“Whether closed timelike curves exist in reality, we don’t know."

One of the biggest questions in physics asks whether space-time is classical or quantum in nature. From slow neutrinos to quantum foam, these experiments are hoping to finally answer it

Monika Schleier-Smith is testing the idea that space-time emerges, like a hologram, from quantum interactions by attempting to make it in the lab

On November 7, 2006, 12 United employees at O’Hare International Airport in Chicago saw a metallic, saucer-shaped UFO flying in the sky.

The strange craft was spotted by workers at Chicago's O'Hare International Airport flying through the skies above and has left experts baffled as to exactly what it could be

Catch up on some of September’s retail openings and closings below.

An Alcubierre warp drive, craft would benefit from a classic flying saucer-shape, the physicists said. And the warp bubble created could help explain the lack of radar signal

I’ve made mention of this before, but it bears repeating; when I was a little lad growing up in England, it seemed to me that, as soon as two or more adults huddled together, they had only three main topics of conversation. They started with the weather—how it was today, how this compared to the…

Physicists are using quantum computers to conjure various exotic phenomena and are claiming that their creations are truly real. The work is forcing us to ask challenging questions about the nature of quantum reality

Detecting the permanent imprints left by colliding black holes would reveal a universe saturated with infinite symmetries – and narrow the possibilities for a theory of quantum gravity.
