Astynaxx you said quarks and leptons evolved into protons and neutrons, how is this so? Evolved?

Atoms evolved from quarks and leptons very early in the lifetime of the universe.
In the minuscule fractions of the first second after creation what was once a complete vacuum began to evolve into what we now know as the universe. In the very beginning there was nothing except for a plasma soup... the universe was tremendously hot as a result of particles of both matter and antimatter rushing apart in all directions...
As the universe expanded further, and thus cooled, common particles began to form. These particles are called baryons and include photons, neutrinos, electrons and quarks would become the building blocks of matter and life as we know it. During the baryon genesis period there were no recognizable heavy particles such as protons or neutrons because of the still intense heat. At this moment, there was only a quark soup...
After the universe had cooled to about 3000 billion degrees Kelvin, a radical transition began which has been likened to the phase transition of water turning to ice. Composite particles such as protons and neutrons, called hadrons, became the common state of matter after this transition. Still, no matter more complex could form at these temperatures. Although lighter particles, called leptons, also existed, they were prohibited from reacting with the hadrons to form more complex states of matter. These leptons, which include electrons, neutrinos and photons, would soon be able to join their hadron kin in a union that would define present-day common matter.
After about one to three minutes had passed since the creation of the universe, protons and neutrons began to react with each other to form deuterium, an isotope of hydrogen... Source

We have established that there has been evidence from Cephid Variables to suggest the rate at which the Universe is expanding is accelerating.
Overall, that would mean that the total energy throughout the Universe is increasing? Would that not mean that the mass of the Universe is also becoming greater?

Does it really move at superluminal speeds? Or is the space bent/folded then its travels across the shorter distance?
Is there naything you have read, that you could link, that shows the expansion is no relatvistic (whatever the word is )
While special relativity constrains objects in the universe from moving faster than the speed of light with respect to each other, there is no such theoretical constraint when space itself is expanding. It is thus possible for two very distant objects to be moving away from each other at greater than the speed of light (meaning that one cannot be observed from the other). The size of the observable universe could thus be smaller than the entire universe - Para. 2 of entry
When people say this, it usually means they misundertand evolutionary theory. Often, the misunderstanding is wilful.
