The Multiverse fuels some of the 21st century’s best fiction stories. But its supporting pillars are on extremely stable scientific footing.

Carrie Berk reveals how she transformed her struggle with anxiety and internet fame by changing her perception and finding her true voice as a writer.

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

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

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

From forming bound states to normal scattering, many possibilities abound for matter-antimatter interactions. So why do they annihilate?

For every proton, there were over a billion others that annihilated away with an antimatter counterpart. So where did all that energy go?

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

Today, the deepest depths of intergalactic space aren’t at absolute zero, but at a chill 2.73 K. How does that temperature change over time?

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.”

Nature may not allow us full access to the weirdness of quantum mechanics.

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.

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

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

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

Our greatest tool for exploring the world inside atoms and molecules, and specifically electron transitions, just won 2023’s Nobel Prize.

Researchers devise a record-breaking laser transmission that avoids atmospheric interference.

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

The concept of ‘relativistic mass’ has been around almost as long as relativity has. But is it a reasonable way to make sense of things?

Traveling back in time is a staple of science fiction movies. But according to Einstein, it’s a physical possibility that’s truly allowed.

There are a wide variety of theoretical studies that call our Standard Model of cosmology into question. Here’s what they really mean.

The multiverse is an idea that has gained a lot of traction in popular culture. But what does science have to say about it?

Most waves need a medium to travel through. But the way that light and gravitational waves travel shows that space can’t be a medium at all.

Successful alpha leadership is more about caring and healing than dog-eat-dog supremacy.

Science cannot help us understand or describe first-person experience. Zen koans are a powerful form for helping us reach that description.

Almost everyone asserts that the Big Bang was the beginning of everything, followed by inflation. Has everyone gotten the order wrong?

Whenever someone waxes poetic about terraforming alien worlds, it’s worth taking a moment to consider the ethical implications of the proposal.

The observation that everything we know is made out of matter and not antimatter is one of nature’s greatest puzzles. Will we ever solve it?

For centuries, Newton’s inverse square law of gravity worked beautifully, but no one knew why. Here’s how Einstein finally explained it.
