相對論的絕對速度光速中的時間

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

在這裡的時間 所代表的是甚麼

    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.

    愛因斯坦說....如果人類ㄉ速度超過ㄌ光速你就可以追到你之前所反射ㄉ光..

    也就是你可以看到你之前所發生ㄉ事情..就是時光機ㄉ意思

    幫你翻譯一下一樓的 意思大概是這樣

    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...

    當物體以接近光速的速度運動時,如果該物體上裝有計時器,我們會發現它的時間變慢了,這顯示運動速度愈快的話,時間走得愈慢,而壽命得以延長;若速度達到光速,則時間就會「凍結」;當速度超過光速時,時間則往後退,但相對論告訴我們,當速度達到光速99% 以上時,質量會以不可遏阻之勢急劇增加。

    時間是事件(物)一切的發展經過,空間是事件的存在點之無限廷伸之觀念~這是我目前對於「時」「空」的概念。

    相對論所提的超越光速,物質可以脫離時空的限制,脫離所謂的「現在」以及所謂的「老化」....

    不過,"速度的極限是光速"這件事情已經被推翻了,有人發現比光速更快的速度了,不過細節忘了,sorry...^^"
