Can anyone tell me the reason behind spontaneous human-burning? Does it really occurs or its a hoax?

Question

You can find it in 'ABLAZE' by: Larry Arnold.
Men/women(mostly) are found burnt into ashes however things around them remain unburnt, even a paper 2 inches away.
e.g. A lady was found burnt into ashes on her chair however her news paper& the chair were alright. Her partially burnt bones were visible; temp. was very high; other things were alright.

Answer 1

I'll stick with (most of) the characters on CSI about this:
It just doesn't happen (although, for some reason, it's seems to be a rather popular legend.) See links below.
Here's an excerpt from the 2nd link:
"Today, there are several theories. One of the most popular proposes that the fire is sparked when methane (a flammable gas produced when plants decompose) builds up in the intestines and is ignited by enzymes (proteins in the body that act as catalysts to induce and speed up chemical reactions). Yet most victims of spontaneous human combustion suffer greater damage to the outside of their body than to their internal organs, which seems to go against this theory.

Other theories speculate that the fire begins as a result of a buildup of static electricity inside the body or from an external geomagnetic force exerted on the body. A self-proclaimed expert on spontaneous human combustion, Larry Arnold, has suggested that the phenomenon is the work of a new subatomic particle called a pyroton, which he says interacts with cells to create a mini explosion. But no scientific evidence proves the existence of this particle.

As of March 2005, no one has offered scientific proof of a theory explaining spontaneous human combustion. If humans can't spontaneously combust, then what is the explanation for the stories and pictures of people who have seemingly burned from within?

If spontaneous human combustion isn't real, then what really occurred in the many pictures that exist of the charred bodies? A possible explanation is the wick effect, which proposes that the body, when lit by a cigarette, smoldering ember or other heat source, acts much like an inside-out candle.
A candle is composed of a wick on the inside surrounded by a wax made of flammable fatty acids. The wax ignites the wick and keeps it burning. In the human body, the body fat acts as the flammable substance, and the victim's clothing or hair acts as the wick. As the fat melts from the heat, it soaks into the clothing and acts as a wax-like substance to keep the wick burning slowly. Scientists say this is why victims' bodies are destroyed yet their surroundings are barely burned.
And what about the images of a burned body with feet or hands left intact? The answer to that question may have something to do with the temperature gradient -- the idea that the top of a seated person is hotter than the bottom. This is basically the same phenomenon that occurs when you hold a match with the flame at the bottom. The flame will often go out without provocation because the bottom of the match is cooler than the top.

Finally, how does science account for the greasy stains left on walls and ceilings after a "spontaneous combustion"? They could simply be the residue that was produced when the victims' fatty tissue burned.

No one has ever conclusively proven or disproven the truth of spontaneous human combustion, but most scientists say that there are more likely explanations for the charred remains. Many of the so-called victims of spontaneous human combustion were smokers who were later discovered to have died by falling asleep with a lit cigarette, cigar or pipe. A number of them were believed to have been under the influence of alcohol or to have suffered from a movement-restricting disease that prevented them from moving quickly enough to escape the fire. Another possibility is that some of the fires and strange states of the victims' bodies were the result of a criminal act and subsequent cover-up."

Answer 2

Human bodies are some 70% water, not napalm. How could they burn?

Have any farm animals or pets been found to combust?

How often do you hear about this?

Is it ever reported on news media?

Do YOU know of any instance, aside from some bizarre reading material? Did you know any peron who died this way, and people at the funeral discussed it?

Lightning or electrical charge might account for burning. So might cigarettes, with certain types of clothing. But that would not be SPONTANEOUS, now would it?

NO fire starts spontaneously. They require combustible material, oxygen, and sufficient heat to cause the rapid oxidation process.

HOAX.

Answer 3

It hasn't been proven or disproven as far as I know. But the main thoughts as to how it happens is the 'Wick effect' which is basically the burning of fat. The wick effect has been proven as being real but that doesn't mean that it is the reasoning behind human combustion or that human combustion is real.

Answer 4

don't be daft. The very theory that human beings can in basic terms unexpectedly develop into invisible is preposterous, and breaks very almost each and every thing of physics. Which e book did you examine that in? It develop into of direction not written by employing a acceptable scientist.
