I In string/m-theory and 3D/4D Controversy of time

  1. Oct 27, 2017 #1
    how does string theory address 3D/4D Controversy of time

    are strings extended in time in the same way they are extended in space?

    are entities in string theory extended in time and have "time parts"

    is a unstable particle from time t1 to t2 also extended in time, or is it only exist in the present

    does string/m-theory favor A-theory time or B-theory time?

    given that in string/m theory it proposes 9 spatial dimensions and 1 dimension of time, how does string theory view the dimension of time
