Ok..say time travel is possible by increasing the velocity of my surrounding enviroment nearing the speed of light whereas time would speed up so essentially I would travel to a future time. Now say I bulid this geosphere/motion sphere or what have you...and I put my wife in the sphere agreeing that we will let the sphere spin for one hour. Wife gets in....I stand there and watch the sphere spin faster & faster till it nears the speed of light then continues for an hour thereof..all done then...now say our theories were sound and time has actually sped up for the wife and she has traveled .say...1 week into the future just for argument...now since wifey is a week in the future she shouldnt be in the sphere when I shut it off because after all...I won't be seeing her until a week has passed right?...Ok...so what happened when I shut off the sphere...did she disappear into the future?..will I see her in a week?..and how?..would be cool if a flash of light and out she popped 1 week later.

Given an inner product bases, I know that using a basis, we can obtain an orthonormal basis by applying the Gram-Schmidt process. My question is, is that orthonormal basis unique? If I was to start using another basis, would I get a different orthonormal basis?

When treated with sodium iodide in acetone, benzyl chloride reacts much faster than 1-chlorobutane, even though they are both primary alkyl halides. Why does this rate difference occur?? also, would an SN2 reaction occur when crotyl chloride is placed in sodium iodide in acetone. If so, would it occur at room temp. or only once heated. Would an SN2 reaction occur if it was in silver nitrate in ethanol???-and if so, at room temp. or when heated? Thanks for any help!
