How do physicists solve a problem like entropy?
Quantum uncertainty and wave-particle duality are big features of quantum physics. But without Pauli's rule, our Universe wouldn't exist.
If you look into a mirror, you'll notice that left-and-right are reversed, but up-and-down is preserved. The reason isn't what you think.
You are an energy field — but not the “chakras” or “auras” kind.
With a massive, charged nucleus orbited by tiny electrons, atoms are such simple objects. Miraculously, they make up everything we know.
Time gets a little strange as you approach the speed of light.
We are about to learn a lot more about the most elusive of cosmic particles.
So far, two papers have been retracted, and a third is under investigation. Accusations of plagiarism appear convincing.
It's the best-known transcendental number of all-time, and March 14 (3/14 in many countries) is the perfect time to celebrate Pi (π) Day!
Somewhere out there in the Universe is the heaviest neutron star, and elsewhere lies the lightest black hole. Where's the line between them?
Even with quantum teleportation and the existence of entangled quantum states, faster-than-light communication still remains impossible.
Not even Einstein immediately knew the power of the equations he gave us.
What kind of object will you form? What will its fate be? How long will a star live? Almost everything is determined by mass alone.
Unless you confront your theory with what's actually out there in the Universe, you're playing in the sandbox, not engaging in science.
Since its observation discovery in the 1990s, dark energy has been one of science's biggest mysteries. Could black holes be the cause?
From the Big Bang to dark energy, knowledge of the cosmos has sped up in the past century — but big questions linger.
The answer to the age-old philosophical question of whether there is meaning in the Universe may ultimately rest upon the power of information.

The solution involves the infamous Navier-Stokes equations, which are so difficult, there is a $1-million prize for solving them.
The Universe isn't as "clumpy" as we think it should be.
When you bring two fingers together, you can feel them "touch" each other. But are your atoms really touching, and if so, how?
To Einstein, nature had to be rational. But quantum physics showed us that there was not always a way to make it so.
Humanity's newest, most powerful space telescope is performing even better than predicted. The reason why is unprecedented.
The central equation of quantum mechanics, the Schrödinger equation, is different from the equations found in classical physics.
It isn't just identical particles that can be entangled, but even those with fundamentally different properties interfere with each other.
Laser-guided lightning systems could someday offer much greater protection than lightning rods.
Though a single measurement is not enough to definitively decide the debate, this is a major win for dark matter proponents.
Yes, dark energy is real. Yes, distant galaxies recede faster and faster as time goes on. But the expansion rate isn't accelerating at all.
The quantum world — and its inherent uncertainty — defies our ability to describe it in words.
For years and over three separate experiments, "lepton universality" appeared to violate the Standard Model. LHCb at last proved otherwise.
It's spooky, and it's happening all around us. And inside us.
