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!!

If you think of the big bang as an explosion everything that was in the big bang when it was “set off” is still in the universe so in a way everything in the universe was at the centre of the expansion. To tell the “real” centre of the explosion you would need to observe the universe from the outside.
