"The strong force that binds quarks inside hadrons is carried by another kind of tiny elementary particle called gluons, which are exchanged between the quarks. To separate individual quarks requires an enormous amount of energy (it's not called the strong force for no reason). This amount of raw energy only existed in nature about 10 billionths of a second to about a millionth of a second after the Big Bang, when the temperature was approximately 3.6 trillion degrees Fahrenheit (2 trillion degrees Celsius)"

How do they know that?

Musings: If there are such things as subatomic particles, couldn't there also be a super universal field where multiple universes are expanding and contracting, not just our own?
Hmmm.....

Perhaps the easiest analogy is that it’s like investigating a car crash.

They crash particles together and look at the parts. They can measure masses, charges, momentum, energy etc. for each particle and use equations to figure out how tightly the parts were held together before the crash.

It’s always a matter of designing experiments to improve equations and designing equations to match experiments. Back and forth over decades and centuries until it’s all consistent.

... and then there's the tachyon rocket, which returned itself before I launched it.
