Notebook :

Back to start cause this post isn't correct yet :
Energy is mass multiplied with it's heat divided by it's square spacetime lightspeed. (gateway : refractometry)
{S.I. unit = kgT/s²) {S.I. unit = { (kgK) / (m/s)²) }

• Wet van Snellius
• Correctionfactor for spacelightspeed should be
  
  Lightspeed remains the same , though distance is shorter so traveled path deviates and can't be compared as exactly the same !! That's why I add this correctionfactor {(n) multiplying with (c)} to get space-lightspeed.
  n has no S.I.- unit , so formula S.I.- unit formula remains (more or less) the same.
• {i.e. when light moves through Orion , it will be broken and energy of objects within Orion will differ from any other medium in space !!}
