The laws of physics aren’t changing. The Earth is. When it comes to any physical science, we know that the fundamental rules governing how the Universe works remain constant with time. […]

Something isn’t adding up, but it isn’t a calibration error. It’s been nearly 100 years since we discovered that the Universe was expanding. Ever since, the scientists who study the […]
It’s fundamentally different from space. Here’s how. Here’s a question that most of us have been asked at some point in our lives, “what’s the shortest distance between two points?” By […]
How can we save humanity from ourselves? In this life and this Universe, there will always be questions beyond the capabilities of humanity to answer. There’s so much that we’ve […]
How a controversial study on psychic powers caused a revolution in psychology research.
The expansion rate is dropping, but distant galaxies are accelerating. Here’s how. If you take a look at any galaxy in the Universe that isn’t gravitationally bound to our own, we’ve […]
It happened more than once, and needed to. Here’s why. If there’s one thing you can be certain about when it comes to outer space, it’s that it’s transparent, not opaque, […]
Many people, including some scientists, fear that the coming 5G WiFi revolution will harm humans. Here’s why that’s unfounded. Over the coming few years, a new set of infrastructure will […]
Map shows oldest buildings for each U.S. state – but also hints at what's missing.
The first Earth-sized planet without a parent star has just been discovered. For countless millennia, planets beyond our Solar System were mere speculation. Today, we know of over 4,000 confirmed […]
If a large asteroid strikes Earth, it has the potential to release an enormous amount of energy, leading to local or even global catastrophes. The strike that led to the […]
A question that's baffled physicists for nine years has been resolved by the simplest possible answer.
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 […]
Could this finally be the clue we’ve hoped for in uncovering the truth about dark matter? In the physical sciences, theory and observation are supposed to work hand-in-hand. Theorists work out […]
Here are the best answers science has to a myriad of commonly asked questions. Over the past 12 months, the status of humans on planet Earth has changed dramatically. The […]
It doesn’t propagate at infinite speeds, and that’s a problem for Newton. When you look at the Sun, the light you’re seeing isn’t the light that’s being emitted right now. Instead, […]
With just a few more neutron star mergers, we’ll have the best constraints of all-time. How fast is the Universe expanding? Ever since the expanding Universe was first discovered nearly […]
We know what effective teaching looks like. Implementing it can change the lives of Americans.
How can you "touch the Sun" if you've always been inside the solar corona, yet will never reach the Sun's photosphere?
Two stellar mass black holes, if they merge in the vicinity of a supermassive black hole, could have their gravitational wave signal affected by the strongly curved space around them. […]
With launch costs dropping and enormous numbers of new satellites filling the sky, can't we just do it all from space?
It’s absolutely true that atoms are mostly empty space. But removing even that empty space is impossible, and this is why. If you were to take any object in the Universe […]
Complex organisms and living worlds couldn’t exist without these transitions. You couldn’t make the Universe we have today if everything were always the same. Although many philosophically favored the idea […]
What could be better than "do unto others as you would have others do unto you"?
It’s not the only one of its kind, but it’s definitely makes no sense without dark matter. Throughout the Universe, galaxies and star clusters come in all different sizes and masses. […]
Here's a look at the space agency's astronaut candidate requirements.
Of all the injustices in Nobel Prize history, her 1957 Nobel snub is the most egregious. One of the biggest scientific revolutions of the 20th century was the discovery of […]
Using atoms to probe the Universe reveals the complete Standard Model. If you wanted to uncover the secrets of the Universe for yourself, all you’d have to do is interrogate […]
