Are you for real?
a) the 'second' that you are talking about is a man-made unit of time. To think that an alien being (or scientific group of alien beings) would know that we slice our day into 24 hours, that each hour is sliced into 60 minutes and each minute into 60 seconds staggers the imagination. (If the otherworld entities had three fingers on each appendage they'd probably be counting in base 6. Ever think of that? Unless they had three appendages -- then they'd be counting in base 9.)
b) IF (really big if here, folks) the divide by 24/divide by 60/divide by 60 rule was figured out, how in hell could any living being control a pulsar? Do you know what a pulsar is? It's not a small car.
c) IF IF IF (into the zero probability IF now) the divide by thing was figured out AND control of a pulsar managed, wouldn't they get it dead on? No variation?
Sheesh. Some people will believe anything.
