1 year later (scaled up model)

Apparently this is considered a "Lightcraft" and it's distinct from solar sails because it's dependent on the expansion of reaction mass to accelerate rather than being accelerated by light pressure alone.

not a lot of news on this, probably not a feasible project to "launch satellites into orbit within 10 years"

I really want to learn more about space, /sagan/ but the sheer vastness of the amount of information on the subject is just overwhelming to me. I could spend a lifetime just literally reading about space, different theories, the math involved with space and space travel, how stars work, if interdimensional travel is possible, astral planes... Just all of it. And to be honest it's very humbling but yet it puts things into perspective. We are less than a fraction than a blink of an eye in age to the universe, and we are beyond microscopic because the universe is so vast but yet, it would take millions of years to reach the farthest depths. Maybe I'm over-thinking this but space is just mystifying to me and there's so much to learn and I don't know where to start.

Plus you have to understand that we're on an exponential curve with our progress, not a linear. If it were linearly, it would be hundreds of years, at this rate a quantum AI will invent warp travel in less than 100. It won't even be invented by humans, it will be invented by a machine.

I recently read an article where some experimenters were able to entangle light with particles bound by the strong interaction, thereby creating a "ghost" strong force within the group of photons, which don't have color. I believe the researchers alluded that it was like a crystal made of light or something.

I don't really understand the process which by entanglement works, but I was wondering if this could have implications for neutrino astronomy?
Could neutrinos traveling through the detector be entangled with photons or the particles of some electrically charged medium in order to create measurable events and create an image?

Imige is the Super-Kamiokande neutrino telescope

What's this laser confirmation you're talking about? I'm not familiar with the terminology, though I can see how it's one possible way of providing a basis for comparison. Though, if you're gonna run a laser, just communicate via it in the first place.

The quantum uncertainty principle makes it impossible to measure both state and momentum simultaneously because bouncing a photon off a particle changes it's state or momentum (not sure which). The laser eliminates the need for 1 of those measurements.

The reason we don't use lasers is because they're limited to light speed. And radio waves, which travel at light speed, are already used to transmit information back to Earth. I believe a signal to mars takes 3 minutes, 6 for a round trip, not really useful for real-time controls. That's why Curiosity is mostly autonomous.

The problem with neutrino detectors in that the probability of interaction with matter is very low, so you don't detect many of them. Entangling them with photons wouldn't improve that. Entangling them also wouldn't give you any more information, I don't think you could actually entangle them without changing the neutrino destroying the information you want. We can already makes images with neutrinos it just takes a very long time due to low count rates.

So, I think it's possible that the cat is both both dead and alive. I think this is explained quite easily by the addition of time--it really doesn't matter. The experiment shows that the cat can exist in both it's living and dead states simultaneously because in one case, one outcome is possible, and in another, the same is true for the other. To an observer, therefore, the cat would both be dead, alive, and any combination or twist thereof. I see no problem with this. It's fascinating really, and illustrates pretty clearly that reality is a function of what can, and cannot happen. Things do, or do not. They also try, because we can imagine them trying. It's all quite beautiful and elegant really.

To an observer, they would observe the cat being alive for a short period of time until the geiger counter beeped and triggered a mechanism to kill the cat.

Real cats are made of too many particles to have such literal duality, and the definition of "alive" is just an assortment of many many different chemical interactions happening on the macro-scale.

The Schroedinger's Cat of the experiment is supposed to be representative of a single particle's quantum state, not an actual living cat.

I will preface an delusionally simple and effectively null hypothesis with a fact. This fact is that I am an idiot. Now that I have that out of the way I would like to propose an idea that's bounced in my head a couple times. It is in no way based in fact nor entirely complete logic. I just want to say something with no judgement so that I may allow the idea to be considered by intelligent individuals or at the very least a few stoners on the net.

Through the Copenhagen interpretation of quantum mechanics, the hypercondensed universe at the beginning of time could have been both stable and unstable. Out of that uncertainty one of two realities spurred this one into existence.

Not that I know anything about anything, but I had a few ideas to make getting into space easier, maybe, but probably not. The space elevator has a shitload of engineering challenges to surmount before it's workable. Materials challenges, construction challenges, hell even environmental challenges. Let's think outside the box.

Idea 1: We build a huge, elliptical track around the Earth that at it's nearest point passes within 75,000 feet of the highest peak (something like 100,000 feet above sea level). You take a plane to the track, load onto a spacecraft and away you go to the other end of the ellipse where you're more like 1 million feet from Earth.

Idea 2: Place a solar orbiting space station 100,000 feet outside of Earth's orbit (75,000 plus 25,000). Have the station travel just fast enough to avoid getting caught by Earth's gravity, and about once a year (or maybe not) the Earth and the station make a close pass during which cargo and passengers can be transferred from planes to the station. Rockets can then be launched from the station.

I'm sure these ideas are both bad. Very bad. The both pose engineering challenges that dwarf those of the space elevator. The important thing though is that we're thinking outside the box. What kind of bright ideas have you got?

>The biggest sunspot to grace the face of the sun in more than two decades just rotated out of Earth's view, but it was responsible for kicking up some truly amazing solar activity this week.

>The sunspot (called Active Region 12192 or AR 2192) shot off four powerful flares in four days recently, with many more smaller flares sprinkled in as well. The sunspot region was about the size of the planet Jupiter and is the largest solar flare observed in 24 years.

>AR 2192 was actually one of the biggest observed sunspots of all time, ranking 33rd largest of 32,908 active regions since 1874, according to NASA scientists C. Alex Young and Dean Pesnell. But how does a sunspot grow this big?

/SAGAN/ How long have we really been studying the cycles of the sun? How likely is it that some magnetic vortex that has been twisting into knots for the last several centuries will just let loose and shoot plasma or radioactivity into the rest of the solar system? haven't we really only collected data on the sun for like the last 100 years? 150 years tops? Isn't that just a blip in the life cylce of our star?

There are lots of anomalies in the sun's activity. I read somewhere that the sun's magnetic field is not acting according to projections, and in the last 25 years, that the sun's surface temperature has been much hotter than projected.

The sun has been observed regularly for 400 years. Sunspots come and go in months not years. The suns surface temperature is very constant.

Actually, the observation of sunspots goes back farther than most other modern astronomical data, predating telescopes. Thorough day to day records are probably only to be had for the last 100 years or so, but many interested astronomers in the last few centuries kept sketches of sunspot activity periodically.

weve been studying it since we began. it makes a pretty obvious thing to wonder about. weve been studying it scientifically since science began. with telescopes when telescopes began. not much else can lay the same claim to our attention historically. basically weve been keeping an eye on it so its unlikely to do something now that we havent seen in recorded history (with the tools available to us at those times) or from what weve seen in the geological record.
obviously the mayans didnt understand solar flares but if part of mexico had been zapped to a crisp in recent time im pretty sure wed have both historical mentions and physical proof.
