Paradox? (split from Is FTL actually possible?)
Let's say some signal moves with twice the speed of light in observer A's frame. It is sent, the event S, at time ts=0 from the origin xs=0. At the time tr=1 it arrives at the distance coordinate xr=2, where a detector blows a bomb. This is event R. Observer B moves with the speed v=3/5 c along the x axis, with their x axes and origins coincide. In the B's frame, the event S occurs at ts'=0, xs'=0. The event R in his frame occurs at tr' = gamma*(tr - v*xr/c2) = 5/4 * (1 - 6/5) = -1/4 i.e., 1/4 before the event S.

If that person received the signal while moving, yes, according to this person as well.

Social science - balancing out sexual leverages between genders?
According to my research, men can basically get sex more or less when they wish, just as Also, women ask, and men choose as commonly as In general, my data support the old Russian proverb, "любовь зла, полюбишь и козла" (love is evil - makes one love even a goat; note that the noun "goat" in the proverb is masculine.)

Thy signal is received before it is sent.

Paradox? (split from Is FTL actually possible?)
In the paradox I've described, no signal is sent backward in time.

Paradox? (split from Is FTL actually possible?)
How come? Let's say events A and B are spacelike separated. Then there are observers moving with a normal, i.e., < c, speed for whom event B occurs before event A. If A is sending a signal and B is its receiving, then for these observers, the signal is received before it is sent. Isn't it a causal paradox?

Anti spam suggestion.
I've noticed that the current spam posts appear in quick successions. Is it possible to limit new members to 1 post per 10 minutes for the first day? It would take about an hour to post the 5 allowed posts.

How does human acquire conceptual concept?
Like @iNow has mentioned above, we learn concepts by being exposed to them, via experience, interactions, demonstrations, explanations, etc.

I don't know what "learn the existence of concept" means.

ChatGPT is a regurgitated Internet search. Are there any rules about a financial product advice acquired from Internet search? The same apply to ChatGPT.

How does human acquire conceptual concept?
Concepts in mind are not visual entities. When you try to visualize a concept, you get its visual representation. Concepts are different from their visual representations.

Why is no one trying to create a UFO-like engine out of superconductors that can levitate in Earth's magnetic field?
How do you get this? How come B is in N? How do you get this? What fluid?

Something weird with sight!! Check it out!
Not exactly. The light from the q is hitting all parts of the lens in your eye, but only one spot on your eye retina. Similarly, the light from the w hits all parts of the lens but only one spot on the retina. And the latter spot is not the same as the former.

The dimensions don't match. The unit of pressure is [force]/[length2], volume is [length3], g is [length]/[time2]. Multiply: [force]/[length2]x[length3]x[length]/[time2] = [force]x[length2]/[time2] which is not a force/buoyancy/upthrust. Sorry for that. Fixed.

After encountering several different circles, we neglect features that vary.

Technology Stabilization
So, you have one example of a technology that arguably stabilized, and another one of a technology that has not. This doesn't seem to justify the conclusion, Moreover, I think there are other trajectories in addition to these two.

When you draw a circle on a piece of paper with say a pencil, it also has a specific color, line width, graphite thickness, background color, electric conductivity, temperature, etc. We are capable of ignoring all these. The same way, we are capable of ignoring its size as well, and of focusing on its geometric shape.
