The point you drove home is well understood. 2. But the humans during all their wakeful hours could be wily-nelly thinking properly or improperly while a small fraction of world population would be engaged in research continue to think experiment thin again change perspectives and then visit Lab again and again till their hypothesis proved or disproved. 3. Eisenstein felt time expands universe expands one side and shrink on the other side simultaneously and time contracts or expands. These theories or hypothesis one by one after few decades proved. 4. Majority thinks only for themselves or for their families as to newer ways of making money increase income wealth or acquire newer or more families or adopt children ( as in Australia where grant subsidy ) despite having their own kids. 5. Newer way of thinking comes automatically only to a few for which basic education is a must. But exceptions are late Kamaraj Who when congress was in great dilemma and in chaotic state picked Nehru’s daughter Indira Gandhi for prime ministership. 6. I do hope, my view points above are not at tangent to the central idea of your post! Thanks and Regards.
