Yes and the velocity of light is 3lakh km/h
in the eqation E=m x c 2 E-enegy created
m-mass of the body
c-velocity of light ..... Note- the velocity and speed are not the same quantities.Velocity is vector and Speed is scales

Yes....and can u imagine that scientifically a real time machine can be made according 2 the formula of E=mc2 . But the vehicle must run faster than light speed. Its toooooo difficult but very interesting.

Yeah..it's gotta do something with photons and protons..Einstein speculated that space was not absolute and depended upon time and that time in turn is not absolute and depends upon space..

Ah..those stupid showoff scientists gave the approximate velocity..stupid..the real one and the approximate one have a difference of 467 miles per second!

The speed of light was the speed in complete vacuum and light travels much more slowly through air and all light falls in the electromagnetic spectrum(a synonym of light is electromagnetic waves(torit-chumbok in bengali)).The electromagnetic spectrum consists of light from short(micro..nano..or even shorter) waves to high velocity low frequency long waves.The visible light,or VIBGIOR(Violet,Indigo,Blue,Green,????,Orange,Red) is a part of the electromagnetic spectrum and consists of,as you see,all rainbow elementary colours(colours like brown are known as compound colours).Visible light lies approximately at the middle of the electromagnetic spectrum.Other waves like X-ray,Gamma ray,radio waves,etc. are the other divisions of the electromagnetic spectrum.Light,like matter(according to the e=mc2) curves or distorts the space-time fabric.Light waves are also far more strong and powerful than weak gravitational waves..so(oops! Run out of information.Note to self:More research needed just here.)
