Star Births? Stellar Evolution? 2
If stars evolve, star births would about equal star deaths. Within our
Milky Way Galaxy alone, about one star dies each year and becomes an
expanding cloud of gas and dust (b). Deaths of more massive stars are
much brighter, more violent explosions called supernovas. Star births,
on the other hand, would appear as new starlight not present on the
many photographic plates made decades earlier. Instruments which could
detect dust falling into and forming supposedly new stars have not
done so. (c). Actually, stars that some astronomers believe are very
new are expelling matter. We have seen hundreds of stars die, but we
have never seen a star born. (d).
b. These explosions were misnamed "planetary nebula," because early
astronomers with evolutionary ideas thought these clouds were forming
planets around new stars. [See Bruce Balick and Adam Frank, "The
Extraordinary Deaths of Ordinary Stars," Scientific American, Vol.
291, July 2004, pp. 50-59.]
"Herschel ... speculated they might be planetary systems taking shape
around young stars. The name stuck even though the opposite turned out
to be true; this type of nebula consists of gas molted from dying
stars. ... [Planetary nebula] pose challenges to stellar evolution
theory, the physics that describes the life story of stars." Ibid.,
p. 52.
c. "... no one has unambiguously observed material falling onto an
embryonic star, which should be happening if the star is truly still
forming. And no one has caught a molecular cloud in the act of
collapsing." Ivars Peterson, "The Winds of Starbirth," Science News,
Vol. 137, 30 June 1990, p. 409.
"Precisely how a section of an interstellar cloud collapses
gravitationally into a star-a double or multiple star, or a solar
system-is still a challenging theoretical problem. ... Astronomers
have yet to find an interstellar cloud in the actual process of
collapse." Fred L. Whipple, The Mystery of Comets (Washington, D.C.:
Smithsonian Institution Press, 1985), pp. 211-212, 213.
d. "The origin of stars represents one of the most fundamental
unsolved problems of contemporary astrophysics." Charles J. Lada and
Frank H. Shu, "The Formation of Sunlike Stars," Science, Vol. 248, 4
May 1990, p. 564.
"Most disturbing, however, is the fact that, despite numerous
efforts, we have yet to directly observe the process of stellar
formation. We have not yet been able to unambiguously detect the
collapse of a molecular cloud core or the infall of circumstellar
material onto an embryonic star. Until such an observation is made, it
would probably be prudent to regard our current hypotheses and
theoretical scenarios with some degree of suspicion." Ibid., p. 572.

Unscientific and Hopelessly Inadequate
