I don't know much physics so it's not that easy to understand what a Higgs Boson or a Higgs field is. According to Wikipedia, a Higgs field is theorised to be the mechanism for giving elementary particles mass. For a lay-person, this makes me think that a Higgs field is something to do with gravity but from reading another thread here, they seem to be different things. From reading this thread https://www.physicsforums.com/showthread.php?t=620532 it seems that a Higgs field has the same strength (in a vacuum) everywhere in the universe, just like the aether of 120 years ago. So this seems to mean that a Higgs field and gravity are sort of related. A particle has mass because of the Higgs field and particles that have mass interact with each other via a gravitational field which decreases with distance. Is that correct? So then, what is a Higgs Boson? If a Higgs Boson decays very quickly, does it exist naturally anywhere in the universe or only when high energy collisions occur? Does the Higgs field have anything to do with the expansion of the universe/ space? Is the strength of the Higgs field decreasing as space expands? I heard that 70% of the universe is dark energy, 25% is dark matter and 5% is matter. Is the Higgs field anything to do with dark energy? Is a Higgs field energy itself that can turn into mass? Is "energy" a general term that has specific forms such as a photon or the momentum of a particle with mass - or what exactly is "energy" - and when mass gets transformed into "energy", what exactly does it get transformed into? Thanks for any information.
