Several Theoretical Problems in Faster-than-Light Research

Huang Zhixun,Geng Tianming

Strategic Study of CAE 2007, Volume 9, Issue 4,   Pages 6-17

Abstract:

In the early stage of the universe, during the hadronic era, the lightvelocity was larger than c,  in fact was v=75c.This implies that light velocity has been decreasing in time slowly, from v down to the present valueScientists think it was aroused by the light-speed variation.This paper also discusses some problems of faster-than-light research profoundly, such as the velocity

Forty Years of the Faster-than-Light Research—Review and Prospects

Huang Zhixun

Strategic Study of CAE 2004, Volume 6, Issue 10,   Pages 6-23

Abstract:

Work on faster-than-light (superluminal) research has been going on in USA, Europe and PRC since theEinstein in 1905, velocities greater than that of light have no possibility of existence.In this paper, the author tries to bring about split-up to the different subjects of velocity's study，and then, suggests the definition of General Information Velocity (GIV) to make better discussion ofthose velocity concepts.
