The question I have is does Man go well with a red or a white wine..

To many things need to come together

Able to communicate and decipher

Able to transport across many many light years of distance faster than light speed.

Have some actual interest in making the journey.

Has the wisdom to not impact us by becoming known (ie Prime Directive)

To us the ET will appear magical or mystical as Humans have always viewed those encountered with superior intellect and technology in such a fashion..

We have a narrow vision of ET, assigning them the attributes we are familiar with. Imagine if ET was already here but hiding in plain sight. Likely we would not catch on unless willingly revealed to us...

Imagine of ET had a lifespan 10's of thousands of years beyond ours a real Alpha - Omega span and time enough to assimilate and act upon the universe. ET might just be like bacteria are to us. Everywhere but limited in interaction..

Our view of ET is myopic at best.

Listen up folks...

We have had radio technology slightly over 100 years... That means signals from our planet have been traversing the universe (ever diminishing in power content and therefore rang) reaching out at best a bit better than 100 light years..

Let's say we then have a sphere of radio range around us of that distance. So how many planets supporting life fall within that range??

Question two. What is the level of sophistication on said planets at any given instant during that 100 years?/

Question three. What is the likely hood that a given ET civilization would likely be time coincident with our technology and even listening?

Question four. Let's assume they have managed to obviate Einstein's speed limit. So what technology would they be using to communicate and or be scanning the universe with for intelligent signals? Radio ? Signal Flags, Smoke signals, reflective mirrors, etc etc. Likely employing means and methods we could not decipher and they likely could not decipher ours either..

As they say in NJ dontworryaboutit It's so far fetched and so unlikely that we will probable be asteroid impact dust well before then...

Let's see

"paranoia strikes deep, into your mind it will creep, it starts when your always afraid, step out of line, the man comes and takes you away"....

Those who would trade their Liberty for security shall not get security and will not have any Liberty....

The only thing you have to Fear is Fear itself....

terror is a state of mind, succumb to it and trade your Liberty for it's suppression then you have given them the victory and upper hand they seek....

Posted 6 Oct 2014 by Profile edjcox
Unless electrons have mass or they somehow disturb matter by inducing a momentum I think this experiment needs to be performed in a zero gravity enviorment like aboard the ISS.

The amount of thrust produced is so damn small that it would take a long long time to build up any momentum and silly things like gravitational influences might overcome such a miniscule thruster...

I agree they were air dropped flares... We used them out on the ranges at Fort Bragg all the time. They can be dropped from fighters, c-130, c141, Galaxy, etc... The will hang in the sky for a good while and wink out when exhausted of white phospher. A spectral analysis will reveal the chemicals burning..
11) Message boards : News : UC scientists find first interstellar dust particles (Message 1569903)
Posted 10 Sep 2014 by Profile edjcox
What if any is the difference between solar system dust particles and those labled "interstellar"... I suspect the origins of dust in general in space is somewhat difficult to determine. While dust near a planetary body might be associated with said planet in actuality the gravitational wells of planets act as a vacuum as the solar system travels through interstellar space so dust is likely to be of indeterminate origin.

Given the numerous collisions in planetary space, asteroids, comets, meteors, etc. Dust is far more prevalent near a star. Unless we can have Voyager's and Pioneers in a few decades do collections I maintain that dust within 1/2 light year of the sun is most likely of Sol system origination with random strays form elswhere's exceedingly rare and likely exhibiting no unique properties to allow differentiation.

So what you still have to have something at each end... With distance there is time, with time differential there is loss of coherency, without coherency and Rx and TX at both ends there's no communications...

Would suggest that "With Obama buying contraceptives for the great unwashed US" is a political statement that does not belong in this forum but rather the politics forum.

Posted 1 Jul 2014 by Profile edjcox
The Senate has decided to withdraw US participation in ITER. The fusion reactor being built is apparently becoming more expensive all the while and the US part of the expense ever growing...

I can see it now. We have to beg for energy while the participants essentially harvest free fusion energy...

Personally think its a dumb move...
15) Message boards : SETI@home Science : How will the universe end - with a bang or with a whimper? (Message 1524660)
Posted 5 Jun 2014 by Profile edjcox
Atomic structure at the event horizon ceases.

