  B) For low speeds, the theory predicts effects that are so small that they cannot be noticed without extremely precise, high-tech measurement.
  C) The theory is valid only at speeds close to the speed of light.
  D) The theory tells us that there is no such thing as absolute time or space, because measurements of time and space depend on your reference frame.
