In 1922, Albert Einstein explained how to live a happy life to a bellboy in Tokyo.

The result validate Einstein on a whole new scale, and pose serious problems for alternative, modified theories of gravity. In 1915, Albert Einstein put forth a new theory of gravity: General […]

A debate over the physics of time in an alleged “block universe.”

New research on the hypothalamus shows that body heat matters.

During the second string revolution, in 1995, physicists proposed that the five consistent string theories are actually only different faces of a unique theory.

Really puts the whole “don’t give up until you’re dead” thing to shame.

Cosmologists behind braneworld theories see our universe as being a part of a complex inter-dimensional world.

We don’t have to stop inquiring or wondering about the far-flung vistas of reality, we just need to do it with some good old-fashioned logic.

Albert Einstein’s famous thought experiments led to groundbreaking ideas.

Here are four great brains from great minds, and how they differ from yours.  

“The value of a college education is not the learning of many facts but the training of the mind to think,” Albert Einstein said. So go back to school, Ivy League style.

In 1936, a school girl named Phyllis wrote a letter to Albert Einstein to ask whether a person could believe in both science and religion. He was quick to reply.

Before Hawking, black holes were just static points in the background of space. His greatest scientific legacy taught us just how dynamic they are. In 1915, Albert Einstein published his General […]

Hitler and other Nazis were fond of a strange theory that the world was made of ice.

It’s so much more than mass-energy equivalence; it’s the key to unlocking the quantum Universe. For hundreds of years, there was an immutable law of physics that was never challenged: […]

There’s a big reason no one, not even Stephen Hawking, could fill Carl Sagan’s shoes. Everyone has a unique story to tell. For scientists, that story is one that usually only […]

What if entanglement also occurs across time? Is there such a thing as temporal nonlocality?  

Physicists make a new discovery in quantum mechanics, showing nanomagnets can levitate despite a classic theorem that said it’s impossible.

Scientists are supposed to reach their conclusions after doing research and weighing the evidence but, in economics, conclusions can come first, with economists supporting a thesis that fits their moral worldview.  

Einstein believed in the unseen—like gravitational waves, ripples in space and time. Now, we can see this, as shown by the 2017 Nobel Prize physics winners.

The idea is just as ‘crazy’ as Einstein telling us that time slows down at high speeds, or Darwin saying that our ancestors were apes.    

Another week, another thrilling installment of our Comment of the Week feature with handpicked favorites from our Facebook page. 

Astronomers make the first direct observation of a phenomenon predicted by Albert Einstein’s theory of general relativity.

If not for the indeterminate nature of matter, the Sun would never be able to shine. “The bedrock nature of space and time and the unification of cosmos and quantum are […]

Did you make the cut? 

Cosmic collision yields bullion by the billions.

Many organizations look for ways to improve their employee learning and development programs in the new year. One solution with proven results is self-directed learning.Self-directed learning, or SDL, is a process […]

The secret behind the Em Drive’s thrust, which is real, may be in the long-discarded pilot wave theory.

These scientists scooped up the Nobel by detecting a ripple in space-time.

Scientists discover a counterintuitive property of quantum particles called “backflow”.
