She's not the first person to theorize that the universe has hidden dimensions, but she revolutionized the field by suggesting that an extra dimension could be infinitely large and that we might be living in a 3-D sinkhole in a higher-dimensional universe.
Far from posing idle brain teasers, her research might solve one of physics' great mysteries—namely, why gravity is so weak in contrast to electromagnetism and other forces.
After doing some mind-blowing math, she thinks the warped geometry of space-time could mean gravity is weak here and strong elsewhere. But most important, Randall's work suggests ways to test for evidence of higher dimensions. Using
