最近 看了一些相對論的問題 題中提到速度的極限是光速
時間 會受速度而影響 但是使我對時間的代表產生迷惑

Time is just another dimension in the universe. There are so many different theories and argument on this, but I would recommend you to go to the Caltech library to check out some computer animation video done by Jim Blinn and the professor Goodstein. I think that will enlighten your view on theory of relativity and other physics theories. At least that's how I learned it. It was very beneficial for me, I hope they still have the video available. As you may have known already, Albert Einstein disagreed with quantum physics, he simply thought "God could not possibly create the universe this way!" Many scientists thought he is wrong, but in the recent years, some scientists thought maybe he was right... anyway, so much to talk about, so little time...
Let me update it a little...
When we are talking about physics, we need to put things in the proper frame of reference. Let's say we have a train that can travel at the speed of light. One guy(A) is inside the train, another guy(B) is standing outside the train. A's one second is like eternity for B, but A will still see everything inside the train like he normally would. A would see B growing old and turn to dust in a instant.
As far as for the neutrino travelling at faster than the speed of light, the theory was not to accelerate it to be fast, but it's initial speed is already faster than the speed of light. Since to accelerate any matter to speed of light will take tremedous amount of energy. Every time when you try to double the speed, you will need to quadruple the energy to make it happen. With current human limited knowledge and capability, we just simply can't afford and do not know how to get a person to travel even close to the speed of light.... no propulsion system can possibly come near that speed.

smurf, thanks for the translation. It is quite close to what I was saying.

時間只是其它維度在宇宙。在這有太多不同的理論和論據, 但我會推薦您去Caltech 圖書館看一些由吉姆Blinn 和Goodstein 教授完成的電腦動畫錄影資料。我認為將對您在物理理論學習的意圖會很有幫助。至少我是這樣學會了它。而且對我非常有用喔, 我希望他們那些電腦動畫錄影資料仍然有用。我想你已經想要知道了吧, Albert Einstein 不同意量子物理化, 他簡單地認為"上帝不可能創造這樣的宇宙!" 科學家認為他錯誤, 但在最近歲月, 一些科學家認為他可能正確... 不管怎樣, 想要說的太多太多, 實在也沒什麼時間啦...
