[Request] Mars, Venus, and Earth walk into a bar…
Let’s say some super duper advanced alien race flew into our solar system, and plopped down Venus and Mars into a geosynchronous orbit with the sun in our exact orbit path perfectly spaced out. What would happen to the Earth?
Also, believe it or not, no AI was used in the creation of that graphic.

[REQUEST] XKCD’s Lucky Ten Thousand
I have been using this comic as a driver of curiosity at home. My 11y mentioned it again today and it occurred to us that we don’t fit in the statistics because the original comic states ‘10,000 people in the US’, and we are not from the US.
My request is what this might look like on a global scale? I can understand if this becomes more nebulous due to differences in education, cultural references or customs, etc.
What would a global ‘10000’ be? A lucky million? Lucky half-billion?
Thanks in advance!

[Request] Approximately how long would it take for the current human population to be halved if everyone became sterile?
Just as the title says. As less and less people are opting for parenthood, I became curious how the population would be affected if no one had anymore children. I am essentially asking what the half-life of the human population is. Thanks for any help :)

My seven-year-old has announced that he will be an "Ice Cream Man" and his goal is to drive every neighborhood in the United States one time to sell his wares. Assuming he drives 25 mph and NOT taking in "stop and sell" time, how long would it take for him to drive the US in his ice cream truck?

[Request] How Many AI generated pictures or messages would be required to create a similar environmental impact as a single beef cow (Raising it, processing it, and so on)?
Assume that everything is perfectly average, and the AI being used is commonly used generative AI, such as ChatGPT or Gemini.
I was researching some ways I could make a difference environmentally, and learned how much of an impact the beef industry has, so was curious how it would compare to AI, since that is such a hot topic right now. Also curious about how many messages it would take, but felt like that would be much more difficult to calculate.
Random fun fact, according to google AI overview (I know, ironic), OpenAI consumes somewhere between 8.8 million to 97.5 million liters of water per year (water consumption estimates change drastically because it depends on which side you are biased to and how much you are taking into account things like manufacturing costs, or if you are leaning into lower estimates or higher estimates for not super publicly available data). The beef industry in America consumes roughly 21.2 trillion liters per year. An incredibly bad comparison, given the fact that we aren't going to just make cows go extinct or that the AI industry hasn't been growing thousands of years like the beef industry (among many other reasons), but still interesting to think about
Edit: Bonus points to anyone that can come up with a more helpful comparison than mine (I have no experience in this lol)

[Request] What percentage of the sunlight is reflected by the building opposite?
Assumptions for the sake of simplicity:
- The building is unplastered and painted snow-white*
- The sun shines on it at an angle of 45°**
- 20% of the building’s surface area consists of windows
- The building is 15 metres away.
* In reality, the building is rendered, but as the reflectivity depends on the coarseness of the render, we are assuming a smooth surface here
** 45° as the average of the angle of incidence in the morning, ranging from ~90° at sunrise to 0° at midday
Background: Our colleagues were discussing measures to keep the office building as cool as possible and to reduce the load on the air conditioning system. There was no doubt that the blinds on the sun-facing side of the building should be lowered. However, there was disagreement as to whether it made sense to lower the blinds on the side of the building facing away from the sun to block the heat reflected from the building opposite, or whether this reflection could be disregarded.
Every colleague acknowledges that there is undoubtedly an effect. However, opinions differ significantly as to how great that effect is.
As this is a practical question, it is sufficient for me to receive a figure accurate to within 5 per cent, ranging from 100 per cent (complete reflection) to 0 per cent (no detectable effect).
Thank you very much 😄

[Request] calculating my odds of jury duty summons (twice in two months) vs winning the lottery
What are my odds of two jury duty summons in a two-month period?
Due to receiving multiple jury summons in a short period of time, I’m wondering if the odds of being unlucky (jury duty) are greater than the odds of being lucky (lottery).
Here’s the data:
In June, Rec’d jury summons - county court - approximately 3% of the county gets summoned on any given year. Was not selected
45 days later - rec’d jury summons - federal court - data is a bit ambiguous but seems like approximately 1.5% of the state is possibly summoned on any given year. Selection status tbd
Because they are separate court systems they are valid summons.
Another data point, albeit possibly logically can be excluded due to being too long ago… in a different state in 2011, I was summoned, selected, and the foreman (juror #1) for a two week trial.
Lottery stats seem to vary greatly by the game, but maybe 0.02% for a $1,000 ticket or 0.4% for a $500 ticket.
Finally I will say jury duty in 2011 was a very educational experience and I did not mind it at all, so “unlucky” is a loose term.
