Why can't we find any maps with the real gravity values?
I posted a chart (not a map) in an earlier post. Here it is again. These are absolute
observed gravity values at different latitudes (74 and 77).
You note straight away there is a massive difference. This then needs to be ‘corrected’ for latitude, on they hypothesis that the difference is explained by latitude.
You will object that it shouldn’t be corrected? OK, let’s see where that leads us.
[EDIT] Oh yes, and these aren't gravity values, but acceleration values. As I pointed out, this is what the instrument is reporting, independent of any theory about what it is measuring.
