Born Hunter 17,907 Posted July 30, 2015 Report Share Posted July 30, 2015 Forgive my childish reasoning, but if something is constantly expanding then is it not infinite? Does it not only become finite when it stops expanding? TC While blowing up a balloon, is it constantly expanding? Yes, of course. Yet it also has a finite volume at any point during that expansion doesn't it. At no point does it have infinite volume, or will it ever do. So what your are actually saying is there is no such thing as infinity? TC In my opinion there is nothing physical that is infinite. It's just a mathematical concept. It's possible space could be but I highly doubt it. That's just my opinion though. 1 Quote Link to post Share on other sites

You know as well as I do that there is a perfectly good mathematical reasoning to say it is. But if not infinite (which I subscribe to as mind f***ing as it is) the what's on the outside? (No it ain't god Francie) Why does there have to be an outside? If space is a closed manifold then the dimensions of space are loops. There's no edge or outside in that model.

kanny 21,589 Posted July 30, 2015 Author Report Share Posted July 30, 2015 π is infinite so far it could be infinite in the sense we could never measure it quick enough ....I've heard it said that the universe may be expanding quicker than the speed of light if this is the case then how could we ever measure it it would just be in front of us all the time! ....heads starting to hurt now.

Born Hunter 17,907 Posted July 30, 2015 Report Share Posted July 30, 2015 π is infinite so far Pie only exists in mathematics. It's not a physical thing like mass, gravity, volume, momentum etc. In maths things can be infinite, in the physical world things just tend to infinity. Quote Link to post Share on other sites
mushroom 14,002 Posted July 30, 2015 Report Share Posted July 30, 2015 Considering maths has proven a lot of stuff in the physical world do you not think to give it respect BH?? Planes, satellites, GPS etc all run on maths and funnily enough π which is infinite Quote Link to post Share on other sites

Planes, satellites, GPS etc all run on maths and funnily enough π which is infinite Where have I not given it respect? This isn't a subjective opinion, pie is not physical. It's a number, not a physical entity. It's only the number of decimal places that pie has that is infinite and that's only in our decimal number system, a man made number system. Not a physical entity. Quote Link to post Share on other sites
mushroom 14,002 Posted July 30, 2015 Report Share Posted July 30, 2015 π manifests itself in everyday life. Without it a lot of shit would not be! In fact the world as we know it would not exist. Quote Link to post Share on other sites

Born Hunter 17,907 Posted July 30, 2015 Report Share Posted July 30, 2015 (edited) π manifests itself in everyday life. Without it a lot of shit would not be! In fact the world as we know it would not exist. Pi being the ratio of a circles circumference to its diameter. Those are real things. The actual value it takes, based on the number system, is completely arbitrary. It might as well be normalised to one. In fact it could just be left as a fraction, it really makes no difference. The concept of pie is important, it's place in geometric mathematics is important. It's value and the fact it has an infinite number of decimal places is basically irrelevant outside of mathematics.

Stop being coy and be honest Basically π is very precise and the bigger something is he more precise the maths has to be to explain/plot/journey to! That was my point Even simple equations can be undermined by chaos aka infinity Quote Link to post Share on other sites

Born Hunter 17,907 Posted July 30, 2015 Report Share Posted July 30, 2015 (edited) I'm not being coy, lol. Infinity only exists in maths, not in the physical world. In the physical world, physical things only ever tend to infinity, never reach it. Now the value of Pi might well be truly irrational and also have an infinite number of decimal places but that is only existent in mathematics. Decimal places are not physical things, they're purely mathematical and so this occurance of infinity is purely mathematical. In the physical world Pi is the ratio of a circles circumference to its diameter. Edited July 31, 2015 by Born Hunter 1 Quote Link to post Share on other sites

The effects of time are obvious. Like the effects of gravity. Changing them has real physical effects. Pi is just a ratio, it's just a number, it's value is purely mathematical. The importance of it in the physical world is that all circles obey the simple law that the ratio of their circumference to their diameter is the same, the universe over.
