Re: Possibly a Stupid Question...
"But who says the sheet is flat in the absence of matter? If is wrinkled,"
So you are saying the universe is a wrinkled sheet like on a recently slept in bed, and we are just waiting for the cosmic housekeeper to make the bed, and straighten out physics until the heat death of the universe makes us all go to sleep once more? So the real question is, will humans be sent to bed without supper, or can we stay up late watching the more confusing episodes of Doctor Who?
