hi .. i don't understand in the twin paradox and in general and special relativity why time changes if speed changes
thank you
thank you
The "Twin Paradox" is a thought experiment in physics that explores the concept of time dilation in the theory of relativity. It involves two identical twins, one who stays on Earth and one who travels through space at high speeds. When the traveling twin returns, they have experienced less time compared to the twin on Earth, resulting in a difference in their ages.
Time dilation occurs in the Twin Paradox due to the effects of velocity on time. According to the theory of relativity, time slows down for an object that is moving at high speeds. This means that the traveling twin experiences time at a slower rate than the twin on Earth, resulting in a difference in their ages when they reunite.
The Twin Paradox is considered paradoxical because it challenges our common-sense understanding of time. In the paradox, the traveling twin appears to experience less time, but according to their own perspective, they are experiencing time normally. Therefore, it seems paradoxical that two events (the twins' ages) can be both equal and unequal at the same time.
Yes, the Twin Paradox has been observed in real life through experiments with high-speed particles. For example, muons, which are subatomic particles, have a short half-life but can travel at near the speed of light. When they do, they experience time dilation, and their lifespan appears to be extended from our perspective on Earth.
The Twin Paradox is a thought experiment that demonstrates one of the key principles of the theory of relativity - time dilation. This theory states that time is not absolute, but is relative to the observer's frame of reference. The Twin Paradox shows how time can be perceived differently for two observers in different frames of reference, which is a fundamental concept in the theory of relativity.
