Astronomy can only look back to when the universe was 380,000 years old and about 3000K because:
a. at the Big Bang the universe was too hot and dense for electromagnetic radiation to survive.
b. the temperature of the cosmic microwave background radiation was too smooth (isotropic)
c. the universe was full of ionized gas that was not yet transparent to light
d. when the strong force separated from the other forces, inflation caused space to increase in size rapidly.
e. photons were not produced until the era of recombination.

Also, I'm just curious, is it impossible to see beyond the cosmic light horizon because any light from beyond the horizon has not had time to travel all the way to us?

Thank yooou.
 
D

we can only see that far because that is how far the light has traveled to us.

If you can see in another way than using light I would like to be enlightened, no we cannot see past the horizon, but that horizon is expanding at the rate of one light year per year (OMG!!!).
