Swampland Conjecture: String Theory & Unstable Universes

[Trollfaz]

WHat is swampland conjectures in string theory? I cannot find any online resources that can break it into laymen but as I watch Cumrun Vafa's presentations and its wikipedia description, they are string theories that are outside the landscape. So I am thinking that universes with Swampland conjectures cannot exist as they are unstable or make no sense.
