it says that they are electrically neutral and that they travel at the speed of light. i don't really understand what it means about "neutrinos traveling through matter undergo a process analogous to light traveling through a transparent material"

is it because they have little mass and no charge? So this means they would have limited interaction with heavier charged matter?

Particles from space? Which particles arrive from space and pass through the earth? How is this possible? Are they called neutrinos?

its an explanation someone gave me today but I am still not sure i understand it completely.

does this make sense? the oil it acts like a thin film. The light of different wavelengths (colors) refract and reflect at different angles, and the reflections add up or cancel each other out by superposition depending on the wavelength and angle.

Black oil - colours? [b]1. How does black oil on a windscreen appear to be all colours? [b]2. Is it because black absorbs all frequencies of light? [b]3. I'm not sure how to answer this question can anyone help?
