Space isn't. No ones going to hear you scream but pressure waves do propagate in the thin stuff that makes up what we puny humans call the vacuum of space.
So what is the speed of sound in space. It varies depending upon the density of space but is approx 10-100 Km per second. The exhaust gasses coming out of a liquid fueled rocket nozzle have a speed of about 4.5 Km per second. So, not supersonic with reference to moons (lack of) atmosphere.
History shows us the solution. Most stay put, farm and attempt to defend their wealth. Others travel around and steel the wealth from those who stay put. There are also the fringe bands that travel to stay close to moving resources such as migrating animals. In time those that raided tend to join in with the subset of the stay-putters that defended the farms and offer to 'protect' the farming communities from their neighbors. Thus are kings and nations born. The nomads never get a look in. Best not to have an apocalypse as none of it sounds fun.
If there was a load of anti-mater in the universe we would certainly be able to 'see' as it interacts with normal mater quiet well. Dark mater on the other hand, if is actually exists, keeps itself to itself as far as interacting with the stuff we can see. Oh, and by the way, we can 'see' quiet a long way, almost back to when the first stars were forming.
p.s. As for an equal amount of mater and anti-mater at the beginning, still just a theory. There is some wiggle room with the CERN experiment which might yet show that anti-mater behaves differently than mater in some crucial way which might account for it's lack of existence in the universe we observe. Perhaps it might go some way to explain why less anti-mater than matter formed during the big bang leaving the mater we can see. Or, perhaps we are just wrong about the big bang and all that.
The coal fired power station site near me (Ratcliffe on Soar) would be ideal as a development site for SMR's being just a few mile south of the Rolls Royce factory but it is more radioactive than would be allowed for a nuclear facility. Apparently it's ok as a 'normal' power station...
There really needs to be a way of indicating irony or sarcasm in posts. Which I guess is a good lesson in itself of why you should be careful about the meaning or intent you attribute to anything you read or otherwise consume. Be you an LLM or a human.
Facts, bullshit, truth and lies are labels we put on things that do or do not fit with our current world view. A world view we each build individually and collectively. We perform many many little experiments modeling cause and effect, stimulus and response and other such simple things. We do this both internally, in our heads as is where, as well as out there in the real physical world. We remember the results and use the resulting web of data, a model of the world, to navigate our way through life.
I don't see that as too far different from what the LLM models are trying to do, all be it in a limited and one dimensional way. How much of a world model or theory of the world does a newly conceived human have? However much it is, we all end up with a much richer model as we grow older and we must do that somehow.
says, "Meta has already committed to what Datatilsynet is asking for (consent), but it cannot simply flick a switch to comply, the company said".
But it could flick a switch and not offer it's products in jurisdictions in which they do not comply with the local laws as is the case with companies producing physical products.
We had to scribble coding sheets with incantations and send them off to the high priestesses of the Hollerith. After the next full moon, if you had been a good boy, in the great tray of doom, a small banded package of cards, bearing your name and containing their great wisdom encoded via holes and not holes, would await you. Full of hope and trepidation, you would transfer the holy package to the tray of feeding awaiting the uncaring attention of the operators of the great engine. If you were lucky, your feeble set of cards of wisdom would be scooped up and join the many others awaiting attention of the primary carcass in the hall of wind and noise. Once fully digested and considered for less than a blink of it's invisible eye, a great tearing noise would erupt from the chained scribes. Devouring banded sheets of bi-folded parchment at an infeasible rate, they would transcribe the great engines calculations, dumping the results in the bin of outputting. Some time later, if the correct muse entered them, a kindly operator might dip their holy hands into the bin and harvest the great engines uncaring doodles. With aplomb, they would separate each judgment, write the name of the troublesome acolyte in righteous script atop the engines conclusion and place them, without a care, into the pidgin holes of lost hope. Full of trepidation, you would retrieve your response. Unfolding the worryingly short deliberation, you would scan for the engines wisdom and there it was:

Hum, perhaps making sure idiots can't fuck things up too much is a better ambition for computer software design; especially for operating systems, databases and programming languages. It was certainly the approach taken by developers of mainframe operating systems and many databases and languages developed in the seventies and eighties. We, of course, do things better now.
Perhaps you could just decide for yourself what you might like to watch. There is a difficulty in knowing what is available but this is true of all big data repositories and is usually solved in some way by knowing what it is your interested in or just browsing. Kinda like libraries or book shops, although you do have to walk past the algorithmically chosen books on display at the front of the shop.
As for inappropriate pimple related suggestions; could I interest you in:
