For the past few years , after flipping through and careful reading of astronomical and scientific journals and websites , my thought on dark energy is just like what richard feynman tried to explain to his colleagues in caltech why boson had integer spins and fermion had half - integer spins 經過這幾年翻閱及細讀天文及科學期刊及有關網頁,筆者對暗黑能量的感想,就如同費曼對他在加州理工的同事嘗試解釋為何玻色子自旋為整數的粒子而費米子自旋為半整數的粒子時一樣。
