I agree. MacGyver > Mr Astronaut that finds a talking ship.

It's all about using the right dimensions to get where you want to go. Folding one dimensions on itself or using the dimension above (5th/6th) means you can instantly move from one point to another in a completely non linear fashion as viewed from the dimension below.

You make it sound easy.

Sadly the problem is that the curvature of space time (expressed as a tensor) is proportional to the energy density at that point. To 'bend' any dimension to the extent that significant distances become travellable requires an energy density greater than anything known to man.

According to current scientific belief

Sadly the curvature of spacetime in the presence of mass/energy is experimentally proven, so even if GR turns out to be a crock, any replacement *has* to have the same results in that area.

Thats assuming that in the bigger picture we would be descibed as 'inteliigent life'. I would hope not tbh.

Calvin of Calvin And Hobbes had it on the money I reckon - 'I think the surest sign that there is intelligent life out there in the universe is that none of it has tried to contact us.'

That's a bit of a stretch! You've got absolutely no proof that the 99.9% you discount have *never* broadcasted anything. The distances are so vast that perhaps the signals simply haven't reached us yet. Certainly, the relatively tiny amount of time we've been able to broadcast signals, and the vast distances involved, means that our signals will only have reached a tiny fraction of the visible stars. Consequently, the chances our signals have reached a planet populated by an intelligent species capable of intercepting and interpreting them is at best slim.

But, if there were able to come here in the first place then it would mean that our signals wouldn't need to have reached their planet, would it?
Any beings capable of coming here would, as they certainly wouldn't be anything resembling local neighbours, have to be considerably more advanced than we are. It follows that once that level of advancement has been acheived then it's likely they would've begun to explore "out there", and as I said earlier "they" would be from somewhere that's a loooong way from here. Our broadcasts could and would be intercepted en route.

But without our signals reaching them, how would they know we were here? Also, who's to say that the speed of light would be a barrier to more advanced beings?
