Antiparticles Garrett lisi Theoretical physics Theory

In summary, antiparticles are particles with opposite charge and quantum spin to their corresponding particles. In Garrett Lisi's E8 Theory, they are represented as mirror images in a 248-dimensional matrix called the E8 Lie group. The theory suggests that antiparticles can be seen as moving backwards in time and play a role in the interactions of particles in the universe. While there is currently no direct evidence for their existence, the success of the E8 Theory in predicting known particles lends credibility to its predictions about antiparticles. These differ from dark matter, which is a separate concept in the theory. While antiparticles have been created and observed in experiments, their creation and observation within the context of the E8 Theory is still an

Greetings all :)

I would like to know please how antiparticles fit into Garrett Lisi's E8 Theory.

Thanks!

Let's ask him @garrett

1. What are antiparticles in Garrett Lisi's E8 Theory?

Antiparticles are particles that have the same mass as their corresponding particles, but with opposite charge and quantum spin. In Garrett Lisi's E8 Theory, antiparticles are predicted to exist as mirror images of particles in a 248-dimensional matrix called the E8 Lie group.

2. How do antiparticles fit into the E8 Theory?

In the E8 Theory, particles and antiparticles are represented as different symmetries within the E8 Lie group. The theory suggests that antiparticles can be thought of as particles moving backwards in time, and the entire universe can be seen as a combination of particles and antiparticles interacting with each other.

3. What evidence supports the existence of antiparticles in the E8 Theory?

Currently, there is no direct evidence for the existence of antiparticles in the E8 Theory. However, the E8 Theory has been successful in predicting the existence of known particles and their properties, which lends credibility to its predictions about antiparticles.

4. How do antiparticles differ from dark matter in the E8 Theory?

Antiparticles and dark matter are two separate concepts in the E8 Theory. Antiparticles are predicted to exist as mirror images of particles, while dark matter is a hypothetical form of matter that does not interact with light and has not yet been observed.

5. Can antiparticles be created or observed in experiments?

Antiparticles have been created and observed in experiments, such as in particle accelerators. However, the creation and observation of antiparticles in the context of the E8 Theory is still a subject of ongoing research and has not yet been achieved.
