minus-square@mmcmonster@lemmy.worldlinkfedilink3•1 year agoHow about something simple: Why does gravity feel the same as acceleration?
minus-square@applebusch@lemmy.worldlinkfedilink10•1 year agoYou can’t feel gravity. What we feel really is acceleration, the acceleration of the earth pushing us up against gravity.

Standing on a surface in a gravity well means you’re being constantly pushed out of an inertial frame, by not allowing you to follow a geodesic path in spacetime, and the same effect happens under acceleration. https://youtu.be/XRr1kaXKBsU
