केशवसुत कसले मेले, केशवसुत गातची बसले ... माझी आई गेल्यावर सांत्वन करणारे शब्द...Roger Penrose

 सर रॉजर पेनरोज यांना नोबेल पुरस्कार मिळाला हे ऐकल्यावर खूप आनंद झाला कारण जानेवारी २००६ मध्ये माझी आई वारल्यावर त्यांचे वाचलेले शब्द मनावर सर्वात जास्त फुंकर मारून गेले... (डिसेंबर २ २००७ची माझी पोस्ट)

“…I think there is a positive side to this picture of space and time being laid out there as 4 dimensions, because it tells you that all times are there once and it can affect the way one thinks about people who have died.

I mean, I remember thinking in this kind of way when my mother died. In some sense she was still there because her existence is still out there in space/time although in our time she is not alive. A colleague of mine had a son who died in tragic circumstances and I presented this idea to him and it helped his understanding also.

This was before I heard that Einstein had a colleague died and he wrote to the man's wife that Bessa was still out there, and that somehow this was reassuring. I certainly think this way often, that space/time is laid out and that things in the past and things in the future are out there still…"

 "So this means that in a sense, the present past and future are out there, and that also gives us a very deterministic view of the world. We have no control of what happens in the future because its all laid out. I think the trouble that people have with this idea is that you think the future is under your control, to some degree, and so this means that if the future's laid out then in a sense its not under your control.

The question of the passage of time is something the scientists have rather set aside, and taking the view that its not really physics, it's a subjective issue; and subjective questions are not part of science. Now when you start talking about phenomena like one's own perception of the passage of time, then that is a subjective thing. And that's almost a taboo subject for science because it's subjective. The physical world at least according to Relativity, is out there, and there is no flow of time, it's just there; whereas our feeling (we have this feeling of the passage of time) are intimately connected to our perceptions."
