Conscious Energy Posted March 14, 2021 Share Posted March 14, 2021 Hello Community! One moment follows the other in every point of the volume space is. There is no point of space where time could flaw backwards. Can I say that time is Linear since in every point of space it is pointing to the Future?

Bufofrog Posted March 14, 2021 Share Posted March 14, 2021 Since 2 observers in different inertial frames won't agree on the rate that time passes, I don't think time can be called linear. I think sequential is a better term since observers will agree in the order that related events occur 1 Link to comment Share on other sites More sharing options...

I liked both the answers given so far, +1 to dimreeper and bufofrog. Just to add that perhaps linear is the wrong word for what I think mean. I think you mean homogeneous, which is the posh scientifc way of saying that every second of time is the same as every other second. Scientifically linear means something other than lined up or in a line. It refers to some very specific mathematical properties. So specific that even most straight line graphs are not linear!

MigL Posted March 14, 2021 Share Posted March 14, 2021 What 'time' are you referring to ? Proper time is necessarily linear, as the clock moves along your wordline. "In relativity, proper time along a timelike world line is defined as the time as measured by a clock following that line. It is thus independent of coordinates, and is a Lorentz scalar.[1] The proper time interval between two events on a world line is the change in proper time." Co-ordinate time is not necessarily linear. "Coordinate time is the time between two events as measured by an observer using that observer's own method of assigning a time to an event. In the special case of an inertial observer in special relativity, the time is measured using the observer's clock and the observer's definition of simultaneity."

A point in space implies that it is a 3rd inertial frame. So I would say both the observers would see there own clock ticking at a normal rate and they would both agree that a clock in the 3rd frame ticked slower. However, the observers would not agree on how much more slowly the 3rd clock was ticking. Link to comment Share on other sites More sharing options...
