We might live in a quantum Universe, but we’ll violate the principle of relativity if space is discrete. If you try and divide matter into smaller and smaller chunks, you’ll […]

And what role, if any, does gravity play? While most of us have never had the opportunity to go into space, we all have the chance to dream about it and […]

There are three factors all competing to determine the fate of the Earth, and the one that’s winning now won’t win in the end. If you could measure the average distance […]

Your opinions about a large number of complex scientific issues are probably wrong. That’s why we have science. In 2016, an Italian virologist named Roberto Burioni was invited to appear on […]

Ending social distancing won’t only make us sicker, but will tank the health care industry in the process. The COVID-19 coronavirus pandemic continues to spread around the world. As of today, […]

It isn’t just that mass and energy are equivalent and interchangeable. It tells us something fundamental about mass itself. Of all the equations that we use to describe the Universe, perhaps […]

We’ve never found eight stars bound together in the same stable system. But nature might make it so. The Universe that we have is often more wondrous and bizarre than even […]

And if you have a friend at the same longitude, you can even measure its circumference. This year’s equinox, on March 19/20 of 2020 (longitude-dependent), is Earth’s earliest in 124 […]

Unbelievably enough, it all comes back to Pythagoras. One of the first theorems anyone learns in mathematics is the Pythagorean Theorem: if you have a right triangle, then the square […]

Few scientific ideas have been as polarizing as string theory. There are good reasons to both love it and hate it. String theory is perhaps the most controversial big idea in […]

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 […]

For over 50 years, it’s been the scientifically accepted theory describing the origin of the Universe. It’s time we all learned its truths. The Universe we know today, filled with stars […]

If dark matter is fundamentally different from the normal matter we know, there should be a way to test it. Here are the results. Dark matter — despite the enormous indirect evidence for […]

From outside a black hole, all masses take an infinite amount of time to cross the event horizon. How, then, can black holes grow? Every Milky Way-sized galaxy should contain hundreds […]

The age of the Universe is only 13.8 billion years, but we know that protons survive much longer. Here’s how. Since the discovery of radioactivity in the 19th century, humanity has […]

If you were to compress the entire history of the Universe into one calendar year, everything we love happens on December 31st. Our Universe has been around for 13.8 billion years […]

It’s not a question we know enough to know the answer to, but to dismiss the possibility is scientifically baseless. There’s one question that most of us ask at some […]

In the middle of a great cosmic void, a single, isolated galaxy persists amidst the darkness. It’s about to get a lot lonelier. Here in our own cosmic backyard, the […]

A fascinating mathematical structure exists that goes well beyond our common experience. Could it revolutionize physics? Perhaps the most remarkable fact about the Universe is that every particle within it — at […]

There’s real, straightforward science behind the destruction of an Alderaan-sized planet. In all of science fiction, perhaps the most iconic moment of destruction occurs in 1977’s Star Wars: A New […]
