If we looked far enough out in space, could we actually see the Big Bang itself?
We can only see with electromagnetic radiation, the events that happened after about 300,000 years after the Big Bang. At earlier times, the universe was completely opaque because matter was completely ionized at temperatures above 3000 K.
We can never receive electromagnetic images of the Big Bang earlier than this horizon, however if we could use neutrinos we could explore back to about 1 second or so after the Big Bang, and with gravitational radiation we could see back to the Big Bang itself.
Presently such imaging technology is beyond what we know how to do.
