From childhood I have been obsessed with space – not like I need my space, but like the great expanse of the universe. Fascinated by the Big Bang I attempted to replicate it in Mixed Reality with Microsofts Hololens system. Hololens attempts the incorporate virtual reality with augmented reality – it is basically a fancy see through Occulus, or a bigger version of googles one time wearable, Google glass. Using a gaming engine, multiple rendering tools and a Hololens, I attempted to recreate the big bang as an immersive experience.
The phases of the formation of the universe are represented in the immersive model of the big bang simulator:
- Planck Epoch (or Planck Era), from zero to approximately 10-43 seconds (1 Planck Time): At this point, the universe spans a region of only 10-35 meters (1 Planck Length), and has a temperature of over 1032°C.
- Grand Unification Epoch, from 10–43 seconds to 10–36 seconds:
The main forces of gravity break apart and first particles are created. - Hadron Epoch, from 10–6 seconds to 1 second:
The temperature of the universe cools to about a trillion degrees, cool enough to allow quarks to combine to form hadrons (like protons and neutrons). Lepton Epoch, from 1 second to 3 minutes - Photon Epoch (or Radiation Domination), from 3 minutes to 240,000 years:
During this long period of gradual cooling, the universe is filled with plasma, a hot, opaque soup of atomic nuclei and electrons. - Dark Age (or Dark Era), from 300,000 to 150 million years:
This period goes after the formation of the first atoms, before stars appeared. It was completely dark. - Star and Galaxy Formation, 300 – 500 million years onwards:
Stars and more bodies appear. Larger stars burn out quickly and explode in massive supernova events, their ashes going to form subsequent generations of stars. Large volumes of matter collapse to form galaxies and gravitational attraction pulls galaxies towards each other to form groups, clusters and superclusters. - Solar System Formation, 8.5 – 9 billion years:
Our Sun is a late-generation star, incorporating the debris from many generations of earlier stars, and it and the Solar System around it forms roughly 4.5 to 5 billion years ago, (8.5 to 9 billion years after the Big Bang).
The project is not available through microsoft, however hololens users may download and run the simulation using this link:

instructions for running the hololens simulator are included in the code and introduction.
