Question

In a news item in EuropaPress, I read that for the first time the spin of electrons has been measured, which it defines as the curvature of the space where they move. How does this relate to the intrinsic angular momentum of the electron? Thank you.

Answer 1

I apologize for any confusion, but the information you mentioned is incorrect or might have been misinterpreted. The spin of an electron is not directly related to the curvature of space where it moves. Let me clarify the concepts for you:

1. Spin of Electrons: Spin is a fundamental property of elementary particles such as electrons. It is often described as an intrinsic form of angular momentum. However, it's important to note that spin is not the same as the classical notion of a spinning object. Rather, it is a quantum mechanical property that does not have a direct classical analogue.

2. Curvature of Space: The curvature of space is a concept from general relativity, a theory of gravity proposed by Albert Einstein. According to general relativity, massive objects like planets and stars curve the fabric of spacetime, causing the paths of other objects to deviate in their presence. This curvature is related to the distribution of mass and energy in space.

While both spin and the curvature of space are fascinating concepts in physics, they are distinct and unrelated phenomena. Spin is an intrinsic property of particles, while the curvature of space is a consequence of the presence of mass and energy. There is no direct connection between the two as described in the news item you mentioned.
