A trippy fringe theory suggests that time is the source of all physical matter, and space is merely a byproduct.

For decades, he hid his time-travel obsession. Now, he is challenging the assumptions that underpin our universe.

Albert Einstein's theory of general relativity—which explains gravity as the product of the distortion of space and time—may not be universally applicable. This is the conclusion of physicists ...

“The chief attraction of the theory lies in its logical completeness,” wrote Albert Einstein after publishing his general theory of relativity in 1915. “If a single one of the conclusions ...

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 ...
