WebbInflation is the proposition that the early universe contained at least a small patch that was filled with this peculiar repulsive-gravity material.† There are a variety of theories about how this might have happened, based on ideas ranging from chaotic initial conditions to the creation of the universe as a quantum tunneling event. WebbThe theory of inflationary multiverse is based on unification of inflationary cosmology, anthropic considerations, and par-ticle physics. Its most advanced versions include a combina-tion of eternal inflation and string theory into what is now called ‘string theory landscape’. This theory is still ‘work in
