does energy exist with antienergy?

Answer 1

As far as we know, there is NO antienergy.

Answer 2

As per Henri Poincare's Energy equation;
mass x C^2 = Stuctural Energy, antimass x c^2 = antienergy

or matter energy =- antimatter Energy. Hence its energy process equivalency.

Newton's 3r law =to every energy there is an equal and opposite energy or in general terms to every action there is an equal and opposite reaction. Or to every active power there is a reactive power.

Newton's third law is very simple.

Answer 3

According to Einstine's famous E=mc2 equation, anti-energy is not only possible, it must exist. If matter equals energy, than antimatter equals antienergy. It is simply antimatter with some kind of apllied energy.
