(This is not a HHGTTG question)

(1) and (2) were messing around with (3). While doing so, they detected something that they totally could not explain. They tried a lot to eliminate it (at one point of time, they even suspected (4)), but they just couldn’t get rid of it.

Eventually, they realized that they just couldn’t eliminate it because it was not an anomaly. It was real, and it validated decades of work, and basically proved one of the most debated hypotheses of all time, beyond any doubt.

What is it (that they discovered)?

And who are (1) and (2)?
