so there's the obvious drawbacks which i may list later if i have the characters but the idea runs thus...
we know that a theoretical incompressible rod of incredible length when pushed at one end would not move at the other immediately (if it were a lightyear long then the movement would take more time than the light took to get to the other end). imagine this rod were formed in a slightly incomplete circle with ends A and B. if A were pushed in a circular motion the long way round to B. before that movement had travelled to end B a filler is placed between A and B (completing the circle) would the eventual movement in B then force A round further again moving B and resulting in continuous motion? i realise the limitations of this idea in terms of size, friction etc. but has it been theorised before?

I've read so many books on astronomy and star-gazing, but I never had a chance to really look into space. As a beginner I heard that binoculars are good for starters, before buying an actual telescope. But which ones are good? 7x50, 11x70, what is the best one? Are they expensive? What is eye relief on binoculars? Has anyone ever had a binocular for star-gazing? And what can you actually see in space with one? Oh god, I know too many questions....Sorry.
Thank you!
