B Particles uniformity

  1. Jan 14, 2017 #1
    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...
