Where there's a query, there's a forum! I'm glad I found this place. So here's my quandary. The earth is rotating. It's orbiting the sun. Our solar system drifts through the galaxy which galaxy is drifting through the universe. Supposedly, even though I stand still, I'm moving in some strange, undefined, curved/wobbly path through the universe. Is it all relative? When a plane flies in it's curved path around the earth, does the rotation of the earth or it's orbit influence the path of the plane? Does the gravity bubble we live in some how zero out the rest of the universe so when we do tests involving kinetic energy and things moving, it's all relative to us so that no matter if we're hurdling through the dark, something is either moving or not moving relative to us? Can we somehow detect the layers of force that work on us or are we so far down at the bottom of the totem pole of it all that any force that moves our world any beyond is irrelevant? Is there another question I have not asked that I should be asking that can be answered? I'd like to know what that is too. Where does gravity play in all this? If the earth is rotating, don't I have some kinetic energy in play, but because of the fact that any instrument to test that is moving too, that it zeros out the rotation of earth, orbit, system and galaxy drift? You'd think I could just go play StarCraft or watch a movie, but no, the secrets of the universe demand to be answered! And I had to come here to find some understanding of it all. Thank you for anyone who can break apart this kinetic onion.
