earth carrying the rest?

Both earth and the rest represent matter...that's your mind on thermodynamics establishing friction between shapes of matter.

Before matter implies motion, hence before (being forwarded)...it's motion which carries earth and the rest forwards, and it's your mind which ignores the foundation of being (life) carried forwards (inception towards death).

like the center of a disc

a) Only at the center of motion can there be a shape aka matter.

b) Motion implies same, within which matter can be shaped differently or alike one another.

c) Disc/disk/dikein - "to throw"... https://www.etymonline.com/word/disk

Nature throws (inception towards death) being (life), hence from a flat line into living shape, while giving the opportunity to reshape.

anti arctic are the edges?

Not the edges of matter, but motion moving through matter aka knowl-EDGE...hence being (life) carried in-between opposites (inception/death) aka anti-arktos.
