“Seth material” search engine (Jane Roberts)

Physically, you do not exist for as long as, or the same amount of your time, that you do exist. We have called the interval of physical nonexistence antimatter, or negative matter. This of course from your viewpoint.

This antimatter therefore, by inference, exists in duration on your terms for as long as your own universe of positive matter has existed. It might seem to you that the universe of antimatter is a twin of your own. On physical terms it is indeed, although it is in a divided state. By this I mean that I herein include two universes very closely connected with your own.

However, the personalities that inhabit these seemingly twin bodies to your own are not the same. Your scientists have already discovered the theory of antimatter, but assume that it is completely separate from your own universe, I believe the latest theory being that a universe of antimatter may possibly be found at the furthest reaches of your known universe.

Antimatter exists simultaneously with your own universe, and approximates it in terms of your own idea of time. This may be possibly discovered within a short time, but it will not be accepted. Because of the perilous and necessary relationship and balance between matter and antimatter, it will never be possible for you to contact the universe of antimatter.

Perhaps then your universe of positive matter, and the two surrounding universes that compose so-called antimatter can best be described as two ends of a spectrum that by nature can never meet.
