It will take MUCH longer than that. As for how long exactly, this is impossible to guess. But it will almost certainly be in the range of 1 to 3 years. It depends on how soon additional programmers can be brought to work on the project. The sooner that happens, the sooner SE will become cross-platform.

I wonder if in the final version of SE the size of the physical universe will be larger than 10x10x10 gigaparsecs.

The plan is for it to be unlimited. Not necessarily infinite, but definitely unbounded.

Are you referring to the idea of having the borders of the engine merged, i remember vladimir saying that once you reach one edge you will be sent to the other side in a seamless transition or will he actually increase the size of the universe cube?

The shape of the universe might not be a cube anymore, he has previously talked about a 4D shape, like a hypersphere or hypertorus. This would result in the user being able to fly in one direction and eventually return to their starting point without ever reaching an edge.

I see, so he's going with the seamless borders option, still can he increase the actual size of the hypersphere to be similar to the actual observable universe?

My only problem with the hypersphere idea is that wouldn't we be seeing some sort of cosmic horizon? Unless...light curves with it

I don't see why not.

Of course it does, just as roads and cloud formations curve along the surface of the Earth. The curvature is caused by the mass of the universe, which affects light.

So...given enough time, we should be able to see ourselves in every direction we look, almost like an eerie backdrop because in every direction we look, light has traveled around the hypersphere from ourselves back to ourselves. (Emphasis on given enough time)

This is impossible, due to the expansion of the universe (and anyway, the real universe is probably not shaped like that).

Also consider that the observable universe is a very small part of the whole universe, so, even if the curvature was not as low as we think it is, any information coming from "the other side" (the point itself?) would be so much red-shifted that its energy would be impossible to be captured anyhow.  :)

Yeah, the curvature might be negative so the real shape would be... an hyperbolic 3-manifold? I'm not going to be deepen the topic, since I just couldn't handle it!
The universe is not required to be in perfect harmony with human ambition.

I don't see why not.

And is it possible to implement this increased size, i mean does the engine have a limit to the size of the hypersphere?

There may be a limit, but I'm sure it's MUCH larger than the current implemented size. I'm not a programmer and I didn't write the engine, so I don't know the details of how large the universe could be made to be. Probably something like 6x1019 ly, as a maximum. Just a guess ;)
