You and the professor have driven your DeLorean back to the past to fix issues with the spacetime continuum caused by your time traveling. But another DeLorean appears with older versions of you and the professor. The professors panic and explain that the universe could collapse now that you’re both in the same time and place. Can you merge the timestreams and travel home? Dan Finkel shows how.

"If the earth were flat there would be no way to solve this riddle"
Flat earthers : 💀
If we’re going to violate the time part of space-time with the premise, let’s break space as well. It’s wormhole time!
Exactly my thought!!!
if? The riddle makes earth round originally planned to time travel happening?
222 👍
The fact that we don't have any time traveler is proof that the earth is flat 👍
This has been the only riddle I’ve been able to solve without pausing or researching. Love these riddles
Same
Yep, same here. Feeling smart for once, haha
I would have been able to solve it but the way he explained it confused me so I was just sitting there lagging until the explanation. Or maybe the space time continuum is messing with me
Same
Same, though I got the South Pole correct for the wrong reason.
"Can you solve..." title made me clicked immediately
Same
Yup same.
Same, even though the answer is no
That's how clickbaits work ✅
rubix's compleks
4:16 I love that reference to the other time travel puzzle. Good job, TED-Ed!
Oh yea
I imagine the professors from both riddles being rivals over whether cars or portals work best.
Beat me to this same comment :D
I guess he never actually got back home 😔
@@zingerific8209 nope
This is really great,they should make a movie based on this
And I predict that it would be very successful that it would have two sequels
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.
There should also be a broken clock tower
@@gorochu4287 both for finding each location
And a big train time travel machine should also be added.
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
Facts
Oh I was thinking it's something to do with the curvature of the Earth, but didn't think of the poles cos they said not magnetic oops-
@@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".
did anyone else notice the other time traveler from the triangle nodes riddle at the end of the video?
7-6-23
Yeah, cool Easter Egg.
@@michaelschlem2849 why'd ya put the date next to your reply?
@@SysFan808 7-6-23
Cause he and i are time travellers
same
I understood that reference
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.
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.
@@tylerduncanson2661 oop not another time loop like the tv show dark!
I think the future guys are from the timeline where the past guys didn't think about it at the time...
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
Congratulations
Finally, a new riddle! Have been waiting for a long time for one. Can we have one every week? I just love these riddles that you came up with.
yeah
I’d love that
One of the only Ted Ed riddles I managed to solve on my own. Always the best feeling
It’s a good thing RUclips’s staff is also helping fix the space-time continuum.
Always give time to pause and allow us to think about it, really enjoy the riddles.
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.
This is the first TED riddle I managed to solve on my own!
The bridge riddle 😭
This was the first TED Ed video I actually solved on my own, that was an awesome feeling.
Finally a riddle after months🔥
glad to see Ted-Ed is still making riddle videos.
1-check if you have green eyes
2-ask the time gates to leave
But not before saying OZO
The fact that they made this right when Back to the Future the Musical just went into previews on Broadway is so cool
"Can you solve--"
"No!! But I will watch it anyway"
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?
A man builds a house with all four sides facing north. A bear walks by the house. What color is the bear?
@@kingwolf3044 no colour - i don’t think any live there
@@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.
I literally only click these videos for the story
*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?*
Pepperoni pizza!
14.52 squared!
Whit! since it happened at the poles
Well, he's probably dead since bears are much faster than humans and running from them triggers their predator instincts...
This is the first time I have ever been remotely on time for a Ted ed video
This is only the second time I was able to solve a riddle before Ted-Ed told me the solution. Great riddle!
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.
As soon as I heard the directions, I loved this puzzle as a kid.
You mean you… time travelled to when you were a kid and showed yourself the puzzle? The video came out a day ago lol
@@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.
I love how almost every Ted ed riddle has something relating to another riddle at the end.
I thought this was about time travel paradoxes...
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!"
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)
4:17 I love the easter egg but wish this would be a sequel or some form of crossover just to make it more interesting
I thought that Slate Kanoli was going to be involved!
I love the Ted Ed riddles
Great Scott! This was heavy. And not due to any problems with the Earth's gravitational pull.
