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


1 Answer 1


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
