It’s hard to build models of inflation that don't lead to a multiverse. It’s not impossible, so I think there’s still certainly research that needs to be done. But most models of inflation do lead to a multiverse, and evidence for inflation will be pushing us in the direction of taking [the idea of a] multiverse seriously.

Interpretation

What this quote means

The quote discusses the challenges and implications of modeling inflation in cosmology, particularly how it often relates to the concept of a multiverse.

Alan Guth highlights the complexities involved in constructing models that explain cosmic inflation, suggesting that most of these models inherently suggest the existence of a multiverse. He acknowledges that while it's difficult to create models that do not lead to this concept, further research is necessary to deepen our understanding of inflation and the potential reality of multiple universes.

I can now state that I have succeeded in operating a motive device by means of [cosmic rays]. I will tell you in the most general way, the cosmic ray ionizes the air, setting free many charges - ions and electrons. These charges are captured in a condenser which is made to discharge through the circuit of the motor.
