  1. If an object is to free fall, where or what direction will it fall? In the direction the universe is expanding?
  2. Thanks for the information, Ok lets start again in a sense. Would I be correct in saying that if there was nothing in the universe (hypothetically) there would be no force, pressure...etc Only when something is present in spacetime would you have an effect? Actually only if you have 2 objects since they would then have something to react with (each other). I may be saying this (hard to explain).... Is it the object that has an effect on spacetime and the other objects react to this change in spacetime? Thaks for your patience, I would have replied earlier but did not turn on the send email button to responded messages.
  3. My question regarding Gravity and spacetime. I have seen example of the Trampoline effect when explaining gravity and 3 dimensional cube models. Here is what I thought was happening and I wondered if anyone can shed some light to where or not I am making any sense. In the trampoline diagram we see something entering an orbit due to the curve create in the spacetime grid. Kind of like something going down a drain so to speak. I picture a 3 dimensional grid, let’s say it’s made of a liquid sponge. I take an object like my fist for example and place it into the grid. The fist would be forcing the liquid sponge away from its self which would create pressure back towards the fist. I thought that this pressure or force would be gravity. So like on earth if one jumps they are jumping up into in the pressure of the compressed spacetime pushing back to earth. Each planet or object in space would be creating a pressure in the spacetime grid creates a friction and prevents it from speeding out of control. Ok that’s my thought......anyone? Cheers, Mark
