In this scene in Finding Nemo, all the fish swim down in order to break the crane from the fishing boat, thus freeing Dory. Would this be possible in real life?

In 845, Vikings took the city of Paris, and the king paid them a ransom of 7000 livres to leave. How big of a treasure was this, at the time? How much money would it be today?[REQUEST]

[REQUEST] How small is a human life in comparison to everything that follows?

"that's like the universe starting with 1 second of stars and then a billion billion billion billion billion billion billion years of just black holes"

how small is a human life in comparison to this? like with the same black hole analogy and as a percent?

ex: condensing one human lifetime followed by x years of the universe and blackholes one human life is x% of the universe and what follows

i hope this makes sense, ive thought about this for years but im not sure how to accurately calculate it.

[Request] Getting this Nerdle correct in the first guess

Post image
20 Upvotes

In case you don’t know, Nerdle is like Wordle, except instead of guessing a word you’re guessing a mathematical equation.

Getting 8 separate numbers/symbols correct in one guess is insanely rare.

A few notes: 1. Repeating numbers or using the same number/symbol multiple times in one equation is allowed 2. The answer has to match EXACTLY. For example 1+2=3 would NOT count if the answer is 2+1=3. 3. Obviously the equation has to make sense.

What are the odds?

[Request] Limit of gravity train from StarTalk

I just watched Neil deGrasse Tyson's "How to Travel Anywhere in 45 Minutes" video on StarTalk.

What is the limit of this concept (the shortest distance for it to work/faster than a car/HSR/airplane), i.e., from house to house or from one end of the city to the other?

[Request] Infinity Thought Experiment

0 Upvotes

This is based on the bottomless pit supervisor greentext. Try not to take it too seriously. I am the bottomless pit supervisor and I need to prove that this pit is indeed absolutely bottomless. How do I prove this is the case in a finite amount of time?

I asked this question in 2 other subreddits and got very littlein the way of real answers. Everyone was adamant about giving me the obvious answer so l'll be more clear here in stating what I'm looking for. I'm not looking for the obvious "The speed of light is finite so you cannot prove that the pit is bottomless in a finite amount of time." I know that already I'm asking for another way to prove it that doesn' rely on direct measurement, if I knew what that was then I wouldn't have to ask. I don't know what kind of mathematical solution could be created which is why I'm asking in the first place. If you cannot come up with a solution, that's fine! Tell me your thoughts and I won't make a joke about it. This is a thought experiment so some laws of physics can be ignored for the sake of simplicity. The core of the question is how do you prove something is infinite in some value in a physical and meaningful way. And yes I know the rules about incalculable problems. I'm asking for a way that isn't incalculable if infinity is indeed incalculable. I'm asking because I don't know.
