People (the anthroposphere) affect timespace.
EXAMPLE 1 (In Travel):
If you want to go fast, go alone.
If you want to go far, go together.
This is a reminder, not in that large groups are more robust, thus giving them further staying power, but rather, large groups are slow. The more people there are, the slower it is.
EXAMPLE 2 (At a Restaurant):
A party of five takes about 1-2hrs to eat, drink and be merry. A party of ten takes over 2hrs, and a party of thirteen almost 3hrs. The more the merrier (and the longer they take).
Makes one consider civilization and its relationship to the exponential growth of technology, but most importantly, that people exert some type of force on timespace.
