This is a frumpzatious (a valid word that I created yesterday, in theory) picture.

The breaking of the sound barrier is not just an audible phenomenon. As a new picture from the U.S. military shows, Mach 1 can be quite visual.


This widely circulated new photo shows a Air Force F-22 Raptor aircraft participating in an exercise in the Gulf of Alaska June 22, 2009 as it executes a supersonic flyby over the flight deck of the aircraft carrier USS John C. Stennis.


The visual phenomenon, which sometimes but not always accompanies the breaking of the sound barrier, has also been seen with nuclear blasts and just after space shuttles launches, too. A vapor cone was photographed as the Apollo 11 moon-landing mission rocketed skyward in 1969.


The phenomenon is not well studied. Scientists refer to it as a vapor cone, shock collar, or shock egg, and it's thought to be created by what's called a Prandtl-Glauert singularity.


Here's what scientists think happens:


A layer of water droplets gets trapped between two high-pressure surfaces of air. In humid conditions, condensation can gather in the trough between two crests of the sound waves produced by the jet. This effect does not necessarily coincide with the breaking of the sound barrier, although it can. To learn more, click here.


The aircraft carrier was participating in Northern Edge 2009, an exercise focused on detecting and tracking things at sea, in the air and on land.

I find the conical shape or vortex interesting. I would like to hear what theoretical physicists have to say about it. I also wonder, and think that just about any type or shape of aircraft would make the same general shape. Maybe some would have bit longer, wider, or more narrow. Would a spherical or saucer shaped craft produce the same general shape? I would like to see this done again with the plane in the middle of the clock so to speak, with cameras at 12,3,6, and 9 .. but I imagine that would be fairly hard to do.

I saw a little bit on the news about NASA planes to revamp shuttle program, and I wonder, are we still stuck with using rockets? Whatever happened to the idea of rail launched vehicles?

Okay, so I will link some other things I think are really interesting, it's NASA video and communications, not crank stuff. I mean are people so afraid to talk about things that aren't explained?

Hey Meem,
The only progress I've heard with rail launch is weapons. I'm not sure if the thrust to weight would be enough for any large payload.
As far as new tech, I have heard alot about carbon nano-fibers being used for a tether. It sounds pretty far out, but there is serious research going into space elevators. That would be an exponential reduction in energy waste to put anything into orbit.
Thanks for the black helicopter links! I don't put much scratch into most UFO sightings, excepting for what I would think are probably govt programs that I would just assume stay 'black'.
Peace,
Ron

But, it's so much fun to talk about the men in black. I just have to say this first, I'm not a conspiracy theorist or some Area-51 believer, nor am I waiting for hale-bop or whatever that comet was to come an take me home. I think it is for the most part, out-right ignorant of "us" to assume that "we" are the pinnacle of intelligence "out there." From my understanding of evolution, life started in the ocean billions of years ago and crawled out onto the land. I have often wondered would it not have been possible for more advanced intelligence to have started in the ocean? I mean take myth of Atlantis, could it have been a platform of interaction that a "race" used to study us? Maybe some aliens could be "alien?" does it eliminate the possibility that they have always been here, and they live in the ocean?

I saw another video on you tube about the first tether experiment, spoofed by some UFO enthusiast. As far as UFOs, aliens, and government experiments go ... I'm interested, have thoughts, and will keep an eye open, but I am far from holding any convictions one way or another. I just like to engage possibilities.

I know, I know it's crazy stuf ... but why are people so afraid to engage in talking about it? Because there are people who dress up like someone from star-trek?

just be open!

The tether lol
http://www.youtube.com/watch?v=As-wYmFYb3I&feature=related

About the tether though ... and something mentioned about this incident, it had a large power surge that caused the incident ... I think mentioned something like a
2-10 fold increase of what was expected? What if they used nano-silicon structure for the conduit? You know, like the stuff this guy is working on,

Stanford researchers have found a way to use silicon nanowires to reinvent the rechargeable lithium-ion batteries that power laptops, iPods, video cameras, cell phones, and countless other devices.

The new technology, developed through research led by Yi Cui, assistant professor of materials science and engineering, produces 10 times the amount of electricity of existing lithium-ion, known as Li-ion, batteries. A laptop that now runs on battery for two hours could operate for 20 hours, a boon to ocean-hopping business travelers.

