The temperature of the universe:
is constant.
varies between 20 to 6,000 degrees Fahrenheit.
has increased to about 10,000 degrees Celsius.
has cooled to about 2.7 Kelvin.
How is the "Big Bang" described?

The steady state theory holds that the universe:____
Looks essentially the same from every spot in it and at every time. It is homogenous and isotropic in space and time. It has uniform density so matter is continuously created.
Is homogeneous and its density is uniformly distributed. At the beginning the tiny dot expanded and spread out all the universe´s density.
Is a black dot that expanded to form all space, matter, time and energy. It is continously changing and it probably is going to crush.
None of the above
"The formation of matter is at a rate that maintains a steady density as the universe expands" is the
Static Theory
Steady State Theory
Big Bang Theory
