Hey Greg, i know this doesn’t necessarily only apply to the YJ show as it also applies to the comics and to Marvel, but what is the Earth-16 in-universe explanation for how the Justice League/superheroes seem to have the technological capability of travelling interstellar distances across the Milky Way Galaxy but regular humans/Earth governments/space agencies seem to be in the same place technologically as we are in real life when it comes to space travel and exploration? i noticed that in the first episode of Season 4 we saw a glimpse of the Curiosity rover on Mars, which is actually what led me to ask this question. why aren’t there already human colonies on Mars or on other celestial bodies in the solar system or even outside the solar system when humanity on Earth-16 clearly seem to have the technology that would allow them to do so?

of course this is assuming that Earth’s governments and space agencies on Earth-16 are in the same position technologically as us in real life but if that’s genuinely the case, then why is that compared to the Justice League/superhero community?
