There is no such thing as a void in the Universe.

The properties of a ghostly particle called a neutrino are coming into focus.

The “first cause” problem may forever remain unsolved, as it doesn’t fit with the way we do science.

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

As we pursue the leadership difference we seek, we attract fuel and generate heat. The trick is to avoid burnout.

From how life emerged on Earth to why we dream, these unanswered questions continue to perplex scientists.

A great many cosmic puzzles still remain unsolved. By embracing a broad and varied approach, particle physics heads toward a bright future.

You can only create or destroy matter by creating or destroying equal amounts of antimatter. So how did we become a matter-rich Universe?

Perhaps the whole Universe is the result of a vacuum fluctuation, originating from what we could call quantum nothingness. 

Amplifying the energy within a laser, over and over, won’t get you an infinite amount of energy. There’s a fundamental limit due to physics.

If light can’t be bent by electric or magnetic fields (and it can’t), then how do the Zeeman and Stark effects split atomic energy levels?

The brightest gamma-ray burst ever observed, GRB 221009A behaved in unexpected ways that might help us understand how they occur.

Is the Universe finite or infinite? Does it go on forever or loop back on itself? Here’s what would happen if you traveled forever.

Don’t put all your eggs in one basket.

In the quest to measure how antimatter falls, the possibility that it fell “up” provided hope for warp drive. Here’s how it all fell apart.

Black holes encode information on their surfaces, but evaporate away into Hawking radiation. Is that information preserved, and if so, how?

There’s no upper limit to how massive galaxies or black holes can be, but the most massive known star is only ~260 solar masses. Here’s why.

Nothing can escape from a black hole. So where do Hawking radiation, relativistic jets, and X-ray emissions around black holes come from?

The Big Bang’s hot glow faded away after only a few million years, leaving the Universe dark until the first stars formed. Oh, the changes!

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

Symmetries aren’t just about folding or rotating a piece of paper, but have a profound array of applications when it comes to physics.

If you gave me $400 and I gave you $3.15, would you consider yourself wealthier? That’s a financial analogy for the supposed fusion power “breakthrough.”

The world needs a moral defense of progress based in humanism and agency.

From nothing to everything: How zero changed our understanding of the universe, forever.

Two fundamentally different ways of measuring the expanding Universe disagree. What’s the root cause of this Hubble tension?

Are quantum fields real, or are they simply calculational tools? These 3 experiments show that if energy is real, so are quantum fields.

Big Think interviews Angie Westbrock, CEO of Standard AI, to learn the secrets of adapting to the winds of change.

We are about to learn a lot more about the most elusive of cosmic particles.

It was a particularly good year for biotech and medical technology. There were also notable advances in energy.

The passage of time is something we all experience, as it takes us from one moment to the next. But could it all just be an illusion?
