This is not true. Because whatever your personal motivations, the mathematical result of you not voting is that you are voting for whatever majority comes out in the end. And because only a minority voted against Donald Trump, a majority either voted directly for him or was ready to accept his election win.

Comment Mars is still the goal (Score 1) 73

The Moon is target practice. We need to get away from innovative bespoke engineering, into industrial mass production with continuous improvement. To do that we need to fly often. Mars just doesn't have the launch window availability. The biggest part of the challenge is that we were born in the bottom of a deep well. To toss enough stuff out of the well for a long journey is critical. Boosters that reliably fly on time often and cheaply enough to get ships and fuel out of the well. Ships that carry fuel into orbit and return over and over since the vast majority of the material we need to send out of the well isn't payloads or ships, it's fuel. Kilotons of fuel. Once the factories and processes are set up for that going far beyond the Moon is fairly easy. But with a narrow opportunity every two years that's not going to happen in a human lifespan. It's not enough refinement cycles per year.

I see this accelerating the Mars objective, not deferring it.

It definitely didn't originally mean "government approved"

That is exactly what it meant. Regulation (from Latin rex = king) means: per the King's law. Or as Wiktionary has it: Borrowed from Latin regulatus, perfect passive participle of regul (“to direct, rule, regulate”) (see -ate (verb-forming suffix)), from regula (“rule”), from reg (“to keep straight, direct, govern, rule”).

You can do the calculations yourself. To break apart, a rotating object has to reach its escape velocity at its outer perimeter. Otherwise, the gravity would pull back anything that was trying to break apart. A black hole by definition has all its mass within its event horizon, and the event horizon is defined as the surfaces where the escape velocity equals the speed of light. That means that a black hole would have to rotate so fast that its equator surpasses the speed of light to break apart.

Submission + - Transporting antimatter on a truck is tricky ...

Qbertino writes: ... but the CERN Project "Antimatter in motion" just did it. For the first time in history researchers at CERN have transported 92 antiprotons on a truck in a specially designed magnetic enclosure. The test-drive went so well that the researchers spontaneously decided to go another round. One hard pothole could cause the antiprotons to exit their magnetic enclosure and be destroyed. The purpose of the experiment was to test the feasibility of transporting antimatter to other facilities in Europe to conduct further antimatter research. German news Tagesschau has a nice report.

Nebulously talking about known problems without naming them just shows you don't know the problems or won't enumerate them in fear of sounding ridiculous.

If I have my own source of electricity not relying on the grid, then that is my decision. If it makes business sense, why should I forego it? If it satisfies me as a hobby project, why should I abandon it? If the utility wants to pay me for my leftover electricity, why not sell it to the utility? This is none of your concern.

And the alleged problems for bird life are about the same than each single tree on the landscape. Yes, birds sometimes hit trees, because either they have misjudged their trajectory from the start (birds can be clumsy too), or because a sudden gust of wind blew them away. I sometimes find birds knocked unconsciously on our terrace, because they flew against the wall. Shit happens. To make this a problem of wind turbines is just arbitrarily and selectively projecting blame.
