content: We are lind of hitting the limits with it, 5g and mm waves are attenuated by air , foliage and buildings, there must be some better way.I think its the neutrino can be sent in three flavors at different speeds, can be sent directly through the earth at nearly the speed of light, much faster then fibers or RF from satellites. Maybe we arent seeing aliens because they used RF in the beginning then after 300 years they switched. Entangled pairs dont seem to work because you cant send faster then light info through them.So whats next? 6g? I hear that gives you not only cancer and corona but also genital warts. gross.

I could make a phone call in the woods or at my neighbors house. I killed it by holding it up to one of those neon ball lamps though. 5.8ghz sucks

content: Quote from: coppercone2 on March 07, 2021, 06:44:00 amI often thought about "what if" scenarios with neutrinos. Tapping into that would be mind blowing in terms of communicatingthroughthe globe. Also, even more interesting, neutrinos would allow us to peer deep into planets, or even stars, and build 3D maps of their structure. Neutrinos would be a very valuable science tool.

content: well I think you would need to make isotopes that have a short half life and let them decay in a form of morse code. it has been donehttps://physicsworld.com/a/neutrino-based-communication-is-a-first/I expect this to be of similar to use as ELF communications to submarines, low bit rate and very expensive for a very long time, I would not see many civilian applications outside of like planetary communications given that you need to make radio active materials. the only modulation you can do is 'are there radio active materials are there no radio active materials'.I suppose you can move a neutrino generator around on a rail system or something, since it may be possible to triangulate its position and use that as information. maybe a nuclear reactor on a rail car on mars or something if a good detector is made.https://targets.fnal.gov/NuMI_neutrino_beam.htmlhttps://www.symmetrymagazine.org/article/november-2012/how-to-make-a-neutrino-beamI did not know you can focus them, I was only aware of antineutrinos that have a random radiation pattern. So it looks easier, so the momentum vector is transferred, it does not shoot off randomly like I thought it did.

content: So much RF that all kinds of digital devices run totally off of RF and never need batteries. Even transmitters and transceivers. You wont be able to 'unplug " them or turn them off.You will be plugged into the grid 24/7 and your location and heart rate will be known down to around 2 cm.

Maybe it was less granular but you also had an official recognized your face, smell and made a mental profile of you whenever you traveled between regions. For a Nazi regime, a sign in sheet at a place of worship was enough to detain you, or someone to say 'yea it kinda looked like that guy'..this comes to mind

content: Quote from: cdev on March 10, 2021, 04:31:25 pmYeah, but quantum entanglement actually doesnt work that way. For communication it is not better than shipping hard drives by DHL.Neutrinos are extremely unlikely to interact with matter (cause there is just so much space between atoms) so unlikely and inefficient.Narrow beam or so called point to point RF with beamforming is probably the next step. Satellites already do this. They can track a F18 from a satellite with a laser, having high speed connection to the aircraft.
