The quantum theory of field is sometimes known as second quantization. There are two distinct types of field in physics: 1. Scalar field. 2. Vector field. For each field, a force is supposed to be associated with it. But for the scalar field, this force is zero. This zero-force destroys the built-in sense of "direction" for the field. There were four known fields before Standard Model. These are the EM field, the strong field, the weak field, and the gravity field. All these are agreed to be vector fields with their respective quanta as the photon, the gluon, the W's and Z, and the graviton. The integral spins of these quanta make them bosons. But the graviton is a much more complicated vector (tensor) boson because its spin is 2. After the Standard Model, a new type of scalar field is formulated in physics. This is the Higgs field. The parameter for this field is the mass. Mass is a scalar quantity. It has no sense of direction. Both graviton and Higgs boson are yet to be found. The graviton has zero mass, while the Higgs boson is theorized to be a very heavy boson. The concept of mass is explicitly stated in only two force equations in physics: Newton's 2nd law of motion (inertial force) and his law of universal gravitation (gravity force). Yet in Einstein's general relativity, these two mass-forces are equivalent. Both graviton and Higgs boson must somehow be connected at a deeper level. Say at the Planck scales of length, time, and energy. Maybe the graviton and the Higgs boson are just two different way of viewing the same fundamental particle of a quantized scalar field?
