Sorry if this is so vague, but I was thinking about space and my brain can’t comprehend how the universe is infinite. To my understanding the universe “model” is that it’s kind of oval shaped and we come back right where we started. But wouldn’t that make the universe finite because there has to be something beyond that? Maybe I’m missing something and that’s why I’m confused.
In: Physics
Infinity just means “larger than we can comprehend or detect.” The universe isn’t actually infinite per se, if we determine the estimated age of the universe (13.77 billion years,) we can theoretically determine the maximum area of the universe, but the Earth is only 4.54 billion years old, so it’s physically impossible for us to detect anything farther away that 4.54 billion light years away, the signal can not have reached us yet. So whether it’s 4.55 billion light years away or at the edge of the universe it doesn’t matter, we can’t detect it so it’s infinitely far away. Moreover based on other resolutions that “inifinity” may be closer than that.
