My understanding of the Higgs ocean comes from Briane Greene's The Fabric of the Cosmos. The book says that the Higgs field is a nonzero value field, and that if enough energy where put into it, enough to raise it to zero value, then mass would no longer exist since there would be no resistance between paricles and the Higgs field, and that all particles would travel at the speed of light. So, if when I heat something up, giving energy to the Higgs field, then the Higgs field should be getting closer to a zero value and inertia should be decreasing. But if I take into account relativity then by heating the object up I am giving it energy, so its mass is increasing, therefore there should be more inertia when something is heated up. And at the temperature of electroweak unification, 1015degrees, then the particles shouldn't be zooming around at the speed of light, they should be heavily weighed down by there total mass. Can anyone please clear this up to me? Thanks.
