The clock moves .866 m in the time the light moves 1.323 m. Thus the clock speed is v=.866/1.323=.655c. The time dilation for this speed, gamma=1.323. The time of the full trip of light is (1 m)/c in the clock's reference frame, and (1.323 m)/c in the external observer reference frame. I don't see any conundrum. This is what time dilation is.

This is incorrect. In the time the clock moved .866 m the light covered not 1 m but sqrt(1+.8662)=1.323 m, i.e., 1 m vertically and .866 m horizontally.

How do you get v=.866c? Is it a given?

For me, it would be very sad. Plus, some of the goals are such that failure to achieve them might be quite painful. E.g., one of my early goals was escape from the USSR. A failure in this one meant more than just not escaping. It meant trading my warm city of Baku for much colder places.

I believe they are, although I failed to achieve some of them. E.g., my first marriage.

I measure my success against my goals.

It is so, indeed. I've watched this from within, as lived in the USSR then. The propaganda there magnified all and every failure they could find about USA, big or small. They had nothing bad to say about the Moon landing.

It does not. There is time dilation at work in this experiment, not a length contraction. PS. If there is something confusing in the equations, ask for a clarification.

No, of course not. I suggest that people came to Australia in an earlier migration event. I don't know any more details about that map. I used it to demonstrate to the OPer that the spread was long and not continuous.

In the clock's reference frame, the proper time for the light to cover distance l is l/c. In the external reference frame where clock is moving with velocity v, the light covers the distance sqrt(l^2+t^2*v^2) in the time t: t^2*c^2 = sqrt(l^2+t^2*v^2) From this equation, t=l/c*gamma, where gamma=1/sqrt(1-v^2/c^2). Thus, t is the proper time times gamma. No length contraction here.

Yes, I do not like or accept as a valid pov this assumption. I don't see any justification for such restriction.

I could point with two fingers to a point on the intersection of the two directions.

So, if I point to a point and observe that nothing happens there, that point does not exist?

No problem. Ignore my question. Thank you.

Isn't Shannon entropy of one state 0 regardless of what kind of state it is, homogenous or not?

Maybe because Australia had people already. As I remember, the Polynesians and Australians were trading in Australia's NE.

I don't remember the details, and I don't have any preference regarding the hypothesis, but I seem to remember that the people in SE Asia now came there after the previous people living there spread to Polynesia.

There were no ledges.

I don't know about Maoris.

No, it does not. The time dilation and length contraction you mention apply to two inertial frames moving relative to each other. This is not the case in the expanding universe.

As long as quantum gravity is not involved, yes, they are. Yes, GR predicted that the universe is not stable, i.e., either expands or contracts. But what do you mean by

It doesn't matter how they are classified. The point that pertains to this thread is that the number of 'planets' known today is not 9.

I guess somebody needs to say this: Life does not have a purpose.

I'd like to understand this better. For example: How much information is there in the number pi?

AFAIK, this hypothesis has been refuted long time ago. Current understanding is that they came from SE Asia.
