Its not possible to actually see the light from the big bang as this light would already have passed far beyond us into the immensity of space. In fact as the universe expanded it did so slower than the speed of light so any light emitted in the early universe up until a point would also have passed beyond us, even the light emitted from the 'far side' of the universe. But based on the distance we now are from the big bang centre of origin and the time taken for earliest light to reach our current position from what was essentially the far side of the universe when those particular photons of light were emitted - is it possible to estimate this theoretical threshold point when we can see the earliest ever light from the primevil universe? Hope the question makes sense, it was kind of hard to explain my thinking.
