I read some where recently that some new galaxies have been discovered , which means that cosmologists and other will have to change their previously accepted understanding of the universe
If i remember correctly the galaxies are older than when the universe is thought to have been created
No, theyare not older than the universe, they formed in the first 2 billion years of the universe. However finding them does mean that astronomers neet to think again about galaxy formation in the early (well relatively) life of the universe.
