Snowden talking with Tyson

”

He added that encryption would render communication indistinguishable from “cosmic microwave background radiation.”

“If you look at encrypted communication, if they are properly encrypted, there is no real way to tell that they are encrypted,” Snowden said. “You can’t distinguish a properly encrypted communication from random behavior.”

Undetectable Extraterrestrial Signals --"Advanced Civilizations Could Be Using Ghostly Neutrinos or Gravitational Waves"


Several of the world's leading astronomers -- including Great Britain's former astronomer royal, Sir Martin Rees -- believe advanced extraterrestrial civilizations, rather than using different radio waves or visible light to signal, may be using an entirely different communication medium such as ghostly neutrinos or with gravitational waves (ripples in the fabric of space-time) or using communication mechanisms we cannot begin to fathom.




Lord Rees, a leading cosmologist and astrophysicist who is the president of Britain’s Royal Society and astronomer to the Queen of England believes the existence of extraterrestrial life may be beyond human understanding.



In fact, Davies writes in his book, The Eerie Silence, that advanced technology might not even be made of matter. That it might have no fixed size or shape; have no well-defined boundaries. Is dynamical on all scales of space and time. Or, conversely, does not appear to do anything at all that we can discern. Does not consist of discrete, separate things; but rather it is a system,or a subtle higher-level correlation of things.

Are matter and information, Davies asks, all there is? Five hundred years ago, Davies writes, " the very concept of a device manipulating information, or software, would have been incomprehensible. Might there be a still higher level, as yet outside all human experience, that organizes electrons? If so, this "third level" would never be manifest through observations made at the informational level, still less at the matter level.

100 years is a blink in the eye and in fact now since we have gone digital our noise is much less.


Scientists may have an extra challenge when it comes to detecting alien civilizations: a time limit.

A new study suggests that intelligent aliens, if their technological progression is similar to that of humanity's, are likely to have moved away from noisy radio transmissions to harder-to-hear digital signals within a 100-year time frame. That offers Earth just a narrow window in which to pick up any signals from extraterrestrial civilizations.?

"Based on the results that we looked at, if we assume that the civilizations are humanlike with similar technological progress to us, we calculate the probability of making contact is roughly one in 10 million," the study's lead author, Duncan Forgan, told SPACE.com.????

The time it takes a planet to go "radio quiet" dramatically restricts the types of signal it sends into space and our chances for eavesdropping on them, said Forgan, a postgraduate researcher at the University of Edinborough in Scotland. [Poll - Is Earth Ready to Meet an Alien Civilization?]

Forgan and his team applied their technology-development time scale to a simulation of the galaxy, based on the assumption that the pace of an alien civilization's technological progress would be similar to that on Earth. Based on this simulation, the researchers determined the 1-in-10 million odds of humans accidentally stumbling across a transmission from aliens.

The researchers, whose study will appear in an upcoming edition of the International Journal of Astrobiology, focused their work on the expected eavesdropping capabilities of the Square-Kilometer Telescope, a radio telescope slated to be completed by 2023.

civilization that is trying to communicate with us using encrypted signals. Do they only want the NSA to know?

Sorry, planet is mine now. I am off to explore, good luck with the election and global warming.

I was thinking: Good thing they've finding habitable planets now, cuz if Trump or Clinton are s/elected, we're gonna need an extra one.

It may be a bit of a long travel, but if I recall correctly time slows down the closer to the speed of light you get? So we would not age as much I think?

...right in the middle of 2MASS J23062928-0502285 (aka TRAPPIST-1)'s booming New Deal! I'm ready! When do we go?

I am sure they still have tons of funding and are competitive on a world market. There is no way that we could have USPSed the space program right? I am off to ask them to borrow one of their ships...I am sure they have a couple extra ones not in use.

So we are looking at a 400 year trip providing all goes well.

The two closest planets are apparently tidally locked due to their close orbit, so that would make one side hot, and the other ice cold.

If water is constantly evaporating off the sunward side, and being precipitated out on the cold side, wouldn't the water eventually end up almost entirely in ice caps far from where it's warm enough to support life?

An atmosphere like that of Venus would keep the entire planet hot I suspect, yeah the side toward the star would be somewhat hotter but a really dense atmosphere would distribute it fairly well.
