Greene also points out : "Does Elvis exist right now? No....(Elvis) is not on my current time slice...not on my "current" list...(he) does not currently exist......reality embraces the past, present,future equally and the flow (of time) we envision ....is illusory...." (page 132) ???

Well,that IS Einstein's view, and that of physics in general....equations don't distinguish between past present and future....Greene also discusses how entropy affects the arrow of time...in about an other 30 pages or so....and all in all it requires a few readings to sort out the different perspectives...but I, for one, was still left with more questions than answers.

Wikipedia says:
...but defining time in a non-controversial manner applicable to all fields of study has consistently eluded the greatest scholars.

So don't be surprised if you are not entirely comfortable with descriptions from Greene... nobody REALLY understands what time is....

But his book is a favorite of mine...
