At galactic scales, matter
within branes will have a range of distributions of orbits and velocities about a given barycentre.
Space
within the branes expands, and at first the distance between the branes (in the bulk) grows too.
Calculations suggested that the crash would generate a universe - wide fireball of pure energy
within each brane.
Most of the particles in our universe stick
within the brane, but theorists have proposed that some neutrinos might be able to travel through the bulk as well.
Not exact matches
Just as two sheets of paper could be blown together in a storm, different 3 - D
branes could collide
within the bulk.
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.
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.
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.»
