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

For those who watch gravitational waves roll in from the universe, GW250114 is a big one. It's the clearest gravitational ...

Albert Einstein won the 1921 Nobel Prize in Physics, but not for relativity—the theory that made him famous. This article ...

Scientists could soon test Einstein's theory of general relativity by measuring the distortion of time. General relativity states that gravity is the result of mass warping the fabric of space and ...

In 1905, Albert Einstein revolutionized physics by demonstrating that time is not absolute but relative to the observer's ...

Albert Einstein had described the special theory of relativity in 1905. The result of Einstein's thinking about light, this theory introduced brand-new ideas to science. It opened up an entire field ...

The way time ticks forward in our universe has long stumped physicists. Now, a new set of tools from entangled atoms to black ...

We experience the flow of time because it’s a natural outcome of the basic laws of physics. But we may need to build a whole ...

Time feels like the most basic feature of reality. Seconds tick, days pass and everything from planetary motion to human memory seems to unfold along a single, irreversible direction. We are born and ...

As 24-cent copies of Albert Einstein’s abstruse “Coherent Field Theory” reached the U. S. last week, the man himself, his wife and a daughter plodded about Wannsee, simply hunting rooms at that lake ...
