Show you as in bring the samples from the moon over to your house? I can't do that but I can post a picture:
Shaping the Planets: Impact Cratering
Impact basins are very large impact structures that are more than 300 kilometers (185 miles) in diameter. The largest impact basin on the Moon is 2500 kilometers (1550 miles) in diameter and more than 12 kilometers (7 miles) deep. Large impact basins are also found on other planets, including Mars and Mercury.
The large circular dark areas in the image are impact basins, created as huge impactors struck the Moon. Lava later flowed across the low floors of the basins, giving them a darker, smoother appearance than the surrounding, brighter highlands. The dark basins can be seen by the naked eye.
The moon is filled with titanium ores – prospect for mining colony in the future
“Looking up at the Moon, its surface appears painted with shades of gray – at least to the human eye. But with the right instruments, the Moon can appear colorful,” said Robinson, a professor in ASU’s School of Earth and Space Exploration in the College of Liberal Arts and Sciences. “The maria appear reddish in some places and blue in others. Although subtle, these color variations tell us important things about the chemistry and evolution of the lunar surface. They indicate the titanium and iron abundance, as well as the maturity of a lunar soil.”
The moon, that giant lump of rock that has fascinated poets and scientists alike, may be about to get even more interesting. A new analysis of isotopes found in lunar minerals challenges the prevailing view of how Earth's nearest neighbor formed.
Previous research has established that the oxygen isotope composition of lunar samples is indistinguishable from that of Earth.
Moon Rock Analysis Casts Doubt on Lunar Origins
"I think the general idea of having an impact forming a disk and this disk then forming a moon is probably right," he says, "but this paper shows us that we still don't understand exactly what the mechanism is, and there is a lot of work to be done in that field."
The moon remains drier than any desert on Earth, but the water is said to exist on the moon in very small quantities. One ton of the top layer of the lunar surface would hold about 32 ounces of water, researchers said. ?
"The isotopes of oxygen that exist on the moon are the same as those that exist on Earth, so it was difficult if not impossible to tell the difference between water from the moon and water from Earth,"
Again, magma, or heat source, is the question. I would have to take their word on the time line.
One difference is that the Apollo 11 basalts contain much more of the element titanium than is usually found in basalts on Earth. The basalts found at the Apollo 11 landing site range in age from 3.6 to 3.9 billion years and were formed from at least two chemically different magma sources
It was NOT based upon observation, obviously. He did not "proclaim" the Earth to be hollow, either, he put it out as a theory. This was not Observational Science at all. Unless you can tell me I am wrong and cite what "observations" he might have made?
Newton’s Lunar Density Estimate
Three hundred years ago in 1692, an article by Edmond Halley proposed that the Earth was hollow.(1) Its theory was based on the value of lunar relative density given by Isaac Newton. The first edition of Newton’s Principia (1687) found that “... the mass of the Moon will be to the mass of the Earth as 1 to 26, approximately”, citing the relative densities of Moon to Earth as 9 to 5.(2) This value of lunar relative mass was in excess by a factor of three, as the true mass ratio is 1:81. Arguably the most significant error in the Principia’s Book III, it left an ultra-dense Moon circling our Earth.(3) Edmond Halley simply invoked these figures: “Sir Isaac Newton has demonstrated the Moon to be more solid than our Earth, as 9 to 5; why may we not then suppose four ninths of our globe to be cavity?”(4) It is remarkable that so erroneous a figure, having such unlikely implications, could be thus presented without need for further justification. Halley’s theory appeared as the first significant deduction to be drawn from the Principia.
Leonhard Euler was a Swiss mathematician and physicist. He has produced a large portion of modern mathematical terminology and notation, more specifically the notion of mathematical function. He is considered to be one the greatest mathematicians of all time, and has approximately one thousand publications (7).
Instead of Inner Earth consisting of concentric shells, Euler proposed that Earth was completely hollow(8)(9), with a six-hundred mile diameter sun in the center, similar to what Halley had proposed (central sun). The hollow interior he said, could be reached through holes at the North and South Poles, which if they exist today, are blocked from Google Earth, hidden and classified. Euler proposed that this central Sun provided life to the advanced civilizations that lived there.

