Thanks to Einstein’s relativity, time flows differently on Mars than on Earth. NIST scientists have now nailed down the ...

Time really does move faster on Mars, but the breakthrough that confirms it did not come from a spacecraft’s stopwatch.

Time travel has shifted from pure fantasy to a serious, if highly constrained, topic in modern physics. The equations that ...

Besides quantum mechanics, another interesting topic in physics is relativity. Let’s take a look at it! Of all the force fields, the gravitational field is the one man has known for the longest time.

Yesterday, I wrote about the core concepts needed to understand quantum physics, which is one of the two pillars of modern physics. The other, of course, is the theory of relativity, the full and ...

Physicists from JILA — a CU Boulder and National Institute of Standards and Technology institute — were able to measure an effect called time dilation at the smallest scale ever, which they say could ...

Among the oft-repeated predictions of Albert Einstein's famous theory of relativity is that if a twin travels through the cosmos on a high-speed rocket, when he returns to Earth he will be noticeably ...

As you read this sentence, you probably think that this moment—right now—is what is happening. The present moment feels special. It is real. However much you may remember the past or anticipate the ...

A time warp can be thought of as anything that disrupts the flow of time by making it go faster or slower. While the idea may seem fantastical, time warps were predicted by Albert Einstein's ...
