Common Physics Misconceptions

The video challenges common misconceptions about the Earth's shape, gravity, and relativity. It explains that while the Earth appears flat, it is round, and that gravity affects light due to its energy and momentum. The video also clarifies that velocities do not simply add up as per special relativity, and highlights the cosmic speed limit set by the speed of light. The aim is to correct misunderstandings and provide a deeper understanding of these scientific concepts.

How does the text illustrate the idea that the Earth appears flat, and what is the reality?

Describe the concept of the cosmic speed limit mentioned in the text.
