Some weeks ago, after the death of Stephen Hawking om March 14th 2018 I looked at some of the general books written by Stephen Hawking. There was one of them that was written with Roger Penrose too and that was the way I got to know about Roger Penrose. I chose that book because I noticed that it contained equations and diagrams so it seemed to me more complete than other “basic” beautiful made books I had read by Hawking.
The truth is that during weeks I had tried to read the book but I almost got a headache each time I tried to read it. Sometimes I even wonder how on Earth Stephen Hawking could become so famous with such a difficult stuff.
Anyway finally I have looked at the book more carefully. Now I have the feeling I know a bit at least what was all about.
I leave you here with some vocabulary. If you get to know about this vocabulary maybe then you could read this book of both Hawking and Penrose with a more familiarity than me:
future frontier
Minkowsli space
Cauchy surface
global hyperbolicity
Raychaudhuri-Newman-Penrose equation
Einstein equation
weak energy equation
strong energy equation
singularity definition
theorems of singularity
Cauchy development
cosmic censorship

IP irreductible past
IF IRREDUCTIBLE FUTURE

Well, I do not know if these words may help you but when you read a difficult book I find nice that at least the words sound to me familiar … even if I do not understand them! it is a way to start for me.
Let me remind you that I also wrote about the book ROAD TO REALITY by ROGER PENROSE.
