Biology is usually a lot more fun than physics. It's a lot easier to understand, and there's sex. - Alexander Rosenberg

the answer to the persistent question, What is the purpose of the universe? is quite simply: There is none.

Why is there anything at all? or as the question is famously put, Why is there something rather than nothing? Physics, especially quantum physics, shows that the correct answer to this question is: No reason, no reason at all.

Physics is by no means "finished". But the part of it that explains almost everything in the universe—including us—is finished, and much of it has been finished for a century or more. This includes the physics that we are going to need. Nothing at the unsettled frontiers of physics challenges the parts we're going to make use of. What's more, the physics we need is easy to understand, certainly far easier than quantum mechanics, general relativity, or string theory.
