Interesting.

Case 1
when distance is 0 (0 is you couple together)
-connection is normalized: 0 (0 no love at all between you couple)

time is 1 day, which translates that you need see your significant other everyday, otherwise, she or he may leave for someone else. haha.

Case 2
when distance is 0 (0 is you couple together)
-connection is normalized: 0.9 (0 no love at all between you couple)
time = 1 * sqrt(1- 0)/(1-0.9)^4= 1 /0.0001 = 10000 days
hahaha, 30 years.
