It's an actuarially sensitive question the major components being the age of the one seeking the desired result. If the one wishing is age 18 then the time horizon given for the fulfillment of of his/her wish Is a half century or more thus the wish can justifiably be ambitious such as an on campus stadium which for example allowing for advancement in technology could be constructed in thin air in some obscure location in the Everglades, transported to the convenient space above the present campus for a few hours a week. The crowed would simply transport themselves into their seats using their personalized molecular transporters. After the game the stadium could then be transported back to it's rural location. If on the other hand you are like me on the other end of the life expectancy curve who is cautious of starting to read any book of more then 500 pages I would settle for the simple miracle of all of our class including and especially Gray qualifying.
