You cannot change the laws of physics ... but could physics actually enable us to travel through time? It might sound crazy, but according to Einstein's theories, there's no logical reason why time travel isn't possible and there are now scientists looking into it as a serious scientific proposal, at least at a theoretical level.
    你無(wú)法改變物理學(xué)定律……但是物理學(xué)能否使我們?cè)跁r(shí)間中旅行呢？這聽(tīng)上去或許像個(gè)癡想。但是根據(jù)愛(ài)因斯坦的理論，時(shí)間旅行在邏輯上不是不可能的?，F(xiàn)在科學(xué)家正把它視為一個(gè)嚴(yán)肅的科學(xué)命題，至少在理論上如此。
