I've thought about the beacon idea for awhile and I built one for atmospheric experiments, not for the ISS or anything else, but having built one using LED's and blue laser diodes to see the performance myself, I now think the best way to do that is probably by using as high a power single mode laser diode as you can get, and then expanding the beam as wide as you can and shooting that into a mirror which sweeps the entire sky, now that's a big job. One problem with this is if in the visible wavelengths you will bring attention you don't want, or perhaps cause a problem for a pilot which is a crime in the U.S., even if an accident we can end up with fines or jail time here. Also, due to the beam being expanded, beyond that of the size of a galvo mirror used for light shows to get lowest divergence, you would need to make your own mirror scanner, that isn't so difficult and you could build a large mirror which turns fairly slowly compared to a light show galvo mirror, but it wouldn't be too difficult to get a decent speed.

The above idea is probably too extreme, for a simple beacon good for a hand full of miles, you can use single mode laser diodes and light show galvo mirrors and controllers, then everything is off the shelf but they are made for the visible wavelength and even if low power single mode, invisible infrared lasers are dangerous and can blind too, hooking that up to a galvo mirror has hazards too. Although if the power is low enough and the beam is put into a line generating lens, then maybe you are OK at IR, as long as everything is up high and there is no way a failure could cause the beam to sweep down to hit someone on the ground.

Simplicity is probably the best idea, just build a pointer using a single mode laser diode, expand it to just a couple inches and collimate to infinity focus, then use a large diameter plano convex cylinder lens to produce a line and scan manually. It could be a poor mans beacon. Using a fix beacon isn't going to be nearly as bright in the distance, but you could do that with 100 watt LED's, then no scanning, no muss and no problem for aircraft..

FYI guys, we have a troll here who has been in the forum for years, I half suspect this is that same guy because he is asking questions I have asked, identical to my own over the years. Need Distance, if you are legit, apologies, but this is really coincidental. Still, I am offering my thinking on this kind of thing because I know more than one individual is interested in atmospheric communication. Regarding UFO's and all that, I have no doubts EBE's are out there somewhere, maybe local?

If anyone who comes across this thread are trying to hook up with one of them, good luck, probably a very difficult thing to make happen and... are you sure you want to do that? I am not so sure you aren't risking yourself. I've seen craft which could be ours, or could be from some other place, I don't know.... at one time I thought I did, but when I examine the issue, the truth is I don't know what I saw, just know it wasn't conventional. My hope is such things can happen, but if it did, would all of them be good? I don't know.

Be careful of the doors you open up. Things are not always what they pretend to be. Stay safe :)

Thank you for the concern, BobMc. I know I'm taking a big risk here with my safety and even sanity but I need to know. At this stage of my life, I'm surious if there is any real 'magical' things out there or is it all just 'balls'. The only 'magic' I have ever experienced has been ufo sightings and psychic experiences. I'm not gullible or New Age - I have expereinced these things and it's about time I found out what they're all about.
On a positive note, after all my sightings, not one bad thing has happened to me. Their 'shyness' suggests that they are more after of me than I am of them.

The more I know, the more I see truth is stranger than fiction, FAR stranger! I wonder about all of those things myself, have for many years. I'm not new age either, I'm more science oriented, at least, in my mind but I am sure to some my mind is so far open to possibilities, it's a wonder my brains haven't fallen out, but I like it that way.

Hi Alaskan,

Again, thanks so much for your great input. You are answering all the questions I have and adding more questions to them.
Your idea on the poor man's laser may be the one for me because I believe that EBE could pick up on signals which we couldn't, especially lasers, which they would be ery interested in, I presume.

It is very strange the you have had all the same questions that I have, but that doesn't mean I'm a troll. If I was a troll, surely I wouldn't be answering every post here in such a thorough and polite, respectful way. So, I am not your Troll. Either it is coincidence or, dare i say, meant for a reason (which i don't really believe in that ultra-positivity). I could prove that I'm not a troll in a number of ways - I could pm you personal contact details such as email and even phone and you could speak with me in person. I hate trolls and the sneering social media culture so I can truly assure you that I am not one and that I get no pleasure from insulting or confusing someone else.

Which leads on to contact. EBE are most likely to be 'enlightened' because if they have come so far then they must be ancient and species like EBE and humans either become more enlightened or become extinct (nuclear war etc). Look up 'Issac Arthur' on youtube, search with 'Crazy Aliens. He has brilliant docs on the subject. Better still, join my facebook group to prove my identity and also my legitimate interest in the whole topic

I answered another post above about the possilbe threats in my inquiry but I am ready to face them and take whatever comes ...

I like it that way, too.
For example, I was born a Christian, became an Atheist at 17 and then became an Agnostic, due to ufo and psychic experiences, so I too am open to ALL possibilities. But I am very rational, too. I am the first to ask, 'could it be a meteor?' It has been friends with me who said 'a meteor doesn't change direction' ...

