this is my understandig of the big bang
first, all the matter in the universe was confined into an extreamly dense ball, then as its entropy increased it exploded. the universe began expanding rapidly and as matter began to collide planets and stars began to form.
is this roughly correct?
i am in 10th grade and have never taken a physics corse so forgive me for my inaccuracies.

A very specific phenomenon called decoupling (specifically the decoupling of the strong force from the electroweak force) generated what amounted to a phase change in the nature of space-time. This drove a rapid superluminal expansion called "inflation" or The Big Bang. Look up inflation on wikipedia.
You are correct that the universe was expanding just because it was a hot dense ball, but that is only a small part of the story and does NOT explain the expansion we see today.

essencially yes, but look on wikipeadia. small fluxuations in energy density at the big bang are the reason why stars eventually formed. for the first (don't quote me on this) about 100000 yrs the universe was radiation dominated, in other words there was no matter. this was because the photons around were of such high energy they prevented atoms forming. for this reason we will never beable to see what happened at the big bang because there is nothing to see. then as this "primordal soup" (i think thats what they call it) cooled atoms formed and then as they grew by gravitation attraction they formed the first massive stars and galaxies that the present day stars and galaxies are made of.
i have no idea what 10th grade means but that should do

In the beginning, God created the singularity, and it was without form and void, and darkness filled the Universe. Then God said, "LET THERE BE A BIG BANG", and there was a Big Bang.

im in the eighth. but i am taking your level. but our simple definition is that it was a small point. then an explosion. and its been expanding ever since. so, for me, yes you have got it correct.
