There is limit to the "power" of concentration and what things it can help achieve. If meditation could help unravel the secrets of the universe, it would have helped the meditator reveal that the hardware responsible for consciousness is actually composed of neurons. All meditation might help is to remove the fog from the hall of mirror that is consciousness. To know more about the universe, one has to experiment on it and meditation can't do that.

or maybe it would reveal to the meditator that consciousness is nonlocal and what we perceive as our self is an illusion created by the systems of symbols and language which overlays our perception and through which existence filters and there is no self there is no other there is one whole and it is all conscious

It's a presumption that the universe is not a product of the mind. Without which you can not establish that the 'secrets of the universe' are not inside the mind.

I dunno man, name a scientist who doesn't concentrate.
