The world is everything that is the case.
1.1
The world is the totality of facts, not of things.
1.11
The world is determined by the facts, and by these being all the facts.
1.12
For the totality of facts determines both what is the case, and also all that is not the case.
1.13
The facts in logical space are the world.
1.2
The world divides into facts.
1.21
Any one can either be the case or not be the case, and everything else remain the same.

What is the case, the fact, is the existence of atomic facts.
2.01
An atomic fact is a combination of objects (entities, things).
2.011
It is essential to a thing that it can be a constituent part of an atomic fact.
2.012
In logic nothing is accidental: if a thing can occur in an atomic fact the possibility of that atomic fact must already be prejudged in the thing.
2.0121
It would, so to speak, appear as an accident, when to a thing that could exist alone on its own account, subsequently a state of affairs could be made to fit.
If things can occur in atomic facts, this possibility must already lie in them.
