 Additionally, Elitzur and Dolev believe that certain quantum mechanical experiments provide evidence of apparently inconsistent histories, and that spacetime itself may therefore be subject to change affecting entire histories.Amrit Sorli and Davide Fiscaletti, founders of the Space Life Institute in Slovenia, argue that time exists independently of space, and that time dilation and length contraction can be better described within the framework of a 3D space, with time as the quantity used to measure change.Sorli and Fiscaletti argue that Minkowski spacetime, and the understanding of time as the fourth dimension, lacks any experimental support.
