Strings in the Bulk · open, closed, and stretched between branes

STRINGS IN THE BULK — open ends on branes, closed loops in the volume

simulation time: 0s

open strings: 0 stretched: 0 closed (bulk): 0 closed (on brane): 0

drag — orbit · wheel — zoom · click a brane — spawn open string · shift-click bulk — spawn closed

R reset · space pause · A auto-orbit · S trigger string event · P pluck a string

STRING TAXONOMY

OPEN — endpoints stuck to a brane (matter)

STRETCHED — endpoints on different branes (gauge boson)

CLOSED · brane — loop bound to a brane

CLOSED · bulk — graviton, free in the bulk

"in string theory, every particle is a tiny vibrating string. open strings — with endpoints on branes — give the matter and forces of the standard model. closed strings travel the bulk and carry gravity." — M-theory primer
