I knew the Gateway Project would be gigantic, but it's still amazing to see how it's grown. We're not even halfway done and it's already a sight to behold.
The size is a product of how far we need to travel. The greater the distance, the bigger the teleportation matrix needs to be. Of course, that means we'll also need a lot more power, but we've got a solution for that too: the obelisks.
Those bad boys are tapped into this place's main power supply, so in theory we can hijack that power for ourselves. The caveat is that we'd need a massive surge of it all at once, and we're not certain how to pull that off. We'll crack that code eventually, though. I'm sure of it.
