Unfortunately, this sort of thing can't really be classed as space exploration
:\
Of course it can't. It was an industrial accident, like the people who died from radium poisoning making wristwatches.

They died because someone wanted to make a buck.
the good work of private spaceflight
Why is private spaceflight "good work"? I mean, it's good if you're a shareholder and you stand to profit, but where is the moral good in that?
Some of them become martyrs for the knowledge needed to achieve the goal.
No offense, but "the goal" was achieved decades ago. These people died for the profit of shareholders, not some "goal" of space flight which has been going on for half a century.
The guys (and woman) who died in Challenger were heroes. The casualties from this crash were like the people who died building the Empire State Building.
Facebook wanted to work out facebook*.onion, so they only had to sha-1 'facebook' and then store that state. After that, feed 40 sha-1 bits to the sha-1 function to generate a bunch of different hashes, keeping the ones that match.
That doesn't make any sense at all, if they can choose "facebook" I can choose "facebookcorewwwi" and feed it 0 bits to get my hash. It is the other way around, you must generate a public key and SHA-1 hash that, cut to 80 bits and convert to base32 and that'll be your service descriptor. Since each letter = 5 bits they basically brute force created 2^40 = public keys to find one that hashed to facebook*. There are tools for this, the estimate for a single 1.5 GHz processor choosing 8 letters is about ~25 days. Note that spoofing a full address would take millions of years the same way.
...OR it could just as easily mean we have a flawed math model. I tend to think the latter is significantly more likely...
Based on what? Modified newtonian dynamic models were effectively killed by the Bullet Cluster (and others like it). These colliding galaxies show that you have a gravitational field without ordinary matter present. If you try really hard you can squeeze MOND models into possibly explaining this effect but you make the models complex enough that they are vastly more complex than adding an, as yet undiscovered, particle. Indeed the last time we had a problem like this - the non-conservation of energy in beta decay - the solution was a missing particle and not a rewrite of the laws of physics.
A lot of physicists, including Neil deGrasse Tyson, have said that "Dark Matter" is actually a pretty poor name for the phenomenon because it's almost certainly not just some exotic form of matter
No clue who this Tyson guy is but either he, or you, have confused Dark Energy with Dark Matter. Physics is not determined by majority vote but I very strongly suspect that the numbers will come down massively in favour of Dark Matter being an exotic form of matter by which I mean some as yet undiscovered particle. Dark Matter is a very appropriate name for it since it almost certainly is matter and, lacking any electrical charge, will not interact with light at any wavelength. Attempts to explain Dark Matter by modifying newtonian mechanics are vastly more complicated and fine tuned than just adding an as yet unknown particle ever since the Bullet Cluster (and others like it) were discovered. While that is not proof that these models are wrong they fail Occam's Razor and, in general, solutions which fail this test turn out to be wrong which is why it is often used in science to select promising avenues for study.
Dark Energy on the other hand is definitely not a form of matter, for a start it is gravitationally repulsive, and is completely unknown. It is effectively Einstein's cosmological constant but when you use existing physics to try to predict this you end up with a constant 120 orders of magnitude (yes you read that correctly: 10^120) too large so it is safe to say that we are missing something here, even cosmologists worry about discrepancies that large!
That's all fair comment. The power of the Axis forces was, after all, rooted in the unity of feeling the various fascist groups instilled in their populations.
But it's a million miles from the modern myth of France just waving a white flag.
The bones found might have been from Amelia Earhart's body. When the measurements of the bones were looked at in 1998 was it noticed that they could have been Earhart's. Thankfully, the internet being what it is, everyone knows her body was found, and that this is an absolute, unquestionable fact.

No, it is not false. A proficient shooter with capable back stopping presents not even the slightests risk of stray bullets hitting anything other than what was intended.
So what happens is people make mistakes, get careless, or even distracted and bad things happen. Now here is your problem. It can be up to 21 days but does not need to be that long befor symptons show. When this happens, where will they be? In a crowded subway? Eating in a restaurant that might not clean the tables as well as they should? Will they be at a park where kids play? So what happens when one of these Ebola exposed people make a mistake, get careless, or dustracted and harms or kills someone else? The CDC says droplets from sneezing can spread Ebola, it also says it can survive several hours on door knobs and tables but several days in body fluids like blood.
So they wake at 6am, take thier temp twice a day (6am then 6pm) but starts with symtoms like feaver at noon while eating lunch at their favorite deli. They then go biking which also fatigues the body as most excercise does, stop by a park and rest on a bench, whipe the sweat from their forehead and then get a drink from the fountain. Now 6 hours has passed and you cannot in any way shape or form tell anyone how many people got infected, could have been infected, or unknowingly was infected and infects others.
According to the latest official figures, 43% of all statistics are totally worthless.
