Why Einstein must be wrong: In search of the theory of gravity

Einstein’s theory of general relativity suggests that our universe originated in a Big Bang. But black holes, and their gravitational forces, challenge the limits of Einstein’s work.

3 reasons we use graphic novels to teach math and physics

Graphic novels pair text and images to explain complex topics – from thermodynamics to abstract math – without alienating STEM-averse students.

Researchers dig deep underground in hopes of finally observing dark matter

To detect dark matter, you need to build an ultra-sensitive detector and put it somewhere ultra-quiet. For one physics collaboration, that place is almost a mile under Lead, S.D.

Measuring helium in distant galaxies may give physicists insight into why the universe exists

The way particles interacted while the universe was forming seconds after the Big Bang could explain why the universe exists the way it does – a physicist explains matter-antimatter asymmetry.
The idea that the Coriolis force influences how water drains frequently appears in popular culture and urban legends. frantic00 / Shutterstock

Does the direction water rotates down the drain depend on which hemisphere you’re in? Debunking the Coriolis effect in your sink

This physical effect does explain how some massive natural phenomena like hurricanes behave. But on the scale of water in your sink – not so much.
Researchers can use mirrorlike beam splitters to put phonons, or quantum sound particles, into a state of superposition. Peter Allen via University of Chicago

How splitting sound might lead to a new kind of quantum computer

Scientists show they can create quantum superpositions of sound particles, pointing to the potential for mechanical quantum computers.

Do you crush microbes when you step on them?

You can squash small bugs by stepping on them, but can you crush even tinier microorganisms like viruses and bacteria? It turns out that you’d need to apply a lot of pressure.

Why is the sky dark at night? The 200-year history of a question that transformed our understanding of the Universe

The darkness of the night sky seems so obvious as to need no explanation – yet it has intrigued and baffled scientists for centuries.
