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

What is space-time? Depending on how fast you're moving or how close you are to Earth's gravity can change the way time feels.

An ambitious new fleet of spacecraft could reveal whether space-time is smooth or chunky, and in doing so the ultimate nature of reality.

Is space-time ultimately smooth at the tiniest of scales, or something else? It seems impossible to measure, but researchers are beginning to look down. Deep down.

“Using newer mathematical tools, my colleague and I have demonstrated a new theory that may accurately describe the universe. Instead of basing the theory on the warping of space and time, we ...

Ever since Einstein showed that gravity is the result of the curvature of space and time by a massive object, scientists have freely talked about space/time as some sort of fabric. But the very ...

An ambitious new fleet of spacecraft could reveal whether space-time is smooth or chunky, and in doing so the ultimate nature of reality.

Natalie Paquette spends her time thinking about how to grow an extra dimension. Start with little circles, scattered across every point in space and time—a curlicue dimension, looped back onto ...
