We have this very clean picture of science, you know, these well-established rules with which we make predictions. But when you're really doing science, when you're doing research, you're at the edge of what we know.
From Lisa Randall
I would say it's important for scientists to speak out when they can and when they can be listened to.
There could be more to the universe than the three dimensions we are familiar with. They are hidden from us in some way, perhaps because they're tiny or warped. But even if they're invisible, they could affect what we actually observe in the universe.
We live in a world where there are many risks, and it's high time we start taking seriously which ones we should be worried about.
There is real confusion about what it means to be right and wrong - the difference between what spiritual beliefs are and what science is.
There are a lot of mysteries about quantum mechanics, but they mostly arise in very detailed measurements in controlled settings.
I started out working on supersymmetry. The theory predicts that for every particle we know about, there will be an additional particle.
The standard model of particle physics describes forces and particles very well, but when you throw gravity into the equation, it all falls apart. You have to fudge the figures to make it work.
If you look through the shelves of science books, you'll find row after row of books written by men. This can be terribly off-putting for women.
You can be only a modest distance away from the gravity brane, and gravity will be incredibly weak.