When you explain to me how a 1500 mile diameter impactor can go threw the earth to impact the moon, and not leave a really big hole, Ill show you which dark spot stopped the earths rotation.
So im still waiting for your measurements and comparisons?
Opportunities for migration to the surface might be more plentiful in magma oceans which existed billions of years ago, compared to more recent basalts which did not come from magma oceans billions of years ago.
So, high-Ti magmas might form more easily than other mare basalts source regions, but their migration to the surface is more sluggish than lower Ti basalts.
So the moons titanium is too similar to Earths according to your source, so why are you making a big deal about the variation in basalt samples? This is logically inconsistent.
The proportion of 50Ti to 47Ti is another good indicator of whether a sample came from Earth, and, just as with oxygen, the researchers found the moon's proportion was effectively the same as Earth's and different from elsewhere in the solar system. Zhang explains that it's unlikely Earth could have exchanged titanium gas with the magma disk because titanium has a very high boiling point. "The oxygen isotopic composition would be very easily homogenized because oxygen is much more volatile, but we would but we would expect homogenizing titanium to be very difficult."
So a higher degree of vaporization than previous models presumed seems to solve the similarity problems. Still, I can't completely rule out that the impactor named "Theia" might have possibly had a similar composition itself though researchers consider this unlikely, but maybe not impossible. They would like to find a better explanation and perhaps they have found one.
In 2001, scientists began discovering that terrestrial and lunar rocks had a lot in common: the two bodies possess many of the same chemical isotopes. (Isotopes of an element have different numbers of neutrons from each other. These subvarieties are identified by different numbers; for example, potassium-39 or potassium-40). Isotopes can act as geologic fingerprints, because prior work has suggested that planetary bodies that formed in different parts of the solar system generally have different isotopic compositions.
These discoveries threw the giant-impact hypothesis into crisis because previous computer simulations of the collision predicted that 60 to 80 percent of the material that coalesced into the moon came from Theia rather than Earth. The likelihood that Theia happened to have virtually the same isotopic composition as Earth seemed extremely unlikely.
At first, scientists thought more precise isotopic analyses might help resolve this "isotopic crisis." However, more accurate measurements of oxygen isotopes reported in 2016 only helped confirm this problem, said study lead author Kun Wang, a geochemist now at Washington University in St. Louis...
Another model, proposed in 2015, suggests that a high-energy impact created the moon, one so violent that it vaporized Theia as well as most of Earth, including the young planet's mantle region (the layer just above the core). This dense vapor then formed an atmosphere that filled a space more than 500 times bigger than today's Earth. Much of this material would fall back onto the Earth as it cooled, but in addition, some of the debris formed the moon...
"I'm kind of surprised that the new model [proposed in 2015] fits the data the best," Wang said. Still, "we had no expectation which model we were going to support," he said.
The moon, being much smaller than Earth, cooled more quickly. Since the moon and Earth were tidally locked early on, the still-hot Earth — more than 4,530 degrees Fahrenheit (2,500 degrees Celsius) — would have cooked the near side of the moon, keeping it molten. On the other hand, the far side of the moon would have cooled, albeit slowly.
The difference in temperature between the moon's halves influenced the formation of its crust. The lunar crust possesses high concentrations of aluminum and calcium, elements that are very hard to vaporize.
"When rock vapor starts to cool, the very first elements that snow out are aluminum and calcium," study co-author Steinn Sigurdsson of Penn State said in a statement.
Aluminum and calcium would have more easily condensed in the atmosphere on the colder far side of the moon. Eventually, these elements combined with silicates in the mantle of the moon to form minerals known as plagioclase feldspars, making the crust of the far side about twice as thick as that of the near side.
"Earthshine, the heat of Earth soon after the giant impact, was a really important factor shaping the moon," Roy said.
When collisions from asteroids or comets blasted the moon's surface, they could punch through the near side's crust to generate maria. In contrast, impacts on the far side's thicker crust failed to penetrate deeply enough to cause lava to well up, instead leaving the far side of the moon leaving the far side of the moon with a surface of valleys, craters and highlands, but almost no maria.
If you are assuming all impacts are directly perpendicular to the surface, I can see why you might think this way, but in fact most impacts do not come straight down but occur at some angle relative to the surface. Here is the Earth and moon to scale today, where the Earth can hardly block any impactors from striking the moon due to the relatively small angular size of the Earth at its distance from the moon:

