    Yeah, I'd love to find out a way to mathematically being able to calculate how much Oxygen that gets consumed in one minute from a massive fire.

    This is what i'd love to know:

    O2 + Fire (1 minute) + Area (Area: As large as the Earth.) = (Consumption of Oxygen for 1 minute.)

    Wouldn't it depend on the fuel?

    Alright, i'm gonna have to reveal it I guess. I am going to use facts to disprove "Hell".
    Since "Hell" consists mostly of Fire, the Fire must receive energy from something, I am going to assume that the fires in "Hell" came from a natural cause, like.. a lightning bolt or something like that, or simply just heat. So, no chemical substance like kerosene or gasoline or anything like that. So, what I need to know is how fast fire consumes oxygen, since fire can't live without oxygen, all I need to do is to prove that the fire already has consumed all oxygen and in such way, the fire is out and there simply is no such place full of fire. "Hell" is also said to be underground, so that reduces the amount of oxygen drastically.

    Any help is appreciated.

    Very ambitious! Ok well first of all I think you need to understand that there are probably hundreds of definitions of "Hell" and not all of them envisage an underground world composed mostly of fire, like in cartoons. Clearly though it's not necessary for people to share your beliefs in order to help you out with this question.

    I mean no offense whatsoever when I say that if it's possible to believe in Hell doesn't it follow that the fire doesn't have to be able to be explained by science? That's the argument that you're up against if trying to disprove Hell...

    I am going to assume that the fires in "Hell" came from a natural cause, like.. a lightning bolt or something like that, or simply just heat. So, no chemical substance like kerosene or gasoline or anything like that.
    Regardless of where the "spark" came from a fire still needs fuel, oxygen and heat to exist, if one is missing the fire can not sustain itself.

    I am going to debunk the Christian "Hell". If it is just one kind of Hell, that's okay, at least one kind can then be proven false and a new one has to be invented.

    Hm, so "what the Hell" can possibly be the fuel to the fire? Got any suggestions yourself? :wink:

    I'm pretty sure that a student somehow proved that there was no hell. I forgot the link, though.
    We hold these truths to be self evident, that all men are created equal, that they are endowed by their Creator with certain unalienable rights, that among these are life, liberty and the pursuit of happiness.

    Argh, typical. If anybody have an idea about fuel for fire, in Hell, or if no fuel can be thought up about, then it just makes it so much easier since if there is no fuel.. no fire. I'll look around a bit more on the net.

    Alright, if someone wants to help me with figuring this out, i'd be very thankful.

    O<sub>2</sub> + CO<sub>2</sub> + Heat (~1300-2000<sup>o</sup>C) + Area = O<sub>2</sub> consumption for 1 minute?

    The Earth's core is pretty damn hot, but not strictly fire... lol. Any rational person knows that there's no physical hell, like most religious stories it's just a metaphor. You're no more likely to find hell by burying into the earth than you are of finding heaven by looking around in the stratosphere.

    That is a rational statement which illustrates the impossible task you have set yourself.

    If a person believes in Hell he is not interested in rational arguments. Hell does not have to adhere to any laws of nature that exist, so fire without fuel is perfectly reasonable in Hell.

    This doesn't belong in Chemistry, by the way.

    How about radiation burns? The chronic symptoms of Hell sufferers - extreme thirst, burning agony, red skin (Satan) - match those in Hiroshima and Nagasaki. This is "fire" radiated from the initial atomic burst, before the fireball. No extra oxygen necessary there. And isn't Hell supposed to be dark, yet burning? Sounds like ultraviolet or infra-red to me.

    See, science may not disprove Hell but I think it can show the Christian that nuclear weapons are Satanic.

    Hahaha! That made me laugh Pong. ^^

    Anyway, I decided to atleast TRY to do the impossible, this is what I have right now:

    ..First, a bit of explanation:
    m<sup>^2</sup> = Squaremeter.
    O<sub>2</sub> = Oxygen.

