What's Actually Inside Empty Space - Leonard Susskind

Описание: Point to an empty spot in the room you're sitting in right now. That space you just pointed to — it's not empty. It never was. And physics can prove it.
What you call "nothing" is one of the most violent, most active regions in the entire universe. It's seething with energy. It's crackling with fields. It's constantly creating and destroying particles too fast for any instrument to catch. And it has been doing this since before the universe was a second old.
Empty space doesn't exist. It never did.
In this video, Leonard Susskind explains what's actually inside the vacuum — and why the answer is the biggest unsolved problem in all of modern physics. Why the uncertainty principle makes true emptiness mathematically impossible. Why two metal plates in a perfect vacuum are pushed together by the force of nothing. Why 68% of the entire universe is made of the energy of empty space. And why the gap between what quantum theory predicts about the vacuum and what we actually measure is the largest discrepancy in the history of science.
The nothing is doing something.
Right now. In the spot you just pointed to.
What you'll discover:
→ Why the uncertainty principle makes empty space physically impossible
→ What the Casimir effect is — and why it proves the vacuum has energy
→ Why every cubic centimeter of "empty" space is full of quantum fields
→ What dark energy actually is — and why it lives in the vacuum
→ Why the cosmological constant problem is the biggest crisis in physics
→ Why you are not mostly empty space — you are mostly field
