I totally agree THE , there was only one force which quickly broke into different kind of energies, but still I talking about precursor of that on singular force. I have not seen the edge of the Universe, however, some of the satellite telescopes have. Universe is not edgeless. However, there are different theories about what forms the edge. Is it the dense electromagnetic field or is it the light speed horizon (that the limit which is more that 14 billion light years away & light cannot reach us from there)