One of its chief attributes, is it high melting temperature. Even though it is found in lave, the amounts are minute. Titanium
Titanium chiefly is obtained from the minerals rutile, ilmenite and rarely from anatase (beta-titanium dioxide). Other titanium-bearing minerals include perovskite, sphene and titanite. These minerals resist weathering and are concentrated in placers and wind-blown sand deposits. Titanium is mined in Australia, Sierra Leone, South Africa, Russia and Japan. Ilmenite is a common mineral on the Moon. Any future settlements on the Moon would likely use titanium as a primary building material.
How Do We Know That It's a Rock From the Moon?
Some of the most common minerals at the surface of the Earth are rare or have never been found in lunar samples. These include quartz, calcite, magnetite, hematite, micas, amphiboles, and most sulfide minerals. Many terrestrial minerals contain water as part of their crystal structure. Micas and amphiboles are common examples. Hydrous (water containing) minerals have not been found on the Moon
Taken as a whole, the ratios are fairly similar. You're singling out some exceptionally high amounts as if they represent the moon when that's not the case. Most of the moon basalts do not have such high TiO2. Look at the graphical representation in the link I posted previously on lunar basalts. Only the green areas are higher than typically seen on Earth, the rest of the moon's basalts fall in a similar range to Earth's.

It is not the composition, the spectral differences, it is almost indistinguishable, the difference is, its 10 times the amount. If the moon came from Earth the ratios should be similar. they are not.
Yes there are exceptional regions but they constitute only a small fraction of the moon's surface thus don't represent the entire moon. The paper explores some possible mechanisms which might explain the variations seen but they don't presume the moon has a vastly different TiO2 content, because clearly such abundance is not reflected in the great majority of the lunar basalts.
FIG. 2. Galileo SSI nearside image (resolution 1-2 km) that shows only mare regions; all other geologic units have been masked. The TiOz distribution shown in the histogram (Fig. Ib) is apparent in the image; very low (7.5 wt% Ti02) maria constitute only 5% of the lunar maria.
So in other words, you're totally barking up the wrong tree with your claims that these variations reflect source composition. The variations instead reflect certain mechanisms described in both this article and the lunar basalt article.
neither Ti abundance nor Ti/Y ratios in basalts can reflect the nature of their mantle source. Moreover, the different types of mafic–ultramafic intrusions in the ELIP cannot simply be attributed to be genetically related special types of basalts, either high-Ti or low-Ti basalts. It is likely that they are merely the cumulus phases, i.e. chamber or conduit of the basaltic lavas.

Again, the moon is 2159 miles in diameter. Are you expecting me to believe the moon could withstand a impact of a 1500 mile wide rock??? Traveling at god knows what speed??? It would have been cut in half!!! This, is sheer Lunacy!!!

Flat Earth
This idea is gaining popularity with myraid number kooks and cranks. The earth is a globe and always has been. If you happen to fly a plane only with reference to the attitude indicator, the altitude increases as the earth surface backs away, indicating its curved.
Hollow Earth
It is harder to debunk. There is no proof whatsoever except some legends. It is were true can you imagine a 4200 miles of atmosphere above you at the centre. the atmospheric pressure there will be close to 300lbs/sqin. Now what kind of flesh and blood can survive there, certainly not the surface dwellers who are used to 15lbs/sqin of atmospheric pressure.
So if there are inhabitants in the hollow earth, they cannot survive on the outer surface. The trees in the hollow earth will be certainly huge
Yes, another way of looking at it. But I suspect, ONLY, those who emotionally try to control the thoughts of others.
We are the hollow earth inhabitants.
Oh, oh really, do share. I wonder what a nuke would look like going off on the moon...
The Oceanus Procellarum basin is about 1600 miles wide and is believed to have possibly been formed by impact (there are also non-impact theories for its origin).
Rectangular magnetic anomaly's? Hmmmm, base frame grid work??
It should be pointed out that data from the GRAIL mission seems to be pointing towards a non-impact origin for Oceanus Procellarum.

It's all very messy to be fair. Lyrans, Sirians, Orions.. then we have the Peladians, Nubirans, Zeta rectulans etc
Quite resonable to assume a significant influence to all from outside Sector 9.

OP says if you fly ONLY with the reference to the artificial horizon. try this on a really calm night
Yes the auto pilot will maintain altitude when altitude mode is on
I'm not a pilot, but I'm guessing if a pilot is manually keeping his altitude the same, he/she is constantly making micro-dips. That pilot may not notice making these micro dips because it is all part of the constant manual input needed to keep the altimeter reading a constant altitude.
