The biggest nuclear blast in history came courtesy of Tsar Bomba. We could make something at least 100 times more powerful.

The Universe is expanding, and the Hubble constant tells us how fast. But how can it be a constant if the expansion is accelerating?
Dark energy is one of the biggest mysteries in all the Universe. Is there some way to avoid "having to live with it?"
If the Universe is expanding, and the expansion is accelerating, what does that tell us about the cause of the expanding Universe?
In the early stages of the hot Big Bang, matter and antimatter were (almost) balanced. After a brief while, matter won out. Here's how.
Old coal mines can be converted into "gravity batteries" by retrofitting them with equipment that raises and lowers giant piles of sand.
From ancient Greek cosmology to today's mysteries of dark matter and dark energy, explore the relentless quest to understand the Universe's invisible forces.
It was a particularly good year for biotech and medical technology. There were also notable advances in energy.
Cosmic inflation is the state that preceded and set up the hot Big Bang. Here's what the Universe was like during that time period.
His grandfather, a member of Oppenheimer’s atomic bomb team, foresaw the potential of nuclear energy to power cities — not destroy them.
In our Universe, all stable atomic nuclei have protons in them; there's no stable "neutronium" at all. But what's the reason why?
Innovative thinking has done away with problems that long dogged the electric devices — and both scientists and environmentalists are excited about the possibilities.
In a far-reaching discovery with astrophysicist Karolina Garcia, we discuss what's in the Universe and how it grew up.
There is no such thing as a void in the Universe.
The first elements in the Universe formed just minutes after the Big Bang, but it took hundreds of thousands of years before atoms formed.
According to neuropsychologist Julia DiGangi, no one can live a life free of emotional pain. We can only choose how those emotions empower us.
The miniaturization of particle accelerators could disrupt medical science.
Are quantum fields real, or are they simply calculational tools? These 3 experiments show that if energy is real, so are quantum fields.
We are about to learn a lot more about the most elusive of cosmic particles.
Perhaps the whole Universe is the result of a vacuum fluctuation, originating from what we could call quantum nothingness.
In many ways, it was worse than Chernobyl.
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?
Lithium-ion batteries pose challenges for our transition toward renewable energy. Sodium-sulfur batteries might be a solution.
The brightest gamma-ray burst ever observed, GRB 221009A behaved in unexpected ways that might help us understand how they occur.
Smarter building materials can control indoor temperatures without external power.
In the very early Universe, practically all particles were massless. Then the Higgs symmetry broke, and suddenly everything was different.
Some 13.8 billion years ago, the Universe became hot, dense, and filled with high-energy quanta all at once. Here's what it was like.
There are a wide variety of theoretical studies that call our Standard Model of cosmology into question. Here's what they really mean.
If nature were perfectly deterministic, atoms would almost instantly all collapse. Here's how Heisenberg uncertainty saves the atom.
Because of dark energy, distant objects speed away from us faster and faster as time goes on. How long before every galaxy is out of reach?
