What if the Universe Stopped Expanding—and Started Shrinking?
Imagine this: the universe, instead of endlessly expanding, suddenly begins to collapse. What would that even look like? Galaxies, instead of drifting apart, would start racing toward each other. Temperatures would skyrocket, and the once-peaceful night sky would become a battlefield of colliding stars and galaxies. Over time, the universe could shrink into a superdense, blazing-hot core. Could this lead to the ultimate cosmic implosion—a singularity? Or even stranger, could the universe be setting the stage for a rebirth, another Big Bang?
While this "Big Crunch" idea sparks curiosity, current evidence shows the universe is expanding faster, not slowing down. So, is a contraction out of the question, or does the universe have more surprises in store for us?#physics #science #cosmos