Due the intense gravitational effect in proximity to the accretion disk matter gets stripped of it's fabric and coherency. Conventional atomic structure, ie neutron, electrons, protons all lose their minds and guidance and are simply free to fall towards the gravitational well that is the black hole. Massless particles not attracted are free to do what they will. We do not exactly know what that is as orbital dynamics end. Cohesion of atoms, matter ceases. Energy is released and may actually leave our universe into the oblivion these cosmic sinkholes represent. We have observed jets escaping from accretion disks, Understanding how and why these mass containing jets can overcome a black holes gravitational well, what forms them and how where the energy comes from remains the province of theoretical astro-physics. We have a very foggy notion but it's a grand mystery.

The mystery is what/where and when does all that stuff go. Is there some escape hatch in there from our universes existence and space time. Do black holes represent some cosmic drain back into the primordial before the big bang. Is this the way back to square and time zero? Lot's to think about, but we have little understanding and no good way to see what goes on at the edge of our universe and in a sea of no time /all time /some time.......

My thought is that when the expansion stops and the condensation begins, the many black holes will be swallowing up and taking mass in universe someplace and like a piece of swiss cheese the universe will fold and simply pop out of existence of the then here and now into.... I'll leave that undone....
16) Message boards : SETI@home Science : white noise (Message 1521495)
Posted 27 May 2014 by Profile edjcox
Yes essentially SETI is attempting to discern pink noise from white noise...

To do that SETI screens signals with catalogue of known pink noise generators to screen away those that might be of terrestrial origin or even signals from the multitude of off world known transmitters (Voyagers, Mars probes, Pioneers, etc etc.)

Sieving and screening down all that "white noise" is also a noise threshold issue where signal sensitivity is an issue. Fundamentally SETI is always at a disadvantage as we are using receivers on the planets surface that can be impacted by all manner of signals, fundamentals and harmonics, up and down, from rather mundane sources like radars, overflying aircraft, satellites, reflections of these, etc.

Perhaps in the future we can build a Lagrange point package and set up a scan location out there in space away from so many interferers..

Posted 23 May 2014 by Profile edjcox
I am hoping that this testimony and the way it was cordially received may be an indication of continued interest and funding for the Radio Telescopes and SETI as well.

There simply was not enough emphasis on the collaborative aspects of SETI at Home and the multitudes of people running the program and providing the data processing. More emphasis on the "human" aspect of this volunteer effort and the willing collaboration of so many from so many of the Nations of the world. This in turn would show the Congress that funding provided would allow SETI to continue to operate engage many people and perhaps even evolve in a greater enterprise in the "search".

Some feedback on whether the testimony bore fruit would be appreciated..
19) Message boards : SETI@home Science : What would we do if we found intelligent life elsewhere? (Message 1516819)
Posted 16 May 2014 by Profile edjcox
Let's clear some things up

1. SETI is scanning the EM Spectrum in a narrow specific area. That EM radiation we are scanning has traveled countless light years to reach our receivers. That means anything ET we discover is in the past depending on the source likely many many years in the past and the originators have moved on in time to our present.

2. We are currently stuck in a reply methodology of EM radiation. So even an ET discovery would not be able to be replied to in less than once again the time in light years a propagated reply signal would have to travel to the point of origin of an ET transmission. So we can relax as the time it takes for a signal to get there is less likely to be time coincident with the technology that originally generated the discovered ET signal.

Our own technological progress in less that 200 years should give you some comfort. We've gone from broad band AM spark transmission, to narrow AM, FM, and now digital transmission of high complexity in modulations, frequency, and signal direction. We already employ laser light in huge applications and we are exploring all manner of other means to include particle emissions etc. We can modulate light throughout the spectrum, generate coherent light, IR, X-Ray, and Radiations such as Gamma, etc. All can be employed to convey communications. As time marches on how will we be communicating in say 200 years?

The issue raised is that in addition to looking for ET in the SETI radio spectrum (and within modulation techniques we understand) there is the issue of time coincidence where our listening with an appropriate receiver and technology takes place at the time the ET "signal" or emanation bathes our receiver and planet.

Our chances are slim, but we have a vast universe to listen to and countless billions upon billions of possible sources.

If we ever do decipher a ET source. Rest assured it likely will have originated far beyond our immediate neighbors, perhaps even in a far away galaxy where our ability to discern a radial aperature would be next to impossible.

So let's not forget to travel from there to here would take technology and energy control we have not yet even conceived of or invented...

Sleep well, keep pluggin away, who knows, we may get lucky...
