I have been looking at and researching Einstein's theory space and time more and cannot find an explanation for where time fits into his fabric of spacetime. I can see how space fits into it via gravity and such, but how is time represented in this?

Fabric of spacetime

Another reason that the 2D picture is confusing, is that it shows a 3D solid distorting a 2D surface. In reality, familiar 3D objects are actually 4D (3 of space and 1 of time) and their mass distorts a 4D fabric woven from space and time.

    $\begingroup$ @gamerPlayz Probably try to read and understand the math and real physics of relativity, why you need time as a relative object like space to be able to deal with the constancy of the speed of light. If you understand special relativity you'll understand why we need 4 dimensions, and your study of general relativity will make more conceptual sense. $\endgroup$

  • $\begingroup$ All analogies are flawed, but the rubber sheet one at least captures two important facts: matter curves space time, and the curves of space time dictate the paths of matter. $\endgroup$ Jan 29, 2017 at 7:34
