I got some ideas.
I’m thinking everything is on a different plane. I think you’d only be able to go down a plane initially. You get to something by moving toward it. My initial thought is that gravity is a way if all planes have gravity or pull. I think they do. The only problem with tt is how do you make something massless to tt or do you even have to.
I think e=‘mc2 or theory of general relativity is accurate for what we have observed. My initial theory is it only applies to are galaxy. It could be bigger. If we’ve observed bigger than our galaxy our whole whole concept of solar system galaxy etc is wrong. It should be broken down into different gps. Everything is in space time so even at micro levels it should be broken down in gps. As you scale it or make it smaller the way gravity works changes.
