How to see the past?

When we look up in the sky on a clear night, we will see thousands of twinkling lights scattered across the vast universe. Some, of course are not stars even though they look like one. They are satellites, planets, moons of planets and other extra terrestrial objects. Do you know that when we look at a star, we are actually looking back into time? Light travels at, well, light speed (that is very fast in layman's term) and that still takes a few years for the light to arrive from the nearest star. So essentially we are looking at the star a few years back. At this very moment, the star could have gone supernova and exploded due to mass indigestion of its natives. And we will only know in a few years.

So let say we have a vehicle which is faster than the speed of light and we take this vehicle to a location very far from here, say 10 light years away. But we will reach there in only 1 year because we have hitched a ride with Captain Kirk on the Enterprise which was traveling at maximum warp speed all the way. Now, let say we also have a super duper telescope that can have an infinite magnification and we train the super duper telescope on Earth, I bet we could see ourselves ten years ago or nine years before we started our journey because the light has taken 10 years to reach that location.

What if Captain Kirk wasn't available? Well, there another way to look into the past. Take two mirrors of identical size slightly smaller than you. Place the two mirrors across a well lighted room facing each other. Stand behind one of the mirrors. Look into the reflection on the other mirror. On that mirror, there should be a reflection of you behind a mirror. Look closely in the reflection of the mirror in front of you and you should see a mirror with a reflection of you behind a mirror. As you look into the mirrors, you are actually looking into the past because the the distance traveled by light although insignificant at room size could be significant as you increased the size of the mirrors and the number of reflections that could be seen in the mirrors. Imagine a planet size mirrors, placed at the distance of the moon. The reflections in those mirrors could be light years apart and in the end you will be looking into history. Try it and be surprised!!!!
