In Cosmic Physics for $1000, Alex, "What is the Steady State Universe?"
What did Penzias and Wilson discover?
They discovered cosmic microwave background radiation is a major development in modern physical cosmology
What are the weaknesses of cosmic background radiation?
the weakness of cosmic back ground radiation as those radiation are left over of big bangs
What does the uniformity of cosmic radiation imply about its source?
The source of cosmic background radiation filled the entire universe.
What are the source of radiation?

What caused the cosmic radiation background?

What is the leftover thermal energy from the big bang?
The radiation left over from the big bang is found in the microwave region of the electromagnetic spectrum. As the universe expanded and cooled, the intense hard gamma radiation that existed became radio waves in the low gigahertz region, characteristic of a temperature around 30 Kelvin.
