Every one loves to quote the E=MC2 equation. But, only one term in that equation is defined. That term is c, the speed of light.
But energy has been over-defined.....it can mean many, many things. What is the exact definition of energy? Look at all the different forms of energy we have. And each form has it's own properties. So.......what is fundamental energy?
And mass has never been defined either. To this very day, in 2022, we have no narrative of mass and matter. What exactly is mass?
Is energy an entity?.....or a property of an entity? Is mass an entity or the property of an entity? Only the behavior and properties have been measured, but no ones knows what mass and energy truly is.
What exactly are we talking about? Are energy and mass two separate entities that can be interchanged.........or are energy and mass the same thing, in different forms?
What do you think?
