Although most of the Universe’s mass is dark matter, which gravitates just as well as normal matter, it still can’t make black holes.
Developing an awareness of and an appreciation for science is what we all truly need, not what we’ve been doing.
The Standard Model of elementary particles has three nearly identical copies of particles: generations. And nobody knows why.
If dark matter exists in a large halo in our galaxy, made up of particles, then it’s passing through us constantly. But how much?
Filaments, hundreds of millions of light-years long, were just caught spinning. In our own cosmic backyard, everything we see spins, rotates, and revolves in some fashion or other. Our planet […]
There’s a big difference between the notions of ‘false vacuum’ and ‘true vacuum’ states. Here’s why we don’t want to live in the former.
Time travel is possible, but only in one direction.

When you view your right hand in a mirror, it appears as a left hand. Writing is reversed, as is the direction of any spinning object: clockwise becomes counterclockwise and […]
Only 17 years after its discovery have we learned we’re safe from asteroid Apophis. Ever since its 2004 discovery, asteroid 99942 Apophis has threatened planet Earth. Asteroid Apophis has been measured […]
From hellishly hot planets to water worlds, some distant planets are like nothing in our Solar System.
Just say no to artist’s illustrations. This is what the Universe actually looks like. The Universe we observe often surpasses our greatest imaginings. This 20-year time-lapse of stars near the center […]
Are dark matter and dark energy both two sides of the same coin? When it comes to the Universe, what you can easily see isn’t always reflective of all there is. […]
A thought experiment from 1867 leads scientists to design a groundbreaking information engine.
Is the physical universe independent from us, or is it created by our minds, as suggested by scientist Robert Lanza?
It might have been Einstein’s greatest blunder, but it’s our leading theory today. One of the most mysterious components in the entire Universe is dark energy, which — if we’re being honest with […]
Yes, we’d all die. But for 21 minutes, we’d have the ride of a lifetime. One of the most remarkable facts about the Universe is this: in the absence of […]
Despite all the challenges, Hubble has vindicated this discovery. Practically everywhere we look in the Universe, the large-scale objects that we see — small galaxies, large galaxies, groups and clusters of galaxies, […]
The most unique interloper into our Solar System has a natural explanation that fits perfectly — no aliens required.
The controversy over the universe’s expansion rate continues with a new, faster estimate.
When we look out at the Universe, even with Hubble, we’re only seeing the closest, biggest, brightest galaxies. Here’s where the rest are.
The universe is only 13.8 billion years old, but we can see back 46.1 billion light-years. Here’s how the expanding universe does it.
For some reason, the charges on the electron and proton are equal and opposite, and their numbers are equal, too. But why?
The pendulum didn’t tick right when they brought it here: the start of a fascinating story. For nearly three full centuries, the most accurate way that humanity kept track of […]
New studies find the interstellar comet 2I/Borisov is the most “pristine” ever discovered.
We have to use the right definition for the specific question we’re asking. When it comes to the Universe, we frequently characterize objects by examining and reporting on their physical […]
Look out at a distant object, and you’re not seeing it as it is today. It’s size, brightness, and actual distance are all different.
It could have had any curvature at all. So why is it flat? What is the shape of the Universe? If you had come along before the 1800s, it likely never […]
Why does dark matter, if it doesn’t dissipate energy, become gravitationally bound at all? One of the most puzzling components of the Universe has to be dark matter. Although we have […]
