What is your favorite question you think science will probably never be able to answer?

Some people think that questions like “Which of these flowers is prettier?” cannot be answered by science while other would say “perception of beauty” is a neurobiological feature of human brains.

Some think science can’t answer questions of morality, while others think that human altruism for example is the result of evolution when social groups were faced with selective pressures.

Some might even go as far as saying it’s only a matter of time, because science at least in principal has the potential to explain any (natural) phenomenon.
