Actually (and thanks for flattering), Flash's ability is more scientific than one might think. It works with string theory, and it is quite a complex thought. I'm not going to explain it whole here, but he basically changes the frequency of strings that, according to the string theory, are fundamental particles of matter, to be different than the frequency of the membrane that his reality is on. This allows him to shift between alternate universes and yeah, also to become "intangible". (ImaginaryAxis has a good video on it: https://www.youtube.com/watch?v=ZGDoIFvVAwM)
