Let's ask it differently: of all the known prokaryotic pathogens, what percent are archaea?

While there are so many detrimental bacteria, there are no detrimental archaea. Is it so? Why?

Sure. But this scenario cancels the other consideration, "No knowing where we could end up in a billion years or so."

On the other hand, if we all go extinct here on Earth, then 4 billion years of evolution will go down the drain.

Ok, thank you. I will, with the help of the paper linked by @Arthur Smith.

Thanks a lot. For many reasons, not the least of which is APD, I much prefer to read rather than to listen.

When we find a promising but sterile world, shouldn't we throw some archaea there with a purpose to spread life?

After 25 minutes he comes to the conclusion, "We don't know." Should I try the second video?

OK, (3). I don't see any commonsense issue at all. This is how probability works. When I throw a dice, there are probabilities to get anything from 1 to 6. But as soon as I get 4, all other possibilities vanish at once.

OK, ignoring (1) and moving over to (2). What does it mean to carry energy and momentum as a whole? As oppose to carrying them piece by piece?

What does it mean? I didn't see this traditional premise of quantum theory

It doesn't answer my question, nor it offers a proof or an evidence.

Or else?

To save of what? from what?

Or else?

The mechanism is accumulation of substitutions, additions, and deletions which occur during consecutive replications.

Perhaps that post referred to this, much older (IMHO, equally useless) suggestion: Hunting dark matter with DNA | Science News

The free fall acceleration doesn't depend on mass because, in old terms, "gravitational mass" equals "inertial mass". Inertial mass is "relativistic mass". Since the inertial mass changes with velocity, for the free fall acceleration not to change the gravitational mass needs to change. Weight is the gravitational mass times the acceleration. Thus, the weight needs to change.

I guess they wouldn't generally eat each other. Rather for each kind the other kind would be just like other non-living natural phenomena -- wind, rain, waves, ...

Wouldn't it be very interesting to have two independent trees of life with opposite chirality with independent evolution and ecology on one planet. Any sci-fi writers around?

Was the purpose of this post to advertise the book?

AFAIK all surviving life descended from three ancestors: Archaea, Bacteria, and Eukarya. There is evidence that both Eukarya and Bacteria split from Archaea. All is needed then is to strengthen this evidence.
