Discussion Overview

The discussion revolves around the properties of anti-particles, specifically regarding their kinetic energy and velocities. Participants explore the implications of negative kinetic energy and the nature of anti-particles in terms of energy, mass, and charge.

Discussion Character

  • Debate/contested

Main Points Raised

  • One participant questions whether anti-particles have negative kinetic energy, suggesting this could imply they possess imaginary velocities.
  • Another participant asserts that anti-particles have positive energy and mass, along with real velocities, contradicting the initial claim.
  • A third participant expresses surprise at the correction.
  • It is noted that anti-particles have opposite charge compared to their corresponding particles.

Areas of Agreement / Disagreement

There is disagreement regarding the kinetic energy of anti-particles, with one viewpoint suggesting negative kinetic energy and another firmly stating they have positive energy. The discussion remains unresolved on this point.

Is it true that they have negative kinetic energy; wouldn't this mean that they have imaginary velocities? :confused:

I'm sure I've read this somewhere but I just need to confirm if it's true or not.

No, it's not true. They have positive energy and mass and real velocities.
 
Oh...damn
 
They have opposite charge though
