"In 2006, a controversial paper on Heim theory theorized that it may
be possible to travel faster than light by using magnetic fields to
enter a higher-dimensional space.[16] However, due to the many
unproven assumptions in the paper, there have been few serious
attempts to conduct further experiments."
As you'll recall, travelling through the Soup requires magnetic
monopoles, which have been identified in the wild. Combining Heim with
Monopoles makes Branespace more realistic...
