RoTor_Ex··on Show HN: Galaxium, an experimental WebGPU space explorer
Gee... That's fucking insane! I like it!

Btw, how many hours do you have in a day to build a non-commercial beta like this in just a year?! :D

I found several issues: 1. Selecting Voyagers and swam back in time: • The Sun was leaving a strange trace of light while moving backward through space; • When voyagers reached the Earth in 1977, they ricocheted from it and flew back into space; • When I changed the selected target during the time simulation, it stopped and lost its simulation speed 2. I can't move my cursor with arrows or Cmd | Option + <> combinations in the "Ask AI" input field

And a few thoughts from me: • You missed the favicon =) • Behavior, when you first should click on the object and then click "center" to fly to it, is a bit counterintuitive and confusing. I personally expected scroll target changes automatically when I clicked to a different object • What do you think about adding the same scale across the whole Universe (esp. in the local stars group) that the Local Group has with vertical lines from the plane of the ecliptic? • Should you add a few more DSO objects like TON 618 in the "Featured" catalog?

It’d be interesting to hear how you see this evolving and what the original idea was. Are you trying to compete with other universe exploration apps, or build it more like a browser-based atlas of the Universe?
