`Great Debate’ Review and History – University of Arizona
In 1924 Edwin Hubble located Cepheid variables in the nearest major spiral nebulae, M31. This had immediately followed a period where stars in this nebulae were being resolved. When confronted with this evidence Shapley immediately admitted he was wrong on the spiral nebulae issue – an issue that he did not consider at the heart of the 1920 debate.

The Cepheid stars were apparently very faint, which meant that the Andromeda Nebula was outside our own galaxy, and constituted a galaxy of its own. From the Cepheid period-luminosity relation, the distance to the Andromeda Galaxy is found to be 700 kpc = 2.3 million light years.

Atoms, the Redshift and the Zero Point Energy. Introduction to atoms and their emitted light: Many people are familiar with the basic structure of an atom. There is a central nucleus made up of positively charged protons and neutral neutrons. Surrounding this nucleus and some distance from it are orbiting electrons of negative charge.
