“You’re not meant to understand what I just said, because I don’t understand what I just said…” Physicist Brian Cox on one of the most complex theories in space science.
Here's the case for why science can't keep ignoring human experience.
The $21.5-billion project could involve tunneling hundreds of feet under Lake Geneva.
Recent measurements of CERN data seem to disagree with standard-model predictions about how the Higgs boson decays, though further analysis is needed to confirm the observations.
The DUNE project will beam tiny neutrinos across vast distances. But the first step involved moving a heavier material: 1 million tons of rock.
Explore how QBism reframes science by placing the observer at the heart of quantum reality.
Here in the 21st century, quantum computing is quickly going from a dream to a reality. But what's hype, and what's actually true?
In our Universe, matter is made of particles, while antimatter is made of antiparticles. But sometimes, the physical lines get real blurry.
U.S. particle physicists recently recommended a list of major research projects that they hope will receive federal funding.
For generations, physicists have been searching for a quantum theory of gravity. But what if gravity isn't actually quantum at all?
In the earliest stages of the hot Big Bang, equal amounts of matter and antimatter should have existed. Why aren't they equal today?
Scientists will be able to make detailed "Claymation-like" movies of chemical reactions.
What do ghosts and anomalous galaxy rotation rates have in common? Some sci-fi enthusiasts believe the answer involves "parallel universes."
If you said "with the Big Bang," congratulations: that was our best answer as of ~1979. Here's what we've learned in all the time since.
There's a quantum limit to how precisely anything can be measured. By squeezing light, LIGO has now surpassed all previous limitations.
Isaac Newton and Albert Einstein are locked in an eternal battle over the nature of gravity. Whose side are you on?
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.
Our greatest tool for exploring the world inside atoms and molecules, and specifically electron transitions, just won 2023's Nobel Prize.
The matter that creates black holes won't be what comes out when they evaporate. Will the black hole information paradox ever be solved?
A relatively new interpretation of quantum mechanics asks us to reimagine the process of science itself.
American students are being compelled to specialize earlier and earlier. Here's what it takes to build a successful physics foundation.
Can quantum computers do things that standard, classical computers can't? No. But if they can calculate faster, that's quantum supremacy.
By probing the Universe on atomic scales and smaller, we can reveal the entirety of the Standard Model, and with it, the quantum Universe.

Theoretical physics professor Michio Kaku outlines the evolution of computers from analog to digital and introduces quantum computers as the next frontier.
Nature may not allow us full access to the weirdness of quantum mechanics.
All biological systems are wildly disordered. Yet somehow, that disorder enables plant photosynthesis to be nearly 100% efficient.
Headlines have blared that quasar ticking confirms that time passed more slowly in the early Universe. That's not how any of this works.
Quantum physics is starting to show up in unexpected places. Indeed, it is at work in animals, plants, and our own bodies.
