(By the way; rainy weather today)
USES OF THE MOON
If there were no tides and tidal marshes
Filling and emptying, then what?
Would life have formed?
Isn’t the moon really a planet?
Yes, it’s orbit is everywhere concave to the sun
And is captured by the sun and not by the earth;
Together they are a double planet system
Whose center of gravity is still
Within the earth somewhere.
What about lunar cycles
And bio- or menstrual cycles,
Moon gods, honeymoons, romantic walks,
A base for space travel,
’To the moon, Alice’,
And lunatics?
The reading I referenced
Was making the hypothesis
That tides created by a Moon
Orbiting at 30,000 Km from Earth
Had been “critical” for violently mixing oceans.
(Tides were far more great with a
So near orbiting object)
This mixing, lasted for at least 1 billion years,
Eroded a large amount of material
From new born continents
And this material continuously
Mixed and mixed again
Was at the origin of the first life,
Half a billion years after Moon formation.
No Moon, no party ... at least no party for life.
If this would be true,
The Earth collision and Moon formation
Would be the main first engine of life
And the probability of such an astronomical event,
I think, is very low.
The coincidence of this low probability,
Combined with the “improbable hill” life climbed
In few billions of years,
With the Fermi paradox ... is well ... amazing.
If life is so improbable,
Compared to the number of possible stars,
So strictly related to an almost impossible “collision”,
No surprise we are not able to get any signal
From any nearby partner.
In the same reading I found the statement
That Earth’s rotational axes will start to oscillate
At that time and that may will end
With Earth rotational axes in the orbital plane.
But for these accidents,
Including the elimination of the dinosaurs
And the fusing of a ‘chimp’ chromosome,
We might not have been here ever,
But as we say there are
Many stars and planets.
Moon Children
The Earth would wobble like a dying top very soon,
Without the steadying influence of our lovely moon;
But, it’s slipping from our grasp an inch & a half a year.
The end’s not so near, but we’ll need a way out of here.
Yep. It is going away at a rate of 3.8 cm/sec
(Thanks to the Apollo mission for this data).
I’ve been reading that Moon will leave Earth orbit
When it will reach the average distance of 440,000 Km
So in about 1 billion year 40,000 Km/3.8 cm*year^-1
(current distance should be around 400,000 Km)
The Moon will feel more attraction
From Jupiter and will say goodbye to Earth.
