Back in 2005 (Christmas Eve, in fact), I posted “Einstein was right (again)”, pointing to a EurekAlert post confirming NIST and MIT had confirmed the famous mass-to-energy equation.
Now I hear a team consisting of French, German and Hungarian physicists have confirmed this (again).
Not sure who was first (but three years is a bit of a gap, to be sure).
From the more recent post:
According to the conventional model of particle physics, protons and neutrons comprise smaller particles known as quarks, which in turn are bound by gluons.
The odd thing is this: the mass of gluons is zero and the mass of quarks is only five percent. Where, therefore, is the missing 95 percent?
The answer, according to the study published in the US journal Science on Thursday, comes from the energy from the movements and interactions of quarks and gluons.
In other words, energy and mass are equivalent, as Einstein proposed in his Special Theory of Relativity in 1905.
Here are links to both posts, for those who need to confirm:
Of course, this only proves that a quantity of energy can be converted from a quantity of matter, and that a quantity of matter can be converted from a quantity of energy .. not that the latter has been performed.
