If the universe was fine tuned for our life...

It has rules, I get that. But what is a space continuum?

Space is a dimensional extant where things happen. By dimensional I mean the space has dimensions. In our reality it has 3 spatial dimensions and 1 time dimension(as far as we know). Continuum refers to continuity. It isn't broken up into chunks. In Second Life, when you teleport to a new land I imagine you are leaving one server and moving onto another. Each server is its own sub reality.

Consider simulation hypothesis which contends that our reality is just a simulation. I think it fair to consider our reality a valid reality even if it turns out to be a simulation....or a procedural generation as Rhythmn would call it. If our reality is a valid reality even if it is a simulation then why wouldn't other simulations also be valid realities?

I would be -amazed- if a mathematical description of your second life house was even remotely close to a mathematical description of your actual house......the game is checking files and addresses, not counting inches. But feel free to describe your actual house mathematically, and we'll see how the game engine would handle that, eh?

To mathematically describe the area of a room of your home, we would use the formula: Area=Length x Width. To mathematically describe the area of a room in a Second Life house.....we would use the formula: Area= Length x Width.
