True Statements About Fundamental Physics

Mouse over:

"Of these four forces, there's one we don't fully understand."
"Is it the weak force or the strong --"
"It's gravity."


Seriously, a hundred years after Einstein published his paper on General Relativity, this is still the most problematic of the fundamental forces.  The strong force (QCD) is still hard to calculate, but we think we understand it at a fundamental level.
