Like The Big Bounce but instead of, "bouncing", after an Eon, Space passes through itself due to 4-D Inertia and inverts into Anti Space then back into Space after another Eon, Cycling in the same sense as Wavelength of Light does, complete with a Peak and a Trough, with both of those being the moment just before Space or Anti Space, (Respectably), begins collapsing due to Gravity.
