[00:00:00]Did you know zero energy is forbidden by physics? In quantum field theory, every field has a ground [music] state, a lowest rung on the energy ladder.

[00:00:09]But that lowest rung is not zero. It carries what physicists call zero-point [music] energy, a residual hum that cannot be removed, cannot be cooled away, cannot be switched off.

[00:00:21]It is not a flaw in the theory. It is a feature of how quantum mechanics [music] works at its deepest level.

[00:00:27]The uncertainty principle itself forbids a field from being perfectly perfectly still. To be perfectly still would mean knowing both its value and its rate of change exactly. And that is precisely what the uncertainty [music] principle does not allow. So the field trembles, always, even in the coldest, emptiest corner of space, even in absolute zero, [music] even now.

[00:00:50]Scientists still use it as a quiet clue to the larger mystery. That small detail changes the scale of the whole story.

[00:00:58]The evidence
