Is happiness really beyond reach?!

Having noted the absence of happiness in human life, a group of scholars began to look for a way to attain this happiness.
They could put their hands on the core of happiness by means of physical laws, so that they could reach it by following such a set of laws
However...Can worldly scientific laws, however great they may be, control happiness, make it surrender to them, and allow itself to be harnessed by their reins?
Are they able to help people actually taste happiness, so that the earth will become a garden of paradise?
How great this achievement would be, if only they could do it
