#Science_is_absolutely_amazing_and_wonderful

Let me give you a wonderful example. Open your mind and read…it’s amazing ….

Some of the basic science before proceeding:

1. How do we see any object?

We see an object when light radiating/emanating from any object falls upon our eyes and its image is formed on our retina. The light may be a reflection of light falling upon the object or the object itself radiating light.

2. What is light year?

Light year is a measure/unit of distance. Astronomical and extra large distances at the level of galaxies are measured with this unit. The speed of light in vacuum is 299,752,458 metre/second. Thus if any object is 1 light year away from us than that means that the object is at a distance of 9.460530×10^15 metre.

Now coming to the main point of this post. We very often (or atleast sometimes for many of you) read reports/articles etc. wherein we read that the following Observatory or research centre or space centre has observed a star or extra terrestrial object which is at a distance of following thousand/million light years from us.

Now whenever you hear such reports etc. then what you decipher from that??

Any thought on that???

Let me try to explain an astounding and amazing thing about this. If we are seeing (here ‘we’ means high resolution and extremely high capacity telescopes etc.) an star which is at a distance of 1 million light years away from earth, IT ACTUALLY MEANS THAT WE ARE SEEING THAT STAR WHAT IT WAS A MILLION YEAR AGO AND NOT NOW. THE STAR MAY NOT EVEN BE IN EXISTENCE TODAY OR SIMPLY MIGHT HAVE BEEN GOBBLED UP BY SOME BLACK HOLE. We are seeing what the star was a million years ago and light has taken a million year to travel the distance to form that image on our eyes/telescopes.

Don’t you all think that it’s amazing? It isn’t amazing that we might be seeing something which no longer exists at all?

Now tell which of your religious books can have such an awesome and wonderful things as this….
