Back to the Future movie time travel quote from Dr. Emmett Brown: "Don't worry. As long as you hit that wire with the connecting hook at precisely 88 miles per hour, the instant the lightning strikes the tower... everything will be fine."
Finally a new riddle! I appreciated that this one was different than the advanced mathematics that seem to have become de rigeur for the channel. Let folks' whose strengths lie in other areas feel like they have a shot at solving every once in a while! At least for this one I thought "gotta be something to do with the Poles" - any of the super intense math ones I'm just watching for entertainment purposes only 😅
My mind went for the north pole. But I saw that third rule saying it's about geographic directions and not magnetic and I thought it meant you can't use the poles
@@NabeelFarooquiThe reason they said that is because, if you use a compass, it doesn't point at the "North Pole". So the compass points at "magnetic north" and the actual top of the Earth is the "true north".
The unfortunate thing, is if you had time travellers go back to the past to do the same thing you did, that means paracausally whatever you did was not enough to stop Riff from becoming a tyrannical ruler, since if you did stop it, it would have been not a problem that they would have needed to solve.
Except they should make it more realistic. Like how going at 88 mph is required for the flux capacitor to work. They didn't even mention the capacitor which is what makes time travel possible.
I’ve watched every Ted-Ed riddle on this page. And this is the only one I’ve been able to solve on my own and I was actually able to solve it almost immediately
I'll be honest; I couldn't help but give myself a high-five to see what would happen. Would I have/Will I both time explode, would I time merge, or would everything else time explode or would time itself collapse? I would need to know. So I doubt I would have noticed the professor poof away or that the timeline needed to be fixed. Sorry everybody but good news, you are reading this so I never get the chance to time travel.
No, nothing like that. Your cells are constantly being replaced with new cells, especially when it comes to skin. So the skin cells on your older self's hand are not the same skin cells on your younger self's hand. You'd just have matching DNA. That's all. Hardly any different than giving a high-five to your twin.
@@jerryhook5906 You calling me some kind of ship of theseus? Thems fighting words. Wait, what if my older self -murdered- suicided my younger self? Would that break time?
@@jiwon.p It's unclear why this is even a problem; if the older one is around, they can just tell the younger one the answer. As for the fact that no one has ever seen a time traveller before and lived, perhaps the timetravellers are made to dress for the era they are going too before leaving and use cloaking technology to remain unseen, making time travel is more of an attraction for tourists. People who claim to see ghosts or aliens may be catching hiccups or technical difficulties with the invisibility technology, like spiderman. Or the timegate theory thing, if a time gate is built the earliest point in time that can possibly be travelled back to using the time gate is the moment it was finished making it impossible to have time travellers before the timegate is built.
One's at the exact north pole. 1 mile south of it you turn east, but no matter how far you drive there, it'll still be 1 mile north to the north pole. The second is just above the south pole, where driving east will send you into a circle; it should be placed where that circle would be 1 mile. Roughly this would be at 1 mile /2pi, or about 0.16 miles north of the south pole (the direction doesn't matter, just pick the part with the best surface); you start 1 mile north from there. Possible problems: - you must make sure the surface is navigable. Particularly on the north pole, it has to be well frozen to support the car, aside from all issues of snow, ice etc. - at the south pole we get a second problem. Here we must drive a full circle with a length of 1 mile, and a radius of .16 miles, or about 280 yards. If we're also supposed to get a certain speed with that (88 mph), given the ice and all that, this might pose some difficulty. Bear in mind, in both cases the journey east is not in a straight line. You need to constantly steer on the same circle. So it most likely will require preparing a proper road. Finally, we'll also need to stock up on some weaponry and money... getting to both poles for a rather insane mission may require both.
This one is fairly obvious. It’s the same as the old riddle: “A man walks two miles south and three miles east. He shoots a bear and then walks two miles north, only to arrive at the same place he started. What color was the bear’s fur?”
I remember a similar riddle: an explorer walks a mile south of his base camp. Then he sees a bear, screams, and runs a mile east. Finally, he walks a mile north, back to his base camp. What colour was the bear?
@@emeraldnickelAnd Antarctica is so damn cold that even a polar bear would die of hypothermia there. And the answer to the original, is white, but could be a trick as it was never specified it was alive, so could be an unfortunate brown bear though it would be a good idea to go there.
The answer to the riddle was easy enough, but it raises more questions. How are you going to transport the Deloreans to those two locations? Do you have time to transport them? How long do you have before you disappear? Will they even function in those environments? Is the professor restored after you merge the timelines?
