And lets not forget the ever popular, “We’ll never be able to go there anyway”.

because of the vast distances between stars, I believe at least one of three things need to be true.

1. Zero point energy.If you're a poor bastard stuck travelling the cosmos at sublight speeds, it's gonna take you a long time to get from here to there. Unless you're able to accelerate to at least a modest fraction of C, you're talking decades or centuries. Even if you're able to implement some kind of hybernation protocols, you still have to have power and life support when you come out of it. Even nuclear power is not attractive when you'er talking those kinds of time scales - especially since you will, by definition be pretty darn far from logistical support.
2. Faster Than Light (FTL) travel is possible. If you can do FTL, then you hopefully are no longer stuck for decades travelling from star to star. Hopefully FTL travel doesn't also require a ZPM to get moving that fast. Even travelling at C, you're still movnig pretty slowly when you consider cosmic distances. If you're ever bored, figure out how long it would take you to get to Alpha Centuri travelling at one AU (~93 million miles) per second.
   
3. Travel through wormholes/folds in space. This avoids all the mucking about of physically crossing the distance you want to travel. Hopefully you'd be able to generate the wormhole at will without having a ZPM to power it.

Personally, I hope that all three are possible, and BTW, I want a ZPM to run my motorcycle.

As an interesting ‘homework’ assignment.

Figure out how long it would take to accelerate to 90% of the speed of light at one gravity of constant acceleration.

Then, of course as you approached your destination you would then have to decelerate at one gravity for the same amount of time.

There are a lot of very interesting little understood things going on at the sub atomic level which could potentially be harnessed for our own use.

“Spooky action at a distance” as Einstein called it or quantum entanglement has the potential of communicating instantaneously over billions of light years.

Obviously we aren’t going far right now but that’s what science is for. Its also possible that we simply haven’t stumbled across or conceived of something extremely simple
