Accurate observation but possibly wrong or inexact conclusions?

If you are following this theory (at least until the end) then we must enlarge our statement that big bang never happened.  What has bolstered the theory for sixty years or more?  

Firstly the so called expansion” of the universe based on the redshift of light, twice as far away, twice the redshift.  The idea being that space itself is expanding.  No problem, it seems, that as you read this, the volume of space created would amount to equal the existing (known to exist) universe many times over.  New forces etc have to be imagined in explanation.  There is no expansion of the universe, within galaxies or in systems closest to the milky way.  Why not? The expansion of the universe is supposed to occur everywhere. The microwave radiation detected in space from all directions by Penzias and Wilson, so carefully measured by them, but identified by another team and followers as a  “remnant of big bang”. Since we don’t’ think BB happened our view is that this is gravity plus radiation of electro-magnetic nature etc from space.  All of which waves space to some extent continuously.  Cavendish, possibly the most exacting of all experimenters, noted that objects in his experiment moved closer when suspended  and excluded all possibility of external influences.  Thus he concluded that the two objects  were attracted by gravity directly.  We suggest that the two objects pull space towards them in relation to their size and the space between them was pulled by both.  Thus creating the motion not an attraction.
