This takes tool making back to animals that were closer to apes than to humans.

J. Gowin | 7977 comments Mystery surrounds what exactly was object US jet shot down over Alaska
https://www.theguardian.com/us-news/2...

I can't help but imagine two greys standing on the tundra. One glares at the other and says, "Don't worry we'll use the weather balloon cloak. The monkeys never shoot at balloons..."


message 353: by Ian (new)

Ian Miller | 1857 comments I imagined something similar, and were then faced with the problem of whether to shoot back.

Ian Miller | 1857 comments I wonder how they date the amphoras? Especially since they seem to be still underwater. If the dates were not that accurate, they could be even older. The Romans were very reluctant to leave the coastline, but the Carthaginians were much more adventurous and definitely sailed down Africa to get to the Southern hemisphere.

Scout (goodreadscomscout) | 8073 comments Regarding the quietest room, I'm with you, Nik. Why build such a thing? I didn't see answers to this question.

After the discussion of how to send humans into space to populate far worlds, I wonder about the assumption that clones would be programmed with human experience. Are we assuming that AI robots would have the ability to produce clones and have all the available materials to do so and to keep them alive? And to Ian's point, would DNA be viable after a long journey? How far into the future will it before we can accelerate time travel?


message 360: by Ian (new)

Ian Miller | 1857 comments The DNA will get small doses of cosmic rays, no matter the protection, and in living things these can be repaired, but in samples the destruction is additive. If the samples have to spend tens of thousands of years, they will degrade.

Noise testing. There are some applications where you need to know exactly how much noise a thing generates. For such tests one needs to eliminate both external noises and echoes.

At this point, Faster Than Light travel is entirely hypothetical. The most likely schemes involve things like negative mass and require more energy than the entire USA uses in a year. It's possible that there are work arounds, like "hyperspace". But nothing looks probable in the next couple of centuries.

If we don't develop FTL, we either have clones arrive at the colony or we send generation ships. It just takes that long to travel to the stars at sub-light velocities.


message 365: by Ian (new)

Ian Miller | 1857 comments The one way around it is to travel at almost light speed. It takes, say, 11 years to reach Epsilon Eridani, say, in terms of a person on Earth, but for the traveller, thanks to relativistic time dilation, it could be a matter of days (apart from the time taken to speed up and speed down). If he came back, his age would be trivially different, but those on earth would have aged 22 years.

This, of course, leads to the twin paradox.


message 366: by J. (new)

J. Gowin | 7977 comments Still need a huge amount of energy to do it.

Ian Miller | 1857 comments Indeed, but at least the concept does not violate Einstein's relativity.

Ian Miller | 1857 comments The Alcubierre drive has been known for a long time. However, the need for negative energy is a bit of a problem. To get antigravity in one direction and gravity in the other will take a bit of doing.

It's especially problematic given that to my knowledge nobody has isolated a graviton. This means that one of the four major sender particles essential to the Standard Model remains unproven. But that's Fringe isn't it?


message 373: by Ian (new)

Ian Miller | 1857 comments That is fringe! I am not sure the Alcubierre drive needs gravitons - besides needing negative energy/mass, it also seems to need "spacetime" to be some sort of physical medium, and we already have two very fringy things before we get to gravitons.

J. Gowin | 7977 comments I was commenting on your comment about the drive needing "To get antigravity in one direction and gravity in the other..." Assuming that we're working within the Standard Model that means gravitons. So I was having a bit of fun by pointing out that the Standard Model may have a massive hole because the graviton is an unproven sender particle.


message 375: by Ian (new)

Ian Miller | 1857 comments The Alcubierre drive comes from General Relativity, and that does not include the standard model, so i stepped back from it :-)

It is true the standard model has a problem with gravity, without a sender particle.

J. Gowin | 7977 comments Animals’ ‘sixth sense’ more widespread than previously thought
https://www.manchester.ac.uk/discover...

The study indicates that every cell in your body may be sensitive to magnetic fields. This is interesting to me because of the number of people whom I have known who claimed to only be able to sleep in certain compass orientations. Personally, I've never had difficulty sleeping in any particular compass orientation, but as a general trend I orient my bed with the headboard to the north. Locations of the rooms have varied, but I keep doing it, usually unintentionally.

There is also a question of what impact all of our artificial EMFs are having on this cellular chemistry.

Nik Krasno | 19850 comments Some say animals anticipate earthquakes too. I sleep 🛌 “heading” south in this home 🏡, in previous - it was north


message 383: by Ian (new)

Ian Miller | 1857 comments Me, I sleep head facing West (approximately). It is the shape of the room, not a compass decision :-)

To sense a magnetic field you need something that responds to it. The most common component of the body that might, in my opinion, is haemoglobin, but it has a problem - if it is carrying oxygen it is diamagnetic; if not it is paramagnetic, and that will respond more. But that would be the veinous blood and it is hard to see how that tells the brain anything. There are probably other contenders, though.

From the linked article:

Dr Alex Jones, a quantum chemist, from the National Physical Laboratory and also part of the team said: “The absorption of light by the Cryptochrome results in movement of an electron within the protein which, due to quantum physics, can generate an active form of Cryptochrome that occupies one of two states.

“The presence of a magnetic field impacts the relative populations of the two states, which in turn influences the ‘active-lifetime of this protein.”

Dr Bradlaugh said: ”One of our most striking findings, and one that is at odds with current understanding, is that cells continue to ‘sense’ magnetic fields when only a very small fragment of Cryptochrome is present.

“That shows cells can, at least in a laboratory, sense magnetic fields through other ways.”



message 385: by Ian (new)

Ian Miller | 1857 comments My thoughts on that were that migratory birds are probably as good an example of potential response as any, and their feathers would inhibit photochemistry. But maybe they have found a way around it.

Another possibility is oxygen. It is paramagnetic, and oxygen gets into the brain. I guess there is a lot of potential here for research funding applications!

I'm not that smart. Most of what I can get deep into the weeds with are things like geology, paleontology, cladistics, and amateur engineering.

Estimating apocalyptic timelines is tough. Some extinctions seem to have been grinding slogs (End Permian Extinction Event). Others appear to have been cascade failures born of a few tipping points being quickly flipped (KT Boundary). And of course none of those involved us clever, nuke wielding monkeys.

If you're asking about how long it will be until we have to leave the Earth, remember that the technologies which we would need to make a new home on another world or in the void would be as or more capable of healing the poisoned Earth.

Once life formed on Earth, it s has always remained in different forms. I do not think we can totally kill it. It is too tenacious.

I expect that for the next few centuries humanity will be expanding out into our own solar system. Luna, Mars, and Venus will be first. Beyond them are the gas giants and their moons (Jupiter has 91 known moons). And then the Asteroid Belt and Oort Cloud will be settled.
