This type of energy is not explained by gravity, or by residual hydrocarbon fires, and is unusual in light of the amount of water dumped on the fires. It is, however, plausibly explained by the use of high-energy explosives[16], capable of igniting exothermic reactions[17] in materials in the rubble that are both hot enough to melt iron and are self-sustaining for a period of time. Thermate-like explosives contain their own source of oxygen[18] and cannot be put out with water. The observable, scientific evidence suggests a strong possibility explosives[19] were involved in the destruction of the World Trade Center towers. The 9/11 Truth movement believes the evidence is strong enough to warrant a well-funded, independent, impartial investigation designed to include this hypothesis in its analysis.
