South Korean physicists to simulate evolution of the Universe

The biggest mystery of the universe is our universe itself. When our technology has the power to build supercomputers, then of course we can aim to build a universe inside it. Some South Korean physicists have made a model of the universe on the powerful computer, Supercomputer. What made it interesting was even though these people were not astrophysicists; they still aimed at doing it. On 8th December, 2011 in Seoul, Juhan Kim and his colleagues at the Korea Institute for Advanced Study submitted their model of the universe, as published by arXiv preprint. This model was considered the largest till date made by any in the world.

Building the Universe Inside a Supercomputer

The model was named Horizon Run 3. The analysis included numerous calculations needed to be done as fast as possible. It had evaluated 374 billion dark matter particles. It represented two-third of the actual universe size that we observe. This model was about 8,000 times larger in scale than all previous models of universe submitted by researchers. The Supercomputer used to create this simulation was Tachyon II. This computer is the 26th fastest working in the world right now. Despite this computer being so powerful and with such high speed, it took 20 days to run the program!

For greater accuracy, large scale structures were created. The analysis is not yet over. Cosmos have dark matter structures. Some researchers had already developed its model. These were represented by cosmic web patterns. It was seen that the particles were arranged in a web pattern separated by tiny gaps and all connected to each other via filaments. The galaxy that we see was represented by halos, the dark matter. These were created on a large scale with filaments. These are not visible to naked eye. They can be detected only by the gravitational effect that it has on stars and dust present in the galaxies.

One must have studied in theories about the acoustic baryon oscillations. Well, this is the first time you can see them. According to arXiv blog written by KFC, these were the remaining particles of the waves in the plasma. The plasma that was existent during early times of the universe later froze at a place as the cooling took place gradually. Till date, creating the large scale structures of the acoustic baryon oscillations and the cold dark matter was next to impossible. The reason was simple; they did not have computers that could run such powerful programs.

But who knew there were still some heads working behind it day and night. The Juhan Kim and his team had indeed made it a reality. They are developing powerful tools. They are doing something that would help people get over the mysteries of our universe that have remained unanswered since its creation.
