I’m wondering about the “infinite density” part of big bang theory and whether “infinite density” is a literal singularity of everything or just a super duper high and immeasurable density or maybe something else?
In: Physics
There are hypothetical models of inflation that don’t require infinite density to work. The universe we know today could have been created by a field with a positive vacuum energy losing most of its energy as it expanded. This would slow expansion to close to what we see today and that energy would create particles that become the particles in our universe. The Higgs field is an example of a field with a positive vacuum energy.
