Distance of proxima Centauri.

Distance to the proxima Centauri. 

about distance code 21.78 I had told some weak ago. Now light travel and distance are two part of one subject. and this subject name is Time. or light travel and distance are two part of one Time. because if the energy has been spent in shape of light. then the light will be traveled anywhere. and in this two process. the time would be includ always. 

Bit it act is very different. which about you think. and a star is only like a unit. to which you can easily. but you cannot includ the matter of light speed in this. because you can only see in present process. which is stop from always or to which speed is very less. 

Three Condition of Period. 

each period`s happens three conditions. (1) Past, to which speed happens very fast from present. (2) Present, it speed very less like a stop condition. (3) future, speed to it 

happens very faster than on Past. PAST,, to the see of past. you often made the movies. and for see this movie you happens need of speed. and to the speed you use the  projector. so that you could see movie. So without projector you cannot see the past. 

because of past speed. and you was know about past speed. than you made projector. FUTURE, You not know about future speed. from this reason you could not make the future projector. Although it was very easy. PRESENT, Present always happens stop. 

no any speed of present. because to the see is very important speed`s to be end or finish. or when speed would be finish. then you see anything. or a car is running on the road. and you cannot tell about how many people are in this car. because it car is 

continuous in the past and future. and you are only in present. and present value is only stop condition. So by maths it is very very long chapter. to which about I shall tell later. Our first point is light year. about light year basically we use the wrong words. light year

is not any words. because light is servent of particle. if the particle quantity would be too much. then light will long travel. and their definition also different than on small particle. I am showing a Image to you. In which some important view about light year. after some weaks we shall start the journey of Proxima Centauri.
