TL;DR
A Harvard astrophysicist has developed a browser-based simulation of a black hole that accurately models relativistic physics. The creator also offers a physical, mini black hole model for personal use, sparking interest in realistic space models.
Harvard astrophysicist Sasha Plavin has launched a project that allows users to explore a physically accurate black hole through a live browser simulation, and offers a miniature, real-world model for personal use. This development combines advanced relativistic physics with accessible technology, making the complex phenomena of black holes tangible for enthusiasts and researchers alike.
The project, shared on Show HN, features a browser-based simulation that models black holes with high fidelity to relativistic physics. The simulation demonstrates phenomena such as gravitational lensing, time dilation, and event horizon effects, providing an educational tool grounded in current astrophysical understanding.
In addition to the digital experience, Plavin offers a physical model of a black hole, designed to replicate key features such as the event horizon and accretion disk, using advanced materials and engineering techniques. The model is intended for display and educational purposes, allowing users to have a tangible object representing a black hole in their home or office.
While the simulation is fully functional within a web browser, the physical black hole model is still in prototype stages, with production details and availability to be announced soon. The project aims to bridge the gap between complex astrophysics and everyday accessibility, inspiring both scientific curiosity and artistic expression.
Implications of a Realistic Black Hole for Education and Science
This project matters because it makes complex astrophysical phenomena accessible to a broader audience, fostering interest in space science and physics. The combination of digital simulation with a physical model could serve as a powerful educational tool in classrooms, museums, and personal collections.
Moreover, it demonstrates the potential for advanced scientific concepts to be translated into tangible objects, sparking innovation in science communication and experiential learning. However, it also raises questions about the safety and practicality of creating physical models of such extreme objects, even if they are scaled-down and safe.

Background on Black Hole Simulations and Physical Models
Black hole simulations have traditionally been confined to computer graphics and research environments, primarily used for scientific visualization and public outreach. Physical models, on the other hand, have been limited to artistic or educational representations, often lacking scientific accuracy.
Recent advances in materials science and engineering have enabled the creation of more realistic models that can demonstrate key features like the event horizon and accretion disks. The idea of combining these with accurate physics simulations is a new development, driven by the increasing accessibility of high-performance computing and 3D printing technologies.
Sasha Plavin’s project builds on this trend, aiming to create a bridge between digital and physical representations of black holes for educational and curiosity-driven purposes.
“Our simulation captures the relativistic effects you’d see near a black hole, and the physical model allows people to hold a piece of that universe in their hands.”
