愛因斯坦 的< E=mc2 > 是否就是狹意義相對論

E=能量
m=質量
c=光速

愛因斯坦既相對論提過..當物體高速運動達到光速以上便會發生神奇的事。
亦即是人們所稱的穿越時空..不過只是理論..目前還未有人證實過。

不過外國已經有國家進行緊「粒子碰撞實驗」..即是兩粒粒子高速運動，
達到光速後再兩者相撞，模擬太陽的形成..亦即時核聚變，
不過霍金曾經用100元美金輸賭,這個實驗不會成功..
況且，如果真的能成功..黑洞可是巨大質量的東西，吸力也相當大(地球地心吸力)
有網上預言家 john titor 提過，他是使用小黑洞來穿越時空，
但後來從他一個預中被推翻，就是(2008年北京奧運不能舉辦)
舉個例:你有時光機，你回到過去把自己殺掉，那麼你自己會怎樣?
粒子是不會增加或減少..

所以相對論也只在證實狀態。

Albert Einstein published his "special theory of relativity" in 1905. Later in the (same) year, he published another paper, using the basis of special relativity theory, arriving at an equation for "mass energy equivalence". Therefore, the equation E=mc^2 was in fact publsihed separately from the theory of relativity, although the two are publish in the same year.

The following paragraph is quoted from the web-page given below:

"That same year, which has been called Einstein's annus mirabilis or "miracle year", he published four ground breaking papers, on the photoelectric effect, Brownian motion, special relativity, and the equivalence of matter and energy, which were to bring him to the notice of the academic world.
