Xiao Chen said that at present, comet D3, which was partly in orbit away from the sun in 1996, has recently been able to detect its flickering light through solar telescopes.In the past, people have never observed such a twinkle in a comet far from the sun, so this flicker must be an unusual phenomenon.Xiao Wang said that usually people do not observe comets far away from the sun, and the flicker of Comet D3 discovered in 1996 was obtained by continuous and careful tracking and observation.
The statement 'Xiao Chen's arguments are self contradictory' can best summarize the methods used by Xiao Wang to refute Xiao Chen's point of view.
