Light can come from sources lightyears away. Can matter—atoms or molecules—escape the gravity of their origins to start similar journeys through space to our galaxy, solar system, and planet?
The electric universe model says matter that reaches earth comes from our own star.

IMPORTANT WORDS: ". . . IS THOUGHT TO come from exploding supernova stars, . . . ."
Science requires evidence. How was evidence obtained?

@EarnestEccentric Thanks for your comment and the wikipedia link.
I’m skeptical about the on line magazines cited in posts here. They seem intended for people who, though interested in science, have not studied enough science to know the scientific method and what it requires.
I see you and I have joined the Physics group here. Its originator appears to have lost interest in it. Hoping to stir interest in that group, I wrote a post there and included a link to this discussion.
