Early Universe t=500. Mass is Looped Space
The Universe is made up of Nodes and Connections. This is what we call Space. The change of Nodes+Connections we call Time (Time=Change) ... As there is only Space, Mass must be made of Space. Mass is a (local) configuration of Space nodes+connections ...
Starting from Nothing the big question is what 'rule' defines the creation of nodes and connections. Is there addition of nodes? Or is it based on splitting nodes. Do nodes merge? Or can they disappear? ... and how are these nodes connected?
This requires very deep thinking and a careful approach. Nothing can be 'introduced'. Everything has to follow from and be accounted for by pure logic by starting with Nothing. The fact that Nothing cannot Exist and (therefor) Everything has to Exist (with change being time) is the first step and sets the example that it can be done. Creating Everything from Nothing can be done by pure logic.

PS: You might wonder about (the place of) God in all this. Well God simply is Nothing
