Useful Notes: Theorum
"Theorum" is a word invented by Richard Dawkins in his 2010 book The Greatest Show On Earth as a synonym for "scientific theory," to differentiate "theory" from its usage as a synonym for "hypothesis." note 

A theorum is a scientific theory, but not just any scientific theory. While any real scientific theory has to be supported by at least some research, a theorum is a core knowledge that is supported by massive evidence and supports our basic understanding of how the universe works.

Four classic theorums are Gravity, Evolution, Heliocentrism (in the sense that the Earth revolves around the Sun rather than vice versa, not in the sense that the Sun is the center of the universe) and Round Earth (in the sense that the Earth is not flat, not in the Terry Pratchett sense that the world is flat but indeed round rather than square).

The word theorum was coined in 2009, for the purpose of distinguishing between different kinds of theories. The thing is that the word "theory" can be used in three very different ways.

  • We have the layman term "theory", which can be quite synonymous with "wild guess" or with the scientific term "hypothesis".
  • We have the scientific term "theory", which requires actual research and a good argument for why the theory is valid. However, these theories come and go and regularly replace each other as new-and-improved theories turn out to be better than the old ones.
  • Finally, we have the theorums, which get expanded over time rather than replaced. A lot has happened since the days of Newton, and many different theories regarding gravity have come and gone. But this doesn't mean that gravity itself is outdated: No, on the contrary, it gets stronger with each new calibration.

Discarding a theory is only reasonable when the research supporting it gets replaced with more accurate research. Thus, it doesn't take much to overthrow a wild guess. Any scrap of evidence is enough, and without evidence, any other wild guess is equally valid anyway. Overthrowing a regular scientific theory is more complicated, but might still be easy: Simply make a better theory and gather better evidence. Overthrowing a theorum, however, well.... In fiction, the easiest way to do that is usually to prove that reality itself is a conspiracy or that the entire mainstream scientific community is in on the same Ancient Conspiracy. While it does happen that a theorum gets disproven and eventually put on history's discard pile in Real Life, this is very rare and usually means a huge paradigm shift, such as when our civilization abandoned the geocentric worldview in favor of the heliocentric.

In fiction, theorums are generally much more fun to mess around with than general theories are. A character dismissing string theory is boring and pointless unless you are making a highly specialized science-nerd joke or similar. A character dismissing gravity as such, now that's much more interesting!
