...many intriguing implications of this model is an explanation for why gravity is so weak compared to the other fundamental forces. According to Randall, the strange geometry of these higher dimensions could mean that gravity varies between the dimensions, and happens to be weak in our three dimensional brane...
...Randall claims that these dimensions could be infinitely large provided that space has a warped geometry. In effect, we could be living in a three-dimensional pocket of higher dimensional space. Randall refers to these pockets in space as branes. Like a bead on a wire that can only move along one dimension, a brane may restrict our motion to three dimensions although other dimensions exist...
...force’s strength becomes exponentially weaker further from the gravity brane...
...Gravity is so strongly peaked near the brane that gravity doesn’t leak away,” Randall says. “If you are anywhere except the brane where gravity is concentrated, you would see gravity as very weak...
...whole new dimension to physics—figuratively and literally. This informal textbook argues that the universe has more than the traditionally recognized four dimensions. Randall proposes that our physical reality is simply a slice of space, a “membrane” or “brane,” in a higher-dimensional bulk. She argues that the root “fabric” of the universe has five dimensions. This is hardly a pedestrian concept to the average reader, but Randall makes these abstractions accessible by inserting fictional passages and popular song lyrics...
