Hi again. In relation to previous response, I've just come across this in a Medium article: "Penrose, based at the University of Oxford , has developed a rival theory known as 'conformal concyclic cosmology' (CCC) which posits that the universe became uniform before, rather than after, the Big Bang. The idea is that the universe cycles from one aeon to the next, each time starting out infinitely small and ultra-smooth before expanding and generating clumps of matter. That matter eventually gets sucked up by supermassive black holes, which over the very long term disappear by continuously emitting Hawking radiation. This process restores uniformity and sets the stage for the next Big Bang".

This fits precisely with the Hindu idea.
