Yeah, matter may look solid, but secretly it is an open structure linked into the grand overall design of our reality. It is merely extremely condensed energy which feels solid to the touch, even though it is almost all empty space (or so they say)
In reality though, that "empty" space is filled to the brim with energy, so much so that we would be totally abundant if we could harness it all. Over the years many have tried, and some have succeeded, but there are numerous stories where those who succeeded were never heard from again, leading to just as many conspiracy stories.
Is this knowledge actively being suppressed? Perhaps, but I urge you to do your own digging, and make your own conclusions, because that will convince you far better than I ever could!
