Vácuo quântico
Aquilo que escrevi numa série de postais com o título genérico “Thomas Huxley estava errado” confirma-se:
Matter is built on flaky foundations. Physicists have now confirmed that the apparently substantial stuff is actually no more than fluctuations in the quantum vacuum.
The researchers simulated the frantic activity that goes on inside protons and neutrons. These particles provide almost all the mass of ordinary matter.
Each proton (or neutron) is made of three quarks – but the individual masses of these quarks only add up to about 1% of the proton’s mass. So what accounts for the rest of it?
