We should expect that there are many galaxies similar to ours. So when we observe a spiral galaxy far away we should expect to see stars with the same range of colors. This isn't the case. All stars appear "redder" than they should be. This increases as the galaxy is farther and farther away. This is just a Doppler effect occurring on the electromagnetic spectrum of the galaxy being observed. In general, galaxies are racing away from us. Something is pulling them and gives them a greater velocity than any other random velocity they may have.
This means the universe expands. When you expand a gas it gets cooler. This means that in the past the universe was smaller and had a higher temperature.
When you have higher temperatures the particles have greater energies and the kind of "calm" system we're so accustomed to breaks down.
At a temperature of about 3000°C the electrons in hydrogen reach high enough energies/velocities that they leave the atoms. So the early universe had no atoms in it. Only electrons and bare nuclei zipping around, unable to catch each other.
From watching those neon store signs it's easy to imagine what happens when a gas has it's electrons stripped out: The gas glows and you're unable to see behind it. It has become opaque. So this means that this early universe had an "orange glow" (characteristic of ionized) and photon couldn't travel very far before being absorbed by the fog. This means that if you were there you wouldn't be able to see very far.
In a sense I'm trying to explain that high temperature/high energies make our physical laws go whack. Our work is to "correct" the formulas we have to account to these extreme circumstances that were common before our time. And light from very far far away gives us a glimpse of that.
Maybe this somehow answers your question.
