If the idea comes from philosophy or pure speculation it could be considered a theory. It depends on its use and context.
Indeed. And if the context is a website devoted to science (this is, after all,
SCIforums), we should use the scientific definition. Even in History and Arts & Culture. These are supposed to be
scientifically-oriented discussions of history and arts & culture. Anybody who wants a different perspective can Google a hundred websites of that nature in a few seconds.
Since I am not a real scientist doing real scientific work on internet forums, I would think that would validate the use of the word theory.
You many not be a real scientist, but you are on a science website. You're expected to comport yourself like a scientist. That's one of the things we
expect our members to learn here, as a bare minimum.
A philosophical principal would always be considered a theory.
Not on a science website. And I think you meant "principle," not a voting partner in a consulting firm.
So then they will never call The Big Bang Theory, The Big Bang Law even though they have proven that the universe is expanding.
A law is simpler than that. It can often be expressed as a single equation, such as Avogadro's Law: pV=nRT. Laws are developed to explain an entire family of phenomena. The Big Bang was a singularity, so we don't need a law to explain it.
The Second Law of Thermodynamics goes a long way toward explaining the Big Bang. It says only that entropy
tends to increase over time. It clearly allows spatially and temporally local reversals of entropy. Since the Big Bang resulted in a balance of matter and anti-matter, etc., nothing was
created. All that happened was an increase in
organization, i.e., a spatially and temporally local reversal of entropy.
As it is suggested that is all The Big Bang Theory "is", even though the name itself comes from the idea of an initial explosion. Then not being able to determine the cause of the initial explosion, it will remain a theory.
The explosion was simply the predictable result of all that matter and antimatter coming into existence in one point of space and time. The
cause of the explosion was a local reversal of entropy. We observe local reversals of entropy every day. Every living creature is a local reversal of entropy: extracting the organization from its surroundings (for example, killing other living things) in order to increase its own organization (digesting the tissue of the other living things to become larger, faster, etc.) Since the increase in the predator organism's organization is of smaller magnitude than the decrease in the prey organism's organization (the prey dies; the predator merely survives), one does not have to expand the horizon of the observation very far to find that the entropy of the universe as a whole has increased.
Then the "String Hypothesis" is still just String Theory, as it is only mathematical abstractions.
Science deals with reality, so in science, a theory is a hypothesis that has been proven true beyond a reasonable doubt. Mathematics deals exclusively with abstractions, so in mathematics a theory is a hypotheses that has been proven
absolutely true, such as 1+1=2.
Nonetheless, string "theory" is not meant to be abstract mathematics. It is meant to explain
how reality works. This puts it outside the realm of mathematics, so it only needs to be proven true beyond a reasonable doubt. To date, that proof has not taken place, so it is still only a hypothesis.
I agree with you that you shouldn't judge a "theory" by its cover, as most of the names of "theories" that have the word "theory" in them does not necessarily mean that it can only be considered as being a true "theory" by scientific standards.
Indeed. Nonetheless we should clean up our act. The spawn of the Religious Redneck Retard Revival insist that since
evolution is "only a theory," uneducated laymen who believe in the supernatural phenomena described in the Bible have a perfect right to challenge it.
Saying that something is only a theory is fail in most religious debates as science doesn't really care to change the name of theories that have the word theory in them.
The world will never be a safe place for scholarship so long as the Stone Age phenomenon of religion remains with us.
We don't call it the "Law of Relativity", although I wonder if we would if we never discovered dark matter.
Scientists use "theory" when they mean "hypothesis," so when the hypothesis is finally proven true beyond a reasonable doubt, they still have nothing else to call it but a "theory." As I have complained often, scientists are absolutely shitty communicators.
As for the impact of the discovery of dark matter (and dark energy), you'll have to take that question to the Math & Physics subforum, where there are some genuine scientists yearning for the chance to answer it. And of course since these are our guys, they are splendid communicators.
