科技资讯:世界上首次中微子通信服务_by博业体育app

Neutrino communications中微子通信ET, phone home外星人，约见家中The worlds first neutrino-messaging service世界上首次中微子通信服务PARTICLE physics is all very well for addressing trivial matters like why are we here? (see article). But some people question its practical usefulness. To answer such naysayers a group of physicists at Fermilab have just submitted a paper to Modern Physics Letters A in which they describe how they have built themselves a neutrino-powered telephone.粒子物理学总是能很好地解决我们生活中遇上的像为什么我们在这里？这类的琐事。但是一些人会批评它的实际可行性。

为了避免类似于的批评，费米实验室的一群物理学家刚向物理学界权威杂志Modern Physics Letters A递交了一篇论文，论文中叙述着他们怎样为自己顺利自定义了利用中微子载波的无线电通信电话。Naturally, their neutrinophone is digital. A pulse of neutrinos (small, elusive subatomic particles with no electric charge) corresponds to the digit 1 while no pulse corresponds to 0. The neutrinos themselves are created by smashing bunches of protons into a target made of graphite. They are detected roughly 1km away by researchers who, in their day jobs, work on a neutrino collaboration called MINERvA. By modulating the pulses of protons the group was able to send a message in binary that, when translated, read neutrino. Whether this will go down in history alongside Alexander Graham Bells first message, Mr Watson, come here, I want to see you, remains to be seen.似乎，他们的中微子电话通信是数字化的。

一个中微子（一种不带上电荷形态怪异的亚原子粒子）脉冲对应着逻辑电平1，没脉冲时就对应着逻辑电平0。中微子产生于一些质子束炮击一个石墨目标后产生脉冲介子，介子随后裂变而出。整天工作于一个「主流经器之中微子V-A交互作用实验（MINERvA）的研究员们在大约在一公里远处能检测到中微子。

通过对质子束脉冲的调制编码后，以二进制码的形式展开中微子传输。否这将沿袭亚历山大?格拉汉姆?贝尔(Alexander Graham Bell)的历史，以Watson先生，请求过来，我想要看到你展开首次中微子通信，我们拭目以待。The point, though, apart from sheer wackiness, is that neutrinos are not easily intercepted by collisions with other sorts of matter. If humanity wanted to broadcast its existence to intelligent life forms that might be out in the galaxy listening, a modulated beam of neutrinos would be a good way of doing so. Conversely, some people argue that listening for ET at radio frequencies is the wrong approach. The right one, they think, would be to build a neutrino-receiver. And that would mean plenty of work for neutrino physicists. Perhaps, then, from its makers point of view, the neutrinophone is not such a nutty idea, after all.然而，最重要的不仅是其怪异性而且中微子在传输中当受到其他物质的碰撞时不更容易被毁坏。

如果人类想要让远在银河系的地方听见充满著智慧生命不存在性的广播，那么经过调制的中微子光束则是使他构建的一种很好的方式。忽略，一些人指出利用无线电广播频率收看外星人是一种错误的方式。他们指出准确的方式应当是搭起一个中微子载波的接收器。

这就意味著中微子的物理学家将必须做到大量的工作。那么，或许中微子电话的制造商不会指出，却是中微子电话并非是一个可怕的创新。
