I'm not convinced there's a problem with shepherds watching their flocks by night in December in the Holy Land. The indigenous Awassi sheep were...

Specifically to mitigate the apparent manifest worst case scenario of the constellation being more visible and for longer than originally advertised....

Interesting about the skirt protecting the Centaur. I recently saw a video by Scott Manley in which he mentioned that Centaur stages are usually...

When I watched the launch, they showed a clip of New Glenn being built. All clean-room type conditions. The difference from SpaceX building Starship...

It sounds like a type of "singularity" (which is the idea that once humans begin to intentionally alter their own evolution, the process will...

And we should all be clear by now that MDR thinking has no difficulty accommodating Armstrong's intent here. He is merely saying that the mind of...

Maybe I misunderstand, but your future for humanity sounds like a colony of ants. Further, our cells do not knowingly act as a single body. They...

(Sorry, up to now I did not see the highlighting, Reality Check): I can agree with your last sentence, I have not analyzed this historical question....

Sorry, Shaula, I rechecked, but I don't know which part of your last post I had missed. Could you specify please? I claim that the replacement...

If these were present day requirements, then I'd expect that we'd have already a DS of our own. We haven't .. thus there must be no such present...

Indeed, it had been quiet since the end of October, where there was one day with a significant number of quakes, but it had seemed to settle back...

As Nicolas says BEO stands for Beyond Earth Orbit and we have only had 2 this year by Russia and India.

Interesting. Does the entropy of our universe correspond with 13.8 billion years?

Is the requirement for building the 'space habitats', which you say is 'part of actual reality', identical to the requirement for building DSs, or...

Technical reasons to mitigate the brightness, or avoiding a future where one cannot spot stars because a disco ball of 50k satellites is shining...

The official (industry standard) use of it is Beyond Earth Orbit. If you are below earth orbit, you are not in orbit and it's called "suborbital" or...

I found this quote from Neil Armstrong that describes the differences evident in this thread. "Science is about what is; engineering is about what...

And warm, heavy food & drinks... but January or February would have been a better fit. That's one reason why I like Wicca/Witta's halfway days,...

And keep in mind that in the rest frame of the rocket, you want a high acceleration so you're going to have a very considerable artificial gravity. ...

Science fiction? Did you mean that seriously? Because they were not proposed as a science fiction plot point but were proposed quite seriously in...

I just now did some estimates of how much background light would be obstructed by stars in our galaxy. In most of the disk the average spacing of...

If I have a moment, I will explain that my core criticism of "scientific realism" is that what scientists generally mean when they use the term is...
