Time travel has long been a subject of fascination in science fiction, but recent scientific endeavors suggest that it might ...

Few ideas in modern science have reshaped our understanding of reality more profoundly than space-time—the interwoven fabric ...

Here are some potential ways we could travel amongst the stars, ranked from least to most likely. Incredibly unlikely: Faster-than-light travel You can never travel faster than the speed of light.

By combining general relativity, quantum mechanics, and thermodynamics, the study demonstrates that time travel might be feasible without leading to these logical contradictions.

However, physicist John D. Norton has developed a new model based on Einstein's theory of general relativity that shows time travel is mathematically possible.

Mallett specializes in Einstein's general theory of relativity and has published many papers on black holes and cosmology. His research on time travel has gained significant media attention, appearing ...

Two Colorado-based researchers proposed a solution in a recently published scientific paper involving clocks floating in space to calculate the time difference between the Earth and the Moon.

In the gloomy days of January, time seems to drag. According to the Einstein theory of relativity, it actually does—in a minute amount that means little to anyone except a scientist. During its ...
