Also, tangled knots happen in space. What kind of space can time get tangled within?
Now that's another fun question! It also makes me wonder, how would space behave in tangly time?
Would the space in which time gets tangled be primarily around extreme phenomena like black holes, or the very beginnings of the universe (or a universe, if one wants to get into multiverse angles)?
