What If the Universe Starts Shrinking?

This isn't the first time you've pondered this question. Imagine the Universe not expanding but shrinking, with spacetime contracting until it forms a singularity smaller than a YouTube Like button. After collapsing, there's a possibility it could explode outward, similar to a supernova, creating a new universe. This could be the 'Big Bounce' instead of the Big Bang, potentially occurring countless times. Explore if the Universe starts shrinking and understand the implications on cosmic phenomena.
