Searching for dark matter, the XENON collaboration found absolutely nothing out of the ordinary. Here's why that's an extraordinary feat.
Signals from across the universe point toward a fascinating possibility.
Disgusting behavior is often crucial to survival.
To understand ourselves and our place in the universe, "we should have humility but also self-respect," Frank Wilczek writes in a new book.
Watch the plasma slide down the prominence like a roller coaster! Our Sun, despite it’s outward appearance as a perfectly hot sphere, is anything but uniform. When take a closer look […]
On the largest scales, galaxies don't simply clump together, but form superclusters. Too bad they don't remain bound together.
Is the time crystal really an otherworldly revolution, leveraging quantum computing that will change physics forever?
A single lifetime is more than enough to take you to the limits of the Universe. Right now, there are only three things limiting how far our spacecrafts can take […]
Scientific surprises are often how science advances. But more often than not, they’re just bad science. When you’re a scientist, getting an unexpected result can be a double-edged sword. The best […]
The fabric of expanding space means that the farther away a galaxy is, the faster it appears to recede from us. However, that doesn’t mean that galaxies are actually moving […]
The anthropic principle has some fascinating scientific uses. And abuses, too. For thousands of years, humans have pondered the meaning of our existence. From philosophers who debated whether their minds could […]
When you’re trying to peel back the veil obscuring the fundamental nature of matter, you have to look absolutely everywhere. Sometimes, the solution to a puzzle you’ve been stymied by […]
Virtual reality continues to blur the line between the physical and the digital, and it will change our lives forever.
If galaxies are cities in the Universe, how unfortunate that our ‘cosmic country’ is dissolving. On the largest cosmic scales of all, planet Earth appears to be anything but special. […]
Moving close to the speed of light will cause time to pass appreciably differently for the traveler versus the person who remains in a constant frame of reference. But neither […]
If you think about the way a gravitational wave detector works, you might encounter a paradox. Here’s the solution. One of the greatest scientific achievements in all of human history […]
Two of our biggest science-fiction dreams might not remain fiction for much longer. Here’s how 21st-century science could make it real. For as long as human beings have looked up at […]
Human beings can exist on our world today because of the ingredients and rules that make up the Universe. If things were too different, intelligent observers of any type would […]
This list of 10 non-winners is 50% women, but 100% outrageous. In science, advances often come in great leaps. In hindsight, it’s easy to identify perhaps hundreds of small steps […]
Out of five vital questions, which one should we most desire the answer to? Despite all we’ve learned about physics, science, and the Universe before us, there are still some incredibly […]
The Hubble eXtreme Deep Field, our deepest view of the Universe to date, which reveals galaxies from when the Universe was only 3–4% its current age. The fact that so […]
From a Universe that went no bigger than our Milky Way to the trillions of galaxies in our expanding Universe, our knowledge increased one step at a time. “Gamow was fantastic […]
And even with them all in place, what do we still not know? “The joy of life consists in the exercise of one’s energies, continual growth, constant change, the enjoyment of […]
Something isn’t right about the Universe without something extra. So why can’t scientists agree on what that “extra” thing is? “All we know so far is what doesn’t work.” –Richard Feynman […]
Dark matter may be cold and collisionless, but the strange behavior of planets just might lead to its detection. “Few enterprises of great labor or hazard would be undertaken if […]
