My friend the satellites do not lie, the world map is not a lie just projected to emphasize the water.
Does a satellite operate outside the Earth atmosphere?
No they do not, the highest we can before problems occur is the altitude of ISS and that is where you get the concept of the current you believe to be true.
A single source of info is always a problem.
Don't assume, I merely showed you how round, hollow and flat can occur at the same time.
Ask before you assume.
Now can you disapprove what I have said so far?
