It is really not that hard to understand if you did understand relativity doppler and time dilation.

Yes i did not state otherwise, i said *first was sent from 300 000* and *last was sent from 0.00...1* > The first, as the last bit is received by E at E's location, at 0 km.

Well what i really want is answers to my questions but it seem to be to *HARD* questions. Or maybe they are just challenging........ > L8r |
