No matter how good our measurement devices get, certain quantum properties always possess an inherent uncertainty. Can we figure out why?

It’s not about particle-antiparticle pairs falling into or escaping from a black hole. A deeper explanation alters our view of reality.

The evidence that the Universe is expanding is overwhelming. But how? By stretching the existing space, or by creating new space itself?

Glueballs are an unusual, unconfirmed Standard Model prediction, suggesting bound states of gluons alone exist. We just found our first one.

Dark energy is one of the biggest mysteries in all the Universe. Is there some way to avoid “having to live with it?”

Contrary to common experience, not everything needs a medium to travel through. Overcoming that assumption removes the need for an aether.

Einstein called his idea “abominable,” but the world of physics came around to embracing the views of Georges Lemaître.

Philosophy can focus on some dull topics. Luckily, some thinkers have spent lots of time on the philosophy of sex

No matter how good our measurement devices get, certain quantum properties always possess an inherent uncertainty. Can we figure out why?

Holograms preserve all of an object’s 3D information, but on a 2D surface. Could the holographic Universe idea lead us to higher dimensions?

Scientists can make substantial progress without fully understanding exactly what they’re doing.

The difference between predictions and observations of the magnetic properties of muons suggests a mystery for the Standard Model.

We know the Universe is expanding, but scientists don’t agree on the rate. This is a legitimate problem.

Without wormholes, warp drive, or some type of new matter, energy, or physics, everyone is limited by the speed of light. Or are they?

Taught in every introductory physics class for centuries, the parabola is only an imperfect approximation for the true path of a projectile.

Empty space itself, the quantum vacuum, could be in either a true, stable state or a false, unstable state. Our fate depends on the answer.

If our Universe were born a little differently, there wouldn’t have been any planets, stars, galaxies, or chemically interesting reactions.

Nothing lives forever, at least, not in the physical Universe. But relativity allows us to get closer than ever, from one perspective.

The mutual distance between well-separated galaxies increases with time as the Universe expands. What else expands, and what doesn’t?

We think of physical reality as what objectively exists, independent of any observer. But relativity and quantum physics say otherwise.

A concept known as “wave-particle duality” famously applies to light. But it also applies to all matter — including you.

If you bring too much mass or energy together in one location, you’ll inevitably create a black hole. So why didn’t the Big Bang become one?

Unless you confront your theory with what’s actually out there in the Universe, you’re playing in the sandbox, not engaging in science.

The first observational evidence showing the Universe is expanding is 100 years old now: in 2023. Here’s the story of its 100th anniversary.

Twin Health lets patients with diabetes see what’s happening inside their own body and can model each patient’s unique metabolism.

The Universe didn’t begin with a bang, but with an inflationary “whoosh” that came before. Here are the biggest questions that still remain.

Headlines have blared that quasar ticking confirms that time passed more slowly in the early Universe. That’s not how any of this works.

“It is healthy and normal to be afraid of death.”

Since its observation discovery in the 1990s, dark energy has been one of science’s biggest mysteries. Could black holes be the cause?

Here on Earth, we commonly use terms like weight (in pounds) and mass (in kilograms) as though they’re interchangeable. They’re not.
