Science cannot help us understand or describe first-person experience. Zen koans are a powerful form for helping us reach that description.
Almost 100 years ago, an asymmetric pathology led Dirac to postulate the positron. A similar pathology could lead us to supersymmetry.
The concept of ‘relativistic mass’ has been around almost as long as relativity has. But is it a reasonable way to make sense of things?
For every proton, there were over a billion others that annihilated away with an antimatter counterpart. So where did all that energy go?
Our greatest tool for exploring the world inside atoms and molecules, and specifically electron transitions, just won 2023’s Nobel Prize.
The quantum world — and its inherent uncertainty — defies our ability to describe it in words.
Carrie Berk reveals how she transformed her struggle with anxiety and internet fame by changing her perception and finding her true voice as a writer.

The Universe is expanding, and the Hubble constant tells us how fast. But how can it be a constant if the expansion is accelerating?
Successful alpha leadership is more about caring and healing than dog-eat-dog supremacy.
From forming bound states to normal scattering, many possibilities abound for matter-antimatter interactions. So why do they annihilate?
The science fiction dream of a traversable wormhole is no closer to reality, despite a quantum computer’s suggestive simulation.
The quantum world is one in which rules that are completely foreign to our everyday experience dictate bizarre behavior.
From the tiniest subatomic scales to the grandest cosmic ones, solving any of these puzzles could unlock our understanding of the Universe.
Light carries with it the secrets of reality in ways we cannot completely understand.
There are a wide variety of theoretical studies that call our Standard Model of cosmology into question. Here’s what they really mean.
This is especially true for three key groups.
Most of us only ever see a fraction of a full rainbow: an arc. But optically, a full rainbow makes a complete circle. Physics explains why.
Whenever someone waxes poetic about terraforming alien worlds, it’s worth taking a moment to consider the ethical implications of the proposal.
A group of prominent scientists shares how research has changed them.
Whether you’re a leader looking to ramp up team output or just trying to improve your skill set, hard work alone is not enough.
Tumor cells traverse many different types of fluids as they travel through the body.
Traveling back in time is a staple of science fiction movies. But according to Einstein, it’s a physical possibility that’s truly allowed.
All the things that surround and compose us didn’t always exist. But describing their origin depends on what ‘nothing’ means.
Dive into a realm where time, space, and even reality itself are put into question.
Singularities frustrate our understanding. But behind every singularity in physics hides a secret door to a new understanding of the world.
There’s a quantum limit to how precisely anything can be measured. By squeezing light, LIGO has now surpassed all previous limitations.
For centuries, Newton’s inverse square law of gravity worked beautifully, but no one knew why. Here’s how Einstein finally explained it.
There are a few clues that the Universe isn’t completely adding up. Even so, the standard model of cosmology holds up stronger than ever.
The farther away they get, the smaller distant galaxies look. But only up to a point, and beyond that, they appear larger again. Here’s how.
