Is stuff getting bigger? Is empty space appearing making everything further apart? Why isn’t there a definable center, isn’t everything going away from a point?
ETA: thank you so much for the explanations. I think this might be one I can’t get my head around without some more work, but I really appreciate all the help!!
In: Physics
Everything is moving away from everything else. There’s no center because there is no central point where everything is moving away from. Imagine drawing dots on a balloon and blowing up the balloon. The *surface* of the balloon represents the universe in that analogy. The surface of the balloon doesn’t have a center, all that dots are just moving away from all the other dots.
