Is there anything in quantum fields that directly demand them to not be Lorentz invariant? I feel like these are independent hypotheses..

- pdonis 3y ago> Is there anything in quantum fields that directly demand them to not be Lorentz invariant? To be more precise, any quantum field state except the vacuum will not be Lorentz invariant. That's not something specific to quantum fields: any non-vacuum state in classical special relativity will also not be Lorentz invariant. It will look different in different frames. That's just an obvious consequence of things like length contraction, time dilation, the fact that the energy and momentum of an object are different in different frames, etc.
