Question

What question has no valid answer?

Answer

Well, no question has a valid answer until it happens. If I flipped a coin and asked you what side will this coin land on? and you chose heads, it has a fiftyfifty chance of landing as tails. Therefore that question didnt have a valid answer until the coin stopped moving. Every question therefore has no valid answer unless it has already happened.brbrbrYou might as well tell someone to dig half a hole in the ground
