Might fit the theory. You can not say with absolute certainty that all the Dyatlov Pass Incident EVIDENCE fits the NO2 theory except for the ravine injuries.
Yes i can. Maybe we have a different understanding of what "fit" means in this context.
Strictly speaking it's the NO2 + N2O theory, nitrogen dioxide and nitrous oxide can explain all the evidence wrt the DPI except for the ravine injuries.
Now about the ravine injuries....
One of the theories to explain them is as i have already discussed - ball lightning rollers. This would be a fit on two counts (1) it explains Ivanov's obsession with "fire orbs". (2) the source of these would be from the same electro magnetic processes that explain the NO2/N2O and which imo were photographed by Semyon.
But it occurs to me that there is another theory concerning nitrous oxide....
Nitrous oxide (N2O) is heavier than air and has a boiling point of -90C and is of course heavily intoxicating to the extent that you can lose control of your limbs.
Now if the gas is unaffected by the cold and is heavier than air and is being produced at the top of the hill, it follows that it will obey gravity and travel down the hill.
Q. And what is at the bottom of this particular hill?
A. The ravine....
Q. And where is there a concentration of bodies?
A. In the ravine....
So maybe there is a theory here. The heavier than air N2O gas would end up in the ravine and displace most/all of the air creating a much higher concentration. So anyone near it's edge could suffer sudden and complete loss of control and fall into the ravine. Maybe one after the other like lemmings going over a cliff... So the first to fall would be injured by the second, the third would injure the first and second etc. The argument against the "falling theory" has been that people instinctively would put their hands out to protect themselves and hence you would need to see appropriate injuries (broken hands/arms/legs) for the theory to hold but N2O allows us to consider them falling without that control, like unconscious dummies landing on top of each other. This helps explain why some pathologists consider the injury profile to be from more than one event. Semyon's exhumation discovered that the pathologist had missed a fractured shoulder blade and he must have been lying on his back when his chest was crushed?
So here's a narrative.
They decide to build a den in the ravine which results in the discovered work.They go for a walk maybe to collect more branches/twigs etc.Up to this point the N2O concentration has been minimal.Now it strengthens and displaces all the air in the ravine and at the side/edge.The group return through the forest perhaps walking closely in single file.
As they reach the ravine edge they suffer immediate loss of control and fall in landing on top of each other. It could be that they slide down a steep slope picking up speed and momentum before reaching the actual drop.
The first to fall suffer the worst injuries, the last to fall the least which could include "combat injuries". Rustem has a fractured skull and internal bleeding that will cause him to give up relatively soon. Nicolai's head has been pushed into the ice so hard one side of the skull has caved in.
Now the N2O clears as it continues flowing down the ravine under gravity.There are only three able bodied survivors, Zina, Igor and Rustem.They lay the dead and injured in a row to assist them and try and conserve heat. As members die clothing is moved to the living. This includes scavenging from the 2 Yuris.
It is decided that they must try and retrieve more clothing/blankets etc from the tent if the injured have any chance. Semyon is still conscious and attempting to make notes.Zina and Rustem start the uphill journey. However Rustem cannot handle it and lies down in the snow. Zina adjusts his cap and heads off. However she has been affected by the NO2 -> nitric acid reaction and her cardio vascular abilities are much reduced to the extent that she has to crawl to try and continue until the crawling comes to a halt and she succumbs to the cold.
Igor waits for their return which never happens. Eventually he makes his way back but he to is affected by the NO2 and hasn't the strength for the incline. The lack of cardio vascular ability of the "returning three" explains the close grouping, they are all found within 300 metres of each other. Presumably as the incline steepens.
So now the NO2/N2O theory explains all the DPI evidence, every single item....
