Dinosaurs go AWOL... Astronauts in the NFZ (No Fly Zone ).

Firstly, I am trying to get into some trouble here by postingsome ideas that would show why Humans can not go into Space for very longperiods of time. We have two Vitamins that are very reactive to exposureto high energy sources. Vitamin A and Vitamin D.
Vitamin D, most peculiar of the two is relevant to bone resorptionand calcium metabolism problems in space. Astronauts take on a conditionthat is similar to Osteoporosis. The problem is not the condition of beingweightless with the lack of natural muscle reactions but the radiationinterfering with Vitamins A and D metabolism. The technology for radiationsheilding has to be in place, first.

Secondly, ( with reference to the KT extinction ) I believethat it could be proved that the extinction of the Dinosaurs was due toVitamin D HYPERCALCAEMIA. If theory holds that fungi and yeast existed250 million years ago then their sterol metabolism would be no differentthan today. The end sterol being ERGOSTEROL ( PROVITAMIN D2 ). If theoryholds that the atmsophere was a condition of subdued light, with littleULTRA VIOLET light ( thick OZONE LAYER ) penetration to the earth's surface,then there would have been a saturation condition of ERGOSTEROL under theskins of the creatures of this time period. ERGOSTEROL would make its wayup the food chain as an exogenous sterol . BANG ! A cataclismic event occursand partially wipes out the OZONE LAYER. The atmosphere slowly changeswith the event. Now ULTRA VIOLET is getting through to the earth's surface.A new chemistry is taking charge. They have existed for millionsof years without exsposure to ULTRA VIOLET light, then they get too much. A note to be made : If Dinosaurs had sterol metabolism then where is thePROVITAMIN D change to VITAMIN D if ULTRA VIOLET light does not penetratea thick OZONE LAYER. Is it possible that the creatures of this time periodhad PREFORMED VITAMIN D just like the fishes of todays fresh and salt waters? The evolution was from water to land ?

Would you have to exclude the present day VITAMIN D theory ?

Over a short period of time, if the dietary calcium intake remainedthe same the sudden high turn over of the ERGOSTEROL to VITAMIN D2 ( veryhigh end ULTRA VIOLET light exsposure ) and its metabolism would causeCALCIUM resorption and HYPERCALCAEMIA. Would this include toxic VITAMIND substances too ? Normal calcium metabolism would be disrupted. Main loadbearing bones would become fragile and break. If the turn over was reallyintense, internal organs would calcify. Over time, the shell thicknessof Dinosaur eggs would decrease to a point of fracture. Spinal column compaction and hip displacement. Immune system problems would beinitiated. Skin cancers. There would be varying degrees of survival but eventually,

Final extinction.
