It would mean that some of our fundamental understanding of nature is incorrect and needs to be modified. What Maris has proposed is that loose electrons in ultracold liquid helium might split into fragments when exposed to light. In accordance with quantum mechanics, he pictures the electron as a wave that fills the bubble. Maris' calculations show that the bubble could elongate and narrow at its waist, finally splitting into two new bubbles. The shocking part for physicists is that the electron would also split in two, dropping a chunk into each daughter bubble.
Physicists are a long way from accepting the new idea.
One reason for hearing Maris out is that his theory appears to solve a long-standing mystery. Experiments on liquid helium dating back to the 1960s produced puzzling results. Scientists have offered various explanations for the results, including the presence of unknown impurities. Accounting for the overall boost in current, Maris calculates that electrino bubbles would experience less drag from the liquid because of their small size. As for the exotic ions, he argues that there could be a plethora of different-size electrino bubbles with different speeds.
