So, help in correcting and in re-expressing them in better English is always appreciated. I want to learn the language better.

I completely agree with you that it never hurts to substantiate any doubtfull statement by an equation or a fact.

I have provided plenty of equations and facts to substantiate my statements, and very rarely see similar substantiation from anyone except Bruce. (It may be the case because Bruce has certain text in his hands - GR textbook or so, although it is not clear to me if Bruce can solve problems on his own). Anyway, a fact or an equation is better than thousand words.
