Basically says for a system of axioms sufficiently powerful enough to express arithmetic there are true statements that cannot be proven in the system. It's a mathematical result on the limitation of foundational issues.

>there are true statements that cannot be proven in the system

should be

>there are statements in the language of that system which cannot be proven/disproven

Can you provide an example?

There are statements about the natural numbers that are true, which cannot be proven within the language. That is not incorrect.

The continuum hypothesis if i remember correctly

Godel formalized the notation of the liar's paradox. Look into:

This statement is false.

What does his theorem even mean in real life?

It would be difficult to build a bridge from this kind of mathematics to areas one thinks of as "real life."

It's not at all clear to me what such a bridge is made out of, but some have attempted to apply it to philosophy of mind by giving formal descriptions to consciousness (ex: the mind is unable to prove or disprove certain statements about reality because it is, in some sense, like one of the systems Godel considers)
