The big bang possibly came from two higher
dimensional branes that bumped each other.
Particles could be stuck to a three -
dimensional brane, sort of like things could be stuck to the two - dimensional surface of a shower curtain in our three - dimensional space.
Not exact matches
In keeping with this two -
dimensional analogy, string theorists describe our observable universe as a membrane — «
brane» for short — flapping in the breezes of the actual 10 -
dimensional cosmos.
Some versions of string theory, an all - encompassing theory of particle physics, suggest that our three -
dimensional universe could exist within a four -
dimensional sheet called a
brane.
This
brane may, in turn, occupy a higher -
dimensional space known as the bulk.
What I'm studying is
branes, membranelike objects in higher -
dimensional space.
So when the authors claim that our 3 - D universe is part of a 10 -
dimensional «
brane» and that cycles of expansion and contraction result from collisions between our cosmic
brane and a neighboring one, the best most readers can do is visualize two giant hands clapping the universe into existence over and over again.
In this new view, time didn't have a beginning, and the Big Bang resulted from a collision of
branes, sheetlike spaces that exist within a higher -
dimensional reality.
M - theory postulates multiple parallel universes («
branes») existing alongside ours in some higher
dimensional space (the «bulk»).
In the process, it shed another kind of
brane into the 11 -
dimensional gap.
They collapsed one of these dimensions mathematically into a minuscule line, yielding an 11 -
dimensional spacetime, flanked on either side by two 10 -
dimensional membranes, or
branes, colorfully dubbed «end of the world»
branes.
Some physicists have proposed that nearly all the particles in our universe may be confined to a four -
dimensional «
brane» embedded within a 10 -
dimensional «bulk.»
