Gravity and the Equivalence Principle | Breakthrough Junior Challenge 2022 |

#breakthroughjuniorchallenge
This is my entry for the Breakthrough Junior challenge 2022.
It is about General relativity and how it modifies our description of gravity. In the video we talk about the Equivalence Principle and the curvature of spacetime. And how all of it fits together.

Thanks for watching.

This is really simplified but can give an idea of ​​what it is all about. For example, if you were to jump into a spaceship, you would not feel any difference only if the mass of the spaceship is the same as that of the Earth. The law of conservation of momentum.

What is the mass of photon ? . If your ans is zero then , a photon can be spilt into electron and positron which both have mass , so does a photon is violating conservation of mass ?🧐

[@priyanshnamdeo]

mass can be directly converted into energy (this is how nuclear bombs work , E = mc^2). So conservation of mass isn't really a fundamental law. Conservation of energy is more accurate. But it can also be violated in specific instances.
