More about relativety 4

It is a revolution from Newton to Einstein.

However, not everyone liked this revolution. A lot of people want to prove Einstein wrong.

A few of them did this because they believed in Newton very much. Some others did this because they doubt speed of light would be the limit of the speed.

Unfortunately, about a century later, there was still no one succeeded. A few of them are very smart, but their effort was futile at last.

So first thing first, never start the journey to challenge Einstein unless one has no life.

Tell you the truth, I am also the one who doubt that speed of light would be the limit of the speed. Someone then maybe asked me, why should we believe in Einstein? What if Einstein was wrong?

Here comes my answer.
It is easy to say someone else are wrong. But more important thing is to bring forth the reasons and the facts if you want to challenge an authority.

Unfortunately, anyone's intuition could be wrong sometimes. You need to put sense into the community when you have some new ideas. Sometimes you need to work really hard to do it.

Until now, Einstein was still the one with the best insight of the relativity. That says a lot. It is almost impossible to challenge an authority if one doesn't have a better insight than him.

So before we want to speak of the theory of the relativity, let's talk more about speed of light.
