Can You See What It Is Yet?

So now we know what the 'oldest light' looked like. Kind of mottled. Apparently this image tells us that there's a bit more matter and a bit less 'dark energy' out there, that the Hubble Constant's slightly out, and that the universe is about 50 million years older than was previously thought, at 13.82 billion years. Happily this means that the Big Bang Theory theme song remains authoritative...
'Our whole universe was in a hot dense state,
Then nearly fourteen billion years ago expansion started. Wait...
The Earth began to cool,
The autotrophs began to drool,
Neanderthals developed tools,
We built a wall (we built the pyramids),
Math, science, history, unraveling the mysteries,
That all started with the big bang!'
That's enough science.
