A new paper making big waves says that the cosmos is 26.7 billion years old. The catch? It relies on phenomena we've never seen before.

We're taught that our universe looks and works the same way in every direction. That may not be entirely true.

The universe may be the way it is today because the physics of matter and antimatter work just a bit differently...

Stephen Wolfram joins a long line of theoreticians who believe they uncovered how the universe really works. He, like all of them, is almost certainly wrong.

It turns out that one of the oldest objects in the known universe is only a few thousand light years from Earth.

We're here for an exciting time, not a long time. And we should use that time doing something fun and constructive.

Continuing the trend of looking too closely to CMBR maps, a group of cosmologists says they found evidence of "bruises" from collisions with other universes.

While many physicists are trying to dive deeper and deeper into the complexities of space and time, others are looking for a much simpler explanation of the universe's mysteries.

If our universe is one of many, just how many others are out there? A duo of physicists try to answer that question. Well, sort of...

No matter what we try, we can't get around the need for dark matter in our equations and observations.

The oft-cited anthropic principle is a useless tautology.

Add another bizarre, universe-defining darkness to your list.
