New study sheds light on origins of life on Earth
I have a question about the RNA world (the idea of which is quite attractive to me). Do we consider "first living entities" or the entire world was one living entity, without membranes? Added: Or, each separate "pond" was a living entity?

Creation and Destruction of Imaginary Particles in A vacuum and Relation to Size of Universe
How it is if we restrict the question to one regime, after inflation and before the expansion accelerated again, i.e. say between 3 s and 7 billion years or so after BB, when the expansion was decelerating due to the matter and radiation content? I think the OP meant virtual rather than imaginary particles. My answer to the OP questions stays. No.

Yep, this is my question, too.

TRIZ
Very interesting! No, unfortunately I don't read Spanish. And (not so unfortunately) I am not interested in philosophy. However, if I may ask, when / where / how did you study TRIZ? The description of your book says among other things (translated to English by Google), "In it there is a broad panorama of Altshuller's work, its content and its intentions". I happened to have an intimated knowledge of these, because I've learned TRIZ directly from Altshuller in 1970-72, and was directly involved in TRIZ development and teaching in the Altshuller's lab, part time, in 1972-79. In addition, I knew Altshuller personally even before all that, because he was a colleague and a friend of my father.

Cosmological event horizon.

Creation and Destruction of Imaginary Particles in A vacuum and Relation to Size of Universe
On a smaller scale, perhaps it would. But if this finite size of the universe is greater then the size of event horizon, I don't know how expansion behind event horizon affects the energy levels here. Do you?

Creation and Destruction of Imaginary Particles in A vacuum and Relation to Size of Universe
Let me try. As the universe expands it gets more vacuum. But it is the same vacuum, the vacuum does not dilute. Thus, the answer to the questions is, No.

Mutation (split from The Selfish Gene Theory)
I wondered (just a little bit) what has happened to the "modern genius" Dembski. Did he mutate?

Cosmological redshift, another thought experiment
To show in the sense of to demonstrate, not in the sense of to prove.

Examples of Awesome, Unexpected Beauty in Nature
No, they are not venomous. "The spotted cleaner shrimp (Periclimenes yucatanicus), is a kind of cleaner shrimp common to the Caribbean Sea. These shrimp live among the tentacles of several species of sea anemones. They sway their body and wave their antennae in order to attract fish from which they eat dead tissue, algae and parasites."

I can't decide. What do you think?

Cosmological redshift, another thought experiment
Certainly not.

Examples of Awesome, Unexpected Beauty in Nature
Same kind of shrimp as 3 posts above. Different anemone. Or rather the same kind of anemone populated by a different algae (?)

Dark matter
Is this question referring to some other theory of gravity, different from GR?

Cosmological redshift, another thought experiment
This thought experiment attempts to show how cosmological redshift is NOT a Doppler effect. Let's imagine that the universe expansion, for some dynamic reasons such as strange behavior of dark energy etc., is highly non-uniform, i.e. it stops and goes. Just for the purposes of this thought experiment. At the time when the universe is not expanding, some far away galaxy emits light. While the light is in transit, the universe expands for some time and then stops again. At the time we observe the light, the universe is not expanding. The source and the receiver do not move relative to each other at the time of emission nor at the time of reception. Thus, there is no Doppler effect. Will we observe the light redshifted? (My answer: Yes.)

Mutation (split from The Selfish Gene Theory)
"An obsession is an unbidden, intrusive thought, image, or urge that intrudes into consciousness; attempts to dispel it are difficult and typically lead to anxiety. These thoughts, images, or urges are recognized as part of one’s own mental life." (Obsessions | Johns Hopkins Psychiatry Guide (hopkinsguides.com))

Metric for similarity/difference between languages, a suggestion
Me neither. This is so. But, the situation could be simply like this. Consider some people who live on an island with unique flora and fauna, from which they obtain their food and materials. They have to have a language to talk about these flora and fauna. No other language has anything like that, because no other people ever interacted with this kind of flora and fauna. It seems to me that in such case, this, although large but idiosyncratic part of their language has nothing to add to our understanding of how their language compares or relates to other languages. It even could work the other way around, i.e. understanding of other, more generic parts of their language could help to understand how this idiosyncratic part works.

Blocking a thread ?
It's a trade off.

Thank you. Rolling up my sleeves

Is there a way to block a specific thread that I'm not interested in but it crams my All Activity page?

TRIZ
What a bunch of baloney. Reminded me of my argument with a chemistry teacher back in high school. She was "showing" us, as was required by the official propaganda, that the periodic table of elements is an evidence for the "law of transformation of quantity into quality", one of the "laws" of dialectical materialism. That argument got me in a big trouble, escalated to the school principal ...
