The Sun will eventually become a red giant star, swallowing Mercury and Venus in the process. But what will happen to Earth? There are a few existential questions we can ask […]
While the world considers future trips to Mars, two astrophysicists make a case for exploring asteroids.
Searching for truth in unorthodox ways can be a valuable exercise. But Anatoly Fomenko's alternate world history is just plain weird.
The psychology of alien contact largely revolves around the concept of "otherness." We need to learn to be comfortable around strange things.
First drawn in 1935, Hu Line illustrates persistent demographic split – how Beijing deals with it will determine the country's future.
Physics demands that it couldn’t be any other way. Here’s why. Ask anyone — even someone with no background in science — to name something that Einstein did, and odds are they’ll come back with […]
CERN’s bold new proposal has physicists confronting the biggest question of all: is building a new collider worth it? If you want to discover anything novel about the natural, physical […]
It doesn’t have to be a science-fiction dream. For as long as human beings have been watching the night sky, we’ve dreamed of visiting other worlds and truly seeing what’s […]
For years, astronomers have been puzzled by an excess of antimatter particles. Unfortunately, dark matter is probably not the solution. When you look out at the Universe, what you see […]
The hard part was keeping the list down to ten.
Cognitive psychologist Donald Hoffman hypothesizes we evolved to experience a collective delusion — not objective reality.
The Sudbury neutrino observatory, which was instrumental in demonstrating neutrino oscillations and the massiveness of neutrinos. With additional results from atmospheric, solar, and terrestrial observatories and experiments, we may not […]
Forget the speed of light or the electron’s charge. This is the physical constant that really matters. Why is our Universe the way it is, and not some other way? There […]
As soon as you start thinking about energy and gravity, you’ll realize the need to go beyond it. When it comes to a science like physics, theoretical expectations must always be […]
It’s perhaps the most famous equation of all, with lessons about reality for every one of us. If you’ve ever heard of Albert Einstein, chances are you know at least one […]
A new study shows how interbreeding of modern humans and Neanderthals boosted our genomes.
The Universe has been making stars for nearly the entire 13.8 billion years of its history. Here’s what we know. It’s been 13.8 billion years since the hot Big Bang, and […]
The Universe is filled with something, as opposed to nothing, and scientists don’t understand it. When we look around at the Universe: at the planets and stars, at the galaxies […]
And, even with all we know, what still remains unexplained? At a fundamental level, our Universe is made of particles, forces, interactions, and the fabric of space and time. Spacetime […]
Immediately after the Big Bang, the Universe was more energetic than ever. What was it like? When we look out at the Universe today, we see that it’s full of stars […]
If you think you have problems today, be glad you’re not moving at the speed of light. Special relativity, even though it’s over 100 years old, is still one of the […]
