Why string theory requires extra dimensions

String theory found its origins in an attempt to understand the nascent experiments revealing the strong nuclear force. Eventually another theory, one based on particles called quarks and force carriers called gluons, would ...

The miraculous effect of music: Concerts bind people together

Why does music exist? Some researchers believe that music is so widespread across human cultures because it brings people together. The theory is that during evolution, human groups who were musical worked better together, ...

How to think about a four-dimensional universe

In Einstein's famous theory of relativity the concepts of immutable space and time aren't just put aside, they're explicitly and emphatically rejected. Space and time are now woven into a coexisting fabric. That is to say, ...

Pulsars may make dark matter glow

The central question in the ongoing hunt for dark matter is: what is it made of? One possible answer is that dark matter consists of particles known as axions. A team of astrophysicists, led by researchers from the universities ...
