THz Wave and Introduction to Superluminal THz Pulses Experiments;

Experimental investigation of the slow light and superluminal effects in high-quality three-dimensional colloidal photonic crystals

Quantum mechanics brings hope for the best on realization of faster than light (superluminal).

In this paper,the historic background of the study on faster than light(FTL)and the possibility of working within the frame work of special relativity are discussed.

the article briefely introduces of the theory "Faster than light", the present conditions of the study on faster than light, and gives on example which is in accardomce with faster than light and the theory of special relativity.

An exacter expression of faster-than-light;

However,no remarkable achievements have been made in the exploration of SETI,and only a little headway has been made in the faster-than-light research.

The paper uses colorful photos and a picture to record a guest star (a celestial body) that moved near the sun with a super velocity of light that was not less than three times of light velocity.

The article introduce the latest development of subluminal and superluminal group velocity, optical Bloch equations of three level systems, dispersion equation, the condition of carry out subluminal and superluminal group velocity and the advice on the new experiment.

The article gives a comment and analysis on the development of the experiment of subluminal group velocity and superluminal group velocity pulse.

Possibility of superlight velocity are discussed within the framework of relativistic theory.
