Dark Matter
From the tiniest subatomic scales to the grandest cosmic ones, solving any of these puzzles could unlock our understanding of the Universe.
The theory is accurate within at least one part in a quadrillion.
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.
Our model of the Universe, dominated by dark matter and dark energy, explains almost everything we see. Almost. Here's what remains.
The key problem with the dark matter hypothesis is that nobody knows what form dark matter might take.
There's an extra source of massive "stuff" in our Universe beyond what gravitation and normal matter can explain. Could light be the answer?
Searching for dark matter, the XENON collaboration found absolutely nothing out of the ordinary. Here's why that's an extraordinary feat.
Even with only 12.5 hours of exposure time, James Webb's first deep-field image taught us lessons we've never realized before.
No matter how beautiful, elegant, or compelling your idea is, if it disagrees with observation and experiment, it's wrong.
The Standard Model of elementary particles has three nearly identical copies of particles: generations. And nobody knows why.
On July 12, 2022, JWST will release its first science images. Here are 5 ways the telescope's findings could change science forever.
Over time, the Universe becomes less dominated by dark matter and more dominated by dark energy. Is one transforming into the other?
Do the laws of physics place a hard limit on how far technology can advance, or can we re-write those laws?
Popular media often frame scientists as having a cold, sterile view of the world. That couldn’t be further from the truth.

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.
Dr. Tyson explains where we might find aliens, why "dark matter" is a misleading term, and why you can blame physics for your favorite team's loss.
For some reason, the charges on the electron and proton are equal and opposite, and their numbers are equal, too. But why?
In the latest edition of the Starts With A Bang podcast, we talk with soon-to-be Dr. Arianna Long about galaxies, from birth to today.
Our Universe requires dark matter in order to make sense of things, astrophysically. Could massive photons do the trick?
To answer any physical question, you must ask the Universe itself. But what happens when the answers aren't around anymore?
Even a tiny sliver of the Universe can reveal the cosmic story of what's out there and how it came to be the way it is today.
The laws of physics state that you can't create or destroy matter without also creating or destroying an equal amount of antimatter. So how are we here?
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?
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.
Out of all the galaxies we know, only a few little ones are missing dark matter. At last, we finally understand why.
With 1550 distinct type Ia supernovae measured across ~10 billion years of cosmic time, the Pantheon+ data set reveals our Universe.
The Universe is supposed to be the same everywhere and in all directions. So what's that giant "cold spot" doing out there?
Hubble's deepest views of space revealed fewer than 10% of the Universe's galaxies. James Webb will change that forever.
Shooting star or piece of space dust?
We frequently say it's 2.725 K: from the light left over all the way from the Big Bang. But that's not all that's in the Universe.
