Many pesons have given answers . What they have said all that I know. Might be It's my fault in not describing the question properly. The question is that the scientists are telling that they have discovered some planet, star or milky way which is 100 billion years away. What I mean to say is that how can tjey tell that so and so star is so much distance away, without actually looking into it (atlest through telescope). To see that far away things, even by telescope it takes so much time (atleast some thousands of years). Hence how can they say?
