1) Message boards : News : Arecibo still threatened with closure. (Message 1795308)
Posted 11 Jun 2016 by Profile edjcox
I think it time SETI begins to use steerable arrays that can dwell and stare, Arecibo literally receives stripes in the sky of RF and as the world turns no given object is in view for any length of time.

In light of all the astronomical work being done on finding and categorizing Exoplanets SETI ought to engage in a campaign where these are our emphasis. Improving the odds of detection could be helped a lot by looking where the likelihood of inhabited planets might be. Greenbank as well as the new Chinese telescope are good resources for that focus.

They are likely closing Arecibo due to that and its older technology...
2) Message boards : Science (non-SETI) : Do black holes contain singularities? (Message 1784013)

Sure, what is Hawking Radiation ?

How do you measure it, define it, sense it?

I believe that Stephen Hawking needs to go to an event horizon and show us his so called radiation.. There isn't such a thing....

I believe that the only thing that escapes the event horizon is neutrinos and gamma radiation that are energetic enough to escape at a 90degree angle, these are formed in the soup at and above the horizon. Once beyond the event everything escapes no more and is then in a soup of no time, no mass, no dimension and frankly out of our existence as spatial, time locked, relativistic beings. Gone zilch nada back to the Alpha of pre existence

Stephen needs to prove his Radiation exists and quantify it... He's simply unable to do so except as a postulate..

Yes.

A black hole is a singularity.

It is the common destination of all matter passing through the event horizon of a Black Hole beyond which matters coherency ceases to exist, all quantum particles, subparticles, etc go back into a state of non relativistic time and combine back into the state of the universe prior to transparency when the big bang creating our known relativistic universe of dimension, space and time. A singularity is where space, time, and dimension cease. Infinite density and zero time and zero dimension....

The contention is that amalgamations of sufficient mass is needed in order to create a singularity and ultimately this is the fate of all matter in our universe. So all those Galactic clusters and whirlpools and the interim states of matter such as stars are all just on their way down the rabbit holes of black holes to zero time, zero dimension, with very little able to spew out from the gravitational loci but and occasional cosmic ray and neutrino that gathered sufficient energy before the event horizon....

Welcome Darren

Take some time and read the posts especially from Project staff like Eric.. Your Boinc Manager will handle things pretty well until you get a grip on things and fine tune

Hang in there chances now with the new data sets and sources are better than ever..

We have instances of Gravitational lensing that show distant galaxies and areas of space in multiple images. What's is even more interesting is that when examined in detail the images of the same far off distant galaxies exhibit time dilation, that is to say the same galaxy appears in the lensed images at different points in time dependent upon the lensing and the distance the light has traveled. In other words (Lightyear of origin will vary) so we have in essence a means of viewing an object in different times.. Not quite time travel but certainly temporal variance...

So if one could exceed the speed of light one would still have to cope with the gravity wells of massive objects as one sped on ones way. Like a rippled billiard table fabric the traveler would encounter swerves dips and bends along the path and guiding ones travels would become most difficult there for choosing a destination also trouble wrought.

As you exceeded light speed and by happenstance directed ones travel towards the event horizon of a black hole, the time dilation there would be most interesting. Much akin to a massive rubber sheet under tension of dark matters stretch, black holes would be places in the tensored sheet that suddenly released its hold on matter and the dark matter field would begin to collapse normal space time into the event horizon... But along comes our FTL vessel and flys through that, time dilation is the only factor that balances out the equation...Losing dark matters grip on Space time, the collapse into singularity still ewrfu]3q swic-d3- sd';a

You have to assume an ET species exists at a concurrent level of technology to ours. There is a possibility that ET's may exist at a level of development 100 years in our past or earlier or 150 years in our future or further ahead in time than that. Either postulated ET species would likely not be detected by us as in the first species Radio TX/RX does not yet exist and in the second the ET Species may gave moved beyond RF wave propagation to something as yet unknown to us or only understood at most basic level. Thus the second species we would be blind to as well. Thus time coincidence in technological development is a crucial element for the search.

For some reason we Earthbound species think that all species are maturing in time coincidence to us... Perhaps its a subtle religious thing.. Yet an ET Civilization able to travel through the vast distances between stars likely is technologically superior to us to include communication methodology and techniques. Likely we would not recognize a "signal" if it employed methods like Quantum entanglement, or Neutrino emissions etc... In order for us to have an appropriate intercept receiver we would need to understand the technology and therin lies the difficulty. We just don't know enough.. Even subtle modulation techniques employed today are quite invisible to 98% of the receivers out there. SETI needs to be highly skilled in receiver and modulation technology.

And then there is the dwell issue. The longer your antenna is able to stare at or dwell on a given source point the more likely it is that you may intercept. SETI has utilized principally AERICIBO RT data. By design this aperature sweeps the sky in swaths and has only limited time to dwell or stare a point source before the earths rotation moves the scan past and away. Thus we are examining only short exposures to signal sources, in a limited band, for a miniscule period and likely not repeated for months or year on end.. All of the above factors delimits the current SETI efforts of the at home examination to less than optimal chance for success.

Recent efforts use pointing RT's at confirmed lucrative target sets all will change that success probability... We are entering into an exciting time..

Posted 23 Jul 2015 by Profile edjcox
This will give the project serious dwell time on a given target set of the sky allowing for software that will use advanced signal processing techniques including accumulation and other techniques that can eliminate a lot of noise and short length random signal events. Dwell makes elimination so much easier. Waterfall processing, bragg cell utilization, etc...

Rather than a constantly sweeping swath of the sky the RT's can sit on a emissions area and properly signal process. and revisits as the project will have the opportunity to drive the RT and sit on target sets repeatedly.

The approach will work in conjunction with other data sets, optical and radio data sets that have more likely ET hotspots than others.. Scanning known stars with planet sets already discovered...

It's a fine time to expand SETI horizons beyond our current stripes approach piggybacking on others usage of the RT. This is going to be good....

I think we can take it beyond Ludicrous speed all the way to Plaid....

All you have to do is wait for the specific impulse to build up to something useful although that might take a long long long time. People don't have the time to wait for the speed to build up....

Wonder exactly how long even a short flight to Mars might take waiting for this EM Thruster to build up momentum..

Deceptive fiction...

Neither Greenbamk or LoFar provide data to SETI at this time. To tout this as a visualization of SETI traffic is farcical. Tell us when it actually is occurring. Also the sneaker net to Aericibo should be shown as well.

Ideally this connectivity would exist. It doesn't for now..

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...

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....

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...
