Ask AI: Tom leaves on 1st Jan 2024, travels at 75% the speed of light, and returns to earth on 31st Dec 2024. How many earth years will he have aged?

Tom has made a trip at relativistic speeds where time slows down. According to Einstein's theory of relativity, traveling at the speed of light causes time to pass more slowly for you than for people who are standing still. This is known as time dilation. To answer the question, we need more information, such as the specific distance traveled. The time dilation depends on the velocity, sure, but also on the duration of said velocity. But if Tom experienced one earth year (from leaving on 1st Jan 2024 to returning on 31st Dec 2024), he would actually age less due to time dilation. We can calculate exactly how much using the time dilation formula: t' = t / sqrt(1-v^2/c^2) where: - t' is the dilated time (time experienced by Tom) - t is the proper time (time experienced on Earth) - v is the velocity of the moving object (Tom) - c is the speed of light However, his exact age after the trip could only be calculated with full information on his exact route and total traveling time.
