# 時光機

「你乘時光機回去『過去』，改變『過去』」會導致「你就不會乘時光機回去『過去』，改變『過去』」。那就構成邏輯矛盾。「改變過去」不單只是違反科學，更重要的是，它違反邏輯。

# Clarke’s three laws 2

.

For many years, Robert A. Heinlein, Isaac Asimov, and Arthur C. Clarke were known as the “Big Three” of science fiction.

During interviews, both in 1993 and 2004–2005, he stated that he did not believe in reincarnation, citing that there was no mechanism to make it possible, though he stated “I’m always paraphrasing J. B. S. Haldane: ‘The universe is not only stranger than we imagine, it’s stranger than we can imagine.‘”
