So there are dictionaries that will tell you stolidly that a rabbit hole is a hole in the ground, dug by a rabbit.
But the edgiest ones take the Lewis Carroll view that rabbit holes are much more than that.
I’m always more than a little unsettled by the image of the little girl who follows a white rabbit and ends up losing control completely. And that feeling of strange estrangement, of the total detachment from reality, it dogs the term now. When we go down a rabbit hole, we chase the known into the utterly uncharted, the bizarre, the impossibly odd.
Which is why scientists so often find themselves using it.
“Like Alice in Wonderland,” writes expert in human molecular genetics, Chris Gunter, “researchers in the molecular genetics of cancer may feel that each discovery leads to a ‘curiouser and curiouser’ set of questions.”
There are more things in heaven and earth than are dreamt of in our philosophy. Things that happen on another plane, without us even thinking about them. Unless, that is, we are physicists in Siberia. Physicists in Siberia think about the unknown a lot, because, let’s face it, what else is there to do out in Siberia?
Atoms change all the time. And when they change type, they give out energy, but we don’t see it because our personal world is small,when all is said and done.
But a Jesuit priest was of the persuasion to ask questions about them. In 1909, Theodor Wolf stood at the bottom of the Eiffel Tower, Paris, with a little gadget he had made. It was called an electrometer. And he measured the energy coming from changing atoms, all the way up to the top.
And at the top, the energy was far higher than at the bottom. And after some hefty mathematical calculations, the priest concluded that the energy was coming, not from below, but from the sky scape above.
So what was the source of this energy?
Could it be the sun? Only a crazy scientist would think of taking a balloon to 5300 metres during an eclipse to rule this out. But in 1912 that’s just what Austrian-American physicist Victor Hess did. The energy, even without the sun, increased fourfold at that height.
Curiouser and curiouser.
“The results of my observation,” Hess announced in his presentation speech for the Nobel Prize- “are best explained by the assumption that a radiation of very great penetrating power enters our atmosphere from above.”
Unseen energy from above. Cosmic rays. We surf dangerously close to pseudoscience, do we not?
No, we do not. Thanks to the Fermi Gamma-ray Space Telescope, which has spotted the origin of these incredible bursts of energy. The ‘rays’ are actually just really high-energy particles which plummet into our atmosphere, colliding with the natives to produce great showers of energy. They’re called air showers.
And Fermi confirms the particles come from the supernovae of massive stars.
We have toured Paris and ballooned through an eclipse: best to head to Siberia for the conclusion of today’s rabbit hole. in Tunka, the middle of nowhere, a seeming wasteland, are a lot of very happy physicists. Because they have set up 133 sensitive light detectors. Their job: to detect the light created by air showers on dark, clear nights in the wastes of Russia. And in this way, to work out what direction the rays are coming from, and what type and energy they are.
I think, judging from the pictures on their website, that there is nothing happier than a scientist down a rabbit hole.

A wonderful tour d’hole. Thanks Kate, now I’m back to wondering if I need the tinfoil hat to protect me
We should stand at the bottom of the Eiffel Tower bawling “Take cover!” Sidey.
and wearing those snazzy tinfoil hats
Just when we think we know a bit of the heavens and earth, those pesky scientists keep us coming back for more. Most Excellent.
The eternal questions, Lou. Refreshing, isn’t it?
I always wonder about the first explorers willing to take their sailing vessels to the edge of the ocean in a flat sea…were their rabbit holes going to lead them to the edge of danger and then drop them off a cliff? The smile on the Russian scientists’ faces does make me smile in return.
I have another blog site I commissioned several years ago and have done nothing with I called “down the rabbit hole”–I wasn’t ready to blog, but I loved the title and thought of exploring odd bits of story, like my conversation yesterday. I was invited to go to an old cemetery with a friend who collects EVP’s (electronic voice phenomena) and I told her there was no way I could handle that. Her entire conversation with me was about the energy she measures. There are “rabbit holes” and there are “rabbit holes.” And there are all kinds of people out there measuring the unseen.
I wouldn’t have been able to handle that, either, Debra. It begs the question, is it wise to investigate every question? Questions got us to a realisation of nuclear power and its destructive capabilities, and soon the scientists were in thrall to the politicians. But questions – measuring what was thought unmeasurable – are an enthralling business.
Eeeeexcellent response, Kate. I have always been fascinated by how energy can be detected and measured.
Ooooh, lovely to hear that voice of yours, Andra. Been following your adventures avidly.
I think what got me about this was the More Things In Heaven and Earth factor. Look, I mentaly tick off on my ticklist, there’s another thing they didn’t see for millennia that they can see now….wonder what’s still out there…
I was in Lewis Carroll mode today.
Now that sounds a stunning first line of a novel. It’s enought to send anyone cybersprinting towards your blog in an unholy scramble to find out what you’ve been up to.
Gosh, that terrain reminds me of West Texas near the Big Bend by the Mexican border. Who knew we had our own Siberia? Except it really doesn’t snow to speak of.
Fascinating post Kate! Buying a tin hat sounds like the prudent thing to do 😀
Last week, a crossword puzzle clue was . . . “Inexpensive hat material.”
Answer: TINFOIL. 😀
If you don’t already, you should take up knitting. You have an amazing skill to be able to knit together so many threads and not have it all unravel down a rabbit hole …. tee hee 🙂
I probably should not say what am about to, as it could be misinturppreted. But. Some scientists make for the biggest idiots. Akin to chasing a fart in a wind storm.
I love this. It is certainly an imaginative way of looking at a rabbit hole! So all we need to do if we need more radiation is go and start a few more supernovas? Good to know.
I do love the way the Russians don’t bother to get elaborate on basic stuff like stands. I bet that if the Americans were conducting the same experiment those wooden platforms would have been replaced with something costing megabucks – which probably wouldn’t have done the job as effectively.
Entertaining, informative and inspiring. Just the kind of post I want to read on Sunday morning with my coffee. Thank you.
