Daunting as ponders of theoretical physics might be, no harm comes from attempting to grasp their place in our reality. All it requires is willingness to imagine possibilities, nothing more than a moment of fleeting resolve dedicated to suspension of text book rational. Dipping a toe in space time’s pond isn’t intimidating, all it requires is an open mind.
Renowned physicist Richard Muller has a hypothesis – time expands because space expands, creating more space creates more time. As such, time is directional, capable only of forward movement, incapable of backward interference.
Take three minutes to hear Muller, he’ll explain better than I ever could.
