Hi, Members and Gurus!
"There is no substitute for Mass. Mass stops bullets. Mass stops gamma radiation. Mass stops (or at least slows down) bad guys from entering a home and depriving its residents of life and property. Sandbags are cheap, so buy plenty of them. When planning your retreat house, think: medival castle."
It's an excerpt from James Rawles's book, "How to survive the End of the world as we know it".
The "mass" in the excerpt. Among the meanings of mass in Webster Dictionary...
1. The property of a body that causes it to have weight in a gravitational field.[ For example, the book is 2 kilograms in mass. Mass as in Einstein's theorem E=MC
2 ]
2. An ill-structured collection of similar things (objects or people).[
Wordnet]
3. (Roman Catholic Church and Protestant Churches) the celebration of the Eucharist.[]
4. A body of matter without definite shape; "a huge ice mass".[For example, a mass of clay]
--------------------------
The "mass" is to be understood as the meaning of #1 (The property of a body that causes it to have weight in a gravitational field), or #4 (A body of matter without definite shape)?
I assume that number 4 meaning is the only option here, but some people don't agree. Some people think number 1 is the right meaning of "mass" in the excerpt and some people think both interpretation is possible.
What is native speaker's sense of English regarding the word, "mass" here?
