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

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

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

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!
To: bunkerhill7
Those must have been nutrino-filled railroad tracks.

Can they get a message into B-HOs head? No way...it's way to thick!
On a more practical note...if they have to send such large number of neutrinos to make sure at least one is detected it sounds like reliability is an issue. I'm a lot more interested in research on quantum entanglement.

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

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

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.

Ummm... scientists voluntarily use the metric system because it’s better suited to their work.

I would be impressed if a dog could bark through 787 feet of solid stone.

fForgive me if your post was sarcasm. It is a little over 780 feet.

The ‘240 meters of solid stone’ was added for sensationalism. This method of Neutrino firing has been tested by firing from Italy to Switzerland and has been received. Theoretically, they should be able to pass through the Earth and a large portion of them unhindered. The distance is not relevant, and I’m part to blame for not changing the headline. What is relevant in this article is that this is the first time a message has been sent.

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.

True. However since the mass/energy of a neutrino is so small it has never accurately been measured, I would have to think the gravitational effect on it is even smaller. But your point is taken, it is foolish to assume since something is too small for us to measure that it does not exist.
