just having fun here: gravity in basements is lower, because (surface's max gravity falls off in both directions, inward and out) see topic, "where is more gravity, inside or out?". if the basement is deep enough, like reaching down to the center, gravity drops to zero. time to max. If the building is massive enough, gravity will pull up even more, less basement gravity with mass all around. and, better build your tall buildings near the Equator, no speed effects on the poles, just a nice twist., this. thank you, Amber, we are having a great time with this. Found a piece of amber once on the beach with an enclosed insect, it's body having defied increase in entropy for the longest time. I am voting with you, time is fundamental. flight through time without formulae.
