Watching Star Talk.
Had some interesting questions/ideas - such as what makes you a scientist - they think its 100% curiosity but our education system damps that all important curiosity. 100% agree - but IMHO the more important thing is as Feynman says - the ability to doubt and constantly check from observation our current best beliefs (theories).
But one question really made me think. Do we know the why of gravity. The two astrophysicists there said - emphatically - NO - but we are working on it.
I went Hmmmm - not so sure. Isn't it space-time curvature and the principle of invarience. But is that why? In a sense, as I often say it's useless because if you know one why then you are faced with the why of that. But this is specifically gravity - is our current knowledge enough to give a yes or no answer - or - not really sure. What do others think? My answer is yes - but can be persuaded by others.
Thanks
Bill
