好書導讀 | EP012 《宇宙的構造》為什麼此刻對每個人都不一樣｜布萊恩格林 宇宙的構造 深度導讀

我們每天說現在幾點，現在心情如何，卻從來沒有懷疑過，此刻本身可能根本不是一個所有人共享的真相。這一集，Jenny和你聊物理學家布萊恩格林的宇宙的構造。從一個關於仙女座星系的思想實驗開始，帶你看見，此刻其實是你的位置和速度算出來的一條線，而不是一條真的在流動的河。時間為什麼感覺在往前走，答案跟熵有關，跟你的記憶有關，跟你以為理所當然的一切都有關。這集也有Jenny不完全認同的地方，物理學可以說時間是幻覺，但活著的重量，不是幻覺。 Every day we say things like what time is it right now, but we never stop to question whether now is actually a fact shared by everyone. In this episode, Jenny explores The Fabric of the Cosmos by physicist Brian Greene. Starting with a strange thought experiment involving the Andromeda galaxy, she walks through why the present moment might not be a river flowing forward, but a line drawn by your own position and speed. Why does time feel like it is moving at all? The answer has to do with entropy, memory, and everything we have always taken for granted. This episode also includes the part Jenny cannot fully agree with. Physics may call time an illusion, but the weight of being alive inside it is not. Powered by Firstory Hosting
