The ultimate Question of the Day ... just what IS Infinity, anyway?

I'm amazed I remember anything from high school, but that definition stuck with me. Another: infinity is when Pi comes out to an even (or final) number. No luck on that yet.
DJ - I don't remember a lot from high school either, (except that my Junior year was the best four years I ever had) but I also like the Pi definition. By the way, I heard that *they* - whoever *they* are - just ran Pi out to some god-awful bazillion numbers to the n-th power and still did not find a conclusion to the number. Probably ruined a good computer trying to find the answer.

Oh, right, Bridges ... here we are - six pages after the initiation of this one ... and finally - you cite the Nissan Luxury Car!
I saw it coming, too ... just surprised it took so long to get here ...
But, then - when it started out - two days ago ... it was in Main Photography Discussions ....
Now, it's been moved to - General Chit-Chat ... for whatever reasons ... I guess it's more ripe for cracks of this sort ...
Thanks for your input ... may the tides and misfortunes of that great Auto company - come and bite you in the ass ....

π can never EVER come out to be an even number, DJ ... no matter how many computers you go through trying to make that happen ....

Tony ... you had to do over your Junior Year three times, huh?
Sounds vaguely familiar .... Chemistry and Calculus were never my strong suits either ....
Oh, btw, Tony .... π can never EVER come out to be an even number ... no matter how many computers you go through trying to make that happen ....
If Pi is infinite, wouldn't the circumferences and diameters of any circle, regardless how large or small the circle, be infinite?

Roland .... I fail to see what the ratio of the circumference to the diameter of a circle has to do with the size of any given circle ....
π IS infinite .... but a circle's size can be given as a number, or it can be cited in reference to an existent object ... i.e. a quarter, a watch battery ... a 16" tyre, etc.
Regardless of how pi comes out, it has better be Dutch Apple.

Now, just after I got used to you citing formulas from an Algebra or Geometry book ... now you come at me with a comment about Dutch Apple Pi ....
Can't win with you, John ... can I?

No, just wear an aluminum foil helmet like the rest of us Klingons. 😈

Chris - doppleganger is a very good way of describing the effect of "lensing" and the effect it has.
DJ - I like that "where parallel lines meet" explanation!
John - Spacetime IS curved, and affected by gravitation. Since gravitational waves have only just been actually detected, we non-physicists can only guess. You may have seen the "ball weighing down a trampoline" graphic. That puts a two-, or perhaps a three-, dimensional perspective on it. While not totally accurate, it is what 99.9999999% of us can understand. (Now, I am stretching my limited knowledge and perhaps accuracy in the following statement: It is commonly believed by those - especially those few who truly understand quantum mechanics - the *idea* of there actually being *ten* dimensions out there - the three we see, plus time, and six [maybe seven, perhaps a greater number] more.) My wife says I can't even tell what time it is, so I certainly don't fall into that group!
Whew! I am certainly not a physics major, but John is right in wearing a hat for protection. I know, I do!

Tony ... I have enough of a time dealing with three dimensions ... now, you're telling me to accept ten .... !!!!
If all time is curved, then, at some point, we'll be retracing our own steps - no?
It can get pretty complicated - this stuff - huh, Tony?
Pi in binary= 11.00100100001111 sooo lovely!
Pi can be finite in a non-euclian, n-dimensional subspace. It is also where parallel lines meet and Al Gore finally gets to be President. And I finally master differential calculus.

I do have to admit, Bell ... I have a lotta trouble understanding how parallel lines meet, but, I have even greater trouble understanding how Al Gore gets to be Pres!
