I'm with CAFG. Everyone make it a point to blurt it in one conversation.

Not at your level of math.
http://en.wikipedia.org/wiki/Euler%27s_formula
e^(xi) = cos(x) + i * sin(x)
-e^(pi * i) = -[cos(pi) + i * sin(pi)]
-e^(pi * i) = -[-1 + 0}
-e^(pi * i) = -[-1]
-e^(pi * i) = 1

If you take complex analysis, you'll discover that you can put numbers with i pretty much anywhere, including trig functions, logarithms, integrals, etc.

You can even put i in front of Pod functions.

Only if you're willing to deal with powerfully complex numbers.

Eh. You could be right, but I maintain that somewhere, some hyperintelligent aliens have stuck something weird into some star that makes it grow beyond a hypergiant . Well, it would still be classified as a hypergiant, but it'd still be freakin' huge.

Does anyone know approximately what percentage of the universe we see right now? I remember reading something that said that we actually see a great deal (40%?), but I have a feeling that that's a faulty memory.

Yay for cleverness.

Eh.. putting a percentage of what we see would be making the universe finite. Last time I checked the universe is infinite.

I'm ashamed to say this made me lol

That's strange. Last time I checked, it was expanding. Wait one damn second....

Thus infinite... what's your point?

You have a very strange definition of 'infinite', Shocko. What, so if a balloon keeps expanding a centimeter in radius a year, at any given time, its size is infinite?

infinite and instantaneous are two different things. If the balloon constantly gets bigger over time without permenantly stopping, shrinking or bursting, I would agree that it's infinite.

Even that way your argument is wrong.

By the time I post this, your 40% of "what we see" could easily be turned down to 0.04% by the universe's expansion.

When scientists say the universe is expanding, it means the mass in it is drifting farther apart from itself. Not that it is infinitely being filled with something.

Actually shocko, by induction the volume of the balloon will always be finite.
Lets say the radius of the balloon increased by 1 unit each iteration, with the original radius = 1

So for step r = 1, (4/3)*pi*r^3 is the volume, which is finite
for step r+1, (4/3)*pi*(r+1)^3 is also finite, and for each consecutive step it will be finite

This does differ from the universe in a few important ways though. The balloon example is self contained in that it only looks at the system consisting of the balloon and its insides.
The universe, however, doesn't necessarily end at the fringes of the mass, or the outer rim of what came from the big bang. Maybe our big bang was only 1 among billions of big bangs, huge collections of mass so far away that we can't see them yet. Who knows?

Perhaps the universe WAS made by god...

... lol jk.

Chances are, that's bullshit. I don't see the universe expanding hundredfold in maybe forty years since that's been measured. Anyway, I made no argument but rather asked a question. I think 40% is wrong, that it's closer to .04% or much less, but I wasn't sure about either.

What Vrael said is a good argument. Mine is that you don't know what infinite means.

Rule of googlism. 30 seconds or gtfo.

Infinite is a measurement of something not finite. For example numerics are infinite because you can always add 1 or more. Alphabet is finite with only 26 letters. Their is infinite combinations of the 26 letters if you can exceed 26 infinite amounts of time with any selection of letters.

Basically... It's infinite if there are no parameters. To my understanding the universe's molecules can expand in any direction without being stopped.

Thus infinite.

So, by your example... Any number of people standing in a line is considered infinite, because you can always add one more?

Get a dictionary.
