How has Marie Curie helped us understand the universe in which we live?
I will be happy to critique your ideas.
Okay well i'm thinking along the lines of this:
She created the theory of radioactivity. Although Henri Becquerel discovered radioactivity in 1896, Marie Curie and her devoted husband discovered that radioactivity is much more complicated than people thought.
Although I need more info on how much more complicated it is.
You can google radioactivity to find that out.
All this was discovered at the time the nucleus was being discovered, and it was unclear why the instability was present in some atoms, in some isotopes. Curie developed the methodology to understand this.
