科學好好聽

〈EP.33|如果我們跟光跑得一樣快〉

02 Jun 2025

Description

本節目提到,科學家愛因斯坦提出了光速不變的觀念,認為無論觀察者的運動狀態如何,光速都是恆定不變的。這個觀念源自於他的一個思想實驗:如果他和光跑得一樣快,他將看到什麼?愛因斯坦認為,光是一種電磁波,如果看到靜止的光,就違反了電磁波的規則。因此,他大膽假設光速對任何觀察者都是不變的,這個假設成為相對論的基礎,並引導他推導出許多違反直覺的結論,例如時間膨脹和長度收縮。 Music from #Uppbeat (free for Creators!): https://uppbeat.io/t/augustine/happy-thoughts (https://click.pstmrk.it/3s/uppbeat.io%2Ft%2Faugustine%2Fhappy-thoughts/vZub/Mhq9AQ/AQ/9a81cc98-33e3-4393-988c-e260893fbecf/4/dtHb1EMCam) License code: 8OVD4G7T97U9LV7C Music from #Uppbeat (free for Creators!): https://uppbeat.io/t/augustine/morning-delight (https://click.pstmrk.it/3s/uppbeat.io%2Ft%2Faugustine%2Fmorning-delight/vZub/Xxq9AQ/AQ/ca281cb2-e180-44ce-940b-77e13433f497/4/LsEyUh3NZJ) License code: TWE91SVFFA9Q2WDW -- Hosting provided by SoundOn
