Have we measured or found evidence of a detectable origin point of the big bang? Based on reading the wiki page of the big bang, a simple question with a probably not a simple answer came to mind.

The statement on the wikipedia page was.


  Since Georges Lemaître first noted in 1927 that an expanding universe could be traced back in time to an originating single point, scientists have built on his idea of cosmic expansion.


My question is:  Have we measured or found evidence of a detectable origin point of the big bang?
There is no single origin point.

Before the big bang, the entire universe was contained in an extremely dense singularity - there was no "space" for the universe to expand into, the very fabric of spacetime was contained entirely in the singularity. There is no single "origin point" in the universe where the big bang took place where we'd see the entire universe receding from us. Rather, from any point in the universe we can see everything else receding. The big bang happened everywhere, since the whole universe, including space itself, came from that singularity.
