Rise and fall 2: Rise and fall of the cosmos

Talking of 'rise and fall', we usually imagine such comparatively short-lived ones as 'civilization = hundreds to thousands year spans' or 'dynasties = tens to hundreds year spans', however is there rise and fall in such longer-lived ones as 'the cosmos = tens of billions year spans', 'the earth = billions year spans' or 'the human race = millions year spans'?

Some 'shake' happened in the pre-cosmos which had been in a chaotically balanced condition, the pre-cosmos lost its balance, and the imbalance of gravitation occurred. The pre-cosmos began contracting all at once and a big explosion came about in a flash when the pre-cosmos condensed into a size of the point of a needle, not as simile. The cosmos born by the big explosion, after that event, has been expanding through producing atoms, stars and lives for tens of billions of years; the above is the 'Big Bang Cosmology' which has been a core of the contemporary cosmology.

 

The above hypothesis is not one we can easily believe in, even I think it is rather cook-and-bull a story. However, it can be the most effective theory to explain the present condition of the cosmos. It is not yet confirmed whether the theory is ultimately accurate, hence some leading electro-magnetic physicists have published a very interesting book titled 'THE BIG BANG NEVER HAPPENED'.

Immediately after the Big Bang, in less than some 10-9 seconds, it is presumed that most of light atoms which form the contemporary cosmos. During that short time, no more than a moment, the big event happened in which matter and antimatter collided with each other and disappeared as energy, it is presumed so.

If we call it 'matter' that forms the current cosmos i.e. elements which form stars or human bodies, the one which has completely opposite structure is called 'antimatter'. In the 'matter' negatively charged electrons turn round positively charged protons, however in the 'antimatter' positively charged electrons turn round negatively charged protons. If both of them meet, they draw one another and instantly become energy of light.

It is the world of that Einstein's super famous equation 'E=mc2' i.e. energy equals to an amount of matter's mass multiplied by squared light speed.

It is presumed that matter forming all of the present cosmos, it seems to us nothing but 'indefinite', is very few leavings which could be saved from the disappearance at that moment.

After the instantaneous grand opera, I am not sure if it could be called so, from the big bang to the big disappearance, occasionally nebulae collide each other, big stars, our sun is a medium star, extraordinarily explode into super novas at the time they finish their lives, new stars come into the cosmos everyday, comets such as Halley's comet, fly away skimming the sun or sunspots periodically increase or decrease at intervals of around ten years. It can be said that the cosmos has been spending 'uneventful' days from a viewpoint of the whole cosmic scale.

Therefore, we might be able to say that there is no rise and fall in the cosmos, however according to the today's cosmology, the span of cosmic life is around 50 billion years and the present is presumed to be almost at the turning point. So it is presumed that about 25 billion years the current cosmos will end its life. If so, as nobody knows what kind of dramas will be waiting for us, it can be said that rise and fall will happen from now on.

If the cosmos really has its life, we could think that the cosmos is one of our close friends which also die or decline. The attached photograph shows one of the 'super novas' which was discovered recently.
