# What gives mass to black hole?

I like to know when a dying star collapsed into a black hole, is there anything inside or on the event horizon that is interacting with higgs field?

• The Higgs interaction adds very little mass to matter. 99% of the baryonic mass comes from the energy of gluons that don't interact with the Higgs field. – safesphere Jan 11 '19 at 8:01
• @safesphere So the statement that the Higgs field explains mass is 99% incorrect. – my2cts Jan 11 '19 at 8:33

General Relativity treats mass and energy as equivalent and related by Einstein's famous equation $$E=mc^2$$. Both mass and energy contribute to the curvature of spacetime. So while we talk about a black hole having a mass of $$M$$, we could equally well talk about it having an energy of $$Mc^2$$. Both are the same in GR. This means we do not need to invoke the Higgs field to explain the gravitational field of a black hole, or indeed any massive object. We could have constructed our black hole from massless photons and it would still have a mass $$M$$ related to the energy $$E$$ we put into it by $$E=Mc^2$$.
