In the 20th century, many options abounded as to our cosmic origins. Today, only the Big Bang survives, thanks to this critical evidence.

The $21.5-billion project could involve tunneling hundreds of feet under Lake Geneva.

The first observational evidence showing the Universe is expanding is 100 years old now: in 2023. Here’s the story of its 100th anniversary.

There are a few clues that the Universe isn’t completely adding up. Even so, the standard model of cosmology holds up stronger than ever.

If you’ve found yourself befuddled by extraordinary scientific-sounding claims, you’re not alone. But this centuries-old lesson can help.

A community in Austin, Texas is using geothermal energy to keep homes warm in the winter and cool in the summer.

Jotform CEO Aytekin Tank outlines a strategy for balancing collaboration with healthy competition.

The Reitoff principle gives us permission to “write off” a day and intentionally step away from achieving anything.

What do ghosts and anomalous galaxy rotation rates have in common? Some sci-fi enthusiasts believe the answer involves “parallel universes.”

Now they’re pointing the way to future battery technologies.

The double-slit experiment, hundreds of years after it was first performed, still holds the key mystery at the heart of quantum physics.

This technological feat changes our cosmic history.

Lasers are all around you. This ubiquitous technology came from our understanding of quantum physics.

We live in a four-dimensional Universe, where matter and energy curve the fabric of spacetime. But time sure is different from space!

No matter what physical system we consider, nature always obeys the same fundamental laws. Must it be this way, and if so, why?

The site will be the first working example of a geological disposal facility.

We’ve heard this argument before.

Yes, “the laws of physics break down” at singularities. But something really weird must have happened for black holes to not possess them.

The great hope is that beyond the indirect, astrophysical evidence we have today, we’ll someday detect it directly. But what if we can’t?

The idea of gravitational redshift crossed Einstein’s mind years before General Relativity was complete. Here’s why it had to be there.

For many years, cosmologists have claimed the Universe is 13.8 billion years old. A new paper says no, it’s 26.7 billion. How do we decide?

2023 is an exciting time for the study of quark-gluon plasmas.

Even with the quantum rules governing the Universe, there are limits to what matter can withstand. Beyond that, black holes are unavoidable.

Could Russia’s plan actually destroy demand for natural gas?

In revolutionary Russia, a group of forward-thinking philosophers offered an alternative to both futurism and communism.

Supermassive black holes at the centers of galaxies gobble up whatever matter ventures too close, becoming active. Here’s how they work.

Discrepancies between observations and theory regarding subatomic particles called muons may force scientists to rethink the quantum world.

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.

Over 50 years since humans last walked on the Moon, astronaut footprints and rover tracks are still visible. But they won’t last forever.

Tech designed to fuse atoms might be able to clean up space, too.