    Short explanation of mathematical setup:
    10<sup>^-20</sup> = 000,000,000,000,000,000,001
    10<sup>^-2</sup> = 0,01
    10<sup>^-1</sup> = 0,1
    10<sup>^0</sup> = 1
    10<sup>^1</sup> = 10
    10<sup>^2</sup> = 100
    10<sup>^20</sup> = 100,000,000,000,000,000,000

    Area of a sphere = 4 x Pi x Radius<sup>^2</sup>, Radius<sup>^2</sup> means squareradius.

    The radius of the Earth is 6.37 x 10<sup>^6</sup> m

    Area of the Earth is: = 4 x Pi x ( 6.37 x 10<sup>^6</sup> m<sup>2</sup>) = 5.099 x 10<sup>^14</sup> m<sup>^2</sup> (or 5.1 x 10^<sup>14</sup> m<sup>2</sup>)

    Mass of O<sub>2</sub> in the atmosphere: 0.23 x (5.12 x 10<sup>^18</sup>kg) = 1.1776 x 10<sup>^18</sup> kg (or 1.2 x 10<sup>^18</sup> kg)

    Number of Litres of O<sub>2</sub> in the atmosphere is: 3.75 x 10<sup>^19</sup> mole x 22.4L/mole = 8.4 x 10<sup>^20</sup> L. (1 mole of any gas is 22.4 L)

    In order to rid of ALL O<sub>2</sub> that we have left, which is around 20.90%, we would have to keep on burning like we do now for about... 8.4 x 10^20L/1.7 x 10<sup>^15</sup>L/y = ~500,000 years. (L = Litre, y = Year)


    Now, let's look at "Hell". Since "Hell" is underground, we need to assume that it has close to 0% of O<sub>2</sub>. Now, "Hell" is said to be constantly on fire, which requires heat, and O<sub>2</sub>. If one of the three is missing, no fire.

    The main speculation now is: How long time would it take for "Hell" to consume all O<sub>2</sub>?

    Let's assume that the fires has a standard heat of around 2000<sup>o</sup>C (= 3632 F).
    For now, we will just assume that there simply is heat, so heat isn't missing.
    We now need to understand is how fast the fire uses up the O<sub>2</sub>.

    I will now use this equation to disprove "Hell". Just scroll up to see what this equation was about.

    8.4 x 10^20L/1.7 x 10<sup>^15</sup>L/y = ~500,000 years.
    NOTE: 500,000 years for 20,90% of O<sub>2</sub>.

    If "Hell" has had around 1% of O<sub>2</sub> for 6,000 years ago, and it is constantly burning at 2000<sup>o</sup>C...

    And now I am stuck. -.-

    CO2 = Carbon Dioxide. (Flammable material)
    Carbon dioxide isn't flammabe, in fact it's used in certain types of fire extinguisher...

    Ok, the way I see it you need to simplify your problem and decide what the boundaries are. I don't think it's enough to say that you want to debunk the Christian notion of hell, you need to establish exactly what it entails first. Determine the following:

    What exactly is the area of the space? From this you can estimate the amount of gas present. This leads on to the next question: What exactly is the composition of this gas? If it's standard air (which I doubt) then yes, there is approximately 20% oxygen content so that makes the calculations easier. However, the classic "fire and brimstone" imagery associated with hell suggests a sulphur-rich environment...

    Next, the fuel. If you want to go with the underground idea then you can take your pick of fossil fuels (a good choice as I can't imagine the inhabitants being very concerned about the environment)

    In my opinion there are too many variables that are open to argument for you to conclusively disprove anything conclusively until you narrow your definitions.

    Interesting, and thanks. ^^

    I'll read what it says, and if it says something that completely disproves of Hell, then I don't see why I would bother with yet another one.

    Thanks kevvy! :wink:

    Errr ... no.

    I just found it, though.

    Hell exists, but it will break loose.
