Physics
Invisible cloaks. Ghost imaging. Scientists are manipulating light in ways that were once only science fiction.
The concept of the warp drive is currently at odds with everything we know to be true about physics.
Some processes, like quantum tunneling, have been shown to occur instantaneously. But the ultimate cosmic speed limit remains unavoidable.
The biggest nuclear blast in history came courtesy of Tsar Bomba. We could make something at least 100 times more powerful.
Michael Faraday's 1834 law of induction was the key experiment behind the eventual discovery of relativity. Einstein admitted it himself.
The multiverse pushes beyond the limits of the scientific method. From our vantage point in the Universe, we cannot know if it's real.
Up until 2002, we thought that the heaviest stable element was bismuth: #83 on the periodic table. That's absolutely no longer the case.
Just by observing the tiny amount of deuterium left over from the Big Bang, we can determine that dark matter and dark energy must exist.
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?
There are two methods to measure the expansion rate of the Universe. The results do not agree with each other, and this is a big problem.
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?
Quantum uncertainty and wave-particle duality are big features of quantum physics. But without Pauli's rule, our Universe wouldn't exist.
With a massive, charged nucleus orbited by tiny electrons, atoms are such simple objects. Miraculously, they make up everything we know.
So far, two papers have been retracted, and a third is under investigation.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.
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.

Frank Wilczek is celebrated for his investigations into the fundamental laws of nature that have transformed our understanding of the forces that govern our Universe. In this video, the MIT […]
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.

Why does time move forward but not backward? Physicist Sabine Hossenfelder explains.
