"I always wondered if the Lorentz transformation contributed to cosmic inflation.  As the Big Bang decelerated, space seemingly expanded in all directions.  I could extend the logic further by asking if continued deceleration might give the appearance of dark energy by further expanding space."

The short answer is 'no'. The long answer is too long, I'm afraid, given that this is off-topic for us. It may help to know that cosmological solutions are normally done in something called the "cosmological rest frame". You take out the small local motions (local in the sense of cosmology!).
