preprint description
As there have still been attempts to regard gravity, a 100 years after Einstein's general relativity, not as a manifestation of the non-Euclidean geometry of spacetime, but as a physical field (and therefore as a force), it is high time to face the ultimate judge -- the experimental evidence -- to settle this issue once and for all. Two rulings of the ultimate judge are reminded -- (i) the experimental fact that falling particles do not resist their fall rules out the option that gravity may be a force, and (ii) the experiments that confirmed the relativistic effects are impossible in a three-dimensional world, which also implies that gravity is indeed manifestation of the geometry of the real spacetime. It is also stressed that not only are attempts to impose a kind of scientific democracy in physics doomed to failure (because the question of what the external world is, is not necessarily determined by what the majority of physicists claim), but such attempts might, in the end, hamper the advancement of fundamental physics.
