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 […]

No. No no no. Just… no. The JWST has truly blown our scientific minds, but it’s a pure crackpot idea that the Big Bang is now disproven.
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.
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. […]
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 […]
Scientists have been chasing the dream of harnessing the reactions that power the Sun since the dawn of the atomic era. Interest, and investment, in the carbon-free energy source is heating up.
Developing an awareness of and an appreciation for science is what we all truly need, not what we’ve been doing.
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.
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 […]
A thought experiment from 1867 leads scientists to design a groundbreaking information engine.
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?
Is the physical universe independent from us, or is it created by our minds, as suggested by scientist Robert Lanza?
From hellishly hot planets to water worlds, some distant planets are like nothing in our Solar System.
The Standard Model of elementary particles has three nearly identical copies of particles: generations. And nobody knows why.
The controversy over the universe’s expansion rate continues with a new, faster estimate.
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, […]
New studies find the interstellar comet 2I/Borisov is the most “pristine” ever discovered.
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 […]
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.
The most unique interloper into our Solar System has a natural explanation that fits perfectly — no aliens required.
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 […]
The changes in brain structure aren’t the only bodily changes caused by zero gravity.
There was less than a 2 second delay between gravitational waves and light, but that’s incredibly meaningful. There’s an important rule in relativity that — as far as we know — all objects must […]
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 […]
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.
It might not feel that way, but a 95% dark Universe really is the best game in town. No matter how much we might try and hide it, there’s an enormous […]
For some reason, the charges on the electron and proton are equal and opposite, and their numbers are equal, too. But why?
The inevitable long, slow decline is accelerating, and there’s nothing we can do. The Universe, as it is today, is less active, is forming fewer stars, and is creating fewer chances […]
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 […]
