Quote of the day by Newton: 1915 changed physics forever. In that year, Albert Einstein published the general theory of relativity and reshaped our understanding of gravity and spacetime. For 228 ...

Physicists have long struggled to unite quantum mechanics—the theory governing tiny particles—with Einstein’s theory of ...

A newly derived “q-desic” equation suggests that quantum effects may subtly alter particle trajectories across the universe.

A unified Theory Of Everything is the holy grail of physics, but gravity refuses to play ball. Now, a newly proposed theory attempts to unify Einstein’s theory of gravity with quantum mechanics – and ...

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 ...

If gravity arises from entropy, scientists could unite Einstein's general relativity with the quantum realm while shedding light on dark matter and dark energy. When you purchase through links on our ...

Susskind, a physics professor at Stanford, and Cabannas, a former MIT math professor, offer an overview of Einstein’s theory of general relativity in this survey for specialists, the fourth volume of ...

It feels so obvious that time moves forward that questioning it can seem almost pointless.

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 ...
