A hundred thousand million Stars make one Galaxy;
A hundred thousand million Galaxies make one Universe.

I deal with the view now tentatively held that the whole material universe of stars and galaxies of stars is dispersing, the galaxies scattering apart so as to occupy an ever-increasing volume. But I deal with it not as an end in itself. To take an analogy from detective fiction, it is the clue not the criminal.

I am a detective in search of a criminal―the cosmical constant. … I think I have enough evidence to justify an arrest.

Astronomical measurements are, without exception, measurements of phenomena occurring in a terrestrial observatory or station; it is only by theory that they are translated into knowledge of a universe outside.

Aether is everywhere.

But what, therefore, am I? A thing that thinks?

What possible justification could there be for the choice of a particular boundary condition―aside from the fact that it works, i.e. that it leads to what we observe?

When the ‘system’ in question is the whole world where is the ‘measurer’ to be found?

The problem is that quantum mechanics is fundamentally about ‘observations’. It necessarily divides the world into two parts, a part which is observed and a part which does the observing.
