Comment Re:Where did get this idea (Score 2) 108

The problem is that keys used today are weak - and the ones used in the past even weaker.

In 2030 it will be trivial for a nation state to forge an email sent in 2020 that matches today's DKIM, and for a bedroom hacker to do it for an email sent in 2010.

Encryption that we tend to use is good enough for now - but not for 20 years time. In the 2032 election when Donald Jr is dukeing it out with Ocasio-Cortez, it will be easy for Russia, China, Nigeria, or probably even 4chan, to fake some SKIM signed emails from 2016 showing they actually planned to secretly take over the country in a Kang vs Kodos way.

But was it protected? Did they have lights or ladders or people just outside the 4:3 safe part which were cropped out in post? I believe that was a key reason TNG couldn't be done widescreen (sure you can recreate widescreen CGI, but while the actual film may have been available 16:9, it wasn't filmed 16:9 safe.

It's a survation poll, a reputable polling company. The questions asked, and the answers, are at https://ancillary-proxy.atarimworker.io?url=https%3A%2F%2Fokfn.org%2Fabout%2Fpress%2Fr... and the linked sheet

The only thing OKF had to do with it was setting the questions. Now that in itself can be very powerful (https://ancillary-proxy.atarimworker.io?url=https%3A%2F%2Fwww.youtube.com%2Fwatch%3Fv%3DG0ZZJXw4MTA), but here they didn't get the answers I think they wanted so if they were trying to rig the poll, they didn't do a very good job

Comment Re:Isn't the fuel used to move the craft? (Score 1) 163

Of course some would enter a lower orbit, the amount of energy needed to get them to LEO or start getting drag from the atmosphere from GEO is about 1.5km/s.

Sure, it would only need about 10-15m/s for some debris to get down to GEO from graveyard, but the risk is obviously less in graveyard than leaving it in GEO.

Parts accelerating towards or away from earth won't dramatically change it's apogee/perigee. Enough of a boom could cause it to intersect with GEO I guess, but I assume the graveyard orbit is high enough that that's a very low chance (i.e. parts wouldn't accelerate by more than 10m/s on an explosion)

If the explosion was big enough, in GEO or GTO, parts accelerating prograde could reach escape velocity (that would be enormous - 4-5km/s), parts accelerating retrograde could reach LEO or atmosphere (1.5km/s). the chance of a part getting the right amount of deltaV in the retrograde direction to put its perigee in LEO, but not impact the atmosphere to burn up in a few days, is pretty low, and pretty much the same whether it's in GEO or a graveyard orbit.
