Hi Product Hunt, I'm Subham, the maker of Reality ASM.

Why I built it: in school, space was a few flat diagrams and numbers like "the nearest star is 4.24 light years away" that nobody could feel. We learned the Solar System, the stars and galaxies as separate chapters and never saw how they fit together. Many students, me included, understand far more by seeing and playing with something than by reading about it.

So I built a simulation platform where students can explore science instead of memorising it. The part I am proudest of is the Universe Map: one continuous map you zoom through, from the Solar System on any date, out to over 100,000 real stars, the Milky Way, more than 11,000 galaxies, and finally the edge of the observable universe. Tap anything to read what it is and how far away it is. Everything comes from real scientific catalogues (NASA JPL, HYG, OpenNGC, the Open Exoplanet Catalogue), not artist drawings.

Who it is for:

- Students who want to see and try the science, not just read it

- Teachers who want to show a concept in class instead of drawing it on the board

- Anyone curious about how big the universe really is

Beyond the map there are physics, chemistry and maths simulations: rocket launches and orbits, pendulums, waves, circuits, reactions and graphs. Every number on screen is calculated by a real science engine, and an AI analyst next to each simulation explains the result in plain words.

You can try it with a guest account, just a name and a username, no email.

The feedback that would help me most:

1. Where did the Universe Map confuse you, or where did you get lost?

2. Teachers and students: what would make this useful in a real class?

3. Did anything feel slow on your phone or laptop?

I will reply to every comment today. Thank you for taking a look.
