Consider two guys A & B who are separated by a distance of 1 light hour (they are at rest to eachother)(adsbygoogle = window.adsbygoogle || []).push({});

Then A decides to fire a bullet at B. He took his gun and fires.

The bullet moves with a velocity of 90% speed of light (here the bullet is hypothetical therefore it moves at that speed at the instant it is fired)

The observer B calculates its time of arrival by using Distance/Speed therefore B predicts the bullet will reach when HIS CLOCK reads 1hr and 6 minutes.

I hope you don't have any doubt in this.

(IT IS CLEAR THAT BULLET HIT HIM WHEN IT RED 1HR & 6MTS ON B’s CLOCK )

Now imagine everything from the bullets point of view

Bullet thinks it is at rest and the whole system ’that its A & B’ is moving pass by. So the B guy will reach at bullet when Bullets clock read 1hr and 6mts.

Since moving objects slow down in time by relativity, bullet calculates the time of B to be slowed down

Therefore bullet uses his equation of time dilation and finds out that when B reached bullet, B’s clock will only read 26.15 minutes

I hope it is clear for you

(IT IS CLEAR THAT "B" HIT THE BULLET WHEN B’s CLOCK RED ONLY 26.15 MINUTES)

both the results does not match eachother, what is the solution of this paradox
