Incredible, modern scientists - primarily the Brits and Americans are
propagating the anthropocentrically idea that white dwarfs are natural
phenomena. PULSARS are NOT NATURAL phenomena. They're possibly advanced
civilization navigation beacons much like a lighthouse is to a ship on
the ocean (see earthlings). These scientist are fools to think that the
laws of gravity and electromagnetics are the same at vast
distances.

"A pulsar is a type of neutron star, a collapsed core of an extremely
massive star that exploded in a supernova. Whereas white dwarfs have
incredibly high densities by earthly standards, neutron stars are even
denser, cramming roughly 1.3 solar masses into a city-sized sphere.
Pulsars give off radio and X-ray pulsations in lighthouse-like beams."

Pulsars are possibly virtual extraterrestrial lighthouses that can't be
decoded with humanity's digital signal processing and it thwarts the
paradigm. Read "Decoding the Message of the Pulsars"
 by Paul A. LaViolette, Ph.D.
One of LaViolettes premises is the mathematical placement of the pulsars
to the center of the Milky Way Galaxy - most are a perfect radian from
the center of the Milky Way.
The power's that be do not want a younger generation to harbor
the idea because it would throw a monkey wrench into their archaic
paradigm.

Utter Bunk!
When first discovered that was one idea but scientists soon learned they
were entirely natural phenomena.
