For more than a century, modern physics has rested on two towering frameworks that do not quite agree with each other.

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

Time may not be a fundamental element of the universe but rather an illusion emerging from quantum entanglement, a new study suggests. Time is a thorny problem for physicists; its inconsistent ...

A study by physicists affiliated with the Foundational Questions Institute (FQxI) found that time ...

In an effort to bring together the domains of gravity and quantum theory, Albert Einstein and Nathan Rosen proposed a ...

Quantum physics overturned classical ideas by showing that matter behaves very differently at the ...

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 ...

Physicists have proposed a new model of space-time that may provide the 'first observational evidence supporting string theory,' a new preprint suggests. When you purchase through links on our site, ...

Wormholes are often imagined as tunnels through space or time—shortcuts across the universe. But this image rests on a ...

The original version of this story appeared in Quanta Magazine. Two blind spots torture physicists: the birth of the universe and the center of a black hole. The former may feel like a moment in time ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

Physicists have struggled to understand the nature of time since the field began. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Time may not be ...
