Thanks to Einstein’s relativity, time flows differently on Mars than on Earth. NIST scientists have now nailed down the difference, showing that Mars clocks tick slightly faster—and fluctuate over the ...

Is time real, or an illusion? The best answer may be neither: Both physics and philosophy suggest that time is a projection of the mind onto a timeless reality. When you purchase through links on our ...

If gravity arises from entropy, scientists could unite Einstein's general relativity with the quantum realm while shedding light on dark matter and dark energy. When you purchase through links on our ...
