I have heard ...Thanks for pointing this video out. I have heard Uthman Badar in other debates and have noticed (but not been surprised by) his naïveté.<br /><br />His counterexample to the real world existence of infinity is hilarious: "Let there be an infinite number of people in a room..." Forget the fact that "infinity minus five equals infinity" makes perfect sense (whereas he thinks he got a contradiction of sorts), and focus on the premise. How on earth can we, in the real world, have an infinite number of people in a room? OK, I see... we need an infinite room :-)<br /><br />Now, the problem is on the meaning of "real world existence of infinity". Clearly, Badar has some kind of geometric viewpoint. He wants to "see" infinity in space. But how about subtler notions of existence of infinity?Takis Konstantopouloshttps://www.blogger.com/profile/14675216467783238403noreply@blogger.com
