*** Once again, that's incorrect. Large scale impacts produces a massive wave HEIGHT immediately surrounding the point of impact, but that wave quickly subsides. However, the VOLUME of water is the same, and thus, while a mid-ocean tsunami is barely noticeable in height, you've got a wave that's dozens of miles long and a thousand or more wide. When it approaches land, the wave rapidly compresses, going back to being very tall and not as deep. You're also mis-interpreting the Canary Islands issue: there, the problem is that the initial volume of water displaced is substantially less than a cubic kilometer, so the problem is that this volume is spread out over a large linear coastline by the time it reaches the USA. It's not the *distance* to the USA that's the issue, it's that the wave progagates through the entire Atlantic basin. In short, it's the "width" that has to be traveled, not the distance from origin, that impact wave volume when it hits a shore. It can still cause 10m high waves once it hits the beach, because wave height is a function of the offshore underwater geography as well as wave volume. For comparison, something like the 2004 Indonesian Tsunami displaced a bit more than 1 cubic km of water. An impact the size of Beiderman would display several DOZEN cubic km.

** Nuclear *surface* detonations would be virtually useless, especially in space. On Earth, a 1MT surface detonation causes a crater less than 100m deep, and maybe 300m or so across. Too much energy is expended in directions other than down into the earth. It's far less effective on a comet. There, the missiles would have no chance of "burrowing", and would just detonate on the surface, with no really effect. Remember that even the reduced Wolf has a mass of billions of tons (density of 1 ton/m3, and a volume of a dozen or more cubic km).

* Why does the President advise the people on the east coast to move away from the floodwaters when the comet hitting Montana is going to kill them all anyway?

** Because the comet is not going to kill them all instantly. Its that simple.

** Wolf was the older (and in some languages literally "bigger"). Hence it works that the larger piece gets the name of the elder astronomer.

* When Wolf-Biederman was split in two, why wasn't the far larger piece given the much longer name, instead of the opposite? It's only logical.

** Plus, it's not like landing the helicopters would have been a good idea. It's unlikely their crews were armed and thus able to deter a mob of scared people trying to escape certain death.

** There were soldiers all around the buses to keep the evacuation of the lottery-winners orderly, who were already leery of troublemakers trying to force their way on board. Who's to say the authorities hadn't already warned the chosen families that anyone who got violent would be tossed off the bus and left behind, no matter ''who'' they were?
