@catsteevens flying at that speed inside an atmosphere will break the atoms that make up the air. In other words: impromptu atom bomb.

@Nosajimiki for two travelers synching, yes. For 3 or more, no, because simultaneity is an illusion. Once again, for multiple denizens in the galaxy, the same events have different timestamps (even compensating for relativity) and different orders. 2024.1371 works for everyone and everything at your stellar system. But ask two different historians far from each other what happened when it was 2024.1371, and they will give you two mutually incompatible histories.

@Nosajimiki what I jave been trying to say is that 2024.1370 is local and valid to you. It's not valid to anyone else moving at a fraction of c relative to you. It is your 2024.1370, not the galactic 2024.1370. If you wish to impose your own local time as the galactic one, people in other star systems will be able to use it to sync with you, but not among themselves.

@Nosajimiki this is what I have been trying to explain - if I am not im the same frame as you, I can (and depending on speed and position, probably will) see these things happening in different orders and timestamps. Jesus was born after the Nova for you, but before the nova for me from the other side side of the galaxy. Also even if we were equidistant to the supernova, we could count different timestamps for it just because we are at different speeds, even if we adjust for time dilation.

Feb 16, 2024 22:34
@Nosajimiki indeed but people would still disagree about sequences and timestamps. You tell me that dinosaurs were extinct when a certain supernova happened... I say that the supernova happened before dinosaurs went extinct. And we're both right. So if you want these ordered in a history book, you need one edition for each frame, or you need a priviledged frame that overrides history for the others.

@Idran it does, but our universe does not behave like that.
Oralista de Sistemas
Feb 16, 2024 22:34
@Nosajimiki you correct that for your frame, and you can calculate the correction for other frames, but the fact remains that things will happen at different orders and timestamps for other frames.
Oralista de Sistemas
Feb 16, 2024 22:34
@idran no, because all other frames that are moving fast enough relative to it disagree on the sequence of events. So any historical information tracking becomes useless for all but this priviledged frame.

@MichaelK even if they used a single pulsar as a clock, the problem of simultaneity remains. Alice may calculate her age as X rotations of the pulsar, and know that she was born before the release of Half-Life 3, and that's true for her. Bob will calculate Alice's age as Y rotations instead, and know that she was born after the release of Half-Life 3, and that's true for him. They only agree that things happened, but never when nor in which order, even if they adjust for each other's time dilation.

Food for thought: at the Moon's altitude, escape velocity from Earth is around 1.44 km/s. So the ejecta that misses the Earth will orbit the sun, but at orbits very close to Earth's. Secondary bombardments will happen over the ages, and each one will have rocks coming in with at least 11 km/s on impact against the Earth.
Oralista de Sistemas
Sep 25, 2023 04:45
This. This is a perfect answer. For the record a trillion tons (0.001x the calculated ejecta mass here) is the lower estimate for the mass of Chicxulub, the dino killing asteroid. The upper estimate is around 460 trillion. So if 0.01% of the Moon ejecta hits the Earth, that's still the mass of 0.1 to 1 Chicxulub's. Those ejecta will be coming at a slower speed also (5 km/s instead of the 11+ km/s of Chicxulub). So we do have something that would cause a lot of damage, but very much survivable.

@JackAidley I agree, plants are more efficient. Fungi would require a lot of engineering to become even feasible, but then again OP was not clear about tech involved and UV is better absorbed by melanin than most plant pigments.

@SamKitsune Check this out: en.wikipedia.org/wiki/Radiotrophic_fungus scientists in real life are proposing the use of such fungi as shielding against space radiation as well.
Oralista de Sistemas
Feb 15, 2023 17:50
@JackAidley some fungi have evolved to do radiosynthesis, which is similar to photosynthesis but they extract energy from gamma radiation. The pigment they use is melanin, so they could hypothetically use UV radiation as well.

"Demon core" has a conotation in physics, it's a fissile core which was used in the development of nukes. If your world has modern technology, you might wish to rethink the name (or not - only eggheads and some rare nerds know the term, so you could also resignify it).

@nanoman good question. I had considered that figure for head plus neck, but now I can't find anything about estimates for head and neck separately. You're totally right when you say that should those 10% be just the head without the neck, then the human part of a centaur should be even lighter compared to what it is replacing.

@Pureferret about the Rock and weight estimates - I am assuming a standard, male race horse of the Thoroughbred breed here. The Rock would be too large to graft onto that horse. A regular average Joe on the other hand would be a perfect fit.

@jamesqf that would only make sense if the US was the sole, or at least main developer of drugs in the world. They aren't. Drugs and treatments are developed everywhere without such exorbitant prices to the end user. In my own hellhole of a backwater native country there is active research on new drugs and treatment for Alzheimer and scientists made temporary artificial human skin from fish skin that saves people with 3rd degree burns. Such things are made either free or cheap to people via our equivalent of NHS.

So the actual cause of destruction is natural decay in the short term + lack of maintenance (i.e.: no one to switch the old drives with new ones). This is actually good for the story I'm writing - I want people to become disconnected with the past - but man, that would be a bummer if the apocalypse did happen in real life.

@KeizerHarm populations from the south of the Sahara have practically zero neanderthal genes, while the rest of the world generally has a handful of neanderthal genes. Some of those genes play a role in inflammation, granting more resistance to some diseases but LESS resistance to others (that is the case of COVID-19). You can't just compare death rates at different places without taking into account this, and a lot of other factors. Besides genetics, how isolated populations are, and their response to epidemics are also factors.
