How Einstein tried to model the shape of the Universe

In 1917, just two years after Albert Einstein proposed the general theory of relativity — his revolutionary new theory of gravity — he took a bold step forward and decided to apply his theory to the Universe as a whole. His question was simple but …

Scientists Defy Physics, Basically Pull Energy Out of Thin Air

Energy teleportation sounds like the stuff of science fiction, but now, research shows that you can actually pull energy from nothing. Using quantum mechanics, two different physics experiments prove it’s possible to conjure energy from an energ…

Scientists Figured Out How to See the Beginning of Time

Princeton scientists believe they have the tools to peer back into the beginning of time itself. The researchers say they can use ripples in space-time, known as gravitational waves, to basically see the start of everything we know. “We can’t se…

Not just light: Everything is a wave, including you

In 1905, the 26-year-old Albert Einstein proposed something quite outrageous: that light could be both wave or particle. This idea is just as weird as it sounds. How could something be two things that are so different? A particle is small and confi…

This is the most accurate image of an atom

A mysterious quantum phenomenon reveals an image of an atom like never before. You can even see the difference between protons and neutrons. The Relativistic Heavy Ion Accelerator (RHIC), from the Brookhaven Laboratory in the United States, is a…

Mathematics Does Not Prohibit Traveling Back in Time

What more exciting possibility does physics raise than time travel? We all dreamed of an opportunity to visit the Triassic or repeat an exam in “ the DeLorean .” Of all the paradoxes that our interpretation of physical phenomena brings us, probably…

An Extreme Black Hole Collision Just Proved Einstein Was Right

The Theory of Relativity, published in 1905 by Albert Einstein, postulated the existence of gravitational waves—oscillations of the space-time fabric—and more than a century later, we have irrefutable evidence of it. Now, a new study has managed to…
