All About Space

Hi,

It might sound ridiculous that time travel is possible using telescope, but as a matter of fact that is true. As as peep thru telescope you are not only looking at a object but you are looking at its past.

Let me explain that to you in my below example.
To see any object with your eyes your eyes need light from that object. But you know it takes time for light to travel from one place to other place in universe and the speed of light is constant and we are very well aware of the speed of light in the vaccum.
