Does Spacetime Have Any Time Dimension?
FollowThe concept of time as a way to measure the duration of events is basically intuitive. Some researchers believe that this Newtonian idea of time as an absolute quantity and fourth dimension in spacetime is incorrect. They propose to replace these concepts of time with a completely new view: time as a measure of the numerical order of change.
Einstein never interpreted time as a fourth dimension of space. By this theory, space is not 3D + T, space is 4D. With clocks we measure numerical order of material change. This numerical order is the only time that exists in a physical world. 4D space is a medium of quantum information transfers.
Scientists at the Scientific Research Centre Bistra in Ptuj, Slovenia, theorize that this Newtonian idea of time as an absolute quantity, along with the idea that time is the fourth dimension of spacetime, are not accurate. They propose to replace these concepts of time with a view that say that time is a measure of the numerical order of change.
This view doesn’t mean that time does not exist, but that time has more to do with space than with the idea of an absolute time. So while 4D spacetime is considered to consist of three dimensions of space and one dimension of time, this view suggests that it’s more correct to imagine spacetime as four dimensions of space. In other words, the Universe is “timeless.
