把这一句，留给此刻的你

If we do discover a complete theory, it should be in time understandable in broad principle by everyone. Then we shall all, philosophers, scientists, and just ordinary people be able to take part in the discussion of why we and the universe exist.

如果我们确实发现了一个完整的理论，它应该在时间上被大家普遍理解。然后我们所有人，哲学家，科学家，和普通人都能参与到讨论为什么我们和宇宙存在。
