SUMMARY

The smallest portion of energy currently recognized is zero, as discussed in the context of quantum mechanics and particle physics. The conversation highlights the ambiguity surrounding the concept of energy, particularly in relation to the microwave background and neutrinos. The second smallest energy is not definitively established, as energy can be arbitrarily small depending on the frame of reference. The discussion emphasizes the need for clarity regarding which particles have been measured with the lowest known energy.

PREREQUISITES
  • Understanding of quantum mechanics principles
  • Familiarity with the concept of energy quantization
  • Knowledge of the Standard Model of particle physics
  • Basic grasp of the relationship between energy and frequency (E=hf)
NEXT STEPS
  • Research the properties of neutrinos and their energy levels
  • Explore the implications of the microwave background radiation on energy measurements
  • Investigate the concept of energy quantization in quantum field theory
  • Learn about the lowest energy states of various particles in particle physics
USEFUL FOR

Physicists, students of quantum mechanics, and anyone interested in the fundamental concepts of energy and particle physics.

What is the smallest portion of energy known so far? Could it be found within microwave background or amoung neutrinos?
Thanks!

0. And that's pretty exact.

Cheers,
Jazz

That's surely is, but is 0 SOME energy? In avoidance of math-phys-philo discusse on this mater, what has the second smallest energy already to known?
 
It's the same as the second smallest difference between two real numbers.
 
Ok. What posses the lowest energy already detected?
 
It's arbitrary, since in some frame it can be made as small as you want.

Yes, as E=hf where f can -> 1/inf, it might be. But what particle has been yet measured with the lowest known energy and what "particle" is suppossed to be?
