Uniformity of Particles Formed After Big Bang

Click For Summary

Discussion Overview

The discussion revolves around the uniformity of particles formed after the Big Bang, particularly focusing on how particles emerged from a cooling plasma and the implications of their identical properties. The scope includes theoretical considerations and conceptual clarifications regarding particle physics and the nature of elementary particles.

Discussion Character

  • Exploratory, Conceptual clarification, Debate/contested

Main Points Raised

  • One participant questions how particles can emerge uniformly from a cooling plasma, likening it to Lego bricks forming without a mold.
  • Another participant suggests that elementary particles are uniform because they are excitations of the same quantum fields.
  • A different perspective uses the Lego analogy to differentiate between elementary particles and larger structures like dust particles, planets, and stars, emphasizing that while atoms of the same element are identical, larger celestial bodies vary in size and properties.
  • Another participant argues that the plasma did not create new particles but was composed of the same particles, indicating that the uniformity arises from the nature of the particles themselves rather than a random process.

Areas of Agreement / Disagreement

Participants express differing views on the analogy used to explain particle uniformity and the nature of particles formed from plasma. There is no consensus on the appropriateness of the Lego analogy or the implications of particle formation.

Contextual Notes

The discussion highlights assumptions about the nature of particles and the state of plasma, as well as the definitions of uniformity and identity among particles. The relationship between elementary particles and larger structures remains unresolved.

In the beginning there was the Big Bang...then there was plasma...then there were particles, and so on...

Now, how is it possible that from a cooling plasma, randomly (?) emerged particles that are so perfectly uniform?

I mean, all neutrons are exactly the same...size, mass, properties...and this is true for each known particles.

It's a bit as if, from melted Lego plastic, were emerging bricks of exactly similar dimensions, shapes and weight...without the use of a mould!

How do we explain the uniformity of these randomly formed particles?

The building blocks are the elementary particles. Those are the same because they are all excitations of the same quantum fields.

In the Lego analogy, the Lego pieces are the dust particles, planets, stars and so on - they are all different. Lego plastics consists of atoms, and atoms of the same element and isotope are identical as well.

that plasma was made up of the same particles (And maybe some additional heavier ones)...it didn't create them... (plasma is a state where particles are almost free).

Then you are wrong, with your lego analogy... the Sun is not the same size as all the other stars, the Hydrogen atoms in the sun are almost identical to those in some other star though...
