I don't think I get what you're saying even here. Probably my scientific mind which won't understand anything other than a definition or a theorem, but: that piece of text isn't really clear. How does zooming in on a circle get you more digits of pi? And by "proven its infinite" do you mean: it has been proven that pi is irrational?bassplayer142 said:Say you take pi and keep zooming on on a circle.

Well, like that, for example. Fractals are a cool example. Or all the points on a circle.But how exactly is something infinite constructed in our universe. It just doesn't make sense to me.
And now this is Chinese to me (which, obviously, I don't speak).Almost as far as saying that the everything is made out of something else on to infinity.

The way to think about it, is this:bassplayer142 said:Say you take pi and keep zooming on on a circle. You keep getting more digits but you never actually hit the end of pi. It has been proven to be infinite. But how exactly is something infinite constructed in our universe.
Why would you think this experiment has any bearing on the value of pi? It's certainly not the definition of pi, nor is it any theorem I know.bassplayer142 said:What I really was trying to say is this. Imagine you had a circle. You cut a string that is exact diameter of the circle (c=2*pi*r)and then you start at a point on the circle. You go around it 3 times getting 3. Zoom closer and you get 3.1, 3.14, 3.141 etc. Basically you are all saying that this is an approximation of pi because when you get down to the quantum theory nothing can get smaller. If so, then the real pi which is used in our world would be a rational number because It would stop there. If things kept getting smaller forever then pi would be irrational.

The concept of an infinite universe refers to the idea that the universe has no boundaries and is endless in size. This means that there is no edge or limit to the observable universe, and it continues infinitely in all directions. It is a fundamental principle in many theories and models of the universe.
At this point, we cannot definitively say whether the universe is truly infinite. However, based on current observations and measurements, the observable universe appears to be very close to infinite in size. The observable universe is constantly expanding and has no discernible end, leading scientists to believe that the entire universe may be infinite.
An infinite universe has significant implications for our understanding of time and space. It challenges traditional ideas about the beginning and end of the universe, as well as concepts such as the "edge" of the universe. It also raises questions about the nature of time and whether it is truly infinite or has a beginning and end.
It is highly unlikely that we will ever be able to fully explore an infinite universe. Due to the vastness of space and the limitations of technology, it is simply not feasible to reach every corner of the universe. Additionally, the universe is constantly expanding, making it even more challenging to explore in its entirety.
The idea of an infinite universe opens up the possibility of an infinite number of planets and potentially an infinite number of civilizations. This means that the chances of finding extraterrestrial life may be higher than previously thought. However, it also means that the search for extraterrestrial life may be more challenging and complex, as we may never be able to explore all of the potential places where life could exist.
