Something from nothing?

[Butch]

Quantum physics attempts to describe physics at the smallest level... Ultimately aren't we seeking the point at which there is something from nothing, the edge of existence?

[StringJunky]

Are notions of size and having a discrete existence, i.e particle-like, meaningful at that level when things are actually excitations in fields?

What constitutes a field?

A field is something, even a "flat" field has propertie(s), granted the field must be affected for evidence of those properties.

Which came first, the chicken or the egg?