This the only TED-Ed riddle i managed to solve
The other past riddles, some I could solve but still understood most of them. This one here was quantum mechanics to me 🤣
Great Scott, a BTTF reference!
One of the very few riddles on this channel which I was able to solve immediately without help.
this is one of the first riddles ive solved on my own!
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
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?
If my car needed a riddle to operate I'd definitely walk without issues whatsoever
Love these riddle videos amazing
1:49 *professors vanished*
Me: “Welp imma head out”
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?”
Me: makes the radius of the circle on the south pole as small as possible
Car: *turns into a helicopter*
Wow, I hope they make a movie out of this!
I wanna see this version of back to the future!
That "Great Scott!" gave me goosebumps.
The fact I was actually able to figure out the solution on one of these for once
I've known this one since I saw it in a magazine when I was a kid in the 80s (not including the BTTF trappings).
I love this video!
Although I am sad not to see the international metric system
Finally a new riddle
More riddles!!!
first riddle i new the answer too, i love non euclidian geometry so i knew that on a sphere you can draw a triangle with 3 right angle corners
MORE RIDDLES LETS GOOOOOO
I love these!
this is the first ted ed riddle i got right...😃
Yay ted ed riddles
Whoa, this is heavy!
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.
Great Scott!
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!
After so much time... Finally... I could solve this riddle....
Brilliant is real cool it is soo good cant stop researching on it
First time I've actually solved it without pausing, and on 2x speed
This is the first time I actually got the solution. And it didn't take that long.
glad I got this one first try
Finally! A Ted riddle that doesn’t contain the words “prime number” in the solution!
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?
That's solving a different question from the one the video asks.
Yes, but the problem states the two paths must be at least 100 miles away.
"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."
The first riddle I've actually solved!
I thought it was originally gonna be related to triangles, but this makes more sense.
As soon as I saw the mile in each direction, I knew what this was gonna be about
This is definitely one of he easiest riddles that have been presented on this channel. Still enjoyed it though!
2:48 net work done is zero and displacement too 😂😂
Let me guess? This is a Riddle that has nothing to do with a Car nor Time Travel, but in actuality is about having to do Math?
It's more of a simple lateral thinking puzzle. The math is just their finishing touch.
Yup, they never have any actual riddles, just Math problems with a story around it. Might as well be asking at what time will two trains meet.
This one is actually more of a geographical solution, with a small touch of math.
@@AmTrFilms Can't something be a riddle AND a maths problem?
@@Inkyminkyzizwoz Yes, but I don't think that simply giving variables in equations names and a backstory qualifies it as being a riddle.
We need a prequel riddle like we got how the blob got on the Earth
posing a "what are the rules of time travel" thought experiment with someone else (or future you) having "the same idea from somewhere else on the timeline" (like this one starts with) caused *yelling fights* in my office.
I immediately went ‘GO IN A TRIANGLE’ 2:31 GUESS WHAT
4:16 Time travelling intern randomly passing by.
4:16 the person with the glasses is from the other time traveling riddle. Thought we wouldn't notice, but we did
I’m so pleased with myself, I actually got this one 🎉
Congratulations
Well, I figured out that it was going to be a north pole and south pole kind of deal. Didn't figure it out beyond that, but at least I got a little bit!
OMG was I acutally early for a ted-ed riddle???? wow
The question: *very popular interview question*
TedEd: imagine a time travel paradox.....
Understanding the question is harder than the actual solution
The cameo of the other time traveler from a different video got me! 😂😂
#TedRiddleCinematicUniverse
Clicked so fast ngl
Lemme rizz up
4:00 "The small circles aren't actually practical to drive."
Well, we are driving around the North and South poles as if that's perfectly normal...
I saw "Can you solve...", and my finger clicked it before my brain knew what was going on.
I finally solved a TedEd riddle!
Since the cars hover, could you theoretically do both laps on the north pole, a mile apart vertically?
I love how the professors werent implied to be revived lmfao
love this bttf reference
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?”
Transparent!
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.
a time travel riddle and a roast at flat earthers? BRILLIANT!
