Quotes About Brane

You can be only a modest distance away from the gravity brane, and gravity will be incredibly weak.

He said with utter weariness, That bastard Brane had me where Mamie wore the beads. And he kept pushing me; he was greedy and I was sick of the whole mess I'd got into.

Tegmark cites the work of renowned physicists Paul Steinhardt of Princeton and Neil Turok of Cambridge University, whose calculations indicate the existence of a second three-dimensional brane that is literally parallel to our own plane of existence but separate from us because it is just a tiny fraction higher on the dimensional scale. It's there, and it is part of our current reality, whether we can see it or not.

A brane is a distinct region of spacetime that extends through only a (possibly multidimensional) slice of space. The word "membrane" motivated the choice of the word "brane" because membranes, like branes, are layers that either surround or run through a substance.

Some branes are "slices" inside the space, but others are "slices" that bound space, like slices of bread in a sandwich. Either way, a brane is a domain that has fewer dimensions than the full higher-dimensional space that surrounds or borders it.

Spacetime can be so warped that the gravitational field becomes highly concentrated in a small region near a brane—so concentrated that the huge expanse of an infinite dimension is inconsequential.

In the warped scenario, the field lines are equally distributed in all the directions on the brane. However, off the brane the field lines bend back around so that they become essentially parallel to the brane, almost as if the fifth dimension were finite. Even with an infinite dimension, the gravitational field is localized near the brane, and field lines spread essentially as if there were only four (spacetime) dimensions.
