# 狹義相對論

## 概論

1. 所有慣性參考系入面嘅物理法則都係一樣嘅；而且
2. 無論一個觀察者同個光源點郁，所有觀察者見到嘅嘅速度都係一樣嘅。

• 時間膨脹：兩個一樣嘅時鐘，兩者之間嘅相對速度唔等如零，佢哋量度到嘅時間會唔一樣；
• 長度收縮：一個觀察者量度一件同佢相對速度非零嘅物件嘅長度，佢度到嘅長度會同細過件物件嘅真實長度；
• 相對質量：一個觀察者量度一件同佢相對速度非零嘅物件嘅質量，佢度到嘅質量會同大過件物件嘅真實質量；
• 質能等價物質能量本質上係同一樣嘢，${\displaystyle \mathbf {E=mc^{2}} }$
• 宇宙速度極限：宇宙入面，物件最大嘅可能速度係光速

... 等等。要留意嘅係，上述呢啲現象要喺物件速度接近光速嗰陣先會睇到[6][7]
