I think the idea is to give it a treatment analgous to how statistical mechanics works for properties of gas, for example. True, we can't easily say what individual atoms/molecules might do,…

The expansion of the Universe is irrelevant in this case. Our galaxy is gravitationally bound, so things (stars, planets, etc) within it do not follow Hubble's law. So there will be no modificati…

One option (if you have a trusted FPGA) is to run something from opencores.org, where you can verify the code. But more generally, yes there is an issue of having an initial base system which can be t…

I understand the point about software, but what about hardware? If the NSA is corrupting software, then it must be corrupting chips too. How can chips be verified NSA spy free? In principle, an anal…

One-time pads are probably what they meant to say instead of simply symmetric crypto. One-time pads are unbreakable, but the issue is transmitting the key to the recipient. Public-key crypo is so wide…

The activity level (in terms of how much material is falling into it) is fairly low, such that it doesn't qualify as being an "active galactic nucleus". However, a gas cloud (called "G2") will be pass…

The lines forming a cross in pictures of stars is a separate phenomenon. That is due to diffraction from the support structures of the secondary mirror. For a detailed answer to why the Einstein cross…
