But even if they're invisible, they could affect what we actually observe in the universe. They are hidden from us in some way, perhaps because they're tiny or warped. There could be more to the universe than the three dimensions we are familiar with. Science is a self-correcting process, too, something that I expect will happen with the recent announcement of neutrinos that may move faster than the speed of light.Ĭan you describe the essence of your idea about extra dimensions? That's part of the point of the book: science proceeds, and we systematically end up with new ideas and explanations, going from the human scales we're very familiar with to scales that are so remote it's hard to have intuition about them. I'm certainly not asking anyone to take on faith any of the ideas that I present. Why should we regard these ideas as more than fanciful constructs? There are a lot of bizarre ideas here, from string theory to a "brane" of extra dimensions right next to our own. We really do have a chance of making inroads on those subjects. Other deep issues include space-time symmetry and whether there are extra dimensions. We have a good chance to see the Higgs particle, which tells us how elementary particles acquire mass. But I also wanted to clarify the nature of science: what it means to be right and wrong, what it means to make measurements, and the roles of uncertainty, risk and creativity.ĭo you feel the physics community is on the verge of finding something remarkable? One goal was to describe the science I'm interested in today: the physics happening at the LHC and searches for dark matter. What were your main goals for your new book? Sensitive detectors now sniff for dark matter, while the most complex scientific machine ever created, the Large Hadron Collider (LHC), beneath the border of Switzerland and France, smashes subatomic particles into one another at almost the speed of light. These ideas, once the sole province of fiction writers, face real tests in a new generation of experiments. She also ponders the makeup of dark matter, unseen particles that have shaped the growth of the entire cosmos. She thinks an extra dimension may exist close to our familiar reality, hidden except for a bizarre sapping of the strength of gravity as we see it. Send us feedback.In her new book, Knocking on Heaven's Door, Harvard University theorist Lisa Randall explores how physics may transform our understanding of the fundamental nature of the world.
