We experience the flow of time because it’s a natural outcome of the basic laws of physics. But we may need to build a whole new model to account for gravity’s influence.

For years, the James Webb Space Telescope has been spotting enormous black holes in the early universe that defy all ...

To explain these observations, they proposed a new kind of energy that is responsible for driving the universe’s accelerated expansion: dark energy. Astrophysicists now believe dark energy makes up ...

Astronomers have confirmed the earliest barred spiral galaxy in the universe, a Milky-Way-like structure that existed just 2 ...

How many electrons are there in the Universe? One bold theory suggests that there could only be one, although this theory has ...

The Subaru Telescope discovered a unique quasar that was shining bright in two kinds of waves despite its continuous growth.

The Universe may not have started with the Big Bang, but instead “bounced” out of a massive black hole formed within a larger “parent” universe, according to a new scientific paper. Professor Enrique ...

Nearly everything in the universe is made of mysterious dark matter and dark energy, yet we can’t see either of them directly. Scientists are developing detectors so sensitive they can spot particle ...

The fate of the cosmos may be a bit different than previously expected. For years, scientists have talked about how the universe is always expanding — constantly moving outward, never stopping.

Wormholes are often imagined as tunnels through space or time—shortcuts across the universe. But this image rests on a ...

For decades, astronomers have been trying to nail down the value of the Hubble constant—a measure of how fast the universe is expanding. But some cosmologists say there’s evidence that the universe is ...

This December, the SciFri Book Club will read The Biggest Ideas in the Universe: Space, Time, and Motion by Sean M. Carroll. This New York Times bestseller transforms intimidating physics equations ...
