A physicist, a psychologist, and a philosopher walk into a bar and discuss a framework for thinking better in the 21st century.
Yes, the Universe is expanding, but if you’ve ever wondered, “How fast is it expanding,” the answer isn’t in terms of a speed at all.
Why do so many cultures celebrate holidays at the same time of year?

We are about to learn a lot more about the most elusive of cosmic particles.
The Big Bang’s hot glow faded away after only a few million years, leaving the Universe dark until the first stars formed. Oh, the changes!
The cosmic microwave background offers clues.
We are traveling in a realm that once exclusively belonged to the gods. Space travel will force humanity to rethink everything.
Chemical changes inside Mars’ core caused it to lose its magnetic field. This, in turn, caused it to lose its oceans. But how?
Leading a scientific revolution is easy: you just have to succeed where the current theory fails while equaling its successes. Good luck!
Gravitational waves carry enormous amounts of energy, but spread out quickly once they leave the source. Could they ever create black holes?
Lithium-ion batteries pose challenges for our transition toward renewable energy. Sodium-sulfur batteries might be a solution.
Unless you confront your theory with what’s actually out there in the Universe, you’re playing in the sandbox, not engaging in science.
Please stop calling our Sun an “average star.” It is philosophically dubious and astronomically incorrect.
When Einstein gave General Relativity to the world, he included an extraneous cosmological constant. How did his ‘biggest blunder’ occur?
Its implications go well beyond the Earth itself, affecting even the future of space travel.
It’s rare that one single image packs so much beauty and science simultaneously. This Hubble view of a nearby star-forming region has both.
One study suggested that the “Methuselah Star” is older than the Universe itself.
Like Mars today, Venus used to be a sci-fi superstar. Recent discoveries could re-ignite our interest in Earth’s “evil twin.”
Could life be widespread throughout the cosmos, in the subsurface oceans of ice-covered worlds? NASA’s Europa Clipper mission investigates.
A scientist’s first-hand account shows the world can tackle a global environmental crisis.
Archaeologists can learn how societies lived by studying what they left behind when they died. Astronomers are doing much the same thing.
Early relics and late-time objects give incompatible results for the expanding Universe. This independent anomaly intensifies the problem.
The largest particle accelerator and collider ever built is the Large Hadron Collider at CERN. Why not go much, much bigger?
If stars don’t go supernova at first, they can get a second chance after becoming a white dwarf. But can their companions survive?
For a thousand light-years in all directions, there’s a “bubble” that the Sun sits at the center of. Here’s the story behind it.
In the early stages of the hot Big Bang, there were only free protons and neutrons: no atomic nuclei. How did the first elements form from them?
A new, unexpected brightening, just 3 years after a massive dimming event, has astronomers watching Betelgeuse. Is a supernova imminent?
1859’s Carrington event gave us a preview of how catastrophic the Sun could be for humanity. But it could get even worse than we imagined.
One newly discovered, ancient star has a composition unlike any other. Explaining its existence is already blowing astronomers’ minds.
