- How close to the Big Bang can modern particle accelerators get?
Main Question or Discussion Point
How many nanoseconds after the Big Bang was its energy density that achievable in modern particle accelerators?
No. Energy per particle and energy density are not the same thing. Baryon-Mev is a unit of energy per particle; it's just Boltzmann's constant times degrees C (or more precisely degrees K). Expressing temperature in units of energy per particle instead of degrees is common in physics.From fig.11 I see that temperature is given in baryon-Mev, which is a unit of energy, rather than degrees C. So they are different ways of expressing the same thing?
