I am guessing this is an easy one to grasp, but I think I am missing something in my understanding of relativity.
Relativity suggests that as an object moves toward the speed of light, a greater amount of force is required to increase its velocity.
For this to be true, wouldn't it require the existence of absolute position?
For instance, when we say an object is approaching the speed of light, shouldn't this be relative to another inertial frame, such as an absolute inertial frame?
An apple is moving through space near the speed of light relative to the earth. If relativity is saying that a larger force (than predicted by Newtonian mechanics) is required to increase the velocity of the apple, then why wouldn't it be also be the case for a pear on Earth (who is also moving relative to the apple near the speed of light)?
