Not building one means giving up on brute force. We’re not yet ready to do that. There’s a problem with the field of high-energy physics, and it’s the biggest one imaginable. […]
In principle, the laws of physics are the same forwards and backwards. But in practice, time only runs in one direction. Most of the laws of physics are the same […]
It might be the biggest conundrum facing cosmology today. But perhaps it’s not a controversy; it might be a clue. https://soundcloud.com/ethan-siegel-172073460/starts-with-a-bang-44-the-expanding-universe/ One of the biggest conundrums in the Universe surrounds the […]
Why would people rate certain names as being more extraverted or more agreeable?
Over the past 30 years, we’ve revolutionized what we know about the Universe. But we couldn’t have done it without these lessons. On April 24, 1990, the Hubble Space Telescope rocketed […]
Doomsday prophesies have never once come to pass, but they’ve never had science on their side like this before. Every year, the Earth completes an orbital revolution around the Sun, returning […]
The planet has had life on it, in some form or another, for nearly as long as Earth has existed. If you came to our Solar System right after it formed, […]
When you struggle with anxiety or depression, sex may be the last thing on your mind. But understanding the physiological and mental benefits of a healthy sex life can help it become a tool for well-being.
The darkness of the night sky was a mystery for generations of humans. Here’s the reason why. From our perspective here in the Solar System, it makes absolute intuitive sense why […]
Colonizing the Red Planet isn’t a bad idea in theory. But . . .
A longstanding astronomical gap between neutron stars and black holes is finally coming to a close. Astronomy has taken us so far into the Universe, from beyond Earth to the planets, […]
The Category 5 hurricane was moving at speeds of about 1 mph over the Bahamas on Sunday and Monday.
Is capitalism naturally unempathetic?
The expanding Universe really is accelerating, and no dusty scenario can explain it. 20 years ago, our understanding of the Universe underwent a revolution. For generations, we had known the Universe […]
What do the inventions of the future look like?
The visible light portion of the spectrum is tiny compared to the whole thing. Here’s what we’re missing. When you look at the Milky Way in visible light, you might see […]
What foods are women reaching for? Carbs and fats and sweets.
If parallel Universes or the multiverse are real, we might someday encounter a visitor who hails from another one. Here’s what to do. There are a lot of things that are […]
A vacuum cleaner is the wrong picture. Time to bust that myth. There are no classes of object in our Universe more extreme than black holes. With so much mass present […]
Some nations can’t afford to make climate change a political issue.
Number of proton-neutron pairs determine how fast the particles move, results suggest.
What took hundreds of millions of years to create is being wasted on… party balloons? There’s a natural resource found beneath Earth’s surface that’s been building up for hundreds of […]
It was so well-motivated and compelling. But the particles never appeared. Every so often, an idea comes along in theoretical physics that’s undeniably profound. When a single idea can solve […]
The dream of an ‘Earth-like’ planet showcases our astrobiological ignorance. Over the past decade, our understanding of what planets exist around stars other than our own has exploded. The number […]
Forget Copenhagen, Many-Worlds, Pilot Waves and all the others. What you’re left with is reality. When it comes to understanding the Universe, scientists have traditionally taken two approaches in tandem with […]
If you think it expanded faster than light-speed, you need to read this. If the Universe is 13.8 billion years old, and the speed of light is truly our cosmic speed […]
Our favorite over-the-counter medication has its limits.
Pay attention to the decisions made by the provinces.
The Earth is getting warmer, and humans are the cause. This is why. Let’s play pretend for a moment. Pretend, if you can, that you’ve never heard about the idea of […]
