Before Big Bangs - Yes, Big Bangs, Thanx Prof Penrose

I Think of a huge pond or lake. It's been raining. While ripples fall and send their concentric circles further and further, you no longer see individual ripples and circles. Although it's now a confusing criss-cross of space and time, you can track back to the individual raindrop that started each ripple - backwards in time. That's the way to understand what was before each Big Bang. II Why would there be only One Big Bang? One singular event that altered the thermal equilibrium? Especially since we have the Second Law of thermodynamics implies the universe becoming more and more random from where it began. So, going backwards in time we get to: a. No randomness b. No time ( the universe forgets both time/speed and even how big it is). c. The analogy of raindrops hitting the lake surface ( space-time canvas?) may now replace the raindrops with BLACK HOLES. The black hole in our Milky Way will collide with the ripples of another black hole in an expanding universe, where the "ripples" also keep going out further and further. But so are the other "ripples" in the universe. Hence, big Bangs.
