Interesting and confusing thought. If only space weren't so damn confusing in the first place.
If there were something it was expanding into, that something would itself have mass unless it was an absolute spotless vacuum.........wouldn't it?
Any mass at all and it kind of makes the idea of accelerating expansion kind of confusing itself.
This is just kind of random thoughts.......I wouldn't even call myself a star-gazer. Really haven't ever really got into space much more than seeing this kind of stuff posted.
Anyway, if there is "something", it likely has mass. At least in my noob-universe it would only make sense to have mass.
If there's mass, no matter how small, wouldn't it sort of accumulate on the outer edge of the universe as it expands? Kind of like bugs on the windshield of a car? Sure, drive for a couple days on the highway and you have a lot of bugs but not much added weight. Drive for a few billion years and all those little buggy bits and pieces will add up and start adding weight.
If that's the case, how is the speed of expansion increasing? Billions of years of accumulated "something" should slow things down, right?
This definitely seems like a better conversation to have in Amsterdam.
