not bad
not bad but we don't reely know what the 4th dimenshion is we think it is time. "Time is but an illusion" some1 sed and i beleave them because how can sunthing that changes so often be a measherment of anythang. if you were to leve earth a day wold be near anywere from 12 to 54 hours earth time it can be even shorter or longer pending on point in the unaverse. "after leveing earth ageing slows... basicly time travel" if u reely think about it u were just time traveling and still are.
ok in short time may or may not be the 4th dimenshion and time travel das already ocurd and is still hapening
