Main Question or Discussion Point
If space time (the universe) is infinitely expanding what happens when it rips? Have we observed Virtual particles in an area and counted them? Does the expansion of space time affect the amount of Virtual particles in a particular area? Is it theoretically possible to expand space time to a point that it would rip? Is it possible that the higgs field expands with space time? Could the gravity from 1 single virtual particle be enough to cause a rip in a enormously empty space time void from infinite (maybe not) expansion?
