Our universe plays by certain rules, which originate from different branches of physics. But sometimes the rules seem ...

Physicists have struggled to understand the nature of time since the field began. But a new theoretical study suggests time could be an illusion woven at the quantum level. When you purchase through ...

A new definition of time suggests that what we once thought was a fundamental element of our physical reality could actually just be an illusion created by quantum entanglement. That's a very bold ...

For the second time in as many months, images gathered by the Hubble Space Telescope (HST) are raising questions about the structures of time and gravity, and the fabric of space. Using two HST images ...

It was already a mind-bending shift, last century, to go from Isaac Newton’s absolute space and universal time to Albert Einstein’s four-dimensional space-time, which is dynamic, flexible, sensitive ...

“This retroactive idea. It has to be that,” says Nobel Prize-winning mathematical physicist Sir Roger Penrose, reflecting on a problem about the building blocks of reality that has dogged physics for ...
