Deceleration is a matter of negative acceleration. An elastic 4-dimensional balloon of relativistic space-time, for my universe traveler I am always talking about, contracts the universe around him in his self-propelled, powered, constant of acceleration through the universe and expands the universe around him in his constant of deceleration toward his arrival at his destination. He, and all the rest of us, and just about everything else, are always positively accelerating in acceleration, or negatively accelerating in deceleration, in the universe (contracting it around us locally or expanding it around us locally as a matter of elastic 4-dimensional relativity (not 1-dimensional, but 4-dimensional!)).
If relativity is right, if the principle of uncertainty is right, if my universe traveler is right, if you are right whenever you travel, the universe cannot possibly be accelerating in expansion.... except from a 'local' (localized) spatial-time accelerating [deceleration] TOWARD SOMEWHERE, TOWARD A DESTINATION, FAR MORE LOCAL THAN THE UNIVERSE AT LARGE!
1. Elastic contraction of the universe around you, your accelerating [acceleration] of your local relative velocity in the universe. Including, possibly, your planet's, your solar system's, even your galaxy's, as possibly your vehicular instrument of accelerating acceleration.
2. Elastic expansion of the universe around you, your accelerating [deceleration] of your local relative velocity in the universe. Including, possibly, your planet's, your solar system's, even your galaxy's, as possibly your vehicular instrument of accelerating deceleration.
To you, the universe traveler (to all universe travelers no matter who, what, or where; no matter how slow or fast), the observation would, will, always be of the entire universe always accelerating in contracting (through your acceleration) or expanding (through your deceleration) around you. Now that's 'Relativity'.
