The Mass Problem Physicists Are Still Desperately Trying to Solve

#physics #mass #higgs What are you actually holding when you lift something heavy? This calm, two-hour deep dive follows one idea all the way to the bottom, from the everyday feel of weight to the deepest open questions in physics. We trace mass from Newton's stubborn inertia and the strange equality of falling bodies, through Einstein's discovery that mass is energy, into the atom and the proton, where the strong force conjures ninety-nine percent of your weight out of pure binding energy. Then to the Higgs field that gives fundamental particles the rest, the long hunt for the Higgs boson, and the puzzles still unsolved: the arbitrary ladder of masses, the weightless neutrino that turned out to weigh something after all, the fine-tuning of the Higgs, the dark matter that outweighs the stars, and the worst prediction in physics, the weight of empty space itself.
