My son sent me this. My immediate thought based on nothing is that it’s unsurvivable regardless of the depth.

[Request] What is the longest one could drive without changing lanes?

5 Upvotes

A job I had awhile ago had a fun part of the commute. On the way home, once I merged onto the highway, if I got into a specific lane, I could follow that line for about 15 miles. It would merge me onto the interstate and drop me off on the right exit without ever changing lanes.

I took that route again tonight after a date night and my mind mused…what would be the longest stretch in the world where you could get into a lane and never change lanes?

Rules:

  • No circles (e.g. multiple times around a roundabout)
  • Assume no construction or lane blockages/closures
  • A lane must be separated by painted lines, either dashed or solid. If a road ends to a non-painted street, that lane ends.
  • A lane change requires driving over a dotted or straight line. If the lane exits to a different road, but it continues in a single lane without merging lanes, that is allowed.

[Request] How much would 12 French Francs from 1926 be worth in modern day Australian dollars?

2 Upvotes

I'm reading The Sun Also Rises, and its mentioned that the whiskey and soda the characters but from a bar costs 12 francs. Would that have been a lot of money? Not quite a straightforward currency conversion as both France and Australia use different currencies than they did when the book was written.

69 kilograms of computer storage would weight around 8600000000000000000 terabytes. [Self]

The weight of each bit is just one electron and one electron weight around 9.1*10-31.

(69kg)/((9.110-31)kg/electron)=7.581031 electrons

This is also the number of bits, to convert to bytes. We just divide by 8 and get

9.481030 bytes or 7.8 million yottabytes(8.61018 terabytes).

This is just an approximation and I was being generous in the calculations, please correct me if i got something wrong, it is very possible since I am just a child and English is not my first language.

[Request] Could 650 million people have visited the Kumbh festival in 45 days ?

0 Upvotes

In the recently concluded Kumbh Festival in India in 2025 it was said that almost 650 million people visited one place (City of Prayagraj) in 45 days.

Now the people came to the river banks, did the rituals and went back. some people stayed 1 night at the place. Some people stayed for 2 nights whereas a lot of people just came in the day and did not stay and went back the same day. There were some people who came stayed in the car and did not book hotels or stayed in open grounds

Is it possible that 650 million people visited in for 45 days? Is it possible logistically for transport, stay to manage this crowd

some sources of the info
