Imagine a universe with extremely strong gravity. Stars would be able to form from very little material. They would be smaller than in our universe and live for a much shorter amount of time. But ...

One of the most exciting prospects in physics has been discovering that fundamental constants are not actually constant at all. When I first started writing, physicists and astronomers were just ...

It appears that we live on the knife-edge, where only the narrowest combination of values for the fundamental constants allow life, and especially conscious life, to arise. The fundamental constants ...

What is the meaning of life? Even the best of us couldn't hope to answer that question in a Universe Today article. But there are those who would try to "constrain" it, at least in terms of physics. A ...

One of the most dissatisfying aspects of modern physics is the fundamental constants. It's not that they are constant that bothers anyone, it is their very existence that is offensive to ...

The fundamental constants of the Universe appear to be fine-tuned with incredible precision to allow for life. The slightest variation would make our existence impossible, raising a profound question.

When we think about our Universe at a fundamental level, we think about all the particles in it and all the forces and interactions that occur between them. If you can describe those forces, ...
