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 ...

The figure illustrates three events in Minkowski spacetime. Event 𝐵 is neither in the past nor in the future of 𝐴, 𝐴 ∼ 𝐵, and event 𝐶 is neither in the past nor in the future of 𝐵, 𝐵 ∼ 𝐶.

The fundamental constants of nature seem perfectly tuned to allow life to exist. If they were even a little bit different, we simply wouldn't be here. Given this grave existential fact, we are forced ...

Raising the energy state of an atom’s nucleus using a laser, or exciting it, would enable development of the most accurate atomic clocks ever to exist. This has been hard to do because electrons, ...

We can never 100% prove that the constants really are constant. There is a set of very special numbers, known as the fundamental constants of nature, that cannot be explained. Where do they come from?

A group of Brazilian researchers has presented an innovative proposal to resolve a decades-old debate among theoretical physicists: how many fundamental constants are needed to describe the observable ...
