It looks like there is great need for a more effective system of detection.

Can they get a message into B-HO’s head?

[scripter]

This is really interesting. I love technology.

As if a 240 meters of solid stone would muffle the neighbors’ barking dog.

If you tap on a railroad track with a hammer one mile away you can hear it at the other end with your ear on the track [with no train coming]

duhhhhhhh
moronic scientists never had a childhood evidently

U.S. taxpayers paid for this research, it should be expressed in yards, feet and inches. Get the UN and its standards out of the United States.

If you use neutrinos, at least the European kind, you send them tomorrow’s lottery numbers today!

[Savage Beast]

Only a few years ago, the first computers were as big as rooms, and the internet had not even been conceived.

[Bobalu]

Makes me think of the very early days of wireless experimentation.

One of the earliest transmitters (AC spark gap)

The matching receiver (iron filing detector)

This is the actual distance covered during the public exhibition

Did Uhura acknowledge the call?

You have to wonder why, after decades of listening, we have not detected radio signals from extraterrestrial civilizations. I've always had a suspicion that it is because there are much better ways that we have not yet discovered to communicate across great distances than by using radio signals. We have broadcast radio signals on a large scale for less than a century, and perhaps we, like other civilizations, will soon discover a better way.

I’m an American. How far is 240 meters? Is that the same as 240 metres? If you talk to me in terms of feet and inches, I’ll understand.

Because of their neutral electric charge and almost non-existent mass, neutrinos aren't affected by magnetism or gravity, so can travel almost unimpeded.

Anything with energy is affected by gravity, which would include neutrinos.

North Carolina Researchers communicate without wires through 240 meters of solid rock.

That's nothing. Just last night, I said something to my 17-year old son, and he acted like he actually heard it!

[Gaffer]

Sounds to me like an antenna transmission system with a beamwidth too small to be practically useful. Aperture size, gain and directivity rules wouldn’t apply here...

It would seem to me a damned difficult thing to point or receive....

[bunkerhill7]

This is already obsolete- It can be blocked by beams of anti-neutinos.
