Lincoln cautions that a recent measurement suggesting dark energy is decreasing is unconfirmed and should not yet be believed.
“there has been a recent measurement that suggests that dark energy is getting smaller. However, that is a new measurement, not confirmed”

Lincoln describes the quantum field theory prediction of vacuum energy as 10^120 times larger than the measured dark energy.
“that number is the rather embarrassing 10 to the 120 power times. That's a one with 120 zeros after it. bigger than the measurement of dark energy”
