Infinite means endless, period. A googolplex has 10,000 zeroes after it and it does not equate to infinity. That explanation was ridiculous.
Yeah, it does not equate to infinity because infinity is not a number. But still, a sufficiently large quantity in some application is the same as an infinitely large quantity. Should we take this to another thread?
How can you measure whether the universe is truly infinite or not? You can't, of course. You might as well try to disprove the existence of God. But our theoretical understanding of the universe, based on the expansion caused by the Big Bang, is that it is finite. I do not believe in an infinite universe and I do not believe in an infinite flat earth. And doesn't the concept of an infinite universe contradict Newton's theories of thermodynamics? I thought there was a limit to the amount of energy that can exist in the universe. I'm no expert on physics, so if I'm wrong, feel free to correct me.
I wasn't talking about the univers, I was talking about the flat earth. If the flat earth were very very large it could create the appearance of an infinite size in some aspect -- like the consistent pressure in the atmosphere, for example -- when it is truly not infinite, just like in my ridiculous explanation last post.
If the size of the flat earth were great enough (and / or there were great mountains around the perimeter) there would be very small time-rate-of-change of pressure through human history. The size of the flat Earth, or the height of the 'ice wall' does not have to be infinite to maintain a consistent pressure over a long period of time. It does have to be very very large, but not infinite.
