Try to imagine nothing. Absolute nothing.
You can't. And after watching this video, you'll understand why.
What's between the atoms that make up everything - your body, this room, the entire universe? Most people say empty space. Void. Nothing.
They're completely wrong.
In this video, we explore what really fills the space between atoms, why you've never actually touched anything in your life, and how the quantum vacuum is the busiest place in the universe.
What you'll discover:
→ Why the space between atoms is not empty
→ Electric fields: the invisible fabric holding reality together
→ Why you're floating right now (and always have been)
→ Virtual particles: matter appearing and vanishing billions of times per second
→ The Casimir effect: proof that empty space pushes things around
→ Why the universe is incapable of true emptiness
Nothing doesn't exist. Never did. And once you see it, you can't unsee it.

This video was inspired by Feynman's original work. If you want to read it yourself:

📚 "Six Easy Pieces" — Chapter 1 (Atoms in motion)
📚 "The Feynman Lectures on Physics — Volume 1" — Chapters 1-2 (Atoms, matter, basic physics)
📚 "The Character of Physical Law" — Chapter 1 (The law of gravitation as an example)

Prema najboljoj fizikalnoj teoriji  svemir nije izgrađen od čestica već kvantnih polja - nešto poput fluida. David Tong objašnjava što znamo o ovim poljima i kako se oni uklapaju u naše razumijevanje svemira.

Davi Tonge je profesor teorijkse fizike na Cambridge, specijaliziran za kvantnu teoriju polja.
