# Lunchtime Photo

It’s lunchtime on Christmas Eve, but I have no Christmas-themed photos to share with you. However, I’m sure we all agree that Albert Einstein’s theory of relativity is a timeless holiday classic, and it turns out that I do have a relativity-themed picture for you. I snapped it a couple of days ago, so I got it just in the nick of time.

Eagle-eyed readers with good memories will recall that explaining relativity is one of my pastimes, but I’ve long had a pet peeve about it: namely that general relativity is routinely explained using a timeworn picture of a trampoline to describe how gravity works. I’ll spare you the long-winded reason why this annoys me (it’s here, if you’re interested), but the nutshell version is that (a) it provides a completely incorrect impression of what’s actually going on, and (b) the real explanation of what causes gravity is both easier to understand and far more interesting. However, I have come up with a timely compromise. Behold the general relativity spider web:

Check it out! It’s a trampoline-shaped spider web! The reason it’s trampoline-shaped is that the spider has erected some extra web filaments that pull the center outward, thus providing the equivalent of a non-Euclidean spacetime in which the geodesic bends toward the center.

Don’t worry about what that means. It’s bafflegab. The point is this: If you want to write about general relativity and you insist on using the trampoline metaphor, you have my permission to use this photograph anytime you like. In fact, I insist on it. I further insist that you explain the warpage of spacetime using the metaphor of a gigantic, invisible, relativistic spider. Deal?

And what the hell. Here’s another photo of the spider web. It’s taken from a slightly different angle and at a slightly different time, and for some reason this tiny change converts it from a timeless black-and-white image to a surprisingly moving color rendition that evokes the inexorable motion of the spider’s prey toward the center of the web. Fascinating, no?

### AN IMPORTANT UPDATE ON MOTHER JONES' FINANCES

We need to start being more upfront about how hard it is keeping a newsroom like Mother Jones afloat these days.

Because it is, and because we're fresh off finishing a fiscal year, on June 30, that came up a bit short of where we needed to be. And this next one simply has to be a year of growthâ€”particularly for donations from online readers to help counter the brutal economics of journalism right now.

Straight up: We need this pitch, what you're reading right now, to start earning significantly more donations than normal. We need people who care enough about Mother Jones’ journalism to be reading a blurb like this to decide to pitch in and support it if you can right now.

Urgent, for sure. But it's not all doom and gloom!

Because over the challenging last year, and thanks to feedback from readers, we've started to see a better way to go about asking you to support our work: Level-headedly communicating the urgency of hitting our fundraising goals, being transparent about our finances, challenges, and opportunities, and explaining how being funded primarily by donations big and small, from ordinary (and extraordinary!) people like you, is the thing that lets us do the type of journalism you look to Mother Jones forâ€”that is so very much needed right now.

And it's really been resonating with folks! Thankfully. Because corporations, powerful people with deep pockets, and market forces will never sustain the type of journalism Mother Jones exists to do. Only people like you will.

There's more about our finances in "News Never Pays," or "It's Not a Crisis. This Is the New Normal," and we'll have details about the year ahead for you soon. But we already know this: The fundraising for our next deadline, \$350,000 by the time September 30 rolls around, has to start now, and it has to be stronger than normal so that we don't fall behind and risk coming up short again.

Please consider pitching in before moving on to whatever it is you're about to do next. We really need to see if we'll be able to raise more with this real estate on a daily basis than we have been, so we're hoping to see a promising start.
