explained extent imply massive number physics possible predict saying string universes
To the extent that we even understand string theory, it may imply a massive number of possible different universes with different laws of physics in each universe, and there may be no way of distinguishing between them or saying why the laws of physics are the way they are. And if I can predict anything, then I haven't explained anything.
belief certain future guide help keeps peaceful reason science ultimately
I don't know if science and reason will ultimately help guide humanity to a better and more peaceful future, but I am certain that this belief is part of what keeps the 'Star Trek' fandom going.
access along channels effect hoped information instead might news open opposite provided rise ubiquitous
The rise of a ubiquitous Internet, along with 24-hour news channels has, in some sense, had the opposite effect from what many might have hoped such free and open access to information would have had. It has instead provided free and open access, without the traditional media filters, to a barrage of disinformation.

Imagining living in a universe without purpose may prepare us to better face reality head on. I cannot see that this is such a bad thing.
case generally imagination people quantum science
Feynman once said, 'Science is imagination in a straitjacket.' It is ironic that in the case of quantum mechanics, the people without the straitjackets are generally the nuts.

The Bible is full of dubious scientific impossibilities, from Jonah living inside a whale, to the sun standing still in the sky for Joshua.
behaves catcher classical experience involves laws mechanics phenomena pitcher quantum quite seems thrown universe
No one intuitively understands quantum mechanics because all of our experience involves a world of classical phenomena where, for example, a baseball thrown from pitcher to catcher seems to take just one path, the one described by Newton's laws of motion. Yet at a microscopic level, the universe behaves quite differently.
planets our-future species
If our species is to survive, our future will probably require outposts beyond our own planet.
ethos keys common-sense
Science has been effective at furthering our understanding of nature because the scientific ethos is based on three key principles: (1) follow the evidence wherever it leads; (2) if one has a theory, one needs to be willing to try to prove it wrong as much as one tries to prove that it is right; (3) the ultimate arbiter of truth is experiment, not the comfort one derives from one's a priori beliefs, nor the beauty or elegance one ascribes to one's theoretical models.

If you have nothing in quantum mechanics, you will always have something.

We need to walk into the future, no matter how unnerving, with open eyes if society is to keep pace with technology.
