And physics is mathematics, correct?

[macromagnon]

From one perspective, mathematics is the study of the methods of reasoning on abstract concepts. Theorems follow from any set of axioms that do not lead to any contradiction. In physics, one is usually only interested in results relating to the current universe we live in. In that sense, mathematics can be viewed as more general.

For Tegmark, that's enough to argue reality is every possible universe of mathematics.

[solarengineer]

I thought physics is described by mathematics.

[goatlover]

If it's all physics, where does the math to describe it come from?

[GoblinSlayer]

From imagination.

[goatlover]

The physics imagines math to describe itself?

[GoblinSlayer]

Humans imagine math to describe physics.

Just applied linear algebra (or so claimed my professor of linear algebra...)
