Scientists work on it, it’s consistent with science, and it hopes to be the biggest scientific breakthrough of all. But it’s missing one key ingredient. “As of now, string theorists […]
The two best-explored outer Solar System worlds orbit one another. But no one was prepared for what New Horizons saw. “Just as a Chihuahua is still a dog, these ice dwarfs […]
If they shoot out straight lines of high-energy particles, why do they carve bubble-like shapes? “When a person starts to talk about their dreams, it’s as if something bubbles up […]
And why it might spell trouble for dark energy as we know it. “That’s all regular matter, just five percent. A quarter is “dark matter,” which is invisible and detectable only […]
Nearly a quarter of Americans rely on sleeping pills—a trend that’s feeding obesity and depression levels.
That our atoms come from stars? You’ve got to think bigger than that! “The older people that one admires seem to be fearless. They go right out into the world. It’s […]
13.8 billion years is a great number. But how sure are we of this, and how did we get there? “Nobody grows old merely by living a number of years. We […]
If there is a quantum theory of gravity, is String Theory the only game in town? “I just think too many nice things have happened in string theory for it to […]
It’s rare to find a galaxy where the arms wrap around even a full 360 degrees. But after billions of years, why is that? “The farther we peer into space, the […]
The pop-a-pill solution is a non-solution. But what is the alternative?
New research shows that the most effective leaders, from Abraham Lincoln to Jeff Bezos, are always questioning their own convictions.
They won this year’s Nobel Prize in Physics, but their legacy’s just beginning. “I know all about neutrinos, and my friend here knows about everything else in astrophysics.” –John Bahcall, […]
Earth day may have been last week, but the lessons we learned about Earth from space are with us always. “We are not learning to view ourselves as an advanced, evolving […]
An incredible live-blog of an incredible event. “It’s becoming clear that in a sense the cosmos provides the only laboratory where sufficiently extreme conditions are ever achieved to test new […]
Four years ago, the world was shaken with the announcement of a planet around Alpha Centauri. But was it real? “You’re on Earth. There’s no cure for that.” –Samuel Beckett If […]
The force that has only been seen on the largest cosmic scales affects smaller ones, too. We just need to look well enough. “There are still so many questions to answer. […]
What’s the science behind the need to add an extra day to the calendar every so often? “Will you or won’t you? Should you or shouldn’t you? Use this day […]
The way you experience time changes when you near the speed of light. So what happens when you actually reach it? “Everyone has his dream; I would like to live […]
How many does it take to give us our Universe, and what’s left unexplained? “The joy of life consists in the exercise of one’s energies, continual growth, constant change, the […]
Happy Birthday To The Person Who Literally Brought Us The Entire Universe “Equipped with his five senses, man explores the universe around him and calls the adventure Science.” –Edwin Hubble As […]
Living longer, but worrying more. Why?
It’s said to be the majority of matter in the Universe, but how sure are we of that? “For the moment we might very well call them DUNNOS (for Dark Unknown […]
Astrophysicists contemplate whether “mirror” dark matter causes cancer.
There were two periods of exponential expansion in the Universe: one today and one long ago. Are they related? “What is wild cannot be bought or sold, borrowed or copied. […]
Which makes you wonder what other “candidate worlds” aren’t worlds after all. “These types of systems could be ubiquitous in the universe. This is a really exciting time for planet hunters.” […]
Is everything astonishingly simple, though? Or is this a grandiose claim that falls flat when confronted with the evidence? “My main interest is the problem of the singularity. If we […]
Religion is part of the problem. But the bigger picture is much larger than any one book.
Apparently, there’s a lot more to be worried about than the environment.
Is it how the Universe began, or just how our observable Universe began? They’re not the same! “These theories were based on the hypothesis that all the matter in the universe […]
