I have a question regarding time dilation within the frame work of special relativity. I'm sorry as I know that this forum is constantly receiving questions like this however I just cannot seem to find my answer. Anyways, the question is concerning the twin paradox. We know that the twin aboard the spaceship would experience time slower and therefore age in a less rapid manner than the twin who is on the Earth. I've also been told that both twins would view the other one's time slower than their own, and this is where I have difficulty understanding it. Let's call the twin on the spaceship Alice and the one on the Earth Bob to avoid confusion. If Alice was constantly viewing Bob, always seeing that Bob's time is passing slower and aging less, then how does it work that Alice would return home to find that Bob had actually aged faster? I'm only in high school and so I would greatly appreciate it if you could conceptually explain it rather than with mathematics. Thanks!
