Comparison of Different Detection Approaches of Black Hole

Abstract

The black hole has been investigated by the scholars for many years since the proposal of the concepts. Contemporarily, with the help of the state-of-art detection facilities, plausible observation results with more detail and diagnostic information have been achieved. This study investigates the two widely utilized detection methods and demonstrates a comprehensive conclusion about the method that researchers used to detect or discover the black hole. To be specific, this study mainly focuses on how the gravitational lens and gravitational wave method used to investigate the black hole, and it compares the cons and pros of the two specific method. In addition, the current limitations regarding to the nowadays detection scenarios have been discussed and the future prospects for the improvements have been clarified accordingly. This research can give people a fundamental understanding about the technique that used to discover the black hole. These results shed light on guiding further exploration of black holes as well as the proposals of the detection paradigms with better performance.
