Dark Matter: The Invisible Thing Holding the Universe Together

Описание: Tonight we explore one of the most profound mysteries in modern physics: dark matter. The invisible substance that makes up 85% of all matter in the universe, yet we've never directly detected it.
From Fritz Zwicky's controversial observations in the 1930s to Vera Rubin's definitive rotation curve measurements in the 1970s, this video takes you through the compelling evidence that most of the universe is made of something we cannot see, touch, or detect directly—something that only reveals itself through gravity.
We'll examine:
How scientists discovered galaxies spin too fast to be held together by visible matter alone
The gravitational lensing observations that map invisible mass
Evidence from the cosmic microwave background proving dark matter existed in the early universe
Computer simulations showing the universe only makes sense with dark matter
Leading candidates for what dark matter might be: WIMPs, axions, sterile neutrinos, and primordial black holes
The ongoing search in underground detectors and particle accelerators
Why dark matter means you're constantly surrounded by billions of invisible particles passing through you every second
This isn't just about an astrophysics problem. It's about the fundamental nature of reality—the humbling fact that 95% of the universe (dark matter plus dark energy) is invisible to us, yet shapes everything we can see.
By the end, you'll understand why the universe you think you know is just 5% of what actually exists, and why the invisible scaffolding of dark matter is what makes galaxies, stars, planets, and life itself possible.
The universe is held together by something we cannot see. That's both humbling and wonderful.
