What if everyone jumped at once?

What would happen if everyone on earth stood as close to each other as they could, jumped, and landed on the ground all at the same instant?

This is a masterclass in answering the question they asked, rather than the question they meant.

[xJarlaxle]

Most important take away from this is: the wizard who teleported everyone to Rhoad Island is an asshole

[jonahweiss]

So this begs the question, where is the best location on earth to teleport everyone to minimize deaths

[mrquackadoodlemoo]

I like how 7, 000, 000, 000 people jumping in one spot did nothing to the world, but getting those 7, 000, 000, 000 people out of the one spot is what would cause the chaos.

[Naz-jctp]

My biggest takeaway is that if we’re ever gonna do this, the teleportation BETTER be a two way trip.

[kevinpierce]

“Who can stop you? All the cops are in Rhode Island.” That is one of the best lines I have ever heard.

[daviddelille]

Everyone who was in surgery or on life support probably died soon after they were teleported. Everyone who was deep diving experienced rapid decompression. Even assuming clothes would be teleported, quite a few people arrived naked (those who were showering, taking a bath, etc.). About a third of people arrived asleep.

[ClutchCps]

It's funny how the action of everyone jumping at the same time wouldn't cause some post-apocalyptic event, but the aftermath of getting everyone to the same area in the first place would.

[Micha-Hil]

I love how half of this video isn't even about the jumping simultaneously thing, it's about how would people live if they were suddenly and abruptly all brought together with no reason

[DiamondAxeStudiosMusic]

As someone born and raised in Rhode Island, it is genuinely disarming to hear anyone outside of our state talk about ANYTHING specific about it.

Also you know what? Yeah. I never really thought about it, but T.F. Green DOES have exceptionally nice bathrooms for an airport.

[hkumar]

Everyone dies. Just not in the way you were expecting.

[Pabloable]

Thomas: "What would happen if everyone got together in one place and jumped?"
Randall: "We wouldn't be heavy enough to affect the Earth's orbit."
Thomas: "Damn, I guess nothing would happen."
Randall: "That's not what I said."

[PtylerBeats]

It’s fascinating to know that simply bringing everyone together would tear us apart.

[BlastedOblivion]

The most surprising part of this is that the entirety of the human population can fit in an area the size of Rhode Island.

[thegamesforreal]

Fun fact: Assuming a person landing after their jump makes a pulse of sound at about 60 decibels (tested it myself with my smartphone mic), then 8 billion people doing so at the exact same spot would correspond to a sound of 156 decibels, which is about 4x louder than a jet engine firing at maximum throttle at point blank range.

I reality the noise would not be that loud because the crowd is spread over a massive area and not condensed into one point, so the noise from the outer edges of the crowd takes a while to reach the center of the crowd, and vice versa. You can still expect a short but deafening blast of noise when the 8 billion people land, though. People not close to the edges of the crowd are at risk of hearing damage from this.

[RedneckRough]

My favorite is the Japanese person going “Oh, I forgot to put out the fire.”

[WalnutBun]

I love that every video on this channel inevitably turns into "and everyone died, the end".

[AGoodLittleSub]

Of all "Uhm, actually" style moments I've seen until now, the cellphone part honestly is my favourite I think.

[WhatDoesMyChannelNameMean]

I have to disagree with 1:27 "A cell phone comes out of a pocket. Within seconds, the rest of the world's seven billion phones follow." That would never happen. Everyone under 30 would already have their phone out the entire time, recording the jump and livestreaming it even if no one is watching because everyone else is there too and is filming it on their own phone.

[iabervon]

This reminds me of last Monday, when a lot of people managed to get to northern New Hampshire, not far from Rhode Island, in time for a scheduled event, and then were up to 12 hours late getting home due to traffic. Fortunately, the eclipse wasn't so popular that society collapsed while they were away.
