The Third Quantization: To Tunnel or Not to Tunnel?

The Third Quantization: To Tunnel or Not to Tunnel?

Within the framework of the third quantization, we consider the possibility that an initially recollapsing baby universe can enter a stage of near de Sitter inflation by tunnelling through a Euclidean wormhole that connects the recollapsing and inflationary geometries. We present the solutions for t...
