sophiaserpentiaThe universe is expanding in three dimensions, right? So might it also be expanding in the fourth dimension as well?
And what would "expansion in the fourth dimension" mean? Is this what causes us to experience the passage of time? IOW, just as the universe continues to expand outward, does it also expand into the future, making the present moment the outermost boundary of the universe?
