Infinity doesNOT exist in Nature , the whole concept of infinity is FUN but utterly preposterous .
There is no such thing as a perfect circle , Pi goes on for ever (thus it's wrong ) For the perfect circle you would need space to be infinitely small. If pi did , actually come to an end after a finite number of decimal places ,then you'd probably solve so many questions in physics , but it doesn't. If it is truly infinite imagine the decimal digit getting stuck on an infinite number of sixes or an infinite combination of 123456789123456789 etc. etc. ( that doesn't truly make infinity preposterous but lets move on )
Forget the maths , lets imagine the famous chimp and type writer concept
So....you sit your chimp infront of a typewriter and give it infinite time (and paper/ink!) to type "random" characters , the idea goes that it will eventually type the complete works of shakespear . But surely ,every book ever written , and surely every book everwritten in every language possible with the typewriters character set. It starts to get crazy! How about every book ever written in every language ever written with just one typo and then every possible typo possible and so on. BUT here's why Infinity breaks down , what IF the chimp gets into a sequence of typing the complete works of shakespeare over and over and over in sequence , and simplified , what if the chimp just hits an infinite sequence of "a"s If this happens ( and it WILL ) then there's no chance and I mean absolutely no possibility what so ever of completing the infinite sequence of the complete works of shakespeare etc. IT fails in so many more ways.
And my Point:
If the infinity sign appears in an equation that is trying to define a natural process ,then it's wrong , it IS by definition , ludicrous.
GR is very very good , BUT it does not explain a black hole correctly
I hope in my lifetime , this problem is solved.
