The Speed Mach 20 is Quite Impossible in Atmosphere! How to Calculate the Speed Limit When Accelerating an Object in Atmosphere

This paper aims to respond to different mysteries which appear in news and blogs around the world about hypersonic flights, Colombia disaster, and hypersonic tests which are going on nowadays. People are really confused and wonder if, when we travel at hypersonic speed, the laws of physics change or if they remain intact. The laws of physics never change. It is we, humans, who have to respect those laws. In this paper, I will try to demonstrate and do all necessary calculations so people may find what is going on.
