In your wiki it says, that the earth is accelerating upwards with 9.81m/s². But the problem with this is that after about 1 year, the earth would have accelerated to the speed of light. In the article it said that it won't accelerate anymore when it reaches the speed of light, but rather have a constant velocity.
This wouldn't be possible, because as we all know, things accelerate when falling down, so in this concept the earth would still have to accelerate. If it would rise with constant speed, then falling objects wouldn't fall, but levitate, until the friction of air is superior and decreases the velocity of the object. Only with a constant rising earth objects could fall faster and faster.
So the concept of UA can't work and hence gravity must exist.
