What about the ? ...People have done studies in outer space of astronauts and how long they could survive in the vacuum... That information say that … - Suzie Sheehy

Our view of the smallest constituents in nature has changed rapidly in the last 120 years... Some way into the twentieth century this work became known as "high-energy physics,"... Today the study of all the many particles and how they formed, behave and transform is simply called particle physics.

I'd just been asked by four particle physics professors... my PhD interview was conducted over an unstable internet connection... "what do you find fascinating about particle physics?" ...I told them of my wonder at the way physics seemed to be able to describe everything: from the smallest s to the atoms that make up our bodies, up to the largest scales of the Universe, and how all of this was connected.
Particle physics, I said, was the foundation of it all.

That's only one particle accelerator. There are actually over 26,000 of them in the world.
