I am just a child who has never grown up. I still keep asking these ‘how’ and ‘why’ questions. Occasionally, I find an answer. - Stephen Hawking

why are we here?
where do we come from?
traditionally,these are questions
for philosophy,but philosophy is dead

Quantum physics might seem to undermine the idea that nature is governed by laws, but that is not the case. Instead it leads us to accept a new form of determinism: given the state of a system at some time, the laws of nature determine the probabilities of various futures and pasts rather than determining the future and past with certainty.

the most important point: that the universe is governed by a set of rational laws that we can discover and understand.
