The problem of vacuum energy from a particle physics perspective

Recording Details

Scientific Areas: 
PIRSA Number: 


The problem of vacuum energy is reviewed. The observational evidence in favor of a non-zero cosmological constant is described. I then discuss several possible explanations for how a theoretically natural huge value of vacuum energy could be adjusted down to the unnaturally tiny but observed value.