OK, I'm well known for jumping at any possibility of being trolled, many times in error, ask anyone around here, but too many times we have been. OK, I'm on track, with that comment I believe you. I'd love it if we had EBE's coming to the earth, as long as they didn't bring a book titled How to Serve Man with them :p

I believe the human species could use someone smarter, or who have matured as a race to help guide us along, we are too self-destructive as a species, clearly that is the case, has been throughout recorded history. My thought on this is we could use help, perhaps we need to come to the point where we can manipulate our own genes a bit to be less cut throat, only problem with that idea is it might leave us defenceless as a species, if were were too happy loving. Maybe we just need more time to mature and will do fine as we are someday, I do believe we are a more gentle race than we used to be, but our weapons are too powerfully and widely destructive now, too many of them too. Some idgits could destroy the planet getting into a nuclear war.

My main interest lately has been in the implications of the quantum double slit experiment, to me, it shows that consciousness is the ground reality, not matter. That and that in truth we are all a part of the same thing, all connected, all one being living as individuals, if that makes any sense at all. I have a reason for thinking this way more than studying quantum (at least, the woo woo side of it). One night I had a very unusual dream which seemed more real than waking reality, what I saw blew me away, I was near atheist, agnostic at best, now not... but I still have little patience for organised religion today, I should have more, but I don't.

Hi Alaskan,

CAn you please check my facebook group and friend me (I'm the admin)? My name on facebook, John Smythe, is fake because I prefer to friend the people i want to - not to have invites from people i don't want to know. Friend me here and we can discuss things face-to-face, on Skype, or whatever ...

I uderstand your doubt in people, Alaskan - I have the same. It is a world of lies and the internet only makes it worse coz it brings out the worst in us.
'How to serve man' - you got that one from the Twilight Zone :)

ps. I didn't take it as an insult and I already accepted your aplogy :)

I believe that change in us as a species must begins with us as individuals. I have tried to be a good, kind person for all my life but 99.9999999% have only abused me for it. I'm not broken yet, because I do trust completely on meeting someone new - I just forgive less (1 or 2 chances is all anyone gets with me, now). But now, due to my experiecne with other humans, I find myself becoming more and more separated and now I'm a virtual schizoid. There's just too much drama and ego out there. We have 'improved', but not enough, yet.

I am also interested in the double slit but I'm curious if it's implications step beyond the quantum world into here. Too many have jumped on it in order to express their entitlement - 'I can be or do anything if I will it strong enough'. This seems like wishful thinking to me without even considering, 'if I'm willing one thing and everyone else is willing another ... who wins?

I know what you are saying, I'm in the same predicament myself, have been my whole life with people, I've become a loner, except for this forum, I don't socialise at all, haven't for years, except with my wife who is also pretty much a loaner too, but in her case because she is from Ukraine and just doesn't know very many people in Alaska yet. I am currently in Iraq supporting the military as a civilian doing SATCOM. I get along fine with the customer, no one would guess I'm a loaner (or maybe I just don't know) because I don't act introverted, but I am far more so than not for the same reasons you wrote about.

These folk who think quantum jumping will get them what they want are getting some exercise, but I don't think willing things to happen will make it happen. Intention plays a part on some level, I am sure, but acting plays the biggest part, if you want something, or want something to happen, go out and get it, or make it happen. My interest in quantum is the science side instead of that kind of stuff, the same as you, from what you wrote. Still, I think the double slit experiment, especially the delayed choice double slit experiment says a whole lot about what is really going on here and what base reality really is.

I too am like you, A - I'm a loner yet I'm not introverted. I'm the weird contradiction/combination of empath and schizoid. When I meet people, I'm 'full of beans;' but I'm most happy, walking on my own - gives me time and space to think. As long as depression or avolition doens't set in, you should be fine 'in your own space'. I have more interesting things to ask myself than others seem to have.

Since my psychic experiences, I believe there could be a possiblity to 'influence reality' but it would be a a very small level until it was developed by us. After hundreds of years we may all be able to move a human hair on a table a matter of millimetres, but thinking that you're gonna win the Super Bowl for the Jets, win the lottery and also be the first human on Mars is reaching, a bit lol.

The 'power' from the double slit might come along the 'butterfly effect' - for example, I want windy weather so I focus on the leaf of a tree to move, which influences the branch, which influences the tree, which influences wind currents. I's possible but i don't know anyone who's capable of doing it :)

I might be considered empathic, well, I have thought I am for a long time, I can too easily feel what someone is feeling, no matter how much someone might try to hide it and it affects me deeply, either positively or negatively, but not sure about the schizoid, I need to look that one up, maybe I am, as much as I edit my posts which is nearly always. I understand what you are saying with the butterfly effect, of course big changes can be linked to small tiny almost imperceptible influences, i.e. not proven, but idea of flapping butterfly wings, ultimately, when combined with other things, producing the start of a hurricane.

The double slit experiment, especially the delayed choice one, demonstrates that the outcome of the experiment is directly linked to consciousness, whether we know which slit the electron etc. went through, if we don't know, a wave interference pattern is produced on the back screen, if we do know, then just two bars are produced by particles. This shows that knowing which slit the electron goes through causes it to stay a particle all the way to the screen detector on the back end, but if you don't know, it never becomes a particle and stays a wave of possibilities, producing a wave interference pattern on the screen.

