The link describes chaos as having "infinite amounts of time and space dimensions" while the cosmos "only has three spatial dimensions and one linear time dimension"
This material is remarkably poor. Even a casual reading of "20 and back" literature would provide a variety of apparently experiential accounts of time travel and interdimensional travel.
"One of the alleged hallmarks of the 20 and back program is that it involves highly advanced technology (
