Description

What would the world around you look like if you were staring at a
black hole?

This application places a black hole in the field of view of your
iPhone's camera and gravitationally "lenses" the resulting live video
feeds just as a black hole would warp the light from surrounding
stars. The resulting "Black Hole Vision" reveals interesting features
of black hole lensing, including a "photon ring" of strongly lensed
images around the black hole. The measurement of this photon ring
will be the target of future astronomical observations from space
with the Black Hole Explorer: an orbit satellite that will take the
sharpest images in the history of astronomy! To learn more about
BHEX, head over to https://www.blackholeexplorer.org/.

The code is open source and freely available on GitHub at https://
github.com/graveltr/BlackHoleVision, along with documentation that
explains the underlying black hole lensing equations and how they are
implemented in Black Hole Vision.

The code was written at Vanderbilt University by Trevor Gravely with
input from Dr. Roman Berens and Prof. Alex Lupsasca. This project was
supported by CAREER award PHY-2340457 and grant AST-2307888 from the
National Science Foundation.
