Okay.

So we’ve got an entirely flat surface that also happens to be the exact same length as the earth’s surface.

If you had one continuous piece of string that went from one end of that flat surface to the other, and on one end there was attached a bell… would you be able to ring the bell by pulling on the other end of string?

    Physics. The force you place on that string will effect the far end only at a rate no sooner than the speed of sound thru said medium.

    The speed of sound in metal is about 17000 feet per second. Of materials on earth it has some of the fastest rates of transfer. But if you had a metal rod 17000 feet long and pushed one end a foot, the other end wouldn’t move a foot till a second later. It will compress.

    Interestingly a neutron star has material that is so densely compacted that the speed of sound thru that material is approaching that of the speed of light.
