Question
Hi. How can a religious jew have an online business which has customer service available on Shabbos? From what I've read online, one can start the company together with a non-jewish partner who will take an eighth of the profits, but it seems that one must be careful that it should be a 'real partnership' - not sure what that means. Does this include decision-making? What if I outsource the basic level of customer service? Would that work? Thanks for any pointers on this.

I cannot find where I read that in ancient times when a synagogue had 70 adult men they started a new synagogue. Thanks for your assistance.

Question
I would like to know if there is scientific evidence on evaluation. Why don't Jews believe it and do we just not believe even when there's evidence?