This riddle was easy to solve once you read the third rule about the directions not being magnetic, immediately realize it had to do with poles and the rest was child's play.
Usually I give up trying to solve the riddles myself because I don't want to pull out paper and figure out the math. But I heard this riddle and was able to just happily go, "oh, you use the poles!"
*The original version of this puzzle goes like this:* *A man walks a mile due south from his campsite.* *He encounters a bear, and immediately runs a mile due east. The bear is gone, so he then walks a mile due north to his campsite. What color was the bear?*
@@dawsonsawyer4726 I had a puzzle book that said a hunter leaves camp and tracks a bear ten miles die south. The bear then turns and the hunter tracks the bear ten miles due east. The hunter then shoots the bear and drags it back to camp, a distance of exactly ten miles. The question is, what colour was the bear? It was one of my favourite riddles as a kid. So not exactly the same.
Couldn't we just drive to the South Pole and do the whole sequence flipped? If it's the geographic and not magnetic North isn't it arbitrary whether we actually start North or South as long as we complete the circle in order?
Kinda easy if you know that lines of latitude are circles. I think the real question is how do they sync up their watches given that relativistic effects will mess with their Timing.
Finally a riddle I could solve because I learned years ago that you could get on the surface of a sphere a 180° triangle, which for all intent and purposes is what this video is asking for we to solve x)
1:23 i stopped here. Because i know where you can drive south, east and north, and end up in the same spot. At the pole. Im not bothering to watch the rest. I usually find the comment section more interesting
They can do the one that works for the South Pole so easily because it doesn’t have to be a line of latitude. It could in theory happen anywhere on a smooth sphere
"The universes would collapse now that you're in the same time and place" Me: *Drives a hook attached my car at 88 mph into a cable attached to a clock tower just as it's being struck by lightning*
Back to the Future movie time travel quote from Dr. Emmett Brown: "Don't worry. As long as you hit that wire with the connecting hook at precisely 88 miles per hour, the instant the lightning strikes the tower... everything will be fine."
Actually, I believe the easiest second point of start is the "limit" of the solution that the video proposes. Start at any place which is 1 mile away from the South Pole: going south 1 mile brings you to the South Pole; going east 1 mile is now just staying still; so driving north 1 mile is bringing you back to your starting point!
This is the first time I actually solved a Ted-Ed riddle and I knew of the solution thanks to a short from Action Lab (shorts) which talked about the shape of the universe and 2d people using lines to know the shape of their 3d universe.
I remember hearing this riddle in a much more simplified form when I was a kid. “You see a bear and you run away in fear. You run a mile south, a mile east, a mile north, and you see the same bear. What color is the bear’s fur?”
The end of BttF was Doc saying they don't need roads. To me, I immediately thought of the gate on a levitating platform facing sideways in the sky and using the flying delorean with open air
I have known this puzzle and knew that there are infinite solutions to this...but never solved it. Tonight i sat to solve this and it took me an hour to solve and finally i got the solution but i got till the part where we get the radius of circle having circumference of 1 mile but didn't consider it to keep equal to the distance on Earth's surface.
And the universe goes kaboom. This is based off of an old riddle, but it completely ignores the logistics. "Just" head to the poles? "Just" drive around? Let alone trying to sync everything and the complete lack of driving surface, how does one get their own body let alone a DeLorean to the polls "in a hurry"?
My solution was simple: The person traveling to the past should put their gate on the North Pole and the person traveling to the future should put their gate 1 mile north of the South Pole. When they travel 1 mile south, they will need to spin infinitely many times at an infinite rotational speed to travel 1 mile east before going north again. Assuming the car isn’t a fixed axis, any part of the car not along the axis of rotation will have infinite speed, therefore slowing down time relative to the earth around them and ending up in the future 😎
"If the earth were flat there would be no way to solve this riddle"

Thankfully, there are other potential motives. Maybe they just remembered that they forgot something back in the past and went to fetch it.
In this instance, they can at least take solace in the fact that the collision is the likely reason they failed.

Ted: Can you---
*Me: NEVER.* (said calmly)
Ted: But I---
*Me: NO.* (said calmly)
My solution was simple:
The person traveling to the past should put their gate on the North Pole and the person traveling to the future should put their gate 1 mile north of the South Pole. When they travel 1 mile south, they will need to spin infinitely many times at an infinite rotational speed to travel 1 mile east before going north again. Assuming the car isn’t a fixed axis, any part of the car not along the axis of rotation will have infinite speed, therefore slowing down time relative to the earth around them and ending up in the future 😎
