Negative gravitational energy - negative energy gravitons?

In summary: Matter=positive, antimatter=negativeIn summary, the conversation discusses the concept of negative energy in relation to gravity and whether the mediator particles, gravitons, would also have negative energy. The possibility of assigning energy to virtual particles and the implications of magnetism being mediated by photons are also brought up. It is noted that in the zero energy universe theory, gravity is considered to have negative energy, but this may not apply in all situations and further research is needed to fully understand the nature of gravity and its mediator particles.

We know that gravitational energy is negative (zero energy universe theory). If the mediator particles (bosons) of the gravitational interaction are gravitons, then the energy of the gravitons would be negative?

Hmmm, not sure. Can you assign energy to a virtual particle in this situation? Or at all?

Magnetism is attractive and mediated by photons. Does that imply photons have negative energy?

The magnetic energy is positive, and non negative.

Interesting question, let's think about that for a second. In this particular model it is a negating energy, however DM in this model is positive. DM as we know doesn't have a charge as it is considered to be a spin zero weakly interactive particle.

Gravity in the FRW metric is a positive force that applies a positive pressure with the cosmological constant attributing to the negative pressure.

In super symmetry their is a predicted graviton and gravitino although super symmetry has yet to discover any of the super symmetry particles it predicts it may or may not be valid.

Given the above my take is that gravity is negative only for the energy balance of this particular model. Trying to assign a permanent charge to it that applies in all situations would need to look at its spin, as well as look for its opposite charge partner. The electron for example has two possible charges positive and negative, however it is still the same particle just a different charge. Gravity does not have the same electromagnetic charge scenario, and we have yet to validate the gravitino ( or a graviton for that matter). Its quite possible gravity is an effect of space-time rather than a boson carrying force.

So for the model it is indeed negative, but I wouldn't apply that outside the energy density=zero modelling

edit forgot to add matter/antimatter.. by convention matter is positive with anti matter being negative. That would also apply to the graviton/gravitino
 

Related to Negative gravitational energy - negative energy gravitons?

1. What is negative gravitational energy?

Negative gravitational energy refers to the concept that objects with negative mass would experience a repulsive force rather than an attractive force in the presence of positive mass objects. This is in contrast to the traditional understanding of gravity, where objects with positive mass attract each other.

2. Can negative energy gravitons exist?

There is currently no evidence for the existence of negative energy gravitons. The existence of negative mass and negative energy is still a theoretical concept and has not been observed in nature.

3. What would happen if negative energy gravitons were discovered?

If negative energy gravitons were discovered, it would challenge our current understanding of physics and could potentially lead to new theories and models to explain their existence. It could also have implications for our understanding of the universe and the laws of physics.

4. How would negative energy gravitons affect space and time?

If negative energy gravitons were proven to exist, they could potentially have an impact on the fabric of space-time. This could lead to changes in the behavior of objects and the laws of physics, similar to the effects of normal gravitons.

5. Are there any experiments being conducted to test the existence of negative energy gravitons?

Currently, there are no specific experiments being conducted to directly test the existence of negative energy gravitons. However, scientists are continuously researching and testing various theories and models that could potentially support the existence of negative energy and negative energy gravitons.
