That is what I get when I give you the benefit of the doubt, muggle nonsense? It's possible to travel between realms using magic, yes. But do consider it a little. Think about what infinity truly means, won't you, and you'll see the impossibility of that statement.
Not too much, though. I have heard about several wizards who worked on arithmancic problems of the infinite, thinking it might lead to limitless magical power. It wasn't terribly good for their minds, as I understand it.
Preya is a very great change. But you know from my perspective, I am from just the right time and you from seventy years in the future!
