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.

Back in the USSR, there were "academic institutions" whose purpose of existence was interpreting old texts and records in a way that proves that everything has been first invented by Russians. They did a good job. People used to say, jokingly, "Russia, the birthplace of elephants..."

That what I've learned from the CalTech course, The Solar System Science. That was about 7 years ago. Also, e.g., in Pluto - Wikipedia: And, e.g., in Kuiper Belt Objects: Facts about the Kuiper Belt & KBOs | Space:

There are other bodies in the Kuiper belt of size and density similar to Pluto. They are as 'planets' as is Pluto.

Maybe they count riverbanks, too (?)

Like any other religion I know, you translate and interpret ancient texts any way you like. BTW, by today's definition of planet in astronomy, there are 8 planets in the Solar system, not 9. And if you count Pluto as a planet, then there are more than 9.

Exactly. Also here: 9 Spheres of Heaven (Dante's Paradiso) - History Lists

Hadi Kharaghani's Homepage (uleth.ca): "At the twilight, a moon appeared in the sky; Then it landed on earth to look at me. Like a hawk stealing a bird at the time of prey; That moon stole me and rushed back into the sky. I looked at myself, I did not see me anymore; For in that moon, my body turned as fine as soul. The nine spheres disappeared in that moon; The ship of my existence drowned in that sea." Rumi's Divan Shams Tabrizi, 649:1-3,5

Where does it say so? I don't know of such a limit. As the answers above indicate, it took a very long time and many different ways. Here is one scheme:

What benefits would it have compared to sending robots?