When a delay was introduced into the experiment, this proved what happens to the electron can be influenced retroactively, if we destroy (erase) the information of which slit the particle went through without viewing it, then it changes to a wave in the past, instead of a particle. This phenomenon has been shown to occur with photons, electrons, atoms and even some molecules, including buckyballs.

There are alternative views on what is happening but believe it or not, the above description of the way the experiment works, as best I could do, is the most accepted interpretation today. For myself, this gives the implication consciousness is the base reality, not matter, and that our reality is akin to something which is computed with error correction built into it.

If the phenomena occurs with matter, such as buckyballs, what does this tell us? Even matter is nothing but waves, until observed, at least, at these minute levels, but no one has been able to prove all matter isn't the same at the macro level too as waves of possibilities which come into solidity when observed. My next question is whether the "all seeing eye" of God (call it what you will) is what causes the universe to exist? If so, then why doesn't this all seeing eye also see what is going on with our double slit experiments and cause the outcome to always be a pair of bars? Maybe God doesn't look that far down, or maybe God is down there but only cares to see what we see at the macro level?

After asking those questions, I'm sure to be viewed as schizoid. Normal people don't think about that kind of thing :p - Here's something interesting to add, do you know what is exactly in the middle between the smallest known micro and macro scales in size? Roughly, our bodies. We stand in the middle able to look both ways.

But what's more productive, building or buying high power lasers just so one can burn stuff or building or buying a laser for optical communication and other technical applications? When the average forum demographic appears to be young male adults what is more likely, the former or the latter?

The answer to the first part is simple: If you do not feel it's personally productive for you, then you have the free will to choose to not participate in discussions that relate to the more technical aspects and applications for lasers.

The answer to the rest is academic as well: LPF will of course continue to attract and cater to the lowest common denominators no matter what subjects are discussed whether they be FSO, LiDAR, LiFi etc; Since LPF, also provides the options to engage in wide ranging topics for discussion especially as pertains to all things lasers, it seems rather self limiting to introduce, suggest or impose what is essentially a non-argument?

I would (and am) arguing the 'why not'?
Why not also offer to the young male adult demographic, some of the more technical aspects of laser applications? Something that may actually be of a more practical and productive use for them in the real world? Since there is a seismic shift underway to upgrade and transition the entire planetary communications networks away from the hardwire and RF technology that is no longer able to accommodate and handle the increasing demands for our digital intensive throughput requirements. By introducing and offering discussions that provide other avenues for skillsets that will obviously be in higher demand because of this shift, LPF is uniquely positioned to easily accomplish this and all the while to also not detract anything from the core focus of laser pointer discussions.

Personally, I find FSO applications more fascinating even at their most basic levels. And the ever growing interest as displayed on youtube channels, confirms that I'm not alone in this view or observation. And really, since when has placing limits on horizons been proven to be anything other than extremely counterproductive?

I edit my posts, too – so much is misunderstood in text.
I’m no scientist, but I do wonder about the double slit experiment and maybe I am wrong in this or have misunderstood the implications of the results. Does the experiement show that our concsiousness can affect reality at certain levels, or does it show that some other force, like God for example, is affecting reality and preventing us from seeing what we want/expect to see, in our close examinations. Is this force showing us that no matter how far our knowledge goes, the laws of physics can easily be contradicted by the force itself – ‘knowing which slit a particle goes through causes it to stay a particle all the way to the detector, but if you don't know, it never becomes a particle and stays a wave of possibilities’.
I fear that humans are always trying to big themselves up. Think of how we believed we were the centre of the universe for centuries. Think of how we view animals as inferior beings without souls or language – how the hell do we know this, for sure? We peal back all the layers of the onion just to reveal even more layers and this could go on forever, like a Russian doll.
I must stress that I am an Agnostic but the desperate attempts by some schientists to wipe out God, at all costs, seems to me the wrong approach. Think of the Simulation Hypothesis – ‘we were created by a superior computer intelligence. At least it’s not God’. Be it a superior computer intelligence or God, it amounts to the same thing, albeit with a different name. Parallel Universes seem as unlikely to me as a God with a beard and an Afterlife of happiness, yet it is becoming a commonly-held belief. I stress again, I am an Agnostic, or maybe moreso an Ignostic. I await death in nervous excitement because it’s going to be the biggest adventure of my life. Only then will I know the answers to my questions for sure, so the court is out until then. I can tell you that this attitude is healthy for the mind – replacing fear with curiousity when it comes to one’s own death. Fore me, it’s gonna be the biggest rollercoaster ride ever or else it’s going to be absolutely nothing (so I won't even be able to be disappointed in the truth).

I have posted this before about this double slit experiment. I think people are trying to explain an effect by giving the experiment the ability to be changed bu people's consciousness. I believe it is just a misrepresentation of the results. It makes for great YouTube videos. It is sort of like the old statistical adage, "correlation does not prove causality".

I'm more of an Occam's Duck kinda guy.

No misrepresentations here.


And a primer for all those that are new to this.
