Recent experience about war teaches many things. (if war is what you <br>
mean by end of world, because there could be other reasons for end of <br>
world, like viruses, volcanos, metoerites and others).<br>
<br>
In an advanced war, the destruction of sats could appear relatively <br>
early. At that point, it would make not much sense to put many eggs up <br>
there on sats.<br>
<br>
In a controlled war, the sats might indeed be spared - maintained there <br>
in agreement, but then we wouldn't talk about 'end of the world'. <br>
However, it is not known whether there could be such thing as a <br>
'controlled war' when people get very upset at each other.<br>
<br>
For the contents of an 'end of the world' website, provided it could be <br>
reached somehow, maybe among some underground shelters, I'd suggest the <br>
following:<br>
<br>
- prayers (I am not a believer right now, but at the end of the world <br>
one never knows).<br>
<br>
- description of a means to measure time when light (Sun, starlight) is <br>
absent, so no shadows for sticks.<br>
<br>
- description of methods to communicate on a longer distance when <br>
electricity and batteries are unavailable.<br>
<br>
- other similar survival's expert advice.<br>
