I recently heard that the distance between the furthest galaxies in our Universe is calculated to be 125 billion light years.
Yet to my simplistic mind this is not possible. If the Big Bang occurred 13.7 billion years ago and nothing can travel faster than the speed of light, surely the furthest apart any 2 objects could be (moving in completely opposite directions) is less than 28 billion light years.
I don't for one minute imagine that I can be right so either I'm missing something obvious or I guess it's a lot more complicated than that.
Any explanations, anyone?
