strange mental delusion that one
next you'll be saying you swan the nile and it was never uphill
crocodiles knew you were testing out your theory and agreed not to eat you
Water doesn't always flow downhill
it always obeys the laws of science and gravity
if something of an extraordinary mass like a collapsed star came near the earth then the gravitational pull of the black hole type mass would suck all the water up into the atmosphere at same time it would pull the earth into its field and suck it into the invisible mass that already exists in the black hole.
So theoretically, at least water does NOT always run downhill
But the applied mechanics of physics has proved beyond any doubt that gravity is related to mass of the biggest mass affecting its molecules which in this case
is the giant globe called earth
the water molecules are attracted to the globe just like humans and will try find the centre of gravity with biggest mass, which again is the globe
It so easy they teach it to twelve year olds and if you get a book about newtons laws (notice NOT theory) and understand it if your brain is functional.
Are you claiming your so low in iq that its beyond your capacity?
