During the evolution of modern technology one of the most desired dream of ours to see through Past and Future i.e. Travel through time.But do you know you can see through Past in time even Now.You must be thinking I am kidding but no I will explain to you what I am trying to tell you.
We all know from my previous post that speed of light is almost 3×10^8m/s.
So light travel from one point to another at a distance 3×10^8 m apart within a second.
(If you want to check out that post here is the link https://steemit.com/physics/@dpalash124/what-is-light-the-great-wave-particle-duality.)
Now if we take the beautiful stars in the night sky many of them are at a distance of several light year(Light year means the distance travelled by light in a year) so if a light ray emitted from a star at a distance a light year it will comes to earth after a year.Then we can see the star.So we are eventually seeing the image of the star which is one year old i.e. we are seeing through Past.If in between this year suppose the star get destroyed but still we can see the star. This is some astonishing fact that we never thought.
So light here behaves as a massenger which transport the massege from one point to another in this universe.
