My understanding is that the universe is always expanding and is therefore Infinite. But if we had the tools and we could break the speed of light could we measure the different stages of infinity? The explanation that the universe started with a big bang then expanded and suddenly expanded by infinity does not make too much sense to me. We are able to measure a less than 1 millisecond after the big bang. That is still something and a number that we can measure from the stages to infinity isn't it? An example would be that we could measure how "big/long" "the end" of the expanding universe was 4 billion years B.C.
Please give me an explanation as to why my "theory" is stupid/asinine seeing as i am not a scientist nor a well educated Pearson.

Thank you.
