    Can someone please help me with a query I have.

    If the energy released at the time of the Big Bang has not been slowed down by interacting with anything and hence is travelling at the speed of light, how is it possible to observe the beginning of creation since that energy would have already travelled beyond us, even if we observed a point at the other side of the Big Bang?

    The CMB is supposedly the radiation remnants of the big bang. That is what we allegedly see. The event itself as you say could not be seen since light moving from it would be travelling far faster than we (matter) could.

    I must admit I've wondered the same thing myself. I chalk it up to the fact that I do not truly understand relativity theory or the concepts of space-time or the idea of a universe without a center. Others do understand it and the CMBR was predicted by big bang theory before it was discovered.

    Maybe this will help.

    Robert Dicke, the man who "predicted" in 1946 the CMB invented the microwave radiometer in 1944 which became a component of radio telescopes. Easy to predict what you have already discovered.

    If Dicke had already discovered the CMBR, why would he say he had been "scooped" when Penzias and Wilson discovered it in 1964?

    Dicke invented the necessary apparatus to discover the CMB, showing that microwaves could be detected in all directions.
