This is not really something brand new but rather physical evidence found of what had been predicted from theoretical work on the universe years ago.

This has not been peer reviewed yet so is just considered a 'proposal' so far but all indications are that it will stand up to peer reviews and moves physical evidence from fractions of a second after the universe started expanding.
What is often referred to as The Big Bang Theory.

Now the details and info about this is hard to grasp by those of us not studying that field but the video with this short article is worth watching.
A former colleague of a retired professor who was author of a paper predicting this goes to tell the professor about their findings.

A little technical language is all it takes to get a reaction from the professor and by the reaction from the professors wife she also understood what was said.

The video kind of chokes you up.
