SUMMARY

The early universe exhibited low entropy due to the unique nature of the Big Bang, which was an explosion of space rather than a conventional explosion. This means that every point in the universe expanded simultaneously, preventing any initial communication between points. As a result, the distribution of matter and energy remained relatively uniform and ordered during the initial phases of expansion, contrary to expectations of high randomness.

PREREQUISITES
  • Understanding of basic thermodynamics principles, particularly entropy.
  • Familiarity with cosmological concepts, specifically the Big Bang theory.
  • Knowledge of gravitational forces and their role in matter distribution.
  • Basic comprehension of space-time dynamics and expansion.
NEXT STEPS
  • Research the principles of thermodynamics, focusing on entropy and its implications in cosmology.
  • Study the Big Bang theory in detail, including its effects on the early universe's structure.
  • Explore gravitational interactions in the context of the early universe and matter clumping.
  • Investigate space-time expansion and its significance in modern physics.
USEFUL FOR

Students of physics, cosmologists, and anyone interested in understanding the fundamental principles of the universe's formation and entropy dynamics.

Entropy has been defined as nearly synonamous with randomness (http://www.google.com/search?hl=en&...&sa=X&ei=PyWxTPLOFcT6lwf-rZmYDQ&ved=0CBIQkAE"). In our every-day experience things naturaly progress from a state of less entropy to a state of more entropy. This observation has even been elevated to the status of a physical law of thermodynamics. My question is why did the early universe have such low entropy? It seems like everything exploding from a single point would lead to a highly random distribution of mater and energy.

Hello. This is my first post in these forums. I have no education in physics and little in mathematics beyond the basics. So, definitely take what I have to say as the opinion of the curious only. Looking forward to some real answers later. :)

One thing to keep in mind is that the "big bang" was not like a typical explosion. In any explosion we are familiar with, it occurs in space, while the "big bang" was an explosion of space. So, there is no central, single point of energy. The central point is every point in the ever expanding space.

Also, it seems to me that during the first phases of this expansion each point had no time with which to communicate with any other point. Even when gravity split and became a distinct force, the very small clumps of matter that were present did not have time to attract or act upon the matter surrounding them.
