Few concepts in physics are as familiar, yet as enigmatic, as time. In Einstein's theory of relativity, time is not absolute: ...

When you throw a ball in the air, the equations of classical physics will tell you exactly what path the ball will take as it ...

Time already behaves strangely in modern physics. It can stretch, slow, and split depending on speed and gravity.

Researchers have, for the first time, observed tiny voids in phonon-polariton waves moving faster than light, without violating Einstein’s theory of relativity. Using ultrafast electron microscopy on ...

For over a century, scientists have been intrigued to decode the perplexing scenery behind contemporary physics. It's been up for many years, and yet the experts still have no idea how to bridge the ...

For over 100 years, two theories have shaped our understanding of the universe: quantum mechanics and Einstein’s general relativity. One explains the tiny world of particles; the other describes ...

Scientists previously theorized time can go quantum, using atomic clocks will demonstrate how it can tick fast and slow at ...

Some random article came up on google for me about how there is a new attempt to reconcile both QM and Relativity through some space time dimension field. The point being that wouldn't such a theory ...

Before Einstein, physics looked almost finished. The universe seemed to behave like an excellent Swiss railway timetable. Matter moved. Forces acted. Time ticked away in the background like a reliable ...

Before a beginners’ physics class at St. Louis’ Washington University, Assistant Professor Edward Lambe plugged in an electric device that shot pennies at a metal disk a few feet away. The pennies ...
