It's fun to think about the fundamental physical constants. These are special values used in our models of the physical universe. They include things like the speed of light, the gravitational ...

Planck's constant reveals the quantum world's fundamental energy levels. It shows how light and matter exist in discrete units (quanta). This constant defines limits to our knowledge of particle ...

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.

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 ...

Through a variety of tests on Earth and throughout the universe, physicists have measured no changes in time or space for any of the fundamental constants of nature. When you purchase through links on ...

The gravitational constant is the key to unlocking the mass of everything in the universe, as well as the secrets of gravity. When you purchase through links on our site, we may earn an affiliate ...

The majority of excitatory synapses in the brain uses glutamate as neurotransmitter, and the synaptic transmission is primarily mediated by AMPA and NMDA receptors in postsynaptic neurons. Here, we ...
