Yes, “the laws of physics break down” at singularities. But something really weird must have happened for black holes to not possess them.
The problem of the electroweak horizon haunts the standard model of cosmology and beckons us to ask how deep a rethink the model may need.
Once the initial blaze of heat dissipated, the constituent particles of atoms were free to bind.
Quantum uncertainty and wave-particle duality are big features of quantum physics. But without Pauli’s rule, our Universe wouldn’t exist.
From quarks and gluons to giant galaxy clusters, everything that exists in our Universe is determined by what is (and isn’t) bound together.
The LHC has a long, productive life ahead of it. An upgraded version, called the “High Luminosity LHC,” will be available in 2028.
Cosmologists are largely still in the dark about the forces that drive the Universe.
If you look into a mirror, you’ll notice that left-and-right are reversed, but up-and-down is preserved. The reason isn’t what you think.
What would become the Big Bang model started from a crucial idea: that the young Universe was denser and hotter.
For decades, theorists have been cooking up “theories of everything” to explain our Universe. Are all of them completely off-track?
You are an energy field — but not the “chakras” or “auras” kind.
The double-slit experiment, hundreds of years after it was first performed, still holds the key mystery at the heart of quantum physics.
With a massive, charged nucleus orbited by tiny electrons, atoms are such simple objects. Miraculously, they make up everything we know.
Time gets a little strange as you approach the speed of light.
That scary swirling void from which nothing can escape is our perfect universal translation tool.
We are about to learn a lot more about the most elusive of cosmic particles.
With a bigger, better, and more sensitive detector, the XENON collaboration joins LZ and PANDA-X in constraining WIMP dark matter.
2023 is an exciting time for the study of quark-gluon plasmas.
If there are three neutrino species, all with different masses, then how is energy conserved when they oscillate from one flavor to another?
Everything everywhere all at once.
A non-invasive method for looking inside structures is solving mysteries about the ancient pyramid.
If you’re a massless particle, you must always move at light speed. If you have mass, you must go slower. So why aren’t any neutrinos slow?
Protons and neutrons are held together by the strong force: with 3 colors and 3 anticolors. So why are there only 8 gluons, and not 9?
ChatGPT doesn’t understand physics, but it memorizes very well and puts in extra effort.
When you combine the Uncertainty Principle with Einstein’s famous equation, you get a mind-blowing result: Particles can come from nothing.
Are quantum fields real, or are they simply calculational tools? These 3 experiments show that if energy is real, so are quantum fields.
Recent measurements of subatomic particles don’t match predictions stemming from the Standard Model.
The combination of charge conjugation, parity, and time-reversal symmetry is known as CPT. And it must never be broken. Ever.
Though quantum mechanics is an incredibly successful theory, nobody knows what it means. Scientists now must confront its philosophical implications.
A Fermilab study confirms decades-old measurements regarding the size and structure of protons.
