In logic, 'reductio ad absurdum' shows how flawed arguments fall apart. Our absurd Universe, however, often defies our intuitive reasoning.
The science fiction dream of a traversable wormhole is no closer to reality, despite a quantum computer's suggestive simulation.
Much like energy and nutrients flow in a continuous cycle between the elements of a natural ecosystem, a free flow of knowledge fuels the growth of a learning ecosystem.
In General Relativity, white holes are just as mathematically plausible as black holes. Black holes are real; what about white holes?
A part of human nature needs to be challenged and feel strong. Today, we fulfill that need with "surrogate activities."
In our Universe, matter is made of particles, while antimatter is made of antiparticles. But sometimes, the physical lines get real blurry.
Extreme home environments — either very supportive or harshly negligent — tend to produce more sensitive kids.
For a substantial fraction of a second after the Big Bang, there was only a quark-gluon plasma. Here's how protons and neutrons arose.
U.S. particle physicists recently recommended a list of major research projects that they hope will receive federal funding.
Contrary to common experience, not everything needs a medium to travel through. Overcoming that assumption removes the need for an aether.
James Suzman lived with a tribe of hunter-gatherers to witness how an ancient culture survives one of the most brutal climates on Earth. His learnings may surprise you.

There's an extra source of massive "stuff" in our Universe beyond what gravitation and normal matter can explain. Could light be the answer?
In our common experience, you can't get something for nothing. In the quantum realm, something really can emerge from nothing.
A cute mathematical trick can "rescale" the Universe so that it isn't actually expanding. But can that "trick" survive all our cosmic tests?
Two of the answers add a dimension to physics that doesn’t belong there. Maybe we could call it "astrotheology."
There’s really only one mistake you can make: continue doing the same thing you already know is hurting you and expect a different result.
Everything we observe beyond our Local Group is speeding away from us, omnidirectionally. If the Universe is expanding, where is the center?
Supermassive black holes at the centers of galaxies gobble up whatever matter ventures too close, becoming active. Here's how they work.
Gamma-ray bursts are so powerful they could vaporize the Earth from 200 light-years away. Recreating them in the lab is not easy.
The great hope is that beyond the indirect, astrophysical evidence we have today, we'll someday detect it directly. But what if we can't?
The Universe is expanding, and the Hubble constant tells us how fast. But how can it be a constant if the expansion is accelerating?
The world is aging, and with age comes vision decline. New research may have found how to improve eyesight in an accessible way.
Everything acts like a wave while it propagates, but behaves like a particle whenever it interacts. The origins of this duality go way back.
We confidently state that the Universe is known to be 13.8 billion years old, with an uncertainty of just 1%. Here's how we know.
In the wake of the pandemic, the crystal industry boomed, with customers hoping the stones might relieve a little anxiety.
The first stars in the Universe were made of pristine material: hydrogen and helium alone. Once they die, nothing escapes their pollution.
The new electrically conductive substrate could be the future of hydroponic farming.
Before there were planets, stars, and galaxies, before even neutral atoms or stable protons, there was the Big Bang. How did we prove it?
The Kardashev scale ranks civilizations from Type 1 to Type 3 based on energy harvesting.
