Understanding Time Dilation and Velocity: Debunking Common Misconceptions

Click For Summary
SUMMARY

This discussion clarifies the relationship between time dilation and relative velocity as described by Einstein's theory of relativity. Participants emphasize that time dilation does not equate to a decrease in velocity for an observer; rather, it is a result of the relative motion between observers. The concept of gravitational time dilation is also addressed, distinguishing it from velocity-based time dilation. The conversation concludes that while an observer may perceive time differently, the actual velocity of an object remains unchanged regardless of time dilation effects.

PREREQUISITES
  • Understanding of Einstein's theory of relativity

Exactly. So if I am slowing down in time due to time dilation for observer, he will see my velocity slowing down.
I think you're mixing up the rate at which an object moves with the rate at which a clock ticks. You have a clock moving at a very high speed relative to an observer. The observer notices that the clock ticks slow (compared to a pair of well-separated clocks he has at rest relative to him) but that it moves with whatever that high speed was chosen to be. The fact that it ticks slow doesn't mean it moves slow.
