Paradox of Schwarzschild Blackholes(MinTae Kim).pdf

The meaning of the singularity of Schwarzschild metric at the Schwarzschild radius was reviewed based on the relativistic kinetic energy, in order to get to the nature of Schwarzschild black holes which have only mass as physical quantity. In the relativistic frame, the maximum kinetic energy of a particle goes to infinite, as its velocity approaches the speed of light. When taking account of the relativistic kinetic energy at the Schwarzschild radius, the escape velocity from a massive spherically-symmetric object is less than the speed of light, indicating no singularity at the Schwarzschild radius. It further means that any Schwarzschild black holes cannot exist in the relativistic regime.
