Research Article Summary Sample – Interstellar Technology Throws Light On Spinning Black Holes



“Interstellar technology throws light on spinning black holes.” Institute of Physics Publishing, 02/16/2015,



This paper  sheds light on new knowledge about the nature of black holes with  a new computer code, Double Negative Gravitational Renderer (DNGR), developed by a London-based team of 30 visual-effects artists from the visual effects company, Double Negative. It was developed in collaboration with the Caltech theoretical physicist, Kip Thorne that simulated the never seen before graphical images of what would be seen if a camera was near a spinning black hole. The simulation reveals stunning images of the spinning black hole surrounded by over a dozen over(vmeste)lapping images of distant individual stars and also a thin bright plane of light that is an image of the galaxy that the black hole exists in. The simulation was done as a part of the making of Christopher Nolan’s Oscar-winning movie Interstellar. The images showed a spinning black hole which was dragging bits of the universe along with it and causing the caustics to stretch around the rotating black hole severely.

As the black hole hauls space into a circular motion and stretches the caustics around itself  many times, it causes multiple images. The results of caustics have been computed for a camera close to a black hole for the first time, and with the produced images, one gets an idea of what it is like to rotate  around the  hole.



To create the simulation of the spinning black hole, DNGR maps the paths of millions of the light beams along their respective cross-sections (that are evolving in real time) as they come into the black holes warped space-time continuum. DNGR created clear and very smooth images of a wormhole with a glowing accretion disk that has  parts that swing over and under the wormhole’s shadow and even  in front of the shadow’s equator; thus resulting in an image of a split shadow. This  phenomenon is a result of gravitational lensing, which is a process where the light beams from several locations on the disk or even from distant stars, are bent before arrival at the simulated camera; thus resulting in the mind-blowing surreal images of the celestial body. These images are of great value in various fields. Astrophysicists like Kip Thorne find sanctuary in the smooth images generated by DNGR as the accuracy of data in the profession is highly critical. The chief scientist at Double Negative, Oliver James, explained that DNGR mature and was even used to generate the images seen in the movie Interstellar. He also noted that they realized that DNGR was a tool that could be very easily adopted for scientific research. The image generated by the code was also a spectacle in the entertainment sector as DNGR was behind the iconic images in the movie Interstellar. The code enabled the tracing of distorted paths and shapes of the light beams rather than tracing the path of the individual light rays by incorporating Einstein’s equations.



I highly recommend provision of supportive funds for this research. I feel that the positive impact it  has on the world of science and many other relevant fields is a huge step forward in terms of technical enhancements. The diverse power of DNGR opens a new visual experience to astrology which is by far much more accurate than previous methods of image generation. This gives new insights into  the nature of the universe and celestial bodies in it. The images generated by the DNGR can also be a powerful tool in the education sector. Students can now run through a realistic simulation of several celestial phenomena with a cutting-edge accuracy. The value of this is unparalleled as it gives a hands-on experience of what it would actually look like if the viewer were  at the real place and time of the occurrence of the  studied subject.
