Neutrino's and gravity

January 28, 2007 5:01am CST
If neutrino's have a positive mass then they should be affected by gravity the same way which we are, and therefore should find their resting place at the centre of the earth, yes ? But this apparenlty doesnt happen, can anyone say why ?

this is coz of the very light weight of the neutrino particles. as we know that F= mg where f is force , m is mass, g is gravitational force and is constant. so for a neutrino particle the value of mass is in the range of 10^-26 and when this small value is multiplied with the gravitational constant then it gives very low value of force and this is why the force exerted on the particle is so small that it can be neglected.
