Isn't infinity just a concept? Can an undefined number be bigger then a defined number?

Isn't infinity just a concept? Can an undefined number be bigger then a defined number?

I am a total noob when it comes to mathematics.

Infinity is big, and stupid, and fat, and ugly.

Infinity is a big number
for you

Infinity doesn't exist in nature, so yeah it is a concept, just like elves, Santa, God, and good rap music.

Infinity isn't a number
it's a state

It might. It seems as though it doesn't, so yeah, it should be thought of as a concept until proved otherwise.

so for example, if i say:

1, 1/2, 1/4...

this infinity is definitely not bigger then 3. So we have to mention which infinity we are talking about?

Think this way. If the universe can be measured it means that its finite.

Just like if you locked yourself in a room full of numbers with you being a determined entity made entirely of nothing else but numbers. There is still going to be a finite ammount of possibilities you can reach and you won't be able to go beyond that.

Mathematic predicts that infinite is something that expands indefinitely within the realm of possibility. That's just abstract line of rationale and impractical. As we all know it the possibility is just a fraction of statistical thinking which isn't concrete thinking. Imagination, without traces or curves giving any distinction to its form and being, a skeleton of nothing real. Infinite is plain and simple, a universally refutable concept of the inexistence.

Math doesn't exist in nature you massive fucking retard.

Your thoughts are part of nature, whether it's relevant is another question.
