Einstein's Proof of E=mc2

The video explores the principle of relativity, using a cat and Einstein to illustrate how motion is relative. It highlights the problem of light's constant speed, which cannot be altered by changing frames of reference. The solution involves rotating time slices, allowing for the explanation of motion while maintaining light's speed. Lorentz initially discovered this concept, but Einstein recognized its physical reality, proposing that time is relative and simultaneous events differ between observers.

Explain the significance of the speed of light in the context of the switcheroo mentioned in the text.

What does the text imply about the relationship between simultaneous events for different observers?
