The higgs boson has a mass of aprox 126.5 Ge/V^2.
How can the higgs boson have mass if it is the particle that gives things mass. Do higgs bosons always come in pairs so that they interact with each other to give each other mass?
And how do higgs bosons interact with massive objects? i.e., what particles do they exchange? Like two electrons exchange photons, doesn't a higgs particle and a massive object have to exchange some particles too? Do they exchange strings as in string theory?

Thank you very much for any replies :)

I am currently in the process of validating a theory which i have been working on for some time. I would like to get an expert's opinion on the work i have done so far but for safety purposes i will refrain from exposing my developed ideas and work in this manner. I have a question which i hope can be clarified by a professional .My physics professors are too lost into their world of classical mechanics that they just ridicule my proposals due to the fact that they get to the point where they become counter intuitive. they do not seem to be quite knowledgeable on the field and as a result they are not able to provide me with a reasonable answer. The Tachyon particle is not widely considered from the fact that it obtains a negative mass and form of energy, thus it it is comprised of imaginary values. Is it not safe to assume that the particle itself can exist but to us it would be nonexistant due to the fact that we occupy a three dimensional frame and the particle itself is dimensionless like a charge?

Given that H=H0 + Hˈ, Where Hˈˈ= bx4 and b is constant. (i) Use Pertubation Theory to solve for the the first non-vanishing correction to the energy. (ii) Using exact solution repeat (i)

The unpertubed Haniltonian of harmonic oscillator is given as: H0= P2/ 2m+ ½ mω2x2. If the intereaction Hˈ(x)=bx is added to the unpertubed Hamiltonian, where b is a constant. Find (i) The exact calculation of the Energy. (ii) Use Pertubation theory to find the first non-vanishing correction to the energy. (iii) Compare and contrast (i) and (ii)

Quantum mechanics stipulates that even at absolute zero an oscillator has a zero point energy of hv/2. Use this result to obtain a correction to the Debye expression for lattice energy.

1. A photon and an electron each has a de Broglie wavelength of 5nm. Compare their energies in eV(electovolt)
b) If the proton is confined to a nucleus of radius 2*10^-14m, estimate the uncertainty in its linear momentum.


Equations:

De Broglie wavelength = h/p --> h is Planck's constant and p is the linear momentum(mass*velocity).

Also, de Broglie wavelength = h/ sqrt(2m(e)deltaV) --> m = mass , (e) is the absolute value of the charge of the electron(-1.6*10^-19) and delta V is the stopping potential.

Heisenberg's Uncertainty Principle: delta x * delta p is greater or equal to h/2pi --> x is the position, p is the linear momentum (mass * velocity) , h ( Planck's constant 6.63*10^-34 J*s )

what would hit the ground first if you shot a gun straight forward and dropped something like a teddy bear from the exact same height at the exact same time.
