Quantum Physics
Quantum mechanics has taught us that even empty space contains energy. "Negative energy" is the state of having less energy than empty space.
For nearly a century, physicists have argued over how to interpret quantum physics. But reality exists independent of any interpretation.
Every proton contains three quarks: two up and one down. But charm quarks, heavier than the proton itself, have been found inside. How?
Light carries with it the secrets of reality in ways we cannot completely understand.
The science fiction dream of a traversable wormhole is no closer to reality, despite a quantum computer's suggestive simulation.
Like Dua Lipa, he had to create new rules.
The answer to this question is key to understanding why anything exists.
The quantum world is one in which rules that are completely foreign to our everyday experience dictate bizarre behavior.
Quantum entanglement may remain spooky, but it has a very practical side.
We are not yet at the point where quantum communications can be deployed to secure the internet, but we might not be far off.
Einstein always loses in the quantum realm.
Uncertainty is inherent to our Universe.
They say that nobody understands quantum mechanics. But thanks to these three pioneers in quantum entanglement, perhaps we do.
From the tiniest subatomic scales to the grandest cosmic ones, solving any of these puzzles could unlock our understanding of the Universe.
No matter how good our measurement devices get, certain quantum properties always possess an inherent uncertainty. Can we figure out why?
In our common experience, you can't get something for nothing. In the quantum realm, something really can emerge from nothing.
If your computer crashes, it might be due to a star that exploded somewhere in the Universe millions of years ago.
In special relativity, the statement that two events happened at the same time is meaningless.
The anthropic principle has fascinating scientific uses, where the simple fact of our existence holds deep physical lessons. Don't abuse it!
The false assumption the Multiverse relies on is that something which exists requires an explanation.
Lasers are all around you. This ubiquitous technology came from our understanding of quantum physics.
The way to understand the earliest moments of creation is to recreate those conditions and study them. Why would we stop now?
From the explosions themselves to their unique and vibrant colors, the fireworks displays we adore require quantum physics.
On July 4, we celebrate the tenth anniversary of the discovery of the Higgs boson, the missing piece of the Standard Model of particle physics.
There is nothing more important to science than its ability to prove ideas wrong.
Humans who've lived through the same events often remember them differently. Could quantum physics be responsible?
According to renowned physicist Christophe Galfard, physics can’t explain our universe - yet.

Everything is made of matter, not antimatter, including black holes. If antimatter black holes existed, what would they do?
Time isn't the same for everyone, even on Earth. Flying around the world gave Einstein the ultimate test. No one is immune from relativity.
