yes to my example bc it’s given by a scientist...
this example isn’t meant to show you colliding galaxies, it’s meant to give you an illustration of the expansion of the universe...
my mistake for not being clear...i reread it an i was kinda off.
the pennies cant rise in a ballon....is what i was getting at..
but i kinda see what you aee trying to say but it doesnt fit here.
the balloon is expanding into space. our open space that we are apart of and know its here because we are not all compressed.
so the balloon can expand......but do that same experiment inside a shoebox and lets see how far the balloon can expand with limits places on how it can grow.
which comes back to ......what are we expanding into.
space?
what is the construct of space? just open? a lack of formed or bonded atoms?
even space has to have a foundation.
its beyond my understanding how to define space if you are just in it.
please try to define space.
we are using a very primal definition. a crowded subway is nothing compared to 3million light years away from another galaxy. but to our naked eye....space can seem a bit densely populated.
so what is space again?
dark matter?
flexible atoms that some how hold us all into place but when we move we are able to separate those atoms like we do in water when swimming, so it bends around us but we just cant see it?
which then brings us to.....if space can be bent...then can time be bent?
and if spacetime can be bent......then the theory of wormholes can be true. as with possible time traveling backwards.
and if both of them can be bent then so can light.......and the speed of it must be redefined.. because we are measuring time by the speed of a proton which gives us the speed of light. but if certain object can bend light because of its density(blackhole)....then could space have an effect on the constant movement of light or the proton light is made up of??
does space have less dense and more dense areas like cloud? we dont know because we cant define space properly outside of what we have so far.
we are still in the 3x3 sandbox on the grand scheme,
