That the enclosed hydrogen gas caught fire and caused the entire "balloon" portion to explode.
There is another theory though, and that is that the paint on the balloon part, or "dope", which is designed to keep the gases inside, in the case of the Hindenburg airship, included two of the three main ingredients of thermite, which caused the catastrophic explosion. This theory though, no matter how plausible it may seem, has since been disproved by the Mythbusters, but feel free to ignore their conclusive tests if you so wish.
Static electricity discharge ignited the hydrogen cells.

BIG BANG THEORY
Yes, along with many, many other theories.
The Big Bang Theory
The most known theory in quantum mechanics would be the Broglie-Bohm theory. Other popular theories are the string theory, quantum entanglement, and SchrÌ_dinger's cat.
Well, the obvious answer is that the Hindenburg was an airship (zeppelin), and the Titanic was an ocean liner. Most deaths in the Hindenburg were from fire or jumping from the airship, while most deaths on the Titanic were from drowning or exposure. Finally, there were many more deaths on the Titanic than on the Hindenburg.
hybrid theory
The most popular theory would be that they traveled across the Barring Straight Land Bridge.
Self-motivation theories are very popular and are used for marketing and psychological causes. One of the most popular theory is one developed by Maslow according to which all human beings have hierarchy of needs.
Choosing whether to do the Hindenburg or the Titanic for your project is a tough decision. Both events were huge distasters but the Titanic is probably a more popular subject.
