#### Transcript of Simultaneity

Simultaneity
The concept of Simultaneity is reference frame dependent. What seems simultaneous in one frame is not simultaneous in another.
In working through these different reference frames it is good to draw a picture that is outside the frames in question. One that doesn't take any time for information to reach.
Try to determine in this outside frame what happened 'first' and let that be time = zero. Then run everything off of that time to figure out the course of events for other reference frames.
