Visualizing black holes and wormholes through raytracing

We explored the visualization of black holes and wormholes using code and ray-tracing programs. We introduced an advancement in astrophysics with the creation of a 4-color screen of a traversable Morris-Thorne wormhole, achieved through the utilization of flexible object-oriented ray tracer (FOORT), a ray-tracing software. Our research gives insight into the detection of black holes and wormholes in deep space; the 4-color screens are reflective of the gravitational lensing that occurs according to the laws of general relativity. We hypothesized that a Schwarzschild black hole would have a similar 4-color screen to a Morris-Thorne wormhole because neither object has angular momentum. In order to demonstrate the effect of angular momentum on gravitational lensing, we also explored Kerr black holes, since the nature of most cosmic objects gives them a spin. For wormholes, only a stationary, non-rotating, 2-way traversable wormhole was considered. Our hypothesis was supported by observing the similarity between the 4-color panels of the Schwarzschild black hole and a Morris-Thorne wormhole. We also examined the difference between the panels by constructing a subtracted image which highlighted the contrasts. This research sheds light on the difference between the gravitational properties of a Morris-Thorne wormhole, a Schwarzschild black hole, and a Kerr black hole. We concluded that the use of a 4-color screen can help grasp what black holes and wormholes do to photon particles in their locality, and how they would appear through instruments such as the Hubble Telescope in outer space.
