another project hail mary observation:

Rocky’s gift to Grace immediately reminded me of the Voyager Pulsar Map

When Rocky gives him that little model with all the connected points and lines, Grace somehow catches on almost instantly that Rocky is from 40 Eridani. And at first i was like how the hell did he recognize that pattern so fast???

And then it clicked for me...

It visually mirrors the pulsar map placed on the Voyager probe. I'm aware they work differently because the Voyager Pulsar Map is about locating Earth in the galaxy using fixed pulsar landmarks, while Rocky’s model is just mapping local star distances from 40 eridani to systems like Tau Ceti, but it’s just cool because they’re alike in the way they both use spatial patterns instead of language to show where something is from and how to get there.

The concept is so similar that your brain immediately associates it with “location,” “origin,” “this is where i am from”

If you don't know, the pulsar map on Voyager was basically humanity trying to leave behind an address in space. If extraterrestrial life ever found the probe, the map could theoretically help them trace where it came from. It was humanity saying: hey, you found our probe. Please return to Earth!

I like to think that is why Grace understood it so quickly. Because even without language, the idea behind it is strangely universal. Every intelligent life form wants to know the same things:

where are you from? how far away are you from me?

My favourite space images from Hubble space telescope. Thank you so much for giving us the stunning visuals of galaxies, stars and nebula. Happy 35th anniversary to the Hubble space telescope 🔭
