term2 week 4 (the universe that we are all looking at now)

On a cool sunday, evening as you lie on your soft couch and gaze at the stars, into the space, you think that the universe is rather a bizarre place to be in.But what i am about to tell you is really going to turn your world upside down.As you can see, our universe is really a big place there are certain planets billions of lightyears away, so by the time their image reaches the vunerable humans at the speed of light, thousands of years has already passed, so who knows what happened to that planet during that period of a thousand years.Yes, so by now you finally understand that what the scientists find really absurd and hard to accept is that the pictures of stars that they are observing now is really a picture of the past.
Perhaps it is imperative to ensure that not all of the people around the world knows about this or else they will really lose their interest in space.Therefore it will be imprudent for people like me to spread this peice of infomation around, right?
