Seeing how the Earth is not flat, Muslims must be wasting their prayers, right?

Think about it. They must pray in the direction of Mecca, but when they do this, because the Earth is round, the prayer would keep going straight and eventually leave Earth and go into the deep reaches of Space never to reach Mecca. Whereas if it were flat, it would eventually make it.. But it's not. So... Lolololololololololololololololololololo… Galileo must really hate Muslims.
