Yeah my cat recently swallowed my Fiances Pearl earrings. I called the vet and they just told me to keep an eye on her and her stools... oh joy... but anyways I was wondering if a pearl will dissolve in the acids of the stomach. I dont think it will but I was wondering if anyone might have some better idea or information to lead me to my answer! Thank You!

You have to get as close to $1 with the sum of 1 or 2 spins without going over $1. The wheel has values from 5 cents to $1 in increments of 5 cents. Three contestants compete for who can get closest to a dollar without going over. If you spin a low value and decide to stay, you risk the person(s) after you beating you. If you spin a high value and decide to spin again, you risk going over. So what value is the cut off of when you should stop or spin again? This should differ if you are the first of the three to spin or if you are the second. If you are the third, it is easy because you know what you have to beat.

Man has been known to make mistakes. What if the theory of the Big Bang is incorrect.? Is it possible that the evidences that scientists have used are based on an illusition? ie: just like if you were stuck in a desert and you see a mirage but once you get closer you realize it is not there. What if space is warped (ie: waves) and what we see is just a part of space. ie: the first crest. If we actually go to the first crest, we may see the second crest. The theory that everything is moving away from each other may-be true up to the first crest but what about beyond this crest. If we believe that there is a beginning then there must be an end. As we know nothing can come from nothing. It is lot more plausible to believe that the universe always existed and things are always changing and moving around in a random fashion.
