While traveling in a train at half the speed of light, you notice time slowing and distances shrinking outside. Your friend on the platform notices your clock ticking slower and the train appearing shorter. Both perspectives, based on relativity, reveal the dramatic effects of traveling at such high speeds, demonstrating time dilation and length contraction, which are central concepts in relativity theory.
