General relativity and quantum field theory answer this question in very different ways. This collection of essays by physicists and philosophers looks at the problem of uniting these two most fundamental theories of our world, focusing on the nature of space and time within this new quantum framework, and the kind of metaphysical picture suggested by recent developments in physics and mathematics. This is a book that will inspire furtherphilosophical reflection on recent advances in modern physics. 606 $aQuantum gravity 606 $aPhysics 615 0$aQuantum gravity. 615 0$aPhysics. 676 $a530.143 700 $aRickles$01810439 701 $aRickles$b Dean$0792007 701 $aFrench$b Steven$053325 701 $aSaatsi$b Juha$01810440 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910957627903321 996 $aThe structural foundations of quantum gravity$94361770 997 $aUNINA
