Speed of light ... From holy quran

Light is a form of energy which travels in the form of crusts and troughs. And and   another definition is that light is an electromagnetic wave which consist of seven colours and due to this it is also called WHITE LIGHT . And this is proved by SIR ISSAC NEWTON in 1666 , when he is working on light with the prism. So here is knowledge which will tell us about the actual speed of light.
       
Firstly  we need to know is that why r we not using its exact speed of light, the reason is its original value is.   tough n the original value is 299792458m/s.

 It is also written in the holy Quran about the fact that the speed of  light is 
                               

 Now we will discuss that how much time does light take in traveling from one place to another place in this universe
                  

 Now we will come to our main point that this speed of light can be calculated from a book which is written  14 centuries ago from now
 
Now  we will see some pictures or we can say pictures created by artist and these are
In this universe if someone ask you that which thing is absolute? And what will you answer, some of the person may answer that the speed of light is constant and some says that length of a particular string is constant.
But if I said that these things are not absolute what will you think. I know it is tough to believe but it is proved by sir Albert Einstein in 1905 and 1914 by his theories i.e. theory of relativity and general theory of relativity in these theories it is clearly written that nothing is absolute  except time.

 If you have any doubts please write them in comments and I will try to solve them.

How nanobots are used as artificial blood?

Platelets Function of RED BLOOD CELLS 1. Haemoglobin transports about 97-98% of oxygen from lungs to body tissues as oxyhaemoglobin. 2. Haemoglobin also transports about 23% of carbon dioxide from the body tissues to the lungs as carbaminohaemoglobin. FUNCTION OF WHITE BLOOD CELLS 1. Neutrophils act as soldiers gaurding the body .
