Everyone knows Albert Einstein was a genius, but can you explain what he’s famous for? Arguably his foremost theory, his general theory of relativity, turns 100 years old this week. It was actually ...

In many universes, typically those on TV shows or in movies, time travel is not much more difficult than driving downtown in any major city during rush hour. Sure, the traffic can get gnarly, but no ...

Time might actually have 3 dimensions. But it also means that the space would actually be one-dimensional, instead of the three dimensions we’re familiar with. This way of looking at the cosmos could ...

To put it simply, the block universe theory is an inevitable byproduct that emerged as a result of the theory of relativity ...

Albert Einstein's general theory of relativity describes how the fabric of space and time, or spacetime, is curved in response to mass. Our sun, for example, warps space around us such that planet ...

This image of Europe’s Columbus space laboratory was taken by ESA astronaut Luca Parmitano during his spacewalk on July 9, 2013. Image via ESA/NASA. The International Space Station will host the most ...

When he unveiled his general theory of relativity, Albert Einstein wasn’t exactly met with applause. Almost no one else could do the math necessary to understand his abstract ideas, and at the time he ...

Most of us don’t hear a whale call and think, ‘Wow, look at the special theory of relativity in action.’” Tachyons are a hypothetical particle generally thought to be incongruous with Einstein's ...

In 1915, Albert Einstein put forth a new theory of gravity: General Relativity. Instead of every mass in the Universe instantly reaching across to every other mass and exerting an attractive force, ...

Albert Einstein's theory of relativity is actually two separate theories: his special theory of relativity, postulated in the 1905 paper, The Electrodynamics of Moving Bodies and his theory of general ...

Differences in perspective② Breakdown of calculations (Occurrence of infinity)3. In what situations does this cause ...

The International Space Station will host the most precise clocks ever to leave Earth. Accurate to a second in 300 million years the clocks will push the measurement of time to test the limits of the ...
