My question is, has anyone done or knows of anyone who have done an astronomical simulation of how this could have happen? Alternatively does anyone knows or have access to any simulation facilities for me to attempt such a simulation myself?

    If everything astronomical - and I do mean everything - stopped moving for, say 12 hours, there would be no trace of it astronomically. Men would experience it but there would be nothing left, afterwards, to measure or document. – Nigel J Apr 26 '18 at 13:03

    @Nigel You never know... Do things get serious whiplash or retain their momentum? :) Or did some animal that hunts at night starve for lack of prey? Maybe we can find its fossil... Anyway, the solutions to such problems would obviously be as miraculous as the event itself, and as I think the consensus is, trying to find a way to fit miracles into natural law seems pretty self-defeating. – Luke Sawczak Apr 27 '18 at 12:31

    It was already worked out in 1890. – Dɑvïd Apr 28 '18 at 20:20

The short answer is that, no, despite a persistent urban legend that NASA modeled this on one of their early computer systems, the reality is that such a simulation is impossible. According to Dr. Danny Faulkner writing for Answers in Genesis

From time to time, one hears that NASA computers have proved the account of the unusual day that accompanied the Battle of Gibeon found in Joshua 10:12–14. This marvelous little story about NASA computers began circulating in the late 1960s and early 1970s, during the heyday of the Apollo program. According to the story, in preparation for the Apollo moon landings, a computer at NASA calculated the positions of the earth, moon, and other solar system bodies with great precision far into the past and future.

This computer program produced a glitch in the fifteenth century BC, a glitch caused by solar system bodies not being in their correct positions, indicating that nearly a day was missing from time. An additional 40 minutes also was missing several centuries later, so that the total missing time was one full day.

Supposedly, NASA scientists and engineers puzzled over this problem until one of them opened the Bible to Joshua 10:12–14 and 2 Kings 20:8–11. The NASA personnel supposedly came to realize that their missing day could be explained by addition of nearly a day at the time of Joshua and an additional 40 minutes at the time of Hezekiah, thus proving that these biblical events actually occurred.

This story was carried in a few newspapers at the time, but it enjoyed widespread circulation among Christian audiences in the United States.

Dr. Faulkner then goes on the detail the origin of the false claim:

The person who appears to be responsible for this story is Harold Hill, president of the Curtis Engine Company in the late 1960s. Hill told the story a number of times before finally committing it to print in a 1974 book, How to Live Like a King’s Kid. Hill’s company had done contract work for NASA during the Apollo program, and Hill claimed that during this time he became aware of the computer confirmation of Joshua’s long day through his work at NASA. In some versions of the story, Hill worked for NASA, but Hill never did. Furthermore, the sort of work that Hill’s company did would not have placed him in a position to be privy to this sort of information. Hill claimed to have seen documentation of this supposed event as a NASA memo, but Hill could not produce the memo. Some people have speculated that if Hill actually did see such a memo, the memo may have been an April Fool’s Day prank.

The problem with this story is that a computer could not find such a discrepancy in the positions of solar system bodies. In order for a discrepancy to be found, we must know exactly where things were at some time in the past prior to Joshua’s long day, so that the calculated positions can be compared. A computer can calculate only where things ought to have been in the past; it cannot compute where things actually were in order to make a comparison.

So, in short, in order to be able to model such a scenario, we would need four points of measurement and two measurements:

  • The current time
  • The present position of orbital bodies
  • An exact time measurement before the events recorded in Joshua
  • The position of orbital bodies before Joshua

These measurements would allow us to calculate the exact amount of time that elapsed. We could then model where the planetary bodies should have been historically if orbits had stopped by simulating the orbits backwards in time to the timestamp before Joshua's events. But then we would need a point of comparison - Eg, does the calculated positions match the known positions before Joshua's event, or is it off by 24:40?

Unfortunately, we lack the data of two key things:

  • An exact timestamp of the events of Joshua (it is not enough to know the approximate year(s) or even months) and even if this were determined we would still need
  • The exact orbital positions of planetary bodies before Joshua.

So this is a simulation that will never be able to happen.

Note: This analysis is also supported by Dr. Tommy Mitchell and several other scientists

  • I think however a simulation could still be done. We suspend the questions of how did the sun attained its acceleration to start moving etc. and make some assumptions of the planetary positions. The simulation's objective is to see what effects of this motion on the planets eg planets get ejected, orbital eccentricity changed, earth's revolution, and rotation changed, etc. We can simulate this for a range of initial planetary positions. – Enoch Apr 28 '18 at 10:59
  • @Enoch, Technically speaking, yes a simulation would be possible with the necessary input data. The problem arises in make some assumptions of the planetary positions. we just don't have precise measurements of planetary positions at a specific timestamp on which to base those assumptions. We can find some general positions at general times based of historical texts, but these just aren't precise enough to find a missing 24:40. We just don't know initial planetary positions. The issue isn't our ability to simulate and extrapolate the physics involved, it's with the input data. – James Shewey Apr 28 '18 at 18:32
  • OK, so it could be done. Then the question is: was this possibility ever taken up? As to the input conditions, we just run the simulation over the entire possible period say, +/- 100 years. Not a problem with super computers these days, I would think. – Enoch Apr 29 '18 at 5:17

    You misunderstand - these calculations by supercomputers would be incredibly precise and the input and output must/would be as well. There is no +/- 100 years. There is no +/- 1 hour. Otherwise your margin for error exceeds the 24 hours of Joshua and the 40 min of 2 Kings. Your fault tolerance on the exactitude of the input data is, on the order of +/- 1 minute. This obviously requires measuring equipment that simply was not available before the time of Joshua. If your input has a margin of error of +/- 100 years, the output will have at least that much margin for error (and maybe more). – James Shewey Apr 29 '18 at 7:39
