@Lithe I agree.
@tripledraw Yeah it's looking very very likely at this point, and if Souichi can use Echolocation he probably also has very enhanced hearing, so you might be right on that one as well.
@oka-tan "In Einstein's general theory of relativity, gravity is treated as a phenomenon resulting from the curvature of spacetime. This curvature is caused by the presence of mass. Generally, the more mass that is contained within a given volume of space, the greater the curvature of spacetime will be at the boundary of its volume.[16] As objects with mass move around in spacetime, the curvature changes to reflect the changed locations of those objects. In certain circumstances, accelerating objects generate changes in this curvature, which propagate outwards at the speed of light in a wave-like manner. These propagating phenomena are known as gravitational waves."
"In 1922, he was awarded the 1921 Nobel Prize in Physics "for his services to Theoretical Physics, and especially for his discovery of the law of the photoelectric effect".[10] While the general theory of relativity was still considered somewhat controversial, the citation also does not treat even the cited photoelectric work as an explanation but merely as a discovery of the law, as the idea of photons was considered outlandish and did not receive universal acceptance until... "
Perhaps saying they were considered occultism was a bit of an exaggeration, but even though Einstein was already respected by that time (more like they had no choice but to respect him), most of his crazier ideas were still very controversial especially when first introduced. In fact, the discovery of gravitational waves experimentally happened fairly recently, so it's fair to say that not everyone was sold.
