well we would be using a telescope and with telespoce we can see "back in time".
but ive been thinking of this and i remember someone telling me that, the reason we can't see more than 30% of the night sky.

this is due to the fact that after the big bang, light was unable to travel through the univerese. but now that the universe has cooled the universe has become transparent.
so the reason why if the star does have a planet orbiting it and it is starless to understand why, you have to imagine, that when light from a star has a "light field" around it and this field is traveling outwards in all directions and once the field moves closs to a planet, then we are able to see the star.

ive have said this a number of time's on different forums but people say its wrong, but i guess it could be because im not making sence when i type it out, so tell me if it makes sence to you.?
