A Look at The Proton’s Inner Structure Shows How Its Mass Isn’t The Same as Its Size : ScienceAlert

The humble proton is a lynchpin of the material Universe. Its characteristics define chemistry, governing teams of electrons that build atoms into molecules, and molecules into dazzling complexity.

For all we understand of its behavior, the proton’s internal structure is a chaotic mess of activity scientists are still deciphering.

A new experiment conducted at the US Department of Energy’s Thomas Jefferson National Accelerator Facility sheds light on this mystery, revealing more about proton innards and indeed how matter itself is put together at the smallest scale.

Researchers from across…
