Скачать или смотреть Where Is the Rest of Gravity? | The Leaking Dimension

Pick up your phone. You just defeated the gravitational pull of an entire planet.

Gravity is 10³⁶ times weaker than electromagnetism. A fridge magnet overpowers Earth. Black holes need to cheat. Something is very wrong.

The hierarchy problem is one of physics' biggest mysteries. Some physicists think they know the answer: gravity isn't weak. It's leaking into dimensions we can't see.

We're not surrounded by another dimension. We're soaking in it.
