light. Now physicists are ...

For the first time, physicists have simulated what objects moving near the speed of light would look like — an optical ...

High above the Sun’s blazing equator lie its mysterious poles, the birthplace of fast solar winds and the heart of its ...

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 ...
