For every planet that orbits a star like our own, there are likely thousands of ‘orphan planets’ wandering the galaxy alone. Here in the Solar System, we can watch our star’s […]
If you want to go where no one has gone before, you have to make the investment. Here’s what last week’s launch means. If you want to send humans to Mars, […]
Perhaps energy isn’t conserved at all in an expanding Universe. If you have a Universe full of stuff — whether that’s atoms, dark matter, radiation, neutrinos, or anything else — it’s virtually impossible to […]
Neil deGrasse Tyson, famous in part for using his scientific literacy to point out flaws in TV and movies, recently criticized the good and bad science behind HBO’s Game of Thrones.
We always assume that dark matter is particle-based, and we just need to find which particle it is. But what if it isn’t so? Everything we’ve ever detected in the Universe, […]
All the answers may lie at the center of a “regular” black hole.
It’s one of the most common tropes in science fiction. But which movies actually get the science right? The way we travel through time, at a speed of one second per […]
Our best physical theories predict that a multiverse exists. But if we can’t test it, is it really scientific? The Universe is all there ever was, all there is, and […]
If we know how big the observable Universe is, why can’t we figure out how big the unobservable part is? 13.8 billion years ago, the Big Bang occurred. The Universe was […]
Science can do a whole lot of things, but proving a scientific theory is still an impossibility. You’ve heard of our greatest scientific theories: the theory of evolution, the Big […]
The differences between what you are and what you could be are stunning. The human body consists of somewhere around 1028particles, all bound together. The typical human has a mass […]
If your favorite theory made the list, you might want to consider a new favorite to bet on. “Some people believe holding on and hanging in there are signs of great […]
We’ve all heard the number: 4.5 billion years. But how do we know, and how certain are we that the Earth and Sun are the same age? Billions of years ago, […]
Dark energy is pushing distant galaxies apart from one another at an increasing rate. If the Big Rip hypothesis is true, things will only get worse from here. One of the […]
Sedna could be the very first known object from the Inner Oort Cloud. But time is running out to create and launch a mission. In 2003, scientists discovered an object beyond […]
In 1987, we detected neutrinos from another galaxy in a supernova. After a 30 year wait, we’ve found something even better. One of the great mysteries in science is determining not […]
Is science destined to crack the code of consciousness—and how would we even go about it?

When the past and future are no longer connected, some pretty weird stuff happens.
From the birth and deaths of stars to the largest structures in the Universe, Hubble shows us what we’d never see otherwise. When it comes to the Universe itself, perhaps […]
If you go all the way back to where neutral atoms first formed, you can see the cosmic microwave background. Buried in the details is the Universe’s first evidence for […]
They’re less than a billion years old. And, thanks to ALMA, they might finally pave the way to understanding how galaxies form. How do galaxies like our Milky Way come to […]
Imagine looking at one saturated pixel for years on end, and somehow learning what worlds live around it. That’s what science is for! When you think of what’s out there in […]
What happens when a good philosopher fudges the facts to promote his politics?
Many sci-fi technologies will remain in the realm of fiction unless physics changes. But some experiments could uncover just that! “Imagination makes us aware of limitless possibilities. How many of us […]
Albert Einstein’s famous thought experiments led to groundbreaking ideas.
There’s a big reason no one, not even Stephen Hawking, could fill Carl Sagan’s shoes. Everyone has a unique story to tell. For scientists, that story is one that usually only […]
Weighted blankets have been proven to help you get a better night’s sleep by mimicking swaddling and increasing serotonin levels.
Even with nothing new falling into it, our radius is increasing with every second that goes by. It’s no big secret that galaxies grow over time. The force of gravity is […]
Just because it isn’t Thanksgiving anymore doesn’t mean we don’t have an entire Universe to be thankful for. Every day, we have a choice whether we take our lives, our existence, […]
