FTA: - "Clearly we need a much bigger telescope to go back much further in time to see the very birth of the universe," said Edward Weiler, director of Nasa's Goddard Space Flight Centre.

Now at the birth of the universe, the light started leaving at the speed of light, the matter somewhat slower. Without time-travel, or faster than light travel, no telescope can witness the big bang, or even events "relatively" soon afterwards.

If there was a big bang about 15 billion years ago, that light is now 15 billion light years in every direction from wherever the big bang happened, with all the matter (well) inside a sphere of that diameter. Good luck catching the light.
