A cyclical theory for the fabric of spacetime , is this universe cyclical ? multiverse excluded . The Hindu religion believes in "yugas" or ages that span 4.32 billion years .These ages repeat themselves in a cyclical fashion . Also They believe that time is relative, years before Einstein produced his theory. What if the larger scale of our universe was finite but cyclical in nature ; like a vast flowing fountain with an in and out supermassive black hole to a supermassive white hole and back again .
