How can the behavior of elementary particles and the structure of the entire universe be described using the same mathematical concepts? This question is at the heart of recent work by the ...

When you look at your surrounding environment, it might seem like you’re living on a flat plane. After all, this is why you can navigate a new city using a map: a flat piece of paper that represents ...

Here’s what you’ll learn when you read this story: Mathematical evidence indicates that our universe is flat, but it could be infinitely big, as well. You can figure out if an object is flat with a ...

So cosmologists feel confident in modelling the universe using the “maximally symmetric” description of space-time in Einstein’s theory of general relativity. This symmetric vision for the universe, ...

There is a set of very special numbers, known as the fundamental constants of nature, that cannot be explained. Where do they come from? Finding out if they are, in fact, constant is the key to ...

Neutrino particles have extremely small masses, yet there are so many of them that they carve out the large-scale structure ...

Is the universe infinite? It's one of the most profound questions we can ask, and here's the short answer: We don't know. While we have learned a great deal about the universe, a portion of the cosmos ...
