A blown transformer can be replaced. No problem. 2000 blown transformers including the one that powers the transformer factory is a whole other matter. It would probably take years to get the system back up.
Lightning protection doesn't work as well as it seems. Lightning protection is based on short high voltage high current spikes that blow the transformer in a fraction of a second. The low voltage "fry a transformer in an hour" DC currents a CME would inject in the system are a different matter entirely. Sure, if the cable is decoupled on both ends the voltage will rise to above the lightning arrester's breakthrough voltage and just arc the energy away but that doesn't work if the cable is not decoupled. Currently decoupling the cables is a manual job that can not be done for all transformers in the country in the 3 days of heads up a CME gives us.
Solar flares aren't exactly FUD. A big CME that hits earth will take out the electrical grid on the side of the planet it hits. Problem is, it would be unaffordable to prepare for the energy that would dump into the net. The currents would be massive and unlike lightning strikes a higher placed cable isn't going to fix it. You'd need to do something like equipping all masts with a lightning arrester AND make it possible to physically short the in- and outputs for all transformers. Then the amount of igniting/exploding transformers might be manageable.
That once a year that snow covers the road and the cleanup crews haven't been fast enough so it actually stays there (instead of turning into salt water) we drive a lot slower. Slower means you don't have to see as far ahead because you have more time to respond. It means the regular headlights are more effective.
Apart from that, especially women don't feel comfortable going around in dark places where they perceive that there can be rapists hiding in the dark.
Instead they prefer to so be blinded by streetlights that they can't see the rapist hiding a few meters beside the light spot. People are counterproductive at times. Streetlight makes most of us feel safe, besides the simple fact that they decrease safety in most cases.
Correct me if I am wrong, but my limited knowledge of what happens tells me this: Probably, assuming the observer is infinitely strong and can survive the gravity shear and immense pressure of the black hole: From the observers POV the universe speeds up, until the surroundings (except for the black hole itself) become a bright light, because time dilation causes the cosmic background radiation to appear like visible light. Then the black hole evaporates due to Hawking radiation and the observer is free again. When checking an outside ("absolute") clock billions of years have passed but the observer only felt a relative short while. The observer never encountered anything that could be considered a black hole. Time dilation reached near infinite before it could get there. The observer did encounter a lot of mass, mass that was falling into the black hole, never reaching it because time dilation didn't allow it to reach anything. This mass has unknown properties. It is far denser than neutronium. It is still falling towards the core, only slowed down by time dilation. The star itself was torn apart way before the "visible cosmic background" part. It kept falling towards the black hole as part of that mass with unknown properties.
From the outside an object doesn't exactly fall into the event horizon. It falls towards it but slows down before it. The light reflected or emitted by the object gets redshifted to nothingness. The event horizon does grow to meet the object. Assuming the event horizon doesn't grow extremely fast the object will be invisible due to extreme redshift. Whether it is torn apart by gravity shear before that depends on the mass of the black hole and the strength of the object.
Air filtration, chemicals for narcose/desinfectant/pre and post op medicine, a couple of people busy, hospital heating. A sex change operation is quite expensive, even just energy wise. It may cost more to change from female to male than there can be saved. Especially since adding those parts may not change a woman from semi coldblooded to warmblooded.
Although, if every woman did that the energy consumption would dropping quite far in a hundred years.
Oh and GPP probably meant whenever reasonably possible.
If the xbox would have been standby anyway then it doesn't matter. It's even unwise to add an appleTV's standby to it since however little that may be it's fully wasted.
Well, you could end each conflict by lobbing a few ICBM's at the enemy. That'd stop them for sure.
These weapons are an alternative to lobbing nukes. A nicer alternative, something akin to the difference between removing a tumor with a scalpel or with a sledgehammer. Neither is fun for the tumor, but the surrounding tissue prefers the scalpel.
Decelerating it with a magnetic field isn't feasible. The current in the railgun does 2 things: 1. It makes a hell of a magnetic field 2. It runs through the projectile. That current undergoes a Lorentz force due to the magnetic field. The Lorentz force moves the projectile.
How are you going to induce that current in a projectile that is heading towards you? Without it the magnetic field will not influence the projectile.
And that is besides the technical challenges in making a magnetic field with enough strength to stop this while enveloping the entire ship.
I'd upgrade the goalkeeper, but I am Dutch so that was to be expected.
Depleted uranium has the tendency to ignite with air at 700 ÂC. It may be so that the compression heating from the speed exceeds that temperature. In that case the projectile may turn into a nice cloud of poisonous uranium oxide. On your ship.
In short: I'd advise a tungsten coating around the uranium if they go that way. The hull of the target ship will strip away the tungsten. The friction will make it exceed 700 ÂC. The scientists working on this probably already know that.
While oxygen is the most common oxidizing agent it is not the only one or even the strongest one. Oxidizing just bears a similar name because usually oxygen is the oxidizer. Chlorine is more powerful and fluorine is even stronger than that. Some nasty stuff like ClF3 will oxidize with the silicon in sand, expelling the oxygen.
Not only with oxygen. Chlorine and fluorine oxidize stuff way faster. That is why ClF3 is so much "fun". (burns sand, burns concrete, burns water, burns glass, burns workbenches, burns researchers, burns labs, burns buildings. All while emitting nasty fluorine based gasses like large quantities of HF. Fun stuff.)
While they only use a few data points that's more than most people use. Every experiment has a chance of incorrect results. The Mythbusters are not some kind of gods that do not suffer from that. If they find something to be impossible or improbable then that is only valid within their test parameters. They must choose narrow test parameters to prevent 3 hour shows that Discovery would not put on TV. However if they tested it and found it to be busted then it is improbable that it is not busted. If other data points (usually experience from the fans) indicate that their test was flawed then they are not above retesting with a new set of test parameters, a set that may cause the effect. The CD's is not the only case they had to revisit a myth. Neither is it the only case where their original results were wrong. While confusing, going back to a debated result and retesting it is a part of science. A very important part.
For getting the CD parts out of a drive: In a desktop, don't. Install a new one. It's to much hassle. In a laptop: Ask the supplier. If it is too expensive then I'd advise an external drive if that is acceptable. If both of these are not an option you can clean them with pincers and a lot of time. Just get a decent supply of painkillers to alleviate cramp from holding that d*mn pincers so long. Myself: nowadays I don't use optical media often enough to even have it in my system. Granted, the external drive works just fine in the extreme case that I need an optical disk, but I haven't even used that one for over a year.

1 km per day means the cargo will be highly irradiated by the Van Allen radiation belts.
Quite unsuitable for human transport.
1. This isn't the first test. Labtests have been done extensively.
2. It's 500 meters. Not miles. Not even 1 mile.

HID lamps should be illegal and the legislators who pushed for their legality should be arrested. Those damn things are dangerously blinding.
A tiny bit of electricity times 135.470 km of public roads is a lot of electricity.
(disclaimer: that doesn't mean it's a bad idea)

Often I find it fun to do that too. Poking holes in extreme statements I mean.
Anyone caught on the construction site will be shot for for trespassing in a secure location.
In that case I wouldn't want to be a construction worker there!

If stuff like forcefields are allowed then you should just give your ship a General Products hull.

That squared in "speed squared" is much of the fun.
Nah, the terrorist would attack during a new moon.
Luckily the shell rotates together with the planet. Although I can't imagine that that makes it easy.
