Journal of Cosmology, Filaments and Astrobiology JCFA 2834-0221 10.54216/JCFA https://www.americaspg.com/journals/show/2335 2022 2022 Malang Institute of Agriculture (IPM), Malang, INDONESIA Victor Christianto It is known, despite special theory of relativity has been widely accepted, in our recent draft submitted to this journal it is shown that some experiments have been carried out suggesting superluminal wave propagation, which make Minkowski lightcone not valid anymore. Therefore, it seems worth to reconsider the connection between elastic wave and electromagnetic wave equations, as in their early development. In this paper we will start with Maxwell-Dirac isomorphism, then we will find its connection with elastic wave equations. 2023 2023 08 10 10.54216/JCFA.020201 https://www.americaspg.com/articleinfo/32/show/2335
