Is there such a thing as anti-energy?

Question

I know that antimatter exists-or used to exist, and that matter is just energy in a different state like what ice is to water, but does anti-energy exist or has it ever existed?

Answer 1

There's all kinds of theories out there about anti-energy. As usual with scientists, they are basically floundering about in a quagmire of words that don't compute from one field of science to another. There are, of course, also indications that the true frontiers of our knowledge about anti-energy are actually much farther along than us mere mortal peasants are privvy to. Gravity's involved someway. But, the answer below is your basic "official" answer for now:

"When people speak of anti-matter, it's important to recognize that anti-matter isn't some sort of 'negative' matter. An anti-particle is just as real as any other particle. If you use Einstein's famous E=mc2 relation you find that an anti-particle has positive energy, since it has a mass which is identical to the mass of its partner 'particle.' The 'anti-' part of the name just signifies the fact that the quantum numbers that the particle has are opposite of those of the corresponding particle. Most people have heard that anti-matter annihilates with matter and gives rise to energy. This is a result of the two particles having exactly opposite quantum numbers -- but 'particles' in our everyday world annihilate into new particles all the time too. Energy, by contrast, is a relative concept. The important physical quantity is the difference in energy between any two states of a system. We thus always speak of positive energy values and typically eliminate solutions which give rise to negative energies as unphysical. In short, then, the existence of anti-matter does not imply the existence of some sort of anti-energy."

Answer 3

Unfortunately, there is an endless set of ideas about what is antimatter, so for each there would be a different 'spin' for antienergy (that could be a pun!). By the strictest definition, matter is antienergy. There is even a distinct set of properties for the exchange process between them.
My set of ideas is that antimatter is limited to residing outside our universe. A thermonuclear explosion creates a separate reality within its Event Horizon, and the rules of matter and energy don't match ours. This small universe continues until the explosion runs out of fusionable material and shuts down. You got antimatter, and antienergy.
My model is that matter must be traveling at zero velocity in order to leave our universe and enter another (a conservation of energy between universes thing). If the alternate universe has a vibration rate which exceeds the speed of light, then to this antienergy, our universe's energy wopuld seem like matter in its slowness.

Answer 4

Most people around here seem to think that energy is a substance on par with matter. It is not. It is a quantitative property like mass, momentum, or charge. An antiparticle is a particle (substance) with the same properties as another particle, except for having opposite charge. But since energy is already a property itself, how can it have an "anti", except perhaps if you mean something has a negative energy. Well, yes, you can do that. Gravitational potential energy, for example, is always negative.

Answer 5

I don't think there is such a thing.
When matter and antimatter meet (like an electron and a positron), energy is generated, along with other elementary particles.
Actually, I believe antimatter is still matter, but with different subatomic particles. The quarks that constitute the nucleons (protons and neutrons), and the leptons (like the electrons or positrons) just have different properties (spin, color, ...)

Answer 6

Possibly

The only reason that anti-matter is anti-, is because it has the opposite charge from an identical particle.

With energy, all energy is identical, except for its forms. But since antimatter and matter anihilate, and inerta and energy annihilate, inertia maybe antienergy.

Inertia!

Answer 7

Anti matter exists and is a mirror image of normal matter. However the energy that it is made from is the same energy that goes into normal matter.

Answer 8

No
every atom has amovement caused by temperature and electrons moving so as this requires energy everything has a limited amount
only space would nt

Answer 9

Above answers are all good but just to clarify, anti matter has positive mass

Answer 10

matter= energy by Einstein's E=mc^2
antimatter = matter
therefore, antimatter = energy

Thus, the analogy of matter to antimatter does not apply to energy, as they are both sub-categories of energy. Technically,
"anti-energy" could just be anti-matter, b/c matter is a sub-category of energy.
