I'm sorry I was late to the party, but at least I brought my own drink. I think it may seem strange to ask a lying machine about the hidden truths of the universe, but humanity has been doing that for millennia through shamans and that passion for knowledge seems normal to us.
Yet another claim of a propellantless space drive
- Thread starter martinbayer
- Start date
I think what Fleming actually said was: this is fun!
That's a good question. In my opinion, computers don't need to be smart to run trillions of simulations until we find the truth we need to know, using brute force trial and error. Nature needs billions of years to do the same thing by trying anything that works. A computer can do it in a few minutes, but the procedure is the same. The hard part will be interpreting the machine's answers: how to choose from trillions of options? That's why I said before that it will be necessary to create an interface that filters only the useful data. If it's done by a particularly sensitive human, their job is secured, but we'd be better off trying to automate the procedure.
It is possible that there are many honest people in the United States who still believe in the words of their president. Their patriotism is admirable and should not be questioned, but in the rest of the world it is not, a matter of perspective.Really???
Conspiracy theory - Wikipedia
en.wikipedia.org
I think President Lincoln still provided the most realistic assessment: "You can fool all the people some of the time, and some of the people all the time, but you cannot fool all the people all the time."
In Lincoln's time, politicians won votes thanks to the dissemination of their lofty ideals that guaranteed the honesty of their future government, now they limit themselves to paying for gigantic electoral propaganda campaigns aimed at people susceptible to social messages that are not at all subtle... Why would it be so?

Yeah, well, they're after the 'Swing Vote': Rest already convinced for/against, or would choose NOTA if that was an option...

( Set bar such 'enough' NOTA votes disqualify ballot's candidates for a decade: Long enough to perhaps acquire some humility ??)
Apologies for rant: Have been connecting new through-wall drain for laundry machine displaced from previous location by installation of new, wall-hung c/h combi-boiler. Which totally deranged gable-end of kitchen. Like Legendary guy who beat hydra into submission recursively, I swear Murphy threw me two new problems for every one I solved. Until nothing was left to go wrong with the plumbing.
Next, boxing-in pipes behind planned 'blind corner' kitchen unit, which will sorta-replace 'tallboy' cupboard lost to hanging said boiler...

Would you please explain and document "the dissemination of their lofty ideals that guaranteed the honesty of their future government"? There have been political frauds, cheats, and scoundrels since the beginning of recorded history - the only thing that has changed is the efficiency of (electronic) media used for (mis)information.
Political fraud? Are you seriously proposing some conspiracy theory? Are you suggesting that a dark force intervenes in the elections? I find it hard to believe that such dangerous ideas are freely put forward in this forum.

I guess the German and Spanish interpretations of the English language may differ(?), but I leave it up to you to count the instances of the word "fraud" in the above referenced Wikipedia article. I have to tell you though that your attempts at gaslighting are shall we say less than elegant.
Very good thing about the gas light. I think the biggest discrepancy between our thinking is what we expect from society. I'm not shocked by anything a politician does, one of my best friends makes a living writing speeches for them.

I'm not shocked anymore by anything a politician does or says either, I'm just surprised by your denial of an obvious fact. Are you perchance running for public office yourself, like oh say dog catcher (although I gotta say that must be a way easier job than cat catcher/herder)?
I've been in public office for thirty-five years, so I'm not surprised by anything people do. For some reason the animals trust me, it must be some pheromones, I would never hunt them. This conversation is very refreshing, but I think we should pretend we're talking about fuelless spacecraft to avoid getting kicked out of this thread.

As a fairly high(?) functioning social animal myself, I salute you for your service, Sir, and yes, let's talk about propellantless propulsion. At some point in this thread, especially when it came to fancy shmancy electrodynamic considerations, I was struck by the fact that the good old concept of the photon drive hasn't come up. As a youngster, I was (and, as a geezer, still am) utterly fascinated by the factoid that a simple flashlight (or "electric torch" for all you people of a British persuasion out there) might actually be a p**s poor space propulsion system.

Proof of what exactly? And what are hair shirts anyway?
Another project of religion---to help make your point

Hairshirts are garments made from rough animal hair (usually that of goats) worn as a top or under a shirt and against the skin so the coarse hair will rub and scratch the wearer.

Right - always slavishly follow graduate students, no matter if they riot on university grounds - there seems to be a lot of energy-momentum violations at high-energy levels going on right now...

Yep. Means we consider those power levels extremes, as opposed to some hypothetical life that lives inside stars, for example, that would consider most power levels under gigawatts to be low.
Light still has the power to amaze.
As it turns out, if you hit water at a forty five degree angle along the green spectrum, you can get evaporation without heat.
That didn't surprise me as much as today's article "Research team discovered new property of light" from work by UC Irvine's Dimitri Fish man..."photons can obtain substantial momentum, similar to that of electrons in solid materials."
From:
Research team discovers new property of light
A research team headed by chemists at the University of California, Irvine has discovered a previously unknown way in which light interacts with matter, a finding that could lead to improved solar power systems, light-emitting diodes, semiconductor lasers and other technological advancements.
A little more oomph for space drives?
He might be in driving distance of you Martin.
I do remember an old Space Daily article about one sail material getting an added bounce a decade or two back or so--that was silicon too IIRC.
Maybe this?
Ultra-thin sail could speed journey to other star systems
A tiny sail made of the thinnest material known – one carbon-atom-thick graphene – has passed initial tests designed to show that it could be a viable material to make solar sails for spacecraft.

Thank you for that---my "Google fu" is lacking (Dogpile used to be my go-to).
I figure building a massive laser for Starshot may not be needed if an in bound objects trajectory sunward could be flattened a bit---the way Sol eats comets, all you need are a lens between the laser and anything to be accelerated.
It doesn't have to be aimed...just having small craft lased forward as heliopause probes is fine---whatever works.
