The Galaxy That Makes Us Question Gravity Itself

Описание: What happens when a galaxy spins so fast it should tear itself apart?
UGC 12591 rotates at nearly 220 miles per second—more than twice the speed of our Milky Way. By all known laws of physics, its outer stars should have been flung into the void billions of years ago. Yet it holds together perfectly. Something is very wrong with our understanding of gravity.

This documentary explores one of the most important questions in modern physics: Is the universe filled with invisible dark matter we cannot detect? Or is our theory of gravity itself fundamentally incomplete?
In this video, we cover:

Why galaxies don't rotate the way Newton's laws predict
Vera Rubin's discovery of flat rotation curves
Fritz Zwicky's dark matter hypothesis and why his colleagues ignored him
What dark matter is supposed to be and why we can't find it
The WIMP hypothesis and decades of failed detection experiments
Mordehai Milgrom's MOND—a radical alternative that modifies gravity itself
The Bullet Cluster and why it challenges modified gravity theories
What the James Webb Space Telescope is revealing about early galaxies
How UGC 12591 tests both theories to their limits
The future of gravitational research: LISA, Euclid, and beyond

Whether dark matter exists or gravity works differently than we thought, the answer will reshape our understanding of the universe.
