The concept of the warp drive is currently at odds with everything we know to be true about physics.
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.
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?
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So far, two papers have been retracted, and a third is under investigation.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.

Is science close to explaining everything about our Universe? Physicist Sabine Hossenfelder reacts.
Unless you confront your theory with what's actually out there in the Universe, you're playing in the sandbox, not engaging in science.

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 […]
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.

Left–Right, Back–Forth, Up–Down. What’s the fourth dimension?
Laser-guided lightning systems could someday offer much greater protection than lightning rods.

Do humans have souls, or are we just particles? Physicist Sabine Hossenfelder explains.
It's spooky, and it's happening all around us. And inside us.

Everything you ever wanted to know about the Universe, explained by physicist Sean Carroll.
A concept known as "wave-particle duality" famously applies to light. But it also applies to all matter — including you.
Its implications go well beyond the Earth itself, affecting even the future of space travel.
Like Dua Lipa, he had to create new rules.
Vanadium dioxide is a strange material that "remembers" information and when it was stored. This is akin to biological memory.
