ET Will Phone Home Using Neutrinos, Not Photons
KentuckyFC writes "Neutrinos are better than photons for communicating across the galaxy. That's the conclusion of a group of US astronomers who say that the galaxy is filled with photons that make communications channels noisy whereas neutrino comms would be relatively noise free. Photons are also easily scattered and the centre of the galaxy blocks them entirely. That means any civilisation advanced enough to have started to colonise the galaxy would have to rely on neutrino communications. And the astronomers reckon that the next generation of neutrino detectors should be sensitive enough to pick up ET's chatter."
One may eventually draw a comparison between the huge underground neutrino detectors and the room sized computer.
Of course, ET'll be using transport-layer encryption we've never seen, so it'll just look like random noise and we'll dismiss aliens again :)
Back in the Roman Empire days, they could communicate with Rome using towers built on each others horizon. They then used light codes (similar to morse) to then relay information back to the Caesar.
They had it down to 18 hrs from Great Britan... I think that's damned impressive.
Such a species cannot survive
Not if they're made of meat.
mcgrew's razor: Never attribute to stupidity that which can be explained by greedy self-interest
It does seem unlikely but an extremely long lived life form would tend to see time differently.
Think of your own life. When you are 10 the idea of working on one project for a year seems like forever. Heck you can not even stand ten minutes of down time. It seems sooo long to you.
By the time your 40 a year seems like a short amount of time and five minutes is a blink of an eye.
If you where a 1000 years old and where going to live for another 50,000 years waiting 200 years for a reply wouldn't seem so bad.
Even waiting a thousand years for data to come back from a probe is very doable.
But no I do not think you can have ultra turtles.
See my blog http://ilovecookes.blogspot.com/ for light hearted technical information.
Quantum Entanglement does not transmit information faster than light.
Apparently, it does. Entangled particles *always* have opposite angular momentum. This has been observed experimentally. It may not be accurate to say that one particle is "transmitting" to another. It may be more accurate to say that each particle is independently reading the same variable in some higher dimension. But something is happening. It's not a trick.
Whether or not we can use this information to transmit information of our choosing is another issue entirely.
doing so breaks the link
It's possible that what you mean to say is that observing the system causes it to collapse, in which case you are right. But I'm not aware of any way to actually break the link between two entangled particles.
