Default Re: Is 0.999999.... (infinite) equal to 1?

This is getting even more interesting now

xHx, I'm talking about theory. I myself want to understand the concept ('concept') of Infinity in depth.

We dont say the car traveled 999.999998 meters but 1 km. We CAN say the ant traveled 999.999 meters OR 99999.90 cm because we MIGHT need more accuracy there.
That's right and explains my point.

For example Canada is "infinitely big" for a snail, because it will never traverse through east to west in its lifetime.
Good point. Extending on this logic, probably Universe is finite (okay, don't jump on me!) because its way too big for us to see what's at the end. I wonder if it has been mathematically proven that the Universe is infinite or its still a concept?

...and if universe is infinite, why do people say that its expanding? [Out of context; sorry for that!]
