[–] ThatWeirdGuy1001@lemmy.world [S] 18 points 3 weeks ago* (1 child) I brought this up on another comment that's for some reason now deleted but, if the universe moves around you, would you not perceive it as movement? permalink fedilink source parent hideshow 2 child comments replies: [–] Derpenheim@lemmy.zip 6 points 3 weeks ago (1 child) There is no such thing as an absolute inertial frame of reference. If you are in free fall on earth, you would experience the same sensation as being in space. The only things that would tell you otherwise are the air resistance hitting you and what you can see. So no, you would not be able to tell the universe is moving around you unless something else in the universe hit you. permalink fedilink source parent hideshow 2 child comments replies: [–] tomi000@lemmy.world 1 point 3 weeks ago (2 children) The first part made sense, then you contradicted yourself at the end^^ If the universe moves around you, you could literally see things moving. It would be the same as you moving relative to everything else permalink fedilink source parent hideshow 4 child comments replies: [–] crapwittyname@feddit.uk 4 points 3 weeks ago (1 child) Seeing things counts as something hitting you: photons. permalink fedilink source parent hideshow 2 child comments replies: [–] tomi000@lemmy.world 1 point 3 weeks ago True. But then thats not the exception permalink fedilink source parent [–] Derpenheim@lemmy.zip 2 points 3 weeks ago (2 children) Think about it more fundamentally. Instead of a person with senses, think of an object experiencing forces. Thats what an inertial reference frame means. permalink fedilink source parent hideshow 4 child comments replies: [–] ThatWeirdGuy1001@lemmy.world [S] 1 point 3 weeks ago But senses are just ways for an object to experience forces. I know if I'm hanging upside down because my senses are telling me my body is being pulled down from my head. I'm feeling the gravitational force pulling me down. An object moving in the universe is indistinguishable to the universe moving around an object. To any observer or to the object itself the forces experienced are the same permalink fedilink source parent [–] tomi000@lemmy.world 1 point 3 weeks ago Exactly. Seeing was just an example. The whole universe moving around an object would cause that object to experience forces. permalink fedilink source parent
