On a number line, where is the “center” of infinity? 0? Maybe. But -59264920.5849201 is just as valid as the “center”.

We cannot speak with any definition about anything beyond the observable universe. We can speculate, but due to an increasing expansion of the universe things are constantly falling out of our observable universe. And technically *you* are the center of *your* observable universe. Someone down the street or in the galaxy over would be their own center of the universe.
