OP

Nerdhappy's graphic I linked to earlier contains:



Maybe we're right about the Big Bang, but maybe it was actually a lot further back than 13 billions years ago (hopefully we can still nail it at 13.2B?), or maybe in 10 years everything we think we know here will be completely different, or I don't know what the fuck I'm talking about,  which reminds me of Olber's Paradox:
Olbers' paradox is the argument that the darkness of the night sky conflicts with the assumption of an infinite and eternal static universe. It is one of the pieces of evidence for a non-static universe such as the current Big Bang model. The argument is also referred to as the "dark night sky paradox" The paradox states that at any angle from the Earth the sight line will end at the surface of a star. To understand this we compare it to standing in a forest of white trees. If at any point the vision of the observer ended at the surface of a tree, wouldn't the observer only see white? This contradicts the darkness of the night sky and leads many to wonder why we do not see only light from stars in the night sky

Time for Olber to eat crow.
