Simulating the First 80 Days of our Universe
In "Scientists Set to Change Face of Cosmology," the Korea Times writes that "a team of Korean scientists conducted the largest-ever simulation experiment to understand the evolution of the universe. The simulation, which involved 8.6 billion mass particles distributed just like after the Big Bang, took 4 years of computation.

But here, I'm confused. Last September, in "Simulating the Whole Universe," I mentioned another simulation done by the Virgo Consortium which used 10 billion mass points. The goals were different. The Virgo team wanted to simulate the entire life of our universe while the Korean team is trying to understand the evolution of the universe during its first 80 days.

Still, the Virgo simulation used more mass particles than the Korean one. Am I missing something here? Read more
and help me to understand why 8.6 billion is larger than 10 billion...
