Travel at faster than the speed of light certainly can have dramatic implications that are difficult to understand, such as time travel.
Lisa RandallAlthough I was first drawn to math and science by the certainty they promised, today I find the unanswered questions and the unexpected connections at least as attractive.
Lisa RandallSpeculation and the exploration of ideas beyond what we know with certainty are what lead to progress.
Lisa RandallI had this illusion that if I kind of dressed badly that I wouldn't stand out. You know, so I actually went out of my way to not look different to the extent I could.
Lisa RandallThere are many aspects of time we just do not understand. Thatโs the thing about writing a popular book: You realize the things you understand because for those you can give a really simple explanation. But some things about time I just donโt know how to give simple explanations for, even though I can tell you mathematically whatโs going on.
Lisa RandallPhysics has entered a remarkable era. Ideas that were once the realm of science fiction are now entering our theoretical ย and maybe even experimental ย grasp. Brand-new theoretical discoveries about extra dimensions have irreversibly changed how particle physicists, astrophysicists, and cosmologists now think about the world. The sheer number and pace of discoveries tells us that we've most likely only scratched the surface of the wondrous possibilities that lie in store. Ideas have taken on a life of their own.
