Tomk80 said:Your putting the cart before the horse. We need to establish whether it was a single event, and we need dating to do this. Remember, the locations can be due to random events and the spread of the locations might have another explanation than being from a single event. So you need an independent measure. Dating is such an independent measure and gives a large discrepency with your 'theory'. So what you need to do is either:
a) show that the dating is incorrec or
The cluster of strikes proves a single event and that the dating is incorrect.
Tomk80 said:b) show that the results from the dating are dependent on them being the result of the same event.
Or realize that the dates given are incorrect.
Tomk80 said:But let's summarize the data once more. The data shows a large number of meteor craters in well-explored areas and a small number in areas that aren't well explored.
No, we can select a small well explored area like Europe

and see the same result.
Tomk80 said:From the site it is clear that satellite data can track down meteor craters, but that craters that haven't been confirmed by geologic markers (such as shocked quartz) are not listed.
Such geologic markers can only be obtained by traveling to the area and either drilling into the location or collect the material from the top (dependent on how buried the crater is). The site also gives a table on the craters, listing whether they were confirmed by drilling, open air sample collection or both.
In case of the site above about half of the strikes in the concentrated area have been drilled and half of the sites in the non concentrated areas have been drilled indicating equal attention.
Tomk80 said:The craters have been dated. By the best of our knowledge, the dating methods are independent from the impact event itself. The dating methods give widely varying dates for the different craters. So to the best of our knowledge, the strikes were millions of years apart and not part of a single event.
Either the meteor strikes are random or the dates are incorrect.
It is possible the meteor strikes are random because there is always a chance they just happened to fall as they did.
Of course the odds against it would be extremely high but at least your current theories would not have to be changed.
Tomk80 said:If the meteor craters were in fact the result of a single event, the pattern is strange. It shows a large number of impact craters in Western Europe and America, but no impact craters in the ocean between them. Although Western Europe and America show most crater, craters are found all over the word. So if they are part of a single event, the meteor rain has hit every part of earth. Assuming that the event was a single meteor rain from a single point in space, it had to have been going on for at least 24 hours. But somehow, in the six hours it takes the earth to turn from Northern America to Western Europe, no meteors hit the earth. Your model faces a lot of problems, even without going into the physics of it all (you do realize that you are in fact proposing an event which could only have resulted in a very fried Noah and arc).
This is easily answered.
What I will suggest here is by no means the only explanation to your question.
A large object approached Earth and was broken up as indicated by the multiple meteor strikes.
The object separated into several larger objects first due to the gravitational forces induced by the Earth.
The separation distance of the objects parts at the time of impact would be related to the rotational velocity of the original object differential trajectories created and the differential in orbit time.
Variation in trajectories during the entry orbit path would cause the objects to progress in an intersect orbit progressing around the Earth until encountering the atmosphere.
Further disintegration of the objects due to gravity or due to contact with the atmosphere would be expected to some extent.
The final impact pattern would produce a condition consistent with the data shown.
The condition could also be explained by several independent events, each with multiple strikes.
The determination if this is the case would depend on the expected pattern of a multiple orbit entry from a single source and how that pattern compares to the evidence.
It is highly unlikely that two separate events would impact the same area on the Earth due to the fact that separate events should be randomly placed on the Earths surface just as independent individual meteor strikes would.
If it is found that multiple trajectories from a single source mimics the distribution data well it would be hard to argue against a single event for all non-random strike patterns.
Two or more major events in such a short time span is highly unlikely.
If the events are separated by a long enough time erosion will deteriorate one set of strike records before another set are created preventing them from existing at a common point time.
Determinations of this sort would require a more in-depth investigation then I am willing to conduct at this time.
Tomk80 said:On the other hand, the craters might have been single events. The reason we have found so many in Nothern America and Western Europe, can then be explained by the fact that these regions are best explored. Australia is well-explored too, and also shows a large number of impact craters relative to the size of the land. Since only confirmed craters are listed on the site you gave, and exploration is necessary for a crater to be confirmed, the number of craters in an area would be dependent on it's accessability to exploration and this is indeed what we see. Furthermore, the geologically active sites will probably result in the destruction of craters. So we wouldn't expect many on these sites. The dating method, which is independent of the event, also shows that the meteor strikes cannot be dated to the same time period.
Given the above, the most likely explanation is that the impacts are indeed random and spread out over a large period of time and that the perceived pattern is caused by the possibility for exploration of the sites and the geological activity of these sites.
My example above proves your suggestion incorrect as Europe has both high and low meteor impact densitys are evident in similar areas of geological stability and access.
I understand your desire to maintain your faith in your presently accepted theory.
I would make the same attempt if I was on your side of the fence and this how it should be.
Good luck in your endeavor.
