I wish white holes existed

Hi:

I wish white holes [opposite of black holes] existed. It would make
life more interesting. However, there is a problem. The existence of
white holes requires that:

1. Entropy of an isolated system which is not in equilibrium can
decrease over time and approach minimum value even at equilibrium.

AND

2. In a system, there is a process that occurs that can decrease the
total entropy of the universe.

AND

3. Heat can spontaneously flow from a material at lower temperature to
a material at higher temperature.

AND

4. It is possible to convert heat completely into work in a cyclic
process.

AND

5. All of the above can occur in macroscopic systems

Sadly all 5 are impossible.
