Science upgrades

Suggestion for adding additional science: Having one tech for each major resource on each level of science. And maybe add a 7th or even higher tier of science for even greater returns for greater costs. So each level of science would have a wealth, land, science, joy, identity etc etc technology to research.

The less useful resources like joy and availability could be randomly sorted on each level of science, but the 3 most expensive ones should probably always be wealth, science and land, not necessarily in that order. Increasing those gives the ability to increase the rest through sheer volume of buildings after all.

Finally: maybe on the 6th level of science have an very expensive upgrade for truth production? Maybe even have it cost some permanent resource, like reducing lands from a system or two a little.
