Too damned tired. I do not know how many times I have said that. The great thing about having a permanent Observatory is that it take just a second to observe. I will be bone tired, look up and see that it is clear, pop into the Observatory to view for a couple of minutes and bingo, the tiredness is gone. Double bingo and it is 02:00. Where did the time go? It has been clear all day, but now that it is completely dark, clouds are coming and going with haze inbetween. Maybe it will clear, probably after I go to bed. Clear skies!

Recently (2 days ago) I have read about 'quantum transactions'. This is where particle A sends a 'retarded wave' to particle B. Instantly, particle B sends an 'advanced wave' back to particle A. The 'retarded' and 'advanced' wave cancel out everywhere in the Universe except for the path b/w A and B. All of this happens at the same time - instantly. According to Quantum Theory, energy can only be trasfered between 2 particles and is never lost to outer space. This means that if there was a star in the Universe where nothing else existed - the star would _not_ shine! ^ B t | / i | / <- 'retarded' wave m | / e | A | / <- 'advanced' wave ------------------> space A sends a retarded wave to B / <- retarded wave ^ B t | / i | / <- advanced wave m | / e | A |
