# 先決程式

「思考作業系統」這個概念，是不是幫你解決了一些心結？

（安：不只是「解決了心結」那麼簡單，而且它賦予了我，一個嶄新的角度。）

# Graviton 3

An interesting feature of gravitons in string theory is that, as closed strings without endpoints, they would not be bound to branes and could move freely between them. If we live on a brane (as hypothesized by some theorists) this “leakage” of gravitons from the brane into higher-dimensional space could explain why gravitation is such a weak force, and gravitons from other branes adjacent to our own could provide a potential explanation for dark matter.
