Quite an interesting article on researchers in Japan attempting to provide supporting evidence on how our physical reality could emerge from the Superstring Theory by using a supercomputer model. I would love to see science proving the concept of multiple dimensions, and hope this research gets published with positive feedback.

The mechanism that explains why our universe was born with 3 dimensions:
a 40-year-old puzzle of superstring theory solved by supercomputer
A group of three researchers from KEK, Shizuoka University and Osaka University has for the first time revealed the way our universe was born with 3 spatial dimensions from 10-dimensional superstring theory*1 in which spacetime has 9 spatial directions and 1 temporal direction.
This result was obtained by numerical simulation on a supercomputer.
In this study, the team established a method for calculating large matrices (in the IKKT matrix model*4), which represent the interactions of strings, and calculated how the 9-dimensional space changes with time. In the figure, the spatial extents in 9 directions are plotted against time.
If one goes far enough back in time, space is indeed extended in 9 directions, but then at some point only 3 of those directions start to expand rapidly. This result demonstrates, for the first time, that the 3-dimensional space that we are living in indeed emerges from the 9-dimensional space that superstring theory predicts.
