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?

SIX TRUTHS

Reclaiming power from those who abuse it often starts with telling the truth. And in "This Is How Authoritarians Get Defeated," MoJo's Monika Bauerlein unpacks six truths to remember during the homestretch of an election where democracy, truth, and decency are on the line.

Truth #1: The chaos is the point.

Truth #2: Team Reality is bigger than it seems.

Truth #3: Facebook owns this.

Truth #4: When we go to work, we're in the fight.

Truth #5: It's about minority rule.

Truth #6: The only thing that can save us is…us.

Please take a moment to see how all these truths add up, because what happens in the weeks and months ahead will reverberate for at least a generation and we better be prepared.

And if you think journalism like Mother Jones'—that calls it like it is, that will never acquiesce to power, that looks where others don't—can help guide us through this historic, high-stakes moment, and you're able to right now, please help us reach our $350,000 goal by October 31 with a donation today. It's all hands on deck for democracy.
