flip flop .. great man .. That was a good discussion .. but people were lacking technical discussion ... We need some thing like 'PaulMaurice" discussion above. so I think . we are like a small insect in the middle of pacific ocean .. it does not know the size of water and does not know what is beyond the water?. It cant travel. coz it can live for few days and just wonders ..is there anything beyond the water? As the discussion above .. I feel ..human life is really really a short life .. as compare to the huge universe we have.
