Yah you are probably gonna laugh at me now. "around 13.7 billion years is young???", but I mean... compared to the age of earth. If earth is about 4.54 bil. years old, then 13.7 billion doesn't sound much... It feels like earth must be one of the very few (or only?) lucky planets to develop life so "fast". I thought it would take billions of years for the galaxies, solar systems... and our sun to form etc.
Is this "13.7 billion" (in the light of new research take or give 2 bil years) somehow a way longer period of time in space because AFAIK time functions in some crazy ways in space? I haven't studied much of physics, so I would be glad if some of you science nerds you could explain this a bit more.
