e=mc2: 103 years later, Einstein's proven right
Interesting stuff.

"Until now, this has been a hypothesis," France's National Centre for Scientific Research (CNRS) said proudly in a press release.
"It has now been corroborated for the first time."
For those keen to know more: the computations involve "envisioning space and time as part of a four-dimensional crystal lattice, with discrete points spaced along columns and rows."
I believe that the yields of nuclear reactions have long since been calculated using e=mc^2 and the results have always been consistent. I haven't read it yet but I assume that this is an attempt at a formal, logical proof (the gold standard) rather than experimental verification.

Yeah now that I've read the article I would agree, but I'm curious as to whether this amounts to a proof or if it is just a postulate or corollary that agrees with the theory. I'll have to do some reading. The article is not that helpful.

The Theory of Relativity will forever remain a theory, much like the Theory of Evolution, Atomic Theory or Game Theory.
The reason is that 'Theory' in the scientific sense does not mean the same thing as 'theory' used in the colloquial sense.
Here's a definition of what constitutes a Theory:
Quote:
A theory is an explanation of a set of related observations or events based upon proven hypotheses and verified multiple times by detached groups of researchers. One scientist cannot create a theory; he can only create a hypothesis.
In general, both a scientific theory and a scientific law are accepted to be true by the scientific community as a whole. Both are used to make predictions of events. Both are used to advance technology.
In fact, some laws, such as the law of gravity, can also be theories when taken more generally. The law of gravity is expressed as a single mathematical expression and is presumed to be true all over the universe and all through time. Without such an assumption, we can do no science based on gravity's effects. But from the law, we derived Einstein's General [COLOR=blue! important][COLOR=blue! important]Theory [COLOR=blue! important]of [/COLOR][COLOR=blue! important]Relativity[/COLOR][/COLOR][/COLOR] in which gravity plays a crucial role. The basic law is intact, but the theory expands it to include various and complex situations involving space and time. The biggest difference between a law and a theory is that a theory is much more complex and dynamic. A law governs a single action, whereas a theory explains an entire group of related phenomena.
That article made my head hurt. I was never good at science.

I think the laymans terms version of this is, protons and neutrons are made up of smaller stuff. 5% of this stuff is actually matter, what the hell happened to the other 95%? These computer and math nerds found that yes, that 95% is Energy. E=mc2, c is a constant so the equation are saying energy and mass are the same thing, and this article is verifying that with rest of the 95% stuff.
For some reason, I thought this was already proven and well known already.

The Following User Says Thank You to Phanuthier For This Useful Post:
Just in case you were wondering, Einstein published these papers in 1905 when he was 26 years old (although they were a continuation of work he had started when he was 16). In the same year he published some other papers--one in which he described energy quanta (which he called photons) for the first time, and another in which he described Brownian motion which helped found the modern concept of the atom.

What did you do when you were 26?
Well I've been 26 for a while now and I've had many Brownian motions.
