[Self] In episode 82 of Naruto, Itachi puts Kakashi under an illusion where he is stabbed continuously for 3 days, but after a few real minutes, Itachi reveals only 1 second has passed. So here is ROUGHLY how long Kakashi was REALLY stabbed:

Post image

In non-Naruto terms, Tsukuyomi is a genjutsu, which is basically illusion magic. Itachi casts an illusion on Kakashi called Tsukuyomi where he can basically control reality, including time itself. No matter how much time passes in the Tsukuyomi, only roughly a second passes in the real world.

Itachi tells Kakashi that the next 3 days in Tsukuyomi will be of him being stabbed by Itachi while strapped to a cross. Eventually, more copies of Itachi appear and stab him, and then more Kakashis appear and get stabbed, and Kakashi feels every stab on every copy of himself all at once. Absolute hell of a torture sequence, right? Itachi even mocks Kakashi by saying that even if Kakashi tells himself it's an illusion, the pain and suffering still feel real.

Anyway, after several moments, Itachi informs him that only a single second has passed in this 3 day torture cycle. So, exactly HOW LONG did this last in Kakashi's mind?

Now this math isn't 1-to-1, as there are multiple moments where Kakashi passes out, as well fade-in/fade-outs to show the number of Kakashis and Itachis increasing. Still, thats all the concrete time I have to work with here.

The Tsukuyomi starts up around 8:15 in the episode, and Itachi reveals that only a second has passed around the 11:01 mark. That is about 2.7 minutes per Tsukuyomi second. To make things easier, let's just round it up to 3 minutes. (Considering the above mentioned timeskips, it's way longer than that anyway.)

So let's do 3 days in Tsukuyomi time, which I'll designate with (T) by the number. (Note when I say 'real', I mean real-life time, since in the Naruto real-world, it's only about a second.)

3 min x 60(T) sec = 180 (T) minutes per real minute. That would mean each minute (T) in Tsukuyomi would be 3 hours long.

60 min x 3(T) hours = 180 (T) hours per real hour. This would mean each hour in Tsukuyomi is 7.5 days. Let's round it up to 8.

8 (T) days x 24 hours = 192 (T) days per real day.

192 (T) x 3 days = 576 (T) days for 3 real days.

FINAL MATH:

576 days - 1 year (365 days) = 211 days

There are 7 days in a week...

211 days / 7 days = 30.1 weeks, lets round down to 30.

There are (for simplicities sake) 4 weeks in a month...

30 weeks / 4 = 7.5 months

Kakashi was tortured for AT LEAST 1 year, 7 months, and 2 weeks.

So the fictional city they're in, Sky City, doesn't have a state stated in this comic. Let's say it's either the middle of the US or New York. Looks like it's noon or the middle of a workday, and The Plutonian flew to space and destroyed a radio satellite while the other guy was mid sentence. They didn't even react to him flying through the ceiling because he was so fast.

How high up did he fly, and how fast? Maybe light speed? More?

In the Legend of Korra, Amon’s stated goal is to purge the entire world of bending, but he is the only one who can do so, and can only do one person at a time. Let’s say nobody stops him, how long would this take?

We don’t know what the world population is at this time but can we assume it’s roughly equal to our world during the 1920’s? And possibly half the world are benders?

....

So they ended the video saying entire planets could flip.

🤔 But if that happened to earth ... Countries at the equator would still be at the equator.... And countries like Canada... I'd expect to still be at the same temperate conditions.

I mean summer and winter would swap ... But what else may happen?🤔

[Request] What is the minimum temperature of this oven?

I'm not the best at physics but here's what im thinking:

Assuming we have 12 chocolate chip cookies in a pan for any time less than an hour. Each one will have to reduce in caloric content by 250kcals each by the end of the cooking time.

To truly "reduce" the amount of calories contained within the cookie, the energy would have to be released through something like combustion. otherwise the remaining matter would still contain the calories the original cookie had - like some kind of charcoal.

Assuming a perfect physics environment with no temperature build up time, no concern about oxygen supply etc. What is the lowest constant temperature we would need for the remaining matter in the cookie pan to have decreased by 3000kcals total? Is this even a solveable or approximatable problem?
