Comparing running low on fuel to being low on charge s a flawed comparison. It takes less than10 minutes to completely refuel a car which will get you another 600 or so miles. It takes hours to fully recharge anelectric vehicle and even then, it has a fraction of the range. When you can get absolutely anywhere you want to be, as far away as you want to be, in a tesla or any electric vehicle, in about the same amount of time that you could cover that distance in a gasoline vehicle, range anxiety will vanish

You are presuming that much of range anxiety was ever alleged to be based on rational thinking to begin with. Of course, however irrational and based on emotion it might be, it is no less a reality, and still merits being addressed.

When you can go a thousand or.more miles in one day in an electric vehicle, whether that's on a single charge, or accomplished though rapid recharges that take only a few minutes each, at any of what should be ubiquitous recharge stations around the country, comparable to refuelling a car at a gas station, range anxiety will disappear.

Depends on the thickness of the sheet. If a sheet has thickness d, The maximum surface area of a sheet that fits in a box of volume V (assuming all side lengths are the same) is V^(1/3)/d *V^(2/3). If d is enough orders of magnitude smaller than the size of the box, the area can get to be quite large.

As soon as I saw the picture of it, I recognized it as being the same as one that I saw someone using at a campsite I was at in the 1990's. I don't recall the exact year, but I remember the guy saying that it chopped wood a lot easier when I asked about it (I didn't even recognize it as an axe until he used it, where every single blow split his target in only one swing).

Oh... and to answer your question.... sending a processor there may allow future generations to explore it remotely, but it won't enable them to actually live there. The best case scenario is that this world will remain habitable only for another couple of billion years or so. Finding more worlds to call home means that humanity could endure indefinitely (or at least until the universe itself dies, which nobody will be around to see anyways).

That would be "human made"... not "human". I was, in fact, suggesting that human beings *will* get there someday... just not in any person's lifetime today, barring something happening within the next millennium or so that wipes us all out here first. Such an event is not impossible, but it's also quite far from certain, since it is such a short time span on a cosmological scale.

The reality is that a continent-wide power disruption, which could easily follow a solar-generated EMP if our infrastructure is not hardened against it, will do hundreds of billions of dollars, if not trillions of dollars of damage to the economy., The east coast blackout of 2003 alone did about $10b worth of economic damage.... scale that up to the entire continent.

Even ignoring the threat of so-called deaths, the damage caused by a massive EMP blackout will easily measure in the hundreds of billions if not trillions of dollars for North America alone. The blackout on the east coast in 2003 alone created about $10b damage to the economy... scale that up to the entire continent.

A solar EMP could easily hit the entire US.

Of course, a solar EMP isn't likely to be big enough in localized intensity to do any damage to small things like aircraft.... but it could still damage the electric grid on the ground, which has wiring that is many miles in length and so exceptionally large voltages can be induced by such an event.

Except that those individual things wouldn't be tend to be affected by a solar generated EMP... A solar generated EMP isn't like an EMP weapon, which may do a lot of damage to only a very localized region. A solar EMP is ultimately only a threat to wiring that is on the order of multiple miles in length, such as the electric power grid. They are a threat to individual devices and appliances only to the same extent that they may be connected to a grid which is itself vulnerable.

My grandfather asked me to go golfing with him when I was about 7. There was some conversation among the adults concluding that, based on my age only, I was a hazard to the green and therefore would have to just watch. So I followed around old guys for an hour on grass that I was not worthy to putt on. I realize this is an antecdote. Fuck golf.

Your anecdote resonates with another experience I had as a youngster... I wasn't excluded from playing like you were, but my father's preoccupation with golf while I was growing up very nearly ruined my parent's marriage, and without me even realizing it at the time, created a psychological barrier that left a profound disliking for the game in general for many many years... he invited me to play with him a few times, but I never really enjoyed it. it would not be until I was in my early twenties when some peers invited me to go golfing with them that I finally realized what preconceptions about the game my subconscious had put there, based solely on my experiences I had while I was growing up.

Going back to your story, however, hopefully, you've matured enough since that time to realize that in your case, this was a problem with the alleged "adults" who decided you were a problem for their game than the sport itself.... if your grandfather had more character, he would have told those assholes that they were being arrogant pricks right then and there, and taken you somewhere else instead of just going along with their suggestion and making you sit on the sidelines.
