What's the matter with Mercury?

What's the matter with Mercury?
An Astronomer wrote the following at the Sky and Telescope:
http://www.skyandtelescope.com/news/home/13802707.html
"What amazed me then, as now, is:
• How Mercury looks superficially so like the Moon — they both have scads of craters, giant impact basins, and broad lava plains — and yet are so very different.
• Scientists estimate that Mercury's metallic core takes up 75% of its radius and nearly half its volume. How, this "iron planet" came to exist, remains one of the great mysteries of planetary science.
• What's the source of the tenuous atmosphere that envelops it? And are there really deposits of ice at its poles?
• Something happened at the dawn of solar-system history that set this innermost planet distinctly apart from its terrestrial siblings."
---------------------------------------------------------------
I say:
The ambiguity and various strange observations about Mercury may be explained by the fact that Mercury has stopped its axial rotation, and it does only orbit around the sun with one hemisphere always facing the sun.

Mercury has stopped its axial rotation, a long time ago, (and was followed by Venus which later on has also stopped its axial rotation). Now both Mercury and Venus do not spin around their axes, but the two still orbit the Sun.

This was because of the depletion of their central heat, by time, because of volcanoes and heat radiation. The next turn will be for the Earth to stop its axial rotation, when its central heat will decrease then finish.

When the planet stops its axial rotation, it will have one of its hemispheres facing the sun; this side will have a lasting or continuous daylight; the other side will have a lasting night darkness.

The day-side will have accumulation of heat that will reach hundreds of degrees, and the night-side will have extreme coldness and freezing that will lead to the extermination of life that once existed on both Mercury and Venus.

Moreover, the core of the planet has already become cold, and its core density then will increase.

The surface of both Mercury and Venus (like our Moon) will be vulnerable to the falling down of comets upon them (particularly on the frozen side), and which will lead to the numerous craters that are ubiquitous there. Comets, when falling, will leave craters, but comets themselves will dig and bury under the ground; so that no remarkable rocks will be found in the craters.

The atmosphere of the planet, that has stopped its axial rotation, will undergo many changes: like the smoke and turbidity of its atmosphere; because of the mixing up of the gaseous constituents of the layers of its atmosphere. In addition, its weakened gravity, will lead to the loss of considerable amount of its atmospheric gases.

Are you saying they are tidally locked?......that would be incorrect.
They both still have axial rotation albeit with lengthly solar days

[CanisMajorTom]

yes and I would have to agree with Gyro. What scientific book is your reference?

Well our friend here has already been corrected in strong terms on the very webpage he linked us to! :) But freedom of speech is important, and i will quote the reply to Eanassir by Jagadheep Pandian of Cornell University. :)

"Eanassir, please stop spreading misinformation. Mercury has NOT stopped rotating. Even an object like the Moon, which keeps the same face towards Earth has not stopped rotating.
In order for a body to keep one face towards another body, it has to rotate around its axis once per revolution. In other words, the orbital period and rotation period has to match.
In the case of Mercury, it is in a 3:2 resonance with the Sun i.e. it spins around itself thrice per two revolutions around the Sun. This was first discovered using radar observations. I will not comment on the other fallacies in your posts above."

Nuff said.

I am not intending to spread misinformation, but to let others observe some serious points which are in need of further study and research.

O.K. I go along with you:
Moon keeps the same face towards Earth; that is right.
Mercury about keeping the same face towards Sun?
In case it keeps (or about that) the result will be extreme heat on one side and extreme coldness in the other side. And this is the actual findings of this planet, as is the case with Venus.

See about the abnormal movement of Venus and this statement at this site:

"Venus always presents the same face toward Earth when the two planets [Venus and Earth] are at their closest approach"

This brings us to an important point: Why is this unusual or abnormal movement of Mercury and Venus?
And what makes a planet moves faster or slower?
Does the Earth now move in the same speed like in the past? Or is it getting slower by time?


Moreover, they have deleted my website link which includes many details, on the pretext that it is religious. Then how can I cite all the details that I have included there? What harm will it do to see and read it?
The science duty is to investigate and research, not to lock and close minds. See what is there: if it is good accept it and if not you are not obliged to agree about it.
Let not any preoccupied attitude and some background let you blind yourself and readers. This is the science and the scientific way of dealing with ideas and suggestions.

G'day Eannasir,

Your religious links were removed because they are not scientific references.

This is a scientific forum. If you want to quote website links to back-up your claims, then use links that take us to scientific websites where there is observational data from highly skilled and highly educated scientists. Not men that walked around the desert hundreds of years ago.

What's more is that you have posted this same argument on other scientific forums about the place. The repsonse on other fourms has been the same as it is here. We don't need to explain to you what it is you are doing.

By pretending to be here to discuss astronomy, when in actual fact you are here to promote the Quaran is not being straight up and honest with people. So you are having the opposite effect of what you want.

You are welcome to reply, but don't post links to anything religious.

Prophet Mohammed lived in Mecca near the desert, but not in the desert itself, like the nomadic Arabs.

The people of Moses wandered in the wilderness of Sinai for forty years; with them were Moses and Aaron who died during this bewildering, as were Joshua and Caleb.

Jesus Christ rode on his ass, and went about the villages and cities of Palestine.

The desert has a strong link with astronomers till nowadays; they went in trips to the desert and mountains to see the meteor shower and other astronomical manifestations.

Our website link includes many important subjects in Astronomy, some of which do not agree with some of the present astronomical education, which are worthy of study and research, although it may not suit some; because of many factors that are understandable.
Our site includes also many other subjects in many other fields like Geology e.g. the origin of mountains, Biology e.g. the origin of life, and other science disciplines with many arguments and proofs.

eanassir.

Who cares where he lived or what he said? I certainly don't. I live in a modern age and definitely don't want to see primitive beliefs pushed on here as a replacement for intelligent scientific observations.

[LJF]

Well in the way of astrology. I believe the primitves, especially in the desert, had a really wide wrange of knowlege. More that we'd think they have.

Sometimes i wish we could go back to those ignorant days.:smile: *looking away into the distance*

Astrology is some sort of divination or claiming the knowledge about the fore-future, which is exclusively God's knowledge, that none else may know.
Anyone claiming he knows the fore-future; he assigns himself an associate with God.

Was that a "typo" and did you really mean 'Astronomy'. I agree the early Mesopotamians were leading the field in observation circa BC.

If you did mean Astrology then perhaps this is is not the foruum to push it.

Early Mesopotamians were idolaters and worshipped the stars and believed in Astrology. Prophet Abraham who was an Iraqi lived at Ur; he is the father of a large number of prophets. He was before Judaism and Christianity; he was a monotheist: believing in One God alone; he broke up the idols of his people.

"Mariner 10 saw these big, big cliff-shaped faults that have been interpreted as indicating the planet contracted -- shrank" -- as it cooled, Solomon said.

"Another early highlight of the [MESSENGER]flyby are ridges geologists call lobate scarps: photo http://messenger.jhuapl.edu/gallery/sciencePhotos/image.php?page=1&gallery_id=2&image_id=128
These are fractures in Mercury's crust formed, perhaps, as a result of planetary shrinkage."

"The volume of Venus was two-thirds that of the Earth, but later it shrunk, so that its volume becomes somewhat smaller."

I hate locking threads but this one needs to be closed. Sorry. :frown:
