Actually I should say that there are a few more things quite sure: the first is the Arecibo message sent out by Sagan and Drake....I have the least doubt about that.....the second should be the decode done by Paul Vigay...even though I did not personally verify it but since it is open online for so many years, if there is obvious problem, others would have pointed it out.....the third is the death of Paul Vigay..........as for whether the crop circle is created by man or alien is not sure but might be only sure for US government who has the most powerful satellites over the eartch......
thanks.....so far the only two things for sure: the first is that the crop circles were there since it were reported by the local media when they were still there and a lot people went to see the circles.......the second thing for almost sure is that the high definition and high precision satellites monitoring by US and some other governments should have record of how those crop circles were formed since this is not like secrete UFO things.....it is big and open in the field.........
I would think the article posted by 二野的博客 might be even more interesting: http://blog.creaders.net/jjeta/user_blog_diary.php?did=107815
I never thought about the question why the moon looks the same size as sun to us earth beings......and after read his article I come to think about it and feel that it is really amazing and could not be explained as natural by science...........now if it is true that the history of moon is 20billion years as it is said in that article, then we literally come back to the book Genesis..........I think a lot people like me have already thought that the BIG BANG theory is consistent with Genesis in many aspects but we need to reexplain the creation of Moon and Sun.....but now, if what is said in that article is true, it seems the data is more consistent with what is said in Genesis that the Moon and Sun was created at the very beginning.........at least the VERY OPEN OBVIOUS FACT that the Moon looks the same size as Sun to us earthly being is very very UNNATURAL by scientific standards......
I actually go online collected some data about Moon and Earth...it is said that the mass of Moon is 1/81 of Earth...but the diameter of Moon=3476 km while the diameter of Earth=12756 km, which means if the average density of Moon is the same as Earth then the mass of Moon should be 1/49.43 of the mass of Earth.....therefore, 1/81 either implies a much lower density of Moon than Earth or might mean around 60% of the Moon body is hollow (which is what is claimed in that article).......it is said that US has brought back some rock from Moon but nowhere mentioning that the density of those rock is much lower than the average of Earth.......of course, we could not use single sample to judge the average density either....the following is something about the structure of Moon from wikipedia:
The Moon is a differentiated body: it has a geochemically distinct crust, mantle, and core. The Moon has a solid iron-rich inner core with a radius of 240 kilometers and a fluid outer core primarily made of liquid iron with a radius of roughly 300 kilometers. Around the core is a partially molten boundary layer with a radius of about 500 kilometers.[27] This structure is thought to have developed through the fractional crystallization of a global magma ocean shortly after the Moon's formation 4.5 billion years ago.[28] Crystallization of this magma ocean would have created a mafic mantle from the precipitation and sinking of the minerals olivine, clinopyroxene, and orthopyroxene; after about three-quarters of the magma ocean had crystallised, lower-density plagioclase minerals could form and float into a crust on top.[29] The final liquids to crystallise would have been initially sandwiched between the crust and mantle, with a high abundance of incompatible and heat-producing elements.[1] Consistent with this, geochemical mapping from orbit shows the crust is mostly anorthosite,[6] and moon rock samples of the flood lavas erupted on the surface from partial melting in the mantle confirm the mafic mantle composition, which is more iron rich than that of Earth.[1] Geophysical techniques suggest that the crust is on average ~50 km thick.[1]
The Moon is the second densest satellite in the Solar System after Io.[30] However, the inner core of the Moon is small, with a radius of about 350 km or less;[1] this is only ~20% the size of the Moon, in contrast to the ~50% of most other terrestrial bodies. Its composition is not well constrained, but it is probably metallic iron alloyed with a small amount of sulphur and nickel; analyses of the Moon's time-variable rotation indicate that it is at least partly molten.[31]
