I thought of photon but its not exactly massless..it has SOME mass so negligible..but no 0

omg.. :O.. where did you get that from? :O.. anwyays.. there are no particles then without gravity as far as i know :O

if photons dont have mass how do they have momentum?

MashyBest ResponseYou've already chosen the best response.1
that is really more subtle than you think.. when light can act like both particle and wave... which itself is mind boggling.. you think it not having mass but having momentum is a big deal? :P

You measure gravitational force on particles that's at a quantum level, which involves photons. In QM photons are considered to have a rest mass of 0, so I guess the only answer is photon. Higgs to come?

DLS look into photoelectric effect derivation and compton scattering

MashyBest ResponseYou've already chosen the best response.1
but you know what?? think of this .. if two photons of light are moving parallel to each other(in vacuum)... if they put force of gravity on each other, then their velocities WOULD CHANGE right.. i don't care how small that change is.. but it would change.. ?? but remember relativity?? light cannot have ANY OTHER speed than C.. in vacuum.. regardless of what crap you do!!.. so they cannot put gravitational force on each other :O hmm.. how is that argument? :O

for why it has momentum, no higgs would give more knowledge, it gives mass.

or maybe not.. you can use general relativity to explain that.. so never mind :D

Photoelectric determines relationship between energy and frequency ... E proportional to (a + bw) where w = angular omentum so E = Hbar(ww_a) = h(v  v_a) photon rest mass is zero for general relation of energy, so it can be written as E^2 = (m_0*c^2)^2 + p^2c^2 = Hbar^2w^2 and can cancel to momentum p = Hbar * k, where k = w/c (wave number) therefore the momentum of a photo can be given as p = Hbar * k bear in mind wave particle duality, how a wave can have momentum is a toughy, yet quite beautiful
