More than two years after JWST began science operations, our Universe now looks very different. Here are its biggest science contributions.

After 100 million nights of people asking, “What are those twinkly lights?” it is pretty remarkable that we happen to live in one of the first generations that actually knows the answer.

A group of prominent scientists shares how research has changed them.

Do we actually live in a deterministic Universe, despite quantum physics? An alternative, non-spooky interpretation has now been ruled out.

Is it groupthink? Or is there a deeper reason? In the early half of the 20th century, even after the discovery of the expanding Universe, physicists considered a wide variety of […]

In July of 2022, the first science images from JWST were unveiled. Two years later, it’s changed our view of the Universe.

When the average person has a “theory,” they’re just guessing. But for a scientist, a theory is the pinnacle of what we can achieve.

Our Solar System’s outer reaches, and what’s in them, was predicted long before the first Oort Cloud object was ever discovered.

They are expected to be cheaper to build and even more reliable than today’s nuclear plants.

Einstein’s most famous equation is E = mc², which describes the rest mass energy inherent to particles. But motion matters for energy, too.

When you mix science with speculation, you get speculation. But the underlying science is still real. Whenever you hear the phrase, “it’s just a theory,” it should trigger alarm bells in […]

Deniers will never stop misleading others. Here’s the truth. Every so often, advocates of a fringe theory — one that doesn’t fit the evidence as well as the mainstream theory — do what they can […]

When the Universe was first born, the ingredients necessary for life were nowhere to be found. Only our “lucky stars” enabled our existence.

Asking science to determine what happened before time began is like asking, “Who were you before you were born?”

Einstein’s theories of relativity faced fierce opposition. One critic claimed he was attempting to subvert the scientific method.

After years of analysis, the Event Horizon Telescope team has finally revealed what the Milky Way’s central black hole looks like.

There are a few possible solutions to the problem of interstellar travel, but they largely remain within the realm of science fiction.

Now that it’s fully commissioned, the James Webb Space Telescope begins its exploration of the Universe. Here are its first science images!

There are an estimated two trillion galaxies within the observable Universe. Most are already unreachable, and the situation only gets worse.

Drones have a lot to learn from the landing abilities of birds.

A cute mathematical trick can “rescale” the Universe so that it isn’t actually expanding. But can that “trick” survive all our cosmic tests?

Is the multiverse real? It’s one of the hottest questions in all of theoretical physics. We invited two astrophysicists to join the debate.

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, […]

The combination of charge conjugation, parity, and time-reversal symmetry is known as CPT. And it must never be broken. Ever.

Dark matter must gravitate, so why couldn’t the graviton solve it? One of the most puzzling observations about the Universe is that there isn’t enough matter — at least, matter that we know […]

There is nothing more important to science than its ability to prove ideas wrong.

Experts believe they could cut the time it takes a rocket to reach Mars by up to 25%, shaving about two months off the trip.

We confidently state that the Universe is known to be 13.8 billion years old, with an uncertainty of just 1%. Here’s how we know.

The European Space Agency’s Solar Orbiter recently captured images that could help scientists better under the mysterious physics of our Sun.

Three of our dimensions are spatial and one is temporal, but could there be more? From any point in space, you are free to move in any direction you choose. No […]
