A null result would suggest that humans might be alone in the galaxy or the universe.
Should no detection be made, a null result would still be very significant.
In carefully designed scientific experiments, even null results can be evidence of absence.
The next figure shows what empirical tests of this hypothesis have found: a null result.
However, his experiments were duplicated many times, always with a null result.
However, the null result indicated something was wrong with the concept.
Indeed, the null result in this case is the most interesting.
Baker must have thought that meant a null result.
But he had blown his cover by announcing the null result far too early.
But everyone involved had indicated they learned something in the process of generating the null result, and the detectors continued to run.
