何謂超時空???

零度空間是點,一度空間是長度,二度空間是面積,三度空間是體積,四度空間是時間.如兩點要在一起,第一是長要相同,第二是濶要相同,第三是高要相同,第四是時間要相同,它們才會重疊.
超時空即回到過去或去到未來.不過這樣是很難做到的.

Meaning: "beyond the dimensons of time and space".

Typically we consider:
1. the physical space as 3-dimensons (lenght x width x height) and
2. the "time" as 4th dimenson;

If something is beyond these 4 dimensons you call that 超時空. A typical example is the "magic goodies" in Doramon's pocket:)
