Yes, of course. They should be attached to something, e.g., two galaxies.

It is the same. Shortening of the moving object is shortening of the distance between two ends of the object, i.e., between two spatial points. In any case, distance between two points in a frame where they move is shorter than distance between them in a frame where they are at rest.

It is shortening of a distance between two spatial points. It happens at any speed and does not depend on what is there between the points.

This rock is constantly pounded by waves. I watch it wondering, how long until the "neck" will break.

When I choose to ignore a member's posts, their posts still appear in the Activities list, e.g., Is it possible to make them disappear from my view?

Or something out of focus moving on or in front of the camera lens.

In these videos, I don't see that the path is not parabolic and that it is at a constant speed.

If it is small, dark, and fast, the camera and we don't see it, except maybe a white spot on a tail. Its body jumps straight, but the tail might zig-zag.

I don't think it is an insect. Maybe a small rodent?

Sigh... My cheating cousin - see above - just sent me email with the following closing sentence:

I don't like it either, but apparently there is no rule against it. OTOH, it is easy to ignore.

"Yug" is a measure of time, 4,320,000 years (12,000 divine years). "Sahastra" is a number, 1000. "Jojan" is a measure of distance, from 4 to 10 miles. Multiplying them does not make a distance, of course. Here is one of their propaganda articles: What is the meaning of line "Yug Shahstra Yojan par Bhanu" which is taken from Hanuman Chalisa? (tutorialspoint.com). Their arbitrary "calculation" goes like this:

... albeit only logarithmically.

Meanwhile in Lac Bay, Bonaire:

Because space and time rotate into each other without stretching. For c not to be invariant, they would need to rotate AND stretch.

I don't understand the new problem statement, specifically, the least value of n for a certain i, where i=1,2,3,...n.

Can you solve it for line segments instead of circles? I.e., What is the least number of smaller segments that can be fitted inside a mother segment under the following conditions: 1. The smaller segments cannot intersect or be contained inside any other segment besides the mother segment. 2. The lengths of the smaller segments must be N (N<1) times any existing segment inside the mother segment. 3. The system must contain the maximum number of segments of the same length as possible.

My 5 cents. This recent article seems to be on the topic: The Elite College Students Who Can’t Read Books - The Atlantic

You are talking about a one-way trip, right? One just flies away and gone.

Expansion of spacetime?

You meant to say rather Bose-Einstein statistics, I believe.
