Today we are blessed with two extraordinarily successful theories of physics. The first is Albert Einstein's general theory of relativity, which describes the large-scale behavior of matter in a curved spacetime. The second is quantum mechanics. This theory describes the properties and behavior of matter and radiation at their smallest scales.
But, while they are both highly successful, these two structures leave a lot of important questions unanswered. They are also based on two different interpretations of space and time, and are therefore fundamentally incompatible. We have two descriptions but, as far as we know, we've only ever had one universe. What we need is a quantum theory of gravity.
Approaches to formulating such a theory have primarily followed two paths. One leads to String Theory, which has for long been fashionable, and about which much has been written. But String Theory has become mired in problems. Combining clear discussions of both quantum theory and general relativity, this book offers one of the first efforts to explain the new quantum theory of space and time.

Lærte en hel del ting, til min samling oppe i hovedet, nu ved jeg foreksmpel hvor navnet LaMDA kommer fra, og hvad det betyder, hvis du ikke kender til LaMDA, er det Google's AI, som har fået alle algoritme generator, lagt ind, så at kalde LaMDA for 'Big Brother' som udtrykket siger, er det ikke en underdrivelse, rigtig god bog, men lige her og nu, år 2022, er de gået helt væk fra teorien omkring quantum fysisk, stadigvæk samme skabelon, men totale andre metoder bliver brugt i dag, år 2022, og de har allerede fundet ud af en hel masse, og lige en ting til, hvor er han dog forelsket i Einstein, og roser ham til skyerne, men undlader at fortælle om alle hans mange mange fejl, og hvor meget danske Niels Bohr egentlig bidraget med, der var en kamp mellem Einstein og Bohr, dog var det fra Einsteins side at der kom en teori som de ikke kunne slå den gang, men i dag, år 2022, værdiløst...
