The telescopes out there in space now can see billions of light years into the distance – that’s billions times trillions of miles.
But think of it as looking into time: in a universe that may be only 10 or 15 billion years old, it means that we’re seeing not just distance but deep into the history of it all, more than halfway back to the big bang or whatever got it started.
In this hour of The Connection we’re peering into the corners of the universe.
