visible light - How would neutron matter appear to the naked eye?


Neutron matter is matter comprised entirely of neutrons, as it exists in neutron stars.


Most optical phenomena encountered in everyday life, such as light reflection and spectral absorption (i.e. color appearance) are the result of mechanisms involving electrons.


My simple question: How would a macroscopic sample of matter consisting entirely of neutrons (without electrons) appear to the naked eye? Assume the matter is degenerate and stable.


Let me add here that I'm not specifically asking about the appearance of a neutron star, as Wikipedia states that it would radiate so much that it appears white.

classical mechanics - Moment of a force about a given axis (Torque) - Scalar or vectorial?

I am studying Statics and saw that: The moment of a force about a given axis (or Torque) is defined by the equation: $M_X = (\vec r \times \...
