We all know E=MC2, matter is made of energy. So, I was wondering how we can be sure this is universally true.

Is it at all possible that matter might exist that is made up of other energy basis, such as time based, gravity based, Weak Nuclear Force based and so on.

Assuming these types of matter would not interact with the Higgs Boson, might they still exist but we cannot perceive them, like a magnet cannot perceive wood. Magnetic fields only recognize metallic based matter. Perhaps the Higgs Boson is like that, it’s field will not recognize matter based on things other than energy.
