Although I didn't discuss this point in the video, I've realized Dark Matter may not be "Matter" at all. Presently, scientists THINK Dark Matter is a massive particle which doesn't interact via the three other known force laws, but does use Gravity. Personally, I think Dark Matter uses an entirely unknown force law, and therefore can't necessarily be assumed to be "gravitational mass".
Additionally, as I discuss in the video briefly, there may be substances/entities in the Universe which are neither a particle nor a wave, such as "Solids" and "surfaces". In string theory, "Branes" or "Membranes" are hyper-dimensional surfaces which are neither particle nor wave. So I like the fact string theory admitted there may be substances other than particles or waves. There are seven known "force laws" in the Universe, but we've only correctly mathematically described four of those seven laws. See video and I explain why I believe there are 11 physical force laws and 11 miraculous laws.
because "matter" is a missconception we're all taught. there's no matter. everything is a wave. like light and sound.
