  1. We've seen time dilation. We've seen clocks slow down and speed up. GPS satellites take into account time dilation. Oh, and, by the way, earth isn't flat.

  2.  @axeman2638  Sorry but it does. GPS satellites have well-documented adjustments for relativity. There's more; we see muons from high altitude cosmic rays events that can only reach the ground before decaying due to time dilation. We can see red-shift in radiation climbing out of earth's gravity well. An atomic clock was put aboard a jet and compared to one that was left on the ground, and the time difference was what was expected. Relativity confirmed.

  3.  @ephesians6ten185  The bandwagon fallacy is deference to the opinion of the majority. I didn't do that. Try again. :)

  5.  @ephesians6ten185  Gravity works fine without buoyancy, but gravity is what gives direction to buoyancy. Mass has been repeatedly shown to attract mass, and it's not just droppity. If density and buoyancy was all that mattered then a pound of feathers would weigh as much as a ton of feathers. Earth isn't flat. Thank you for playing.
