There’s an adage coined by [Ian Betteridge] that any headline ending in a question mark can be answered by the word “No”. However, Lorentz invariance – the theory that the same rules of physics apply ...

When an object moves extremely fast—close to the speed of light—certain basic assumptions that we take for granted no longer apply. This is the central consequence of Albert Einstein's special theory ...

Tachyons are hypothetical particles that travel at speeds greater than the speed of light. These superluminal particles, are the "enfant terrible" of modern physics. Until recently, they were ...

The idea was first hypothesized about 70 years ago. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. In a bizarre repercussion of Albert ...

For the first time, physicists have demonstrated a phenomenon known as the Terrell-Penrose effect, which causes an object moving close to the speed of light to warp before our eyes. The new findings, ...

110 years ago today, Albert Einstein published his General Theory of Relativity, which redefined the relationship between matter and gravity. Suddenly, our mysterious universe made a little more sense ...

Albert Einstein is arguably the most influential scientist of the 20th century. His general theory of relativity changed our understanding of space and time, becoming one of the two pillars of modern ...

In his classic science-fiction story “The New Accelerator,” published in 1901, H. G. Wells describes a drug that speeds up a person’s metabolism by a factor of 1,000. For the two protagonists who ...

Tiny “Ferris wheels” made from light and extremely cold particles could allow researchers to test a facet of Albert Einstein’s theory of relativity on unprecedentedly small scales. Theories of special ...
