Question

The 'Little Green Men Standard Time' hypothesis for the repeating radio signals seen in 1968 was rejected partly because the repetition rate was ________.

1) Too fast
2) Too slow
3) Irregular
4) Not repetitive

Answer 1

2 is the correct answer, the original answer was slowing down but was changed to too slow

Answer 2

The 'Little Green Men' hypothesis for the radio signals was rejected because the signals were extremely regular, suggesting a natural cosmic source, now known as pulsars.

Step-by-step explanation:

The 'Little Green Men Standard Time' hypothesis for the repeating radio signals seen in 1968 was rejected partly because the repetition rate was extremely regular.

What Bell had discovered in the constellation of Vulpecula was a source of radio emissions with precise, regular pulses that arrived every 1.33728 seconds.

This regularity suggested a natural cosmic source rather than a signal from an intelligent civilization, and these sources were later identified as pulsars.
