  • No. Because of the high temperatures, all matter in the early universe was an ionized plasma that would have scattered photons. The universe had to cool sufficiently to become transparent to light, which required on the order of hundreds of thousands of years after the big bang. The cosmic background radiation is the only remnant of this era.
  • We already do in a sense. Visible light is just one band of frequencies of electromagnetic radiation. Microwaves are another band. . Radio antennas can "see" the microwave echo of the BB everywhere in the universe. You can too if you have an old analog TV. It's the static you see on a channel not being used in your area.
