I'm currently writing about a solar system which humans have just reached but they find that there is a colony of nanobots already 'living' on the planets. Initially from space the crew can see evidence of life but no actual lifeforms - if nanbots had landed on the planet hundreds of thousands...
In order to discuss several questions regarding my generation-ship story in parallel, without making a single thread go all over the place, this is one thread (of most likely several ones) that I'm opening in parallel. This one is less about technical questions per se, but rather about tactical...
So, I think it's possible to place an object in an orbit such that it remains perpetually in the planet's shadow, like in my awesome graphical representation. But is it?
What is this white stuff in the ants colony inside electronics?
Is it sugar? nest?
I presume the ants were attracted to the warmth of the pcb?
It's a Morley addressable smoke detector
Separate question. I saw illustrations of a smoke detector with light catcher.
But the Morley doesn't...
Centrifuges have long been viewed as the means to provide artificial gravity in the zero-g of deep space. Space colony structures like the O'Neill cylinder and the Stanford torus.
Centrifuges could also work their magic on the surfaces of low-gravity planets. Conical or paraboloidal shaped...
If alien were to establish a colony on earth, do they need human permission?
-----------------------------------------
let's say they show up on sky where not belong to any country and create artificial island on international water to set up their own colony.
even assume that they were...
Colony ship lands 20,000 Earthlings on a new world. They've been in deep sleep for six hundred years, so interaction with Earth is unlikely. What government do you think would be appropriate for a start-up colony? Presume Earthlike conditions, France or US Virginia area, no serious weather issues.
Where exactly on Mars is the best spot to set up camp for a colony? I've been reading about the Hellas Basin, which seems favorable regarding asmospheric pressure and ability to host liquid water (0 to 50 degrees F). However, it's located halfway between the Martian equator and the south pole...
Idk where i picked this up, but there is one other plausible colony destination for humans: Venus.
After a few trips on the net, I've come to the "Aerostat on Venus" side instead of a colony on mars. I'll mention some of the reasons I've picked up as to why:
1. Tons of CO2, we can use that.
2...
Thousands of years ago mankind conquered the stars... and of course it brought all of its wars along with it. One small, though highly advanced, faction was losing ground fast. Then, suddenly, it disappeared. It turns out that they decided to hide in the planetary nebula of NGC 6543, better...
Assumptions:
-more or less contemporary technology
-virgin planet which is glared by lustful humans ;)
-habitable (oxygen, reasonable temperature)
-no requirement for 100% certainty, reasonable guess is OK (the point is to find quite good place for colony very soon, not a perfect one in a few...
Hello all,
I've gotten some great help here before:
https://www.physicsforums.com/showthread.php?p=4051091#post4051091
and I come back to you again with another question.
So suppose there's a space colony, similar to Gerard O'Neill's ideas back in the 70's of ring-like tubes that...
Hi
I read an article on this about a year ago or so which outlined the issues and the possible causes. Aside from cellphone radiation, it seemed like none of the other proposed causes had been conclusively ruled out. I'm just wondering if anyone could give me a bit of an update on this...
I have read several articles about this lately. The bees apparently fly away and never come back. Is this something new or just a periodic natural occurrence? I really couldn't find anything on Google that gave an adequate answer.
I know there was a mite infestation that killed millions...
For the past couple of days, I've been fighting a painful battle with a red ant colony which has invaded my hostel room. They look like fire ants and are very aggressive. The ants seem to prefer my wardrobe and unused clothes for some reason. I've cleaned the room twice and tried to wash away...
We're on the section of logarithms, so I'm guessing this has something to do with them...
If the size of a bacteria colony doubles in 5 hours, how long will it take for the number of bacteria to triple?
I know that doubling time and all that stuff is independent of the amount of something...
The Jovian system is a superior target for self-sustaining colonization.
Quite a bunch of PF people (Nereid, all the mentors in earshot, and plenty of others) know the facts.
It is a beautiful and interesting system consisting of a variety of different moon-size objects within...
