Everything we have heard so far plays off the fact that humanity knows next to nothing about the mysterious sphere that protects our City. Just what is the Traveler? My question is, why haven't we tried to find answers? Last time I checked, we're a nosy race of human beings. We obviously have spacecraft, so what's keeping us from flying into the Traveler's interior? Shields? Automatic defenses? Some sort of repulsive magnetic field? This question has been eating away at me for a while, so I wanted to see what you all think!
