I'm fascinated with space and all it's wonder but don't have much time to read about it. Recently taking some time to watch a few video's I've missed, and am enjoying them. But I'm coming up with questions that don't seem to mix well, or maybe it's just the analogies used that don't fit well?
The one that troubles me the most is this distorted space fabric theory, larger mass distorts fabric more and objects of less mass rotate about the higher mass ones ... marble in a funnel idea.
With that model I've seen people talk that nearing infinity the object of less mass will at some point prior to infinity hit the object it's orbiting around. But yes when I ask Google if the Earth is moving away from the Sun it tells me yes, and at an average rate of 15cm/year. source
- but how was this measurement taken? (3 points like GPS)
I assume one point, or maybe the only for all I know, was the Sun. So I ask Google, because I recall reading it years ago, is the Sun shrinking. It gives me a very good link that does not definitively say yes or no. source
But in my mind, the dark place that it is, one, the other or both have to be true for the marble in the funnel to be true, right?
If the Earth, according to General Relativity, should be moving closer to the Sun and someone's data says it isn't but someone else says that the Sun may be shrinking (at a rate faster than we're moving away I'd bet); then we would be moving closer to the Sun, right? (2 steps back, 1 forward sort of deal)
I'm just not sure what to search on at this point. So if someone could point me in the right direction would be great. Quite sure I'm not the only one who's been confused on these points, so there has to be something explaining the quandary.
