Post by: doit_the_clown on Mar 21, 2017 The conditions in the early universe at the time that matter became decoupled from radiation were (in terms of age t, peak background wavelength , and equivalent temperature T)
A) t = 2 × 1011 years, = 1 mm, microwaves, T = 3 K B) The universe was never radiation-dominated since matter has always dominated by generating the gravitational field into which the universe has expanded. C) t = 3 minutes, = 0.3 m, near UV, T = 107 K D) t = 500,000 years, = 1 m, infrared, T = 3000 K Title: Re: The conditions in the early universe at the time that matter became decoupled from radiation ...
