Tachyon, an imaginary number field as super light speed.
Update:
fig.7.0 is "Twister" where space-time arises from spin (not spin arises from space-time). R. Penrose invented/discovered Twister. The drawing has been done with not Maxima but Gnuplot.
I downloaded Gnuplot from below link, very famous site, but I'm not sure yet this is the official site.
https://sourceforge.net/projects/gnuplot/
I begin to practice phenomena the symbol method with using Maxima and Gnuplot.
