Feels like that square should be a lot smaller
Exponential scales will do that.
I found this annotated version.
"Human experience" apparently includes anything from 0.01 seconds to 300 years, or 0.1 mm (diameter of human hair or ovum) to 10,000 km (cca length of Eurasia).
And less square
You can live between 0 and ~1XX years and you can travel between 0 and x km where the largest case for x is probably the people on the ISS.
So rectangle might make sense but obviously there is no chance for someone that dies as a infant to have traveled as far as an adult. Also the people on the ISS probably wont be the oldest people alive. So the edges would have to be cut off diagonally of sorts.
Or is this more like a "This is the scale of things that humans can observe" type of thing.
So we can see close stuff and really far stuff like stars and we can practically observe from milliseconds up to a century.

Sounds like a pretty human centric view
Perhaps parent was suggesting that anything in this chart is indeed part of the human experience, because we can --- in some small way --- comprehend or "experience" it. An intellectual rather than a visceral experience.
Or not, I dunno.
Reminds me of this SCP:
SCP-3125 is adapted for survival in an ideatic ecology considerably more violent and hostile than our own. (Here, "our own" refers to human head space: the set of all ideas which humans have or are biologically capable of having.) Because humans have no natural exposure to ideas as aggressive as SCP-3125, human minds have no protective evolutionary adaptations against it.

Oh, the anti memetics division! My favourite.
It's my first day.
