The distance of the
Moon and the Earth's revolving slowdown is reason by the gravitational pull of
the two stars from the formation of the system.
The Moon and the Sun appear
eternal. And while this is true for permanence small sample of time is human
life on galactic time, is only apparent, because the Moon will end when we
emerge from the star, the Sun, end their lives.
Beyond this fateful end, which
could mean that humanity is no longer in the solar system, there are other
indicators that contradict the appearance of permanency, such as the continued
shift away from Moon on Earth. The Moon moves and moves away from about 4,500
million years ago, when at the time of formation of the solar system, a star
about the size of Mars collided against a newborn Earth. The impact produced a
huge disk of matter to coalesce by gravity formed the moon, orbiting at this
early stage, some 23,000 miles away.
The orbit of the Moon
The first million years
of the Moon must have been the cause of permanent cataclysms that primitive and
unhealthy Earth. Gigantic tidal gravity that would have occurred in the
bubbling lava seas would be real nightmares for a possible witness. However
Moon started away continuously and, in fact, now a distance away of 3.78
centimeters per year, at which point averages 385,000 kilometers. At this point
remember that the Moon is a unique satellite in the solar system, given the
size it is on your planet, Earth. The moon is very large and this is important
in the forming system with Earth, since the influence and interaction of
gravity of both stars is crucial to life on Earth, especially in the tilt of
its axis, because it produces a very stable and regular seasons. Is that if we
thought for a moment that was not the moon, the Earth would have a slowdown
that would become unstable, would become somewhat chaotic and all regions of
the Earth that today enjoy a predictable stability, would be subject to sudden
temperature changes. Human beings could adapt to these changes because through
technological advances has mitigated the effects of climate extremes, but not
the same thing happen with many animals and plants that need very large
biological terms to suit.
The remoteness of the
Moon
The call tidal bulge is
the effect that the Moon exerts on the Earth's water, but it is also the tidal
activity that produces the distance of the Moon. This huge amount of water in
the bulge occurs tidal its gravitational force exerted on the Moon, since that
is also influenced by the rotation of the earth, so that it produces an
advancement of the moon. The combined gravitational forces of the moon occur on
acceleration, which inevitably generates to stay away from the Earth, because a
universal phenomenon in physics called “centrifugal force ". The removal
rate is 3.78 inches per year and oddly enough, just simply multiply by millions
of years to calculate the distance to the Moon was and investigate how it
influenced and how it will influence their future away.
The length of the day
on Earth
The tidal bulge
terraqueous produces acceleration of the Moon, but the opposite is Earth
because its rotation slows down. This could be studied in the bands of ancient
corals, in which you can calculate how many days was a year in primitive times.
It is estimated that when the moon formed, days lasted just under five hours to
more than 4,000 million years later, at almost 24 hours today. Lengthening of
the days, which means slowing the Earth's rotation, continues to average,
approximately 19 hours each 4,500 million years. Hard to believe that by that
time the conditions of the Earth are the same, probably the Sun is
"aged" and is a red giant, which the Earth and the Moon would no
longer exist. At that time the man may have moved to another star system, where
living conditions and stability are enjoyed by other several hundred million
years, and so on until all the material in the galaxy and the universe is
consumed.