"It's not a small improvement," Cui said. "It's a revolutionary development


Tether problem solved?
Meem
I would just like to clarify, that I don't browse the internet for uh UFO stuff ... I mean I do but you know, it's not like anything serious? lol This is my most favored youtube of all time at the moment. Guy's amazing. How many times do you think he's fallen down, gotten back up, and tried and tried again? To advise, it's doesn't start getting amazing till about 50ish %

Hi again, Meem,
I’m with you on a lot of how you look at these things. I really enjoy watching and reading about what may have gone on in ‘prehistoric’ times. I try to think of ancient civilizations as very similar to today’s, in terms of how people think and act.
In the past 12 thousand years or so, the human mind and its capabilities must have been basically identical to ours, in terms of hardware at least. So, when trying to understand what we know from record, why would so much of the ‘odd stuff’ always be considered myth? I have always had a hard time thinking about , as one example, the Greeks and their Gods. We have a great deal of very specific records from the Greeks and we can very distinctly separate their science (fact) from fiction (plays).These concepts, along with philosophy, social structure and civics are all well defined and understood. We can still be entertained by their arts and learn from their scientific methodology, so why are we so quick to dismiss their mythology as complete fiction, when they very clearly talk about the Gods as living among them? I know that sounds completely absurd, but I just don’t think that they were so naïve that everything that they didn’t understand would be so pervasively thought of as ‘magic’ when they clearly had some type of grasp of how the physical world worked. I’m not sure where that leaves my understanding of their Gods living among them, but I certainly don’t like to assume it was all nonsense.
There were many other advanced civilizations that we know about over what we consider the modern age (agriculture and domesticated animals about 12K years ago, or so?) that we have at least some record of and some of the far out stories, I believe, are worth serious consideration.
Thanks for all the links. I’ll try to take some time watching them over the next couple of days. Maybe we can narrow done our ‘black’ list to some interesting discussions!
Peace,
Ron

You know, I've been attracted to Greek mythology and philosophy. When I actually started learning more about it all, it became even more fascinating. I think it's foolish how easily some people are ready to throw it out the door, it's ancient this is the future. The most amazing thing about it to me is the fact of how old it is and it's level of sheer brilliance. The most striking to me, Plato's works and "records" of Socrates. For a bunch of "ancient fools," there sure had some sort of grip on reality and perception that seems to have eluded most modern people. What ever truth is, it has to be something that these men long ago had an inclination of.

There's all sorts of "indications" or possible connections to "space-men" in ancient cultures. Some of the South American temples with the "craft" depictions and "men" in them. There's a lot of that particular type of thing everywhere, long ago. People have always interested me the most. What grips me more so about Greeks and philosophy, was what happens when you graph some of the concepts laid out in Plato's republic. My prof. did them section at a time, when I studied for tests, I had all of them together and well .. it was just interesting. You know, the book says it's about justice, but I got the impression that it was really about seeking truth. I remember my Prof. saying, "before you read this you need to be prepared. Plato hides what he's actually saying, you have to look for it." Sometimes I wish I could ask those men questions, but they did a most excellent job of answering most of them. I wrote a parable after reading it, turned out pretty well ... I think, at least. Was pretty fascinated how Plato presented Socrates as having this concept of the good, and Plato seemed to have it as well ... along with a singular God concept. That had to be fairly dangerous back then. I imagine that's part of what Got Socrates killed, well at least how Plato seems to describe it. I guess Plato didn't have to worry too much since he had a strong family with money and position.

Didn't they invent geometry? People say geometry is useless ... but ... it has to be the first step in learning topology which I think is far from useless. I think they had tremendous vision and awareness for a bunch of "cavemen." Well at least they seemed to. They are the backbone of western civilization today as we know it, but seem to be forgotten by most people. There's a lot that can be learned by learning about them.

woah, saw this in the local paper too. Looks amazing.
Meem
Totally. Makes me wish I were a pilot or astronaut. cool.gif
Ron
Sorry for getting off topic. Maybe we'll start another thread for 'Ancient Black Helicopters', eh Meem?
Peace,
Ron

Meem
I think if they are ancient, we should call them black "horses," perhaps even "sheep." The whole point of the color is to indicate the dark undertone of secret society. The naming of the device, such as the helicopter, is to show it as man's invention. Men didn't have helicopters back then! Only the aliens did, tee hee. I guess for the ancient ones, maybe we shouldn't say horse or sheep because, men didn't invent those things, but they did try to control them, and both where a part ... used as a means of control ... for those with power over those without. In ancient times, men played on a grand stage for power, that's is still happening this very day. We have not proved ourselves any better, if but only on a case by case basis.


(edit)
To get us back on track,
http://en.wikipedia.org/wiki/Prandtl-Glauert
this definition might help. It seems there are all sorts of evidence that points to singularity. If this is the case, is the uncertainty principle actually the not certain principle? What is the quantum singularity?

Do you have a small rodent tied to your computer?


The PG singularity has nothing to do with quantum singularities aka black holes.

Meem
Eh? Aren't they both thought to be types of physical singularity? What is physics?
rpenner
The singularity is one in this expression, which is an approximation to fluid flow.

http://en.wikipedia.org/wiki/Prandtl–Glauert_transformation

But this approximation is not very good for Mach speeds between 0.7 and 1.3, and therefore is unreliable at Mach 1.0. So this particular mathematical singularity is not of supreme physical importance, which is obvious since we even have supersonic passenger airplanes.
