comment Is a purely vertical or almost vertical orbital launch possible?
Heh - but what do you use to keep a 100 mile cable up? A 100 mile orbit is going to be pretty fast - it certainly isn't geostationary :-)

Have a look at physics.stackexchange.com/questions/26739/… for some useful information.

See the space elevator if you want a possible (nearly) solution to get to geostationary orbit (or twice that far-using matching earth to hub and hub to outer orbit cables)

comment X-ray diffraction (is it possible?)
Richard - how big is the crystal? Raindrop's answer covers small crystals, but the larger the crystal, the more difficult it is to analyse the data. Too big, and you just can't do it .

comment Are there still 'everyday' phenomena unexplained by Physics?
But the repeated predictions work for turbulent flow. We can calculate it. We know how to do it. That it is incredibly complex because there are so many interactions is self evident.

comment Are there still 'everyday' phenomena unexplained by Physics?
Surely many of these can be explained, but the challenge is simply that computation is complex.
