[#1] The Beauty of General Relativity    

I want to share with the people who like science and physics the most intuitive and easy-to-understand short film I have ever seen about general relativity.


Thank you.

I would also like to share with you guys the beauty of quantum mechanics:

I spent tremendous effort in persuading my wife to see this documentary. And I succeeded.

General Relatively explains how space-time is distorted by mass (gravity), by does not explain why.

It takes a united field theory to unify General Relativity and Quantum Field Theory, which might also explain the question "Why?".

The life-long search by Einstein of a united field theory was continued by scientists like Stephen Hawking who, regrettably, died without a success.

I took a genius to think acceleration and gravity are the same thing in nature, and even crazy to think time is not absolute.

其實啲 field theories 講到天花龍鳳,甚至乎有小數嘅維度,真實嘅世界係點?你解個方程解出一大餅超級無敵複雜嘅嘢,study 吓佢,對得多就唔再陌生,進而賦予佢所謂嘅「物理意義」,其實有乜意義?

正如你用開牛頓力學,覺得「力」好實在,好有物理意義,但係如果呢個世界係用 Lagrangian mechanics,咁你就會覺得「力」呢樣野好抽象好奇幻。

Entities are much more elastic than we humans could ever possibly fathom.

Simple daily things like simultaneity is never absolute and is dependent on the observer.

Answers to simple questions like "Why" heavily rely on an agreed framework and to an agreed degree of satisfaction. Otherwise such "why" questions will be repeated infinitely.

Human's agreed truth, to a human being, is never more relevant than ant's agreed truth to an ant.

I think this video is cool because it provides a simple and vivid explanation of why the shortest path bends in the gravity field and why observers without gravity will see the clock in the gravity field run slower.
