Incredible audio shows what WWI sounded like when the guns and bombs just suddenly stopped

It's both beautiful and haunting to hear the ceasefire silence at the agreed-upon 11th hour.

Much of World War I was fought in trenches.

On November 11, 1918, U.S.soldier Robert Casey wrote from the American front in Western Europe:

And this is the end of it. In three hours the war will be over. It seems incredible even as I write it. I suppose I ought to be thrilled and cheering. Instead I am merely apathetic and incredulous … There is some cheering across the river—occasional bursts of it as the news is carried to the advanced lines. For the most part, though, we are in silence … With all is a feeling that it can’t be true. For months we have slept under the guns … We cannot comprehend the stillness.

It was the 11th day of the 11th month, and the war was scheduled to end with a ceasefire at the 11th hour—11:00 a.m. exactly. It had been four years of bloody, brutal fighting in what would later be called World War I. (Ironically, the war that was dubbed "the war to end all wars.")

The sense of relief at the ceasefire had to have been palpable, and thanks to modern technology, we can get an idea of what it sounded like to have the constant gunfire, artillery shells, fighter planes and bombs just…stop.

The following audio is not a recording, since magnetic tape recording technology didn't exist in WWI. It's a sound recreation based on visual "sound ranging" recordings the military used to determine where enemy fire was coming from. Special units placed microphones in the ground and used photographic film to visually record the noise intensity of gunfire, similarly to how seismometer measures an earthquake.

The lines you see in the film below are vibrations from noises at the River Moselle on the American Front, which were interpreted by sound company Coda to Coda using meticulous research on the kinds of weaponry that would have been used and how far away they were, even taking into account the geography of the area.

The result is the sounds soldiers would have heard during the last minute of World War I. Listen:

The little bird chirp at the end really punctuates it, doesn't it? Beautiful, yet haunting.

The fact that there was an exact minute when opposing forces agreed to lay down their arms and then did so is a bit surreal. If you know you're going to stop shooting, why wait for a few hours and keep shooting one another? Why not just say, "Stop, we're done now"? Communication took time and the various forces needed to be informed of the ceasefire agreement, so it makes some sense, but still. The armistice agreement was signed six hours before the ceasefire. In those six hours—when peace had already been agreed upon—3,000 soldiers were killed. Talk about senseless deaths.

Of all the things humans have devised and systematized, war is probably the weirdest. Leaders get into disputes over political or geographic particulars, and then one says, "I'm going to send my people to kill your people." Another responds, "If your people kill my people, then my people will kill your people." Then the worst of human atrocities are perpetrated by people who would normally never dream of doing such things to one another until, at some point, they've all have had enough of the senseless destruction, the leaders come to some kind of agreement and say, "OK, our people will no longer kill each other. Good talk."

Of course, it's all a bit more complicated than that, but at the same time, it's not. War as a concept is simply stupid and stupidly simple. Humanity in general does seem to have grasped the stupidity of it, as we've been making global progress toward a more peaceful world for many decades. But as conflicts ignite and violence explodes in certain regions, we feel the tenuousness of that progress, which makes peacemaking skills all the more valuable.

Twenty million people were killed in WWI, more than half of them civilians. Many of them died from famine and disease brought on by the conditions of war. This audio is a reminder that these things don't just happen—they are choices that human beings make. Destruction and diplomacy are both choices. Retaliation and restoration are choices. War and peace are choices.

We've tried choosing war followed by peace, many times over. Maybe we should try choosing peace without having to go through the stupid, senseless killing part first.

Let's talk about hummus for a second.

Yes, hummus. The smooth garlicky, lemony spread and dip that's a staple of both Middle Eastern and Greek cuisine.

Whether a Sabra fan or a Tribe enthusiast or a make-your-own purist, it's hard to find someone who doesn't like the delicious creamy taste of hummus.

Hummus also has a deep cultural significance. It's been bringing people together for centuries.

A group of people sitting around a bowl of hummus is a familiar sight basically anywhere in the world. There's just something about those blended chickpeas that brings people to the table — pita bread and baby carrots in hand — ready to smile and eat.

Kobi Tzafrir, a restaurant proprietor in Israel, knows all about the power of hummus, and he decided to put it to the ultimate test.

He's offering a 50% discount at his restaurant, the Hummus Bar, in Tel Aviv, on any meal shared between a Jew and an Arab. Why?

Here's a bit of background:

For hundreds of years, Arab Muslims and Israeli Jews have been at odds in a tense political and religious conflict. It's so complex and deeply entrenched in both cultures that explaining it would probably take all week. You can actually get a master's degree in it.

The biggest thing you need to know, though, is that this conflict isn't just a quibble. It's a cultural war that has claimed thousands of lives. In fact, recent outbursts of violence are part of what sparked Kobi Tzafrir's idea.

He thought that if he could get people together for a meal, they might realize they're not so different.

After all, pretty much everyone likes hummus.

"If you eat a good hummus, you will feel love from the person who made it," Tzafrir said in an NPR interview. "You don't want to stab him."

Can a dip solve a historic and bloody conflict? Maybe. Maybe not.

The idea is an experiment that has, so far, granted at least 10 pairs of people a discount during the last month. It's a small start, but for Tzafrir, the important thing is demonstrating to his country and the world that things can change.

"We hear a lot of extremists on the news, on Facebook, on TV, and it seems like everything here is very bad," Tzafrir told NPR. "But I wanted to show that everything here is not so bad. Things get out of proportion."

Tzafrir has been getting praise for the idea from people as far as Japan, and he says that business is up by at least 20%.

But does "food diplomacy" even work?

Well, that depends. Have you ever sat down for a meal with someone you disagreed with? Even if you didn't come to an agreement, you probably both shut up for a second to eat, right?

Believe it or not, even that little piece of common ground can be a key factor in changing people's minds.

In 2011, Psychology professor David Desteno wrote about the power of common ground in The Boston Globe:

"One key factor that shapes our judgment is a surprisingly simple one: how much we see the person we’re judging as similar to us. New findings are suggesting that this similarity doesn’t have to involve anything as obvious as being part of the same group or family. It can be something as subtle as wearing similar colored shirts or wristbands. In fact, in a new experiment, my colleague Piercarlo Valdesolo and I have shown that morality can be influenced even by simply tapping your hands in time with someone else’s."

We've already seen food's ability to peacefully cross cultural barriers.

When Thailand and South Korea wanted to improve their standing with other countries around the world, they started with food. Bringing their cuisine to a wider global audience helped people around the world get to know a little bit of their culture and, in turn, improved global relationships.

And remember President Obama's Beer Summit? Or the Wichita Police Department's recent BBQ with Black Lives Matter activists? Sure, these things obviously didn't solve every race problem in America, but bringing people together peacefully is a lot better than yelling, cursing, and killing.

The Arabs and Jews who sit together at Hummus Bar will probably experience more than just a discounted meal — and that's the point.

At that table in that restaurant ... there will be peace. And there will be hummus.
