Let's Start A fresh!! What about the event of life starting on the moon, confuses you. Simply the gravity of the earth is greater than the moon, this defines that a smaller life form one less than two pound could have formed on the moon,prior to life on earth. Is not the moon in the so called life Zone of our solar system. Sure enough it would seem rather odd to say life started on the moon with out some exsplaination, and so, as it appears the earth was once much larger than it is today, assumably it was as large as jupiter its self, of which the moon may have taken its orginal formation, given the assement of soil samples ectra that are declared the same age and near compostion as earth. it would only follow to reason that the moon was within the physical enviroment of the larger past earth, assuming that such a prior earth body was mostly gaseous, simply the moon would float in such a enviroment of atmosphere. considering a density of 1 or higher as that of jupiter. life in such a case could there for exist on the moon, and in earths case orginate from there, in calculation i found a seperation of the moon from the earth atmosphere at about 10,000 miles, Earth radius 10,000 miles, this event would have occured some 248,000 years ago, where the earths terristal density was about 2.8. Given the gravity of earth being higher it is more lilky that earth would premote life on the moon before the moon premote life on the earth, thats simple logic. DwayneD.L.Rabon
It wasn't, of course. That's just more of his rambling nonsense. Not long ago, I read on NASA's website (and I've seen it in other places as well) that the Earth actually gains mass every single day from the space debris that rains down on us. In other words, it's NEVER been larger than it is right now - and it will be slightly bigger tomorrow. Please Register or Log in to view the hidden image!
I was wondering if only Americans had been on the moon. I read that the Russians made several hard landings and soft landings. What's the difference?
Hard landings are a euphemism for crash landings. The earliest Moon probes, like the Ranger series, simply kept transmitting pictures until they impacted on the surface. The technology to decelerate in a vacuum, and land intact, either didn't exist or was uneconomical at the time. Soft landings, of course, were essential in the Lunokhod and Apollo programs. Writers used to assume that the Moon originally had an atmosphere and hydrosphere, which were lost to space due to its low escape velocity - in that case, life could perhaps have got started there, including vegetation (and might still exist, in some unimaginably hardy and insulated form, perhaps tapping underground pockets of gas and water...) However, rock samples returned from the Moon show virtually no volatiles, including water. If the current theory of Lunar formation via a giant protoplanetary collision with Earth is correct, then very little water or gases would have been incorporated into the yong Moon - such light compounds would have simply dispersed in space, not accreted. Our poor Moon was probably airless, waterless and lifeless right from the start. :bawl:
The Moon acts as a precise measurement of the truths of astrology. I dont think I need to say more because they are well documented.Please Register or Log in to view the hidden image!
Temur is correct in his last post. We will not loose the moon. But it's orbit will stabilize and we will loose our tides and our rotation. But by that time, the Earth will unhabitabal as the sun will have expanded and gotten hotter, making life on Earth rather uncomfortable.
Is the moon shaped like a pear? Seems like with one side always facing us, that side we pull on would get pulled out a bit.
You know, I think Orleander is a very smart lass and she knows well how much of a slave we men are to testostrone.
I don't know. OK, our moon doesn't spin on its own axis because the gravitational pull of the earth is so strong, right? Why then would the moon develop into a sphere and not a pear shape? Wouldn't the gravitaional pull of the moon pull it more to one side....our side?
First of all, the Moon does spin on its own axis, At a rate of 1 rotation per orbit around the Earth. (This leads tot he fact that the Moon does not keep the exact same face pointing towards the Earth at all times. The Moon's orbit is slightly eccentric, meaning that it changes distance from the Earth during its orbit. When it it nearer the Earth it orbits slighty faster than when it is further. OTOH, the Moons rate of spin is constant. So at times the spin lags behind the orbit and at time it speeds ahead. From Earth this makes the Moon appear to rock back and forth on its axis and brings a part of the "farside" of the moon into view over the course of a orbit. This rocking back and forth is called "Libration". Any shape the Moon finally settled on happened when it was younger and hadn't solidified yet. The Moon does have bulge, but it is on the farside, and apparently formed when the Moon was "softer" and had a more eccentric orbit. The Moon did not always rotate with the same period as it orbited as it does now. Some models show that this bulge could have formed during a time when it rotated at a rate of three rotations per 2 orbits.
