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

Quantum mechanics and relativity are the two pillars of modern physics. However, for over a century, their treatment of space ...

Physicists have long treated space and time as the stage on which quantum particles perform, not as actors in the drama ...

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works ...

The entangled clocks can test how quantum theory behaves in the presence of curved space-time as predicted by Einstein, or whether our current theories break down. Hoboken, N.J., July 14, 2025 — ...

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 and the latter a point in space, but in both cases the normally ...

Most of today’s leading theoretical physicists have a shared perspective about what the next revolution in physics will look like. They think reconciling Albert Einstein’s general theory of relativity ...

Albert Einstein’s theory of gravity, general relativity, is famously incomplete. As proven by physics Nobel laureate Roger Penrose, when matter collapses under its own gravitational pull, the result ...

"The singularity is the most mysterious and problematic part of a black hole. It's where our concepts of space and time literally no longer make sense." When you purchase through links on our site, we ...
