Considering special relativity, let us take an object accelerating at a rate of 6m/s^2. Let's say that this object is large enough for an observer to securely stand on it while it is accelerating.(adsbygoogle = window.adsbygoogle || []).push({});

Would this object be able to accelerate at this rate forever without reaching the speed of light, and if so, what affects would the observer feel as the velocity reaches the speed of light?

Side question: Let's say a ball is held up 1m above the surface of this object, and is let go. Would the time the ball takes to reach the surface differ if the velocity of the object was at 25% the speed of light compared to 75% the speed of light?

Also, what would happen (if anything), if the object is travelling at a velocity of 299,792,457m/s (one less that the speed of light)?
