Two astronomers accidentally discovered Response area, which is evidence of the universe expansion that supports the Big Bang theory. This is particularly strong evidence because its temperature is Response area. By observing this today, we can see what the universe looked like Response area.
Two astronomers accidentally discovered the cosmic microwave background radiation, which is evidence of the universe expansion that supports the Big Bang theory. This is particularly strong evidence because its temperature is approximately 2.7 Kelvin (-270.45 degrees Celsius). By observing this today, we can see what the universe looked like when it was only about 380,000 years old.
