and what else?...well, iris might well have encountered 'bekenstein' and his 'black hole' theories....see previous post....go figure:

 

"In 2004, Bekenstein boosted Mordehai Milgrom's theory of Modified Newtonian Dynamics (MOND) by developing a relativistic version. It is known as TeVeS for Tensor/Vector/Scalar and it introduces three different fields in space time to replace the one gravitational field."

oh and if you are interested, McDonald....LOL....this is where the problem lies...remember your 'comma' in relation to mimecast?....anyway, I'd never use the following equation....too much 'error' involved....go figure:
