John Spacey

This book explains well the links between the notion of time at the level of a moving object (a planet for example) and the concepts of Dark Matter and Dark Energy.
I was very interested in these explanations and got answers, thanks to this book, to my questions on the complex subjects of Dark Matter and Dark Energy.
And it also allowed me to have answers to my questions on the possibility to bring together the Theory of Quantum Mechanics and the Theory of General Relativity.
