For 550 million years, neutral atoms blocked the light made in stars from traveling freely through the Universe. Here's how it then changed.
In pre-War Cambridge, students had to ace an interview with Ludwig Wittgenstein to attend his lectures — Alan Turing passed that test, and went on to create one of his own.
Stem cells from a fetus can live within the mother for decades — and help her heal.
Visionaries from Socrates to Steve Jobs have touted curiosity as an essential quality. Here’s how to supercharge your spirit of inquiry.
Two of the answers add a dimension to physics that doesn’t belong there. Maybe we could call it "astrotheology."
When we look at our Sun, its properties are incredibly constant, varying by merely ~0.1% over time. But all stars don't play by those rules.
From ancient Greek cosmology to today's mysteries of dark matter and dark energy, explore the relentless quest to understand the Universe's invisible forces.
2023's Nobel Prize was awarded for studying physics on tiny, attosecond-level timescales. Too bad that particle physics happens even faster.
The perfectly accessible, perfectly knowable Universe of classical physics is gone forever, no matter what interpretation you choose.
If nature were perfectly deterministic, atoms would almost instantly all collapse. Here's how Heisenberg uncertainty saves the atom.
Science and technology were making early modern Europe a better place to live, but at what cost?
How can you maximize the amount of love and happiness in your life? One of history's greatest scientists found the answer: with math.
Neutrons can be stable when bound into an atomic nucleus, but free neutrons decay away in mere minutes. So how are neutron stars stable?
To this day, one cult believes that Lemuria was real, and that its people left us the sacred wisdom to revive their advanced civilization.
A new book envisions an encounter of minds between the Argentinian writer Jorge Luis Borges, the physicist Werner Heisenberg, and the philosopher Immanuel Kant.
American students are being compelled to specialize earlier and earlier. Here's what it takes to build a successful physics foundation.
Never mind.
The polymath used science to elevate his art.
The "Ring Nebula," known for almost 250 years, is so much more than a Ring. With JWST's capabilities, we're seeing more than ever before.
By probing the Universe on atomic scales and smaller, we can reveal the entirety of the Standard Model, and with it, the quantum Universe.
The visible Universe extends 46.1 billion light-years from us, while we've probed scales down to as small as ~10^-19 meters.
Is LK-99 truly a room temperature superconductor? These 4 tests, none of which have yet been passed, will separate fact from fiction.
An X-ray offers a glimpse into the painter’s early years.
We may be the last generation born not knowing if we are alone in the Universe.
For many years, cosmologists have claimed the Universe is 13.8 billion years old. A new paper says no, it's 26.7 billion. How do we decide?
As cells divide, they must copy all of their chromosomes once and only once, or chaos would ensue. How do they do it? Key controls happen well before replication even starts.
Perhaps there was something theatrically satisfying about a learned man waving around a flask of pee, looking at it from all angles, sniffing it, and making bold proclamations.
