黑洞

很多人問過我,為什麼讀物理、讀天文。又為什麼要寫文章。

我不懂回答。我只是對這些東西很著迷。偶爾想分享。

每個人都對每件事物的感受都不相同。我看不到方法,可以令一個人完全明白另外一個人的感受。看似冰冷的宇宙,其實是投射感情的好方法。

宇宙非常大。在遙遠的時空中,幾十億光年外的黑洞周圍發生了一些事情,在我細小的腦袋中竟然能夠了解一點點。很神奇。而宇宙既然這麼大,人類其實非常渺小。可是,仍然有比人類小得多的事物。原子裡面發生什麼事情?也很神奇。時空很大,量子定律又非常小。夾在中間的人類,每天為不同的原因煩惱著。

我不認為科學是最重要的。在科學以外,我是一個感情用事的人。

水星和火星不會相戀,電子和夸克不會煩惱。在不完美的生活中,走進黑洞裡,是一種放鬆。我們這些不完美的靈魂,偶爾把情感投射到無盡的時空,也許就能夠得到一點安慰,也許這就是宇宙令人類著迷的原因。

或許我只是很愛宇宙裡面的那個她。
