Einstein's most famous equation is E = mc², which describes the rest mass energy inherent to particles. But motion matters for energy, too.

Your old-fashioned chronological age is just a number. Your biological age can tell you how healthy you really are.
The combination of charge conjugation, parity, and time-reversal symmetry is known as CPT. And it must never be broken. Ever.
We think of physical reality as what objectively exists, independent of any observer. But relativity and quantum physics say otherwise.
Neural imaging has shown that the brain has “decided” what we’re going to do before we make a conscious choice — but is this even relevant to free will?
Ever since the start of the hot Big Bang, time ticks forward as the Universe expands. But could time ever run backward, instead?
Proponents of transhumanism make big promises, such as a future in which we upload our minds into a supercomputer. But there is a fatal flaw in this argument: reductionism.
Do the health risks outweigh the benefits?
Even after the first stars form, those overdense regions gravitationally attract matter and also merge. Here's how they grow into galaxies.
We live in a four-dimensional Universe, where matter and energy curve the fabric of spacetime. But time sure is different from space!
"Spanish Stonehenge" contains 526 giant stones, three circular burial sites, a quarry, and four necropolises.
Individual space telescopes, like Hubble and JWST, revolutionized our knowledge of the Universe. What if we had an array of them, instead?
Symmetries aren't just about folding or rotating a piece of paper, but have a profound array of applications when it comes to physics.
Biological age is a better health indicator than the number of years you’ve lived, but it’s tricky to measure.
A combination of factors make the weather at New Hampshire's Mount Washington arguably the most brutal in the world.
Seventy-five years after the anomaly's discovery, scientists have finally figured out why sea levels are so much lower here.
Our temporal experience of the world is not divided into a series of neat segments, yet that's how we talk about time.
Grandmasters and drug dealers have one thing in common: They are many steps ahead of their rivals.
After 15 years of monitoring 68 objects known as millisecond pulsars, we've found the Universe's background gravitational wave signal!
Considering the astronomical occupational risks, life insurance was prohibitively expensive for the first NASA astronauts.
Is mindfulness really the panacea it's touted to be, or are we glossing over some fundamental flaws?
Ultracold gases in the lab could help scientists better understand the universe.
This article was originally published on our sister site, Freethink. Fifteen volunteers in France just spent more than a month living in a cave — without any way to tell time — […]
Wealthier in resources; poorer in time.
In 1924, sociologist and social reformer Caroline Bartlett Crane designed an award-winning tiny home in Kalamazoo, Michigan.
How to say “I love you” in Basque, the "most loving" cities around the world, and where most of America’s singles live — and so much more!
Setting resolutions for the new year means you think the future is up to you — but is it?
Particles are everywhere, including particles from space that stream through the human body. Here's how they prove Einstein's relativity.
Piano Sonata No. 23 offers a window into the way culture became an instrument of Soviet state policy.
