What If Physics Worked Differently in Another Universe?

What if the speed of light wasn’t constant? What if gravity was ten times stronger? This video explores the fascinating idea of alternate universes where the fundamental laws of physics are completely different from our own.

We dive into how changes in physical constants like the speed of light (c) and the gravitational constant (G) could dramatically reshape the universe. How would stars form? Would black holes be more common? Could life as we know it even exist?

From time dilation and atomic structure to star formation and black hole physics, we examine how slight changes in physical laws could lead to entirely unfamiliar realities.

This is not just science fiction—it’s a real scientific thought experiment that helps us better understand why our universe works the way it does, and what it might mean if other universes exist with different r
