Simultaneous Events<br />
The judgment of simultaneous events is also a<br />
matter of relativity. Consider observer O T sitting on<br />
top of moving train while observer O E is on ground.<br />
A<br />
A T<br />
A E<br />
Not simultaneous<br />
O T<br />
O E<br />
Simultaneous<br />
B E<br />
B<br />
B T<br />
At t = 0, lightning<br />
strikes train and<br />
ground at A and B.<br />
Observer O E sees<br />
lightning events A E &<br />
B E as simultaneous.<br />
Observer O T says event B T occurs before event A T<br />
due to motion of train. Each observer is correct!
