Could you build this?
Partial The front-end WebGL presentation is codeable with AI help, but gathering, normalizing, and rendering astronomical catalog datasets accurately at cosmic scale requires specialized domain data handling.
What it would actually take: The architecture requires a custom WebGL/Three.js rendering engine using logarithmic depth buffers or multi-camera setups to handle astronomical distances from 1 AU to 13.8 billion light years. Data must be ingested and normalized from real catalogs like Gaia, HIPPARCOS, and 2MASS into spatial octrees or hierarchical level-of-detail formats. Expertise in 3D computer graphics, shader programming (GLSL), and astronomical data coordinate systems is necessary.
