Science and philosophy seem to be separate fields, but philosophical advancements have made the world more accepting of debate and unorthodox ideas.

The Standard Model of elementary particles has three nearly identical copies of particles: generations. And nobody knows why.

Who — or what — really controls your mind?

At a fundamental level, only a few particles and forces govern all of reality. How do their combinations create human consciousness?

Chemical energy, where electrons transition in atoms, powers the reactions we see. But two other types hold more promise than all the rest.

If there are three neutrino species, all with different masses, then how is energy conserved when they oscillate from one flavor to another?

New studies stretch the boundaries of physics, achieving quantum entanglement in larger systems.

Lord Kelvin is thought to have said there was nothing new to discover in physics. His real view was the opposite.

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.

A wild, compelling idea without a direct, practical test, the Multiverse is highly controversial. But its supporting pillars sure are stable.

The ANITA experiment found cosmic rays shooting out of Antarctica. One interpretation claims “parallel Universes,” but is that right?

We bake pies for Pi Day, so why not celebrate other mathematical achievements.

AI can deliver a more equitable and prosperous future — if accompanied by ethical and responsible stewardship.

The closest known star that will soon undergo a core-collapse supernova is Betelgeuse, just 640 light-years away. Here’s what we’ll observe.

Giambattista della Porta’s contributions to codebreaking changed the course of communication.

The idea of gravitational redshift crossed Einstein’s mind years before General Relativity was complete. Here’s why it had to be there.

Ever since the start of the hot Big Bang, time ticks forward as the Universe expands. But could time ever run backward, instead?

There might be a hard limit to our knowledge of the Universe.

If there really is another version of you out there in a parallel universe, what can that teach us about reality?

“Even with my training, I still got insights from the book’s descriptions. That’s how good Carroll is at explaining physics.”

Is science absolute? Its truths and discoveries guide us toward the nature of reality, but we must always remain open-minded to revisions.

In the very early Universe, practically all particles were massless. Then the Higgs symmetry broke, and suddenly everything was different.

“When molecules misbehave, it can lead to great insight.”

The cat-and-mouse game between China and the world’s semiconductor companies is already having enormous consequences.

Do they have real, observable effects, or are they merely calculational tools?

Could anyone still meet the Theoretical Minimum?

A rift in thinking about who should control powerful new technologies sent the brothers on diverging paths. For one, the story ended with a mission to bring science to the public.

More than any other of Einstein’s equations, E = mc² is the most recognizable to people. But what does it all mean?

Cosmologists are largely still in the dark about the forces that drive the Universe.

Is the physical universe independent from us, or is it created by our minds, as suggested by scientist Robert Lanza?
