    Energy
In summary, the conversation discusses the smallest portion of energy known so far and whether it can be found within microwave background or among neutrinos. The participants also discuss the second smallest energy and the lowest energy already detected, mentioning the concept of E=hf and the measurement of particles with the lowest known energy.

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,

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?
 
  • #4
It's the same as the second smallest difference between two real numbers.
 
  • #5
Ok. What posses the lowest energy already detected?
 
  • #6
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?
 

1. What is the smallest portion of energy?

The smallest portion of energy is known as a quantum, which is the fundamental unit of energy in quantum mechanics.

2. How is energy measured in quantum mechanics?

In quantum mechanics, energy is measured in terms of Planck's constant, which is a fundamental constant of nature.

3. Is there a limit to how small energy can be?

According to the principles of quantum mechanics, there is a limit to how small energy can be, known as the Planck energy. This is the smallest possible amount of energy that can exist.

4. Can energy be divided into smaller parts?

In classical physics, energy can be divided into smaller parts, but in quantum mechanics, energy is considered to be quantized and cannot be divided into smaller parts.

5. What is the relationship between energy and matter?

In Einstein's famous equation, E=mc², energy and matter are shown to be interchangeable, meaning that matter can be converted into energy and vice versa.
