從十九世紀以來史學理論的變遷，由“歐洲中心觀”到“在中國發現歷史”，再到當代的全球史觀，人們的視野慢慢擴大。60年代，在美蘇爭霸的背景下，人類開始探索地球以外的空間，逐漸突破了以地球為中心的視覺去思考，取而代之的是從宇宙反觀地球。
《星際穿越》中的科學裡，導演採訪了前NASA宇航員Marsha Ivins，而她回憶起在太空上的經歷，自然的道出了其想法：
"I flew that into space. It's still something that I have a hard time believing. And it makes me feel good that people still have a wonder and an amazement and a pure joy for the fact that we did fly this vehicle into space. I looked up overhead and here was this black sky and this blue Earth. All hits you at that point, I am not on the planet anymore. And every astronaut who has flown has come back and said the same thing. As you circle the Earth you do not see natural borders and boundaries that separate the countries. And all of the wars and the angst and the strife that tear this planet apart seem so insignificant from that view.
這種宇宙視野非常重要。對於人類的意義，它直觀地反映出人類在地球﹑在太陽系﹑更在宇宙是多麼的微不足道。當你參透此一維度，其實，人類過去所創造或發明的什麼，以及個人經歷的那些過不去的坎，都是無關緊要，如在《銀翼殺手》中那句經典話：
All those moments will be lost in time, like tears. in the rain.
所以，我們自己可以活得很平靜﹑坦然，正如宇宙一樣。
