Augmented Reality: Visualizing Black Holes

Black Hole Vision is an interactive iPhone app that lets users see how a black hole would affect the light in their real surroundings. Using the phone’s camera, the app places a simulated black hole into the live scene and shows how light from stars and objects bends and distorts around it.

How the simulation works

The app renders gravitational lensing effects in real time, so you can watch the characteristic bright ring that appears around a black hole. This photon ring and related distortions are produced by tracing light paths as they would be influenced by the object’s gravity, giving a hands-on demonstration of general-relativistic optics.

Notable capabilities

  • Real-time AR overlay that merges a simulated black hole with the camera feed.
  • Interactive visualization of lensing phenomena and the bright photon ring.
  • Educational descriptions that explain the physical processes behind what you observe.
  • Free to download and use on compatible iPhones.

Open-source code and academic partnership

The project is released with open-source code and supporting documentation hosted on GitHub, allowing curious users and developers to inspect the implementation and underlying science. Researchers from Vanderbilt University contributed to the development, helping to ensure the visuals are grounded in contemporary astrophysical understanding. The team also intends for the app to be complementary to future observational campaigns that aim to image black holes more directly.

Other apps worth trying

  • Toca Life World — a creative storytelling app (free)
  • Additional astronomy and AR tools available in app stores can offer alternative ways to explore space concepts

Getting started

Download the app on a compatible iPhone, grant camera access, and point your device at a scene with some visible sky or bright objects. The overlay will appear and you can move around to see how the simulated gravitational lensing changes with perspective.
