How come we measured the radiation from the Big Bang?
I can’t get my head around how we measured the radiation from the Big Bang in order to discover how old the universe really is. How does that specific radiation differ from many other types of radiation? Newest findings suggest that the age of the universe has been mistaken not because of an error in calculations, but because of some kind of error in the understanding of the nature of cosmos itself. While I will probably not think up anything remotely usefull to anybody, I’d like to understand this part – please help a humble redditor.
