Reply to comment by Dungeonmancer in The Europa Clipper mission may be as exciting as a manned mars mission and it’s only two years away by Wide-Escape-5618

Its a technology limitation. We can and should make transit times faster. The universe is so large that even speed of light is slow. We'll never be able to do anything outside our immediate neighbours with such slow speeds.

Absolutely. Technology is our limitation right now, but theoretically if technology keeps advancing eventually the speed of light will be our limitation.

Even the ludicrously fast speed of light is prohibitively slow to explore much of the universe. Perhaps we will find a way around it, but science hasn't come close to the science fiction yet in that regard.

It could be warp drives etc or some kind of effectively FTL travel are possible, but if not the speed of light might just be an impassable barrier preventing long distance exploration, which would be tragic.

I've always thought it as human lifetimes are the limitation, maybe it's not light that's slow in the universe but it's that were just too short in time to do or experience anything on large scales, but as you said maybe one day the speed of light won't be a barrier anymore 👀

I'd say light is definitely the limitation. If we could move at light speed we would still never reach 96% of the known universe because of it's rate of expansion, no matter how long are lives were.
