If time is noted as (x, y)

where x is a number that starts from 0 and counts by ones

and y is a large matrix describing an event unique to that time x.

then could there ever be an instance when two values of x have the same value of y?

for example:

x1 = time 4242521

y1 = [earth was formed]

x2 = time 4242522

y2 = [gasses in earth moved a bit]

so basically can time 4242521 and 4242522 ever contain the exact same event?
