As the story of the 'rise and fall of the cosmos' was interesting,
we want to read a sequel to that. Such impressions, not a few, were
sent to me by mail, I prefer receiving them by blog to by mail,
so I will briefly tell 'rise and fall of stars'.
Lyall Watson famous for his writings such as 'Lifetide' may say
that such demarcation itself as follows is problematic, however
if we focus on the material world except for the spiritual world,
the 'cosmos' is literally the 'whole world'. Usually we can see
a variety of interesting dramas when we see various 'rise and fall'
being repeated in that 'whole world'. When we directly see the 'whole
cosmos', which should be a background, it is difficult for us to
clearly demarcate between what is rising and what is falling, so
was the former story.
Talking of that point, as 'stars' exist in the 'cosmos', they can
show very clear-cut dramas of 'rise and fall'.
Interstellar gas, mostly consisting of hydrogen, floating in the cosmos
a) begins contracting by the 'sway of gravity', b) condenses over
some threshold, c) the pressure and temperature of the core part of
which reaches a level enough for triggering off nuclear fusion of
hydrogen, and d) hydrogen of which begins fusing their nuclei and
emitting intense heat and light. This is the 'birth of a star', in
other words, continuous explosions of 'hydrogen bombs'.
It is not impossible to define, so much simplified, that the 'rise
and fall of stars' is a drama of the activity of 'nuclear fusion',
but setting it aside, it is not so much simple like 'rise and fall
of life'. Stars also have various chains such as gravity or inner
pressure and show characteristic rise and fall of individual stars.
Making it simple a sequel of the 'nuclear fusion', it continues changing
its fuel from hydrogen, the lightest element, to helium and to heavier
elements step by step, and then finishes its tough 'chain reactions
of nuclear fusion' just before iron.
The 'latter half life of stars' from this point will change into completely
different directions depending upon sizes they have had from their
birth. Corpulent stars will become super novas or black holes, a little
bit fat stars will become super red giants or red giants, and muscular-type
stars, the sun is one of them, will become white dwarfs or pulsars.
As for those course of events, please read a kind of guidebook, however
it is something interesting we can nod to that corpulent stars emitting
instant and intense brilliance is short-lived, while muscular-type
stars emitting modest light is long-lived.
One of my best favorite songs is 'Strolling around stars' songwritten
and composed by Kenji Miyazawa, composed as well!, and the first lyrics
is 'Red eye of the scorpion, coil of the brilliant serpent. Blue eye
of the little dog, expanded wing of the eagle. The Orion sings loudly
and left dew and frost'. It is something in the point that he weaved
not only the beautiful arrangement of constellations but also the
rise and fall of stars. The 'red eye of the scorpion' is the last
days of the 'little bit fat star, well the 'red giant', and the 'blue
eye of the little dog' is the younger days of the 'corpulent star'.
By the way, most of stars finish their lives with a big explosion
at their ends. Please keep it in the corner of your sense that without
'heavier elements than iron' all of animal, plant or mineral, for
example, could not come into the world. All beings including humankind
and cockroach are the 'prince of stars' or the 'princess of stars',
therefore please do not go against by any account the 'cosmic conscience',
e.g. trying to use a 'cockroach catcher'.
