So, yesterday on Twitter I got to thinking about laser-launched lightsail nanoprobes:
Currently, the big idea is to launch teeny-tiny lightsail probes at neighboring stars to get a look around — current thought is that technology as it is now could handle boosting some 1 gram probes attached to 20 meter lightsails up to 20% of lightspeed.
(I’ve cued the video to a bit about how teeny the working part of the probe would be — if you’re so inclined the whole video is a long, academic discussion of the whole idea that’s pretty decent if that’s your cup of tea.)
With only a few — but even better with a huge cloud, as I briefly fantasize about elsewhere — we could get a fine look at a stellar neighbor and see if there are any planets there that would be practical targets for a generation ship to settle. Think big, I say. Best to get humanity out of this fragile little egg basket we call Earth. Not just into the rest of the Solar System, but into others if we can manage it.
But nanoprobes, good for peeking at the neighbors, could be great for raw astronomy and investigation of the nature of the universe.
The Quanta link in my lead tweet above is about theories regarding the behavior of dark matter. Imagine how useful for that and other questions we itty-bitty humans have about our gigantic universe it would be to launch a gigantic lens of nanoprobes sailing off in a couple of different directions. To fire them out of the plane of the ecliptic and out of the cloud of particles and matter the Sun drags with it through space. To shoot them toward things we want to observe at 20% of lightspeed and compare the observations with what we see when that light and radiation reaches Earth. To fire them off the other way and let them crawl back in time (effectively) to compare to past observations.
To build expanding lenses light-minutes across in interstellar space, peering deeper and more clearly into the universe than humans have ever managed before.
Take some time to really think about it. It’s a breathtaking opportunity for pure science. And pure science, practical-minded friends, pays off in the long run.

Sorry to inflict this on you, but it was WAY too bizarre not to share.
Give it a listen, it’s one of my freebie stories, a real shortie — only six minutes long, under a thousand words about one possible implication of laboratory-grown meat products.
There are two other stories on my YouTube channel so far, both software-read. Now that I have broken down and gotten a bare-bones basic microphone, I’ll be posting more like this, read by me in my very own voice.
You’ll notice, I think, that my voice is just okay for this kind of thing — part by nature, part by lack of experience. Reading aloud isn’t something I’ve really done before, aside from a few kids’ books for my toddlers. I’m no Morgan Freeman.
In any event, I hope you’ll enjoy what you hear.
This experiment was prompted by a blind relative who wanted to hear my stories. I decided to give a free text-to-voice program a crack at ‘reading’ a few of them out loud and put them up on YouTube for anyone to hear. Various family members visit her often with various internet-enabled devices in tow, so this seemed like an interesting way to go about it.
Sure, I could read them. And I might go that route one day. But money is tight and I can’t really justify (or find!) the money to provide a good microphone, a good webcam, and a quiet recording space free of the banshee wails of my two toddlers at the moment.
So for now, give the robot voice a listen.
If you’d like to hear more, subscribe to my YouTube channel. I plan on putting new ones up regularly.
