I was thinking about "zero capital entrepreneurship". Create a business (something) without investing anything (esp. money) was the core idea behind this. However,can something come out of nothing? The answer can be explored in philosophy.

There is one and only example of something which most probably came out of nothing. And that is our universe. If you believe things should have some kind of beginning, then this universe possibly began from nothing. Or that will be your finding if you go on tracing out its ultimate beginning. Surprisingly, it has come to become everything as we know of today.
