VIDEO: How to Unbox & Build The Universe

So, the universe just arrived at your doorstep…in a box. Now what? The two videos below show you what comes in the box and how to put it together.

Video 1 – In “Unboxing the Universe” the following cosmic components are revealed:

  • black holes
  • dark energy
  • dark matter
  • stars
  • dust, gas, and more!



Video 2 – In “How to Build the Universe” the cosmic components are pieced together into the universe as we know it:

  • Building a Galaxy: Start with a supermassive black hole at the center, populate the surrounding region with appropriate proportions of blue, red, yellow, and white stars, then spray in the dark matter.
  • Building the Universe: After building galaxies, arrange them into a cosmic web, then spray in dark energy and watch it grow!
