Alex .... I think our capacity to try and even consider the expanse of the Universe in distance is incomprehensible to our ' earthly minds ' ....such a ' task ' is too much to understand / comprehend
We use in everyday terms such as klm's and distance traveled by road or Air or Boat ... we can imagine this in our minds quite easily.
No wonder Pro' Brian Cox uses the word ' Vast ' in his documentaries to try and give us a ' grasp ' of how big and how far the Universe extends.
It's beyond my capacity to know how far or big it is.
