What is the force called that holds all the molecules together that make everything? Is it gravity, magnetism, or something similar?

It depends upon the molecules really but in essence it is magnetism (but not ferromagnetism between iron objects, merely +ve attracting -ve & vice versa). On the small scale, i.e. molecules etc., gravity plays a very samll role in pulling mass together.

These are two of the most powerful forces in the universe - way more powerful than gravity Strong Nuclear force Weak Nuclear force There are only four forces in the Universe - if I remember from physics calss - the two above, and also Electromagnetism and Gravity :)

Electromagnetism. All the four forces are involved, but electromagnetism is really the one you're after: Stuff, such as cheese, doesn't fly apart because its molecules are held together by electric forces. If gravity faded out, anything loose on Earth, like seas, atmosphere and people would drift away, but Earth itself would probably stay in one piece more or less. The nuclear forces act to keep the nuclei together but this aspect rarely shows up in ordinary phenomena. For most purposes (including most chemistry and biology) each type of nucleus can simply be considered a different elementary particle.
