Why Does Time Dilation Not Apply When Rocket A's and Earth's Tails Meet?

Click For Summary
SUMMARY

The discussion centers on the relativistic effects observed when two rockets, A and B, approach each other at high speeds. When the noses of the rockets meet, the time recorded for the tails to meet, as observed from Earth, is denoted as T. It is established that the time dilation formula, \(\gamma T\), does not apply to the tails meeting because this scenario involves two separate events that do not occur at the same spatial location in the Earth frame. Thus, the time difference cannot be simply calculated using the time dilation formula applicable to a single moving clock.

Suppose two relativistic rockets A and B are headed towards each other. When the noses meet, rocket A and an earthbound observer set x=t=0. Let T be the time, relative to the earthbound observer, that the tails of the rockets meet. Why is it not the case that the time that the tails meet relative to rocket A is [tex]\gamma[/tex]T ?

That time dilation formula applies to a single moving clock. Do the two events (noses meet; tails meet) occur at the same position in the earthbound frame (and thus the time difference is recorded by a single earthbound clock)? Not necessarily.
