@ericweinstein Behind both of these obstacles is a lack of imagination, an unwillingness to take risks and a mindset that the future will only get worse so why even bother. Dare to dream with eyes open and make the dreams real!

So one fun thing sci-fi fans like to talk about a lot is antimatter (specifically antiprotons) production for starships. The fun part is that we already make antimatter right now! But to get enough antimatter for any uses, we need to do a LOT better. 1/17

This is a very cool concept from a friend of mine. Using some clever tricks to make focused electron beams for powering interstellar spacecraft. It works over much greater distances than lasers, so the beam doesn't need as much power because you can accelerate for a longer time
Gerrit Bruhaug@GBruhaug

The latest paper that @JeffGreason and I wrote is out (in preprint)! This was a real fun one about using electron beams to send power for interstellar propulsion. Not something normally considered due to space charge but a couple tricks come into play… 🧵1/12

@TubeTimeUS Summer job all through college including grad school was repairing these things. The fix/repair anything attitude came in very handy throughout my professional career.

A human being should be able to change a diaper, plan an invasion, butcher a hog, conn a ship, design a building, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take orders, give orders, cooperate, act alone, solve equations, analyze a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, die gallantly. Specialization is for insects. ― Robert A. Heinlein

@jfreewright When I was in elementary school back in the 60’s there were playground arguments where wrong ideas were defended with “America is a free country!” I think some of them held onto that for life.

Isaac Asimov - 44 years ago. Never gets old, it seems. “There is a cult of ignorance in the United States, and there has always been. The strain of anti-intellectualism has been a constant thread winding its way through our political and cultural life, nurtured by the false notion that democracy means that 'my ignorance is just as good as your knowledge.'” aphelis.net/wp-content/upl…

@peterrhague This is the value of research consortia. Joint funding by industry and government that focus R&D on long term pre-competitive activities. Bulk of spending looks ahead 5-15 years with some funds allocated to more long term speculative ideas. Tax incentives for R&D help.

Let me be slightly indelicate; Musk assigns no resources to what you refer to as post-Einstein physics because he realises it’s almost certainly bollocks. You can juggle tensors all you like, but without predictions and experiments that’s just maths, not physics. Musk wants results, not to fund endless academic theorising about warp drives. Chemical rockets work just fine for colonising the solar system, the solar system is amenable to colonisation, and that is plenty of risk reduction (not that this is the main reason for doing it). We can worry about interstellar much later.
Eric Weinstein@ericweinstein

Long digression ahead. Please skip if not generally interested in interplanetary/interstellar issues. ----- We should hold a competition: who can figure out how to best make this argument and not sound crazy to the general public? If I were to try to steelman what I find odd about Musk's position, I would say that anyone this smart is tempted to use Mars and Rockets to make "Interplanetary" *not* sound like "Interstellar". Perhaps I have been uncharitable if this is the case. It seemed self-evident to my mind that anyone smart enough to be able to see the necessity of moving to interplaentary objectives would gamble mostly on post-Einsteinian physics and not rockets as the Moon and Mars are totally inadequate to diversify our risk and that rockets get us little else. But maybe the issue is that Musk truly understands people and that he has found the best argument to make interplanetary not sound insane. I admit, that I never considered that the point of SpaceX is a gateway to getting normal people to dream about what I have termed "restoring an indefinite human future" which was lost due to thermonuclear innovations of the 1950s. If humans were rational, a "go for broke" emphasis on finding the theory or theories beyond General Relativity would be our top priority. But somehow this apparently makes no sense to ordinary people who cannot contemplate that the speed of light may not be the last word in a larger theory that contains GR as an effective limit in the sense of field theory. I listened to this and wondered: is it simply so hard to imagine interplanetary human life as a top funding priority for ordinary people, that Musk has worked backwards from people and not forward from 'interstellar'? After all, his idea of making dorky electric cars cool by emphasizing speed was more about people's cognitive distortions around making EV not sound like golf carts or boring battery specifications. The thing I never understood was Musk's own zero allocation to post-Einsteinian physics. The best I can figure under this rubric is that someone could believe that the optimal research strategy is to first make make planetary diversification to avoid extinction sound as normal as possible. Mars already sounds crazy and he is clearly struggling here to make the world's most important point. Sorry to bother many of you with this digression. But I was just touched by how hard it was for him obviously struggling to find any way possible to make such an important point seem sensible. If I have gotten him wrong on this point, then I understand better why he avoids interstellar post-einsteinian physics. Said differently, perhaps he has figured out that man's first priority is convincing his fellow man that the only sane strategy for long term human survival through diversification is to make the sane goal of interstellar diversification not sound crazy to the people at scale. Maybe I was wrong. Maybe this is a difference in strategies and that "Occupy Mars" is syntatic sugar for ordinary humans who cannot contemplate interstellar diversification outside of a movie theater. If so, I understand where the difference in emphasis lies. I may still disagree given my perception of the urgency, but I never considered the idea before seeing this clip. Which, under any circumstance, was my mistake.

@tsarnick There are dreams and ambitions beyond what our minds can comprehend. We strive to do so and by reaching out, grasp them to make them real. The stars are only the beginning.

Rewatched Beneath the Planet of the Apes for the first time in over 20 years today. Forgot it’s the most insane movie ever made. Heston destroys the world, the way it should go out. I could not stop laughing at the voiceover. The end. That’s it. Lights out.

@ElieNYC It was an annual ritual when driving my kids to summer camp to play MPATHG on a little portable DVD player. All under 40. One went to see John Cleese recently on his farewell tour.

Question: If I write "strange women lying in ponds is no basis for a system of government"... does anybody under 40 know what I'm talking about? Do I have to cite it lest someone thinks I made that up myself? Should I just give up because I am old and need to be put in a home?
