Forwarded post:
Shocker (not). Im also figuring its a matter of time (possibly soon, considering this post) before they figure out that light isnt actually the speed limit, light has mass, and that dark matter/energy doesnt exist because it isnt needed to satisfy their observations.
Addressing the universe mathematically will teach you an awful lot, but it doesnt solve everything. I believe its a forest for the trees problem.
Of course, to a mathematician Im an unqualified boob  but its not the first time Ive sat back and said well duh at one of these discoveries.
