only 7k post here - there's another 20k posts on Flat Earth in other topics and still no one has proved gravity or understands the difference between the apparent sun and the line of sight Sun. Very sad.
I proved the existence of gravity... here it is again...
the Jugular vein in our necks pump blood more effectively than other veins in order to push blood upwards into our brains, against the pull of gravity...
the fact that our veins achieve their purpose, INCLUDING gravitational pull in the process, proves that gravity is there and that our bodies needed to adapt this characteristic...
every person on the planet can do a quick experiment to show them this effect... its so easy to do... stand on your head upside down and feel the blood rush into your head.... the Jugular vein + gravity = more blood into our heads...
