我设计了一个量子机械来让我们看到地球过去的样子,我该如何让NASA去制造它?I designed a telescope that uses quantum mechanics to let us see Earth as it was in the past. How do I get NASA to build it?

此为提问者画的图

That. Is. Awesome!

You might start, though, by spelling “Quantom” correctly in your diagram.

不过,您可能首先要在图表中正确拼写“ Quantom”。

此为答主修改后的图

Next, write down carefully and coherently how your neutrino storage tanks work. Since neutrinos have no charge or magnetic moment and can pass through entire planets without interacting with ordinary matter, your neutrino confinement breakthrough, once demonstrated, will certainly win you the Nobel Prize, and likely make you hundreds of millions of dollars, perhaps quickly enough to pay for your telescope within your lifetime.

接下来,仔细并有逻辑地写下中微子储罐的工作方式。由于中微子没有电荷或磁矩,并且可以在不与普通物质相互作用的情况下穿过整个行星,因此一旦得到证明,您的中微子禁闭突破肯定会为您赢得诺贝尔奖,并可​​能使您获得数亿美元的资金,甚至快得能在您有生之年就支付完您使用望远镜的费用。

Of course…that neutrino mirror. You’re going to need to explain how that works, how it’s going to reflect light (since neutrinos don’t really interact with light much either) and how you propose to set it up. The diagram mentions quantum entanglement, but there is no known way to entangle particles that are not in contact with one another. In fact, if you can pull that off, that’s a Nobel Prize right there for sure!

当然……中微子镜。您将需要解释它的工作原理,它如何反射光(因为中微子也不会与光发生很多相互作用)以及您打算如何设置它。该图提到了量子纠缠,但是没有已知的方法纠缠彼此不接触的粒子。实际上,如果您能够实现这一目标,那肯定是那个领域的诺贝尔奖!

So…yeah…that’s kind of an issue. It’s not clear how entangling a huge mass of neutrons, then transporting them 5,000 lights years away, then assembling them into a mirror…is really going to help you. I mean, do you think that’s really far enough? We kind of have records that far back. I’d really like to see the flight mechanics of pteranodons myself, but whatever, it’s your project.

所以……是的……这是一个问题。尚不清楚如何纠缠大量中子,然后将其运送5000光年,然后将它们组装到镜子中……可能会帮到你一点。我的意思是,您认为这真的足够吗?我们早就有记录了。我真的很想亲自了解翼龙的飞行原理,但是无论如何,这是您的项目。

On the other hand, maybe you should start small and build your neutrino mirror like, a light week away and see if you can read some of the Tweets Trump has deleted since then. I mean, it would be a bummer to spend that kind of money and wait literally longer than civilization has been here just to find out you screwed up the focus or something like on the Hubble.

另一方面,也许您应该从一个光星期开始,从小处开始,建立中微镜,看看您是否可以阅读特朗普自那时以来删除的一些推文。我的意思是,花上这笔钱,并且等待比文明出现以来更长的时间真是太可惜了,要是到最后仅仅发现你搞错了方向,或者像是Hubble望远镜上一些糟糕的事就不好玩了。

In fact, that’s probably the way to go anyway. 5,000 light years is a long, long, long way. Even if we had a perfectly ordinary glass mirror out there a hundred times the size of a solar system, we still couldn’t see the Earth in it’s reflection. The largest telescopes in the world today can’t see the Apollo landers left on the moon fifty years ago, and the moon is only 1.5 light seconds away.

实际上,这种方法也很有可能就是我们寻找的那种方法。 5,000光年是很长很长的。即使我们有一个非常正的玻璃镜面,它是太阳系大小的一百倍,我们仍然看不到地球的反射。当今世界上最大的望远镜无法看到五十年前遗留在月球上的阿波罗着陆器,而它距月球只有1.5光秒。

These same telescopes can only detect planets orbiting stars a few hundred light years away by inference…by looking for the slight dimming when a planet crosses in front of the star and things like that. So even if you had a giant neutrino mirror out there right now, and a giant optical telescope here looking at it, it would be hard to detect the Earth (even knowing where to look) much less see anything useful on it.

这些大同小异的望远镜只能通过推断来探测绕着几百光年远的恒星运转的行星……通过寻找行星越过恒星前方时的轻微变暗之类的东西。因此,即使您现在有一个巨大的中微子镜,并且有一个巨大的光学望远镜在看着它,也很难检测到地球(即使知道从哪里看)上任何有用的东西。

But don’t give up. Heck, you’ve got about twelve ideas here that could win you the Nobel Prize if you could make any of them work. If you keep looking, you might come up with something slightly more practical, but just as awesome. I mean, we actually can use science to learn a lot about the past. Artifacts go back thousands of years. Tree ring series go back 12,000 years. Ice cores go back millions of years. Fossils and geologic evidence can go back billions.

但是不要放弃。哎呀,这里有大约十二个想法,只要您能实现其中任何一个都可以赢得诺贝尔奖。如果继续研究,您可能会想出一些更实用但又很棒的东西。我的意思是,我们实际上可以利用科学来了解很多过去的知识。人工制品可以追溯到数千年前。树的年轮可以追溯到12,000年。冰核可以追溯到数百万年前。化石和地质证据可以追溯到数十亿年前。

We may not have an easy time viewer, but we can tell a crap ton about the world, its past, and its future, if we know how to look.

我们可能没有容易获得的时间回看器,但是如果我们知道如何回溯时间的话,我们就可以知道大量有关世界的过去和未来。

So keep looking.
