A test using atomic clocks will watch superpositions ride Earth’s curved space-time and see if Einstein can play nice with ...

Air and space superiority is crucial for the U.S. to maintain global stability and effective deterrence, and to ensure the safety and security of the nation, and it is why we must fund ...

The mind-bending concept of time dilation results from a seemingly harmless assumption—that the speed of light is the same for all observers.

Time is one of the most intriguing concepts in physics, and yet, it's something that we often take for granted. But what if the way we experience time moving only forward defies the very laws of ...

One computer scientist’s “stunning” proof is the first progress in 50 years on one of the most famous questions in computer ...

Williams’ proof established a mathematical procedure for transforming any algorithm — no matter what it does — into a form that uses much less space. Ryan Williams stunned his colleagues with a ...

In this paper, the notion of the cumulative time varying graph (C-TVG) is proposed to model the high dynamics and relationships between ordered static graph sequences for space-based information ...

Imagine a swarm of fireflies, flickering lights on and off in the nighttime space. How does the human brain process and integrate information about duration and spatial position enabling this ...
