The most likely scenario is that the universe continues to accelerate until it reaches the speed of light. Once this happens, it reaches the cosmic speed limit, so yes it will stop accelerating. However, it will change the universe drastically. Galaxies close to each other will merge into super galaxies, and the far ones will eventually travel too far away to be seen. So to us in the mega milky way, it will appear like we are the only galaxy in the universe. This will continue until the rest of the energy burns out and the universe ends in a dark freeze.

Well on the bright side we probably don't have to worry about that for billions upon billions of years. Our solar system will be donefor long before then. I think in about 1 billion years, the Sun will be 10% more luminous, which means high temperatures on earth, so survival will be very difficult unless we use the 'tug' method (position an asteroid near earth to give it a tug each year) to pull earth further away from the sun so by the time it happens our distance will even that factor out. Then we have to worry about the sun going red giant a few billion years later. Hopefully we'll be really advanced by then and it will be a non issue. If not, we weren't worthy in the first place
A few hundred years of hard science has led us to where we are today. I can't even image another hundred, or even a thousand... what about millions? My head just exploded.
