Brian Russell's Laws of Software Relativity (cf. Belady and Lehman's Laws of Software Evolution)
* As a software project approaches release, its mass increases.
*The energy required to release a software project is inversely proportional to the time before a scheduled release.
*It takes infinite energy to release a finished product on time; therefore, all software projects are both incomplete and late.
*Time is relative to the observer of a software project. The last month of development appears to an outside observer to take a year.
*If a software project becomes too large, it will collapse into a black hole. Time and money are absorbed but nothing ever comes out.
