Oh jeez not this again Buz......
That space allegedly is bent does not address what property of space is capable of connecting the two ends of an absolute straight bar.
Yes it does. That is your problem. The bar is straight. In curved space. In what other way could it be straight if not in space whatever shape that space may be?
2. We've debated this before. Cavediver and all of the other physicist pros and buffs were here, yet my argument remains unrefuted. That space curves is the only answer we get, yet the question remains; what property of space is capable of connecting the absolute straight bar's two ends?
Maybe a better question would be what property you think the bar has that will allow it to not follow the path of curved space?
Your problem is that you are thinking of a bent bar in the sense of superman or somebody bending a straight bar by making on side longer than the other (think about it!)
A straight bar in curved spacetime has the two sides of the bar exactly the same length by any method of measurement made within that space.
The unrefuted Buzsaw answer remains: THERE ARE NONE.
There are. The problem is that you don't understand them and don't really want to undestand them.
