Why don't you feel older when traveling at the speed of light?

SUMMARY

The discussion centers on the twin paradox in the context of special relativity, specifically addressing why a twin traveling near the speed of light ages slower than their Earth-bound counterpart. When the traveling twin returns, they find their sibling significantly older due to time dilation effects experienced at relativistic speeds. The phenomenon occurs because, while the traveling twin perceives time normally during their journey, the passage of time for the stationary twin accelerates at a different rate. This discrepancy is a fundamental aspect of Einstein's theory of relativity.

PREREQUISITES
  • Understanding of Einstein's theory of special relativity
  • Knowledge of time dilation and its mathematical implications

According to the twin parodox scenario, when a twin goes in a rocketship and it travels near the speed of light and come back toearth with his now older twin brother at a speed far from the speed of light , his surroundings suddenly seems like they aged greatly , including his twin brother. While he was been traveling near the speed of light , his surroundings exactly appeared as it did as he departed from the Earth before his rocketship reached the speed of light . If his surroundings suddenly seemed liked they age as his rocketship slows down to the to a speed far away from the speed of light, why doesn't he age as well as his brother who was on Earth the whole time?
