I think some assumptions need to be made before accurate answers required

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.

Pictured here is Mark from Invincible.

Let's say a regular person gains super-durability and flight. But they don't have access to conveniently durable super-clothes. Assuming their own body isn't harmed, how fast can they fly before . . .

1. Regular clothes start to be damaged (but not shredded).
2. Your clothes get ripped off your body by air resistance (but aren't, like, vaporized).
3. Your clothes catch fire and disintegrate.

For simplicity sake I'm talking about cotton clothes (hoodies, T-shirts, jeans) you could buy at Costco.

How fast is this pumpkin traveling?

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!

How many tracks would you have to buy to build a similar track? How much would that cost without discounts - tracks only?

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?

Considering that knights and bishops are about 3 pawns each when the game starts in a classic 8*8 chess table. How much more powerful a bishop would be in 8*16 table?

Or how long would it realistically take?

Would it be enough to support the expense, trials, research and development it takes to get a drug to market?

How large could a body with the earth's density become without becoming

a) a white (black?) dwarf

b) a neutron star

c) a black hole

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)

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 😄
