Artificial light could be used instead of sunlight. Much of the basis for this answer comes from this article. The article is mostly about sleep cycles, but it includes some pertinent information. ...
Physical health Sunlight is popularly regarded as beneficial due to the production of vitamin D, but also popularly regarded as non essential since vitamin D can also be gained from diet or supple...
According to this answer to another question an Alcubierre drive would need to have a channel setup far in advance. So with such a technology, you'd need to have a network on established lanes just...
The main problem actually is where do you put the rock that you dig out. You would either need access to the surface to dump it somewhere or some way to compress it and then use the compressed rock...
An Argument for Space Shipping Lanes We tend to think of space as very, very large and very, very empty. This isn't necessarily the case, as we see with Space Junk, the Oort Cloud, and other thing...
Hello everyone, I am thinking yet again about infrastructure. (my calendar project recently asked about... well, that's outside my expertise, I'll get back to that eventually) And I am thinking of...
I've been researching the idea of spreading out vast sheets of aerogel across regions of Mars. This would theoretically have the effect of both warming whatever land is under the sheet - thus melti...
I don't think it's unreasonable for shipping lanes to be established. There's a few reasons why shipping lanes become established on Earth: Currents As you've mentioned, the currents play a larg...
While space is vast and infinite, mankind isn't. Travel 'lanes' through space may include known protected areas that are safe to travel in and free of navigational hazards. Established lanes and ...
Actually, and as also pointed out, auroras are sometimes seen in temperate latitudes on Earth, so are not restricted to high latitudes only (although they tend to be more common there). Taking Wik...
Planets which have something that we might consider to all be a single climate given the way we classify things based on earth is entirely plausible, for certain climates at least. Mars easily qua...
This depends heavily on how ships travel faster than light in your universe. Take Babylon 5: space travel is controlled by gates which allow you to enter and exit hyperspace. In this situation, s...
You could eliminate the magnetosphere entirely which would let the solar wind hit the atmosphere directly. Of course this would be on the day side, not the night side. To get it to hit the night s...
I am wondering if habitable planets could form around stars in super dense dwarf galaxies. There are some super dense galaxies such as M60-UCD1 and M85-HCC1 which can have a typical distance betwee...
So, my understanding of how Alcubierre drives would theoretically work is not particularly complete. I know it involves compressing and expanding space, but I don't really have an intuitive grasp ...
Suppose, for instance, you lived in a world filled with nasty monsters and other creatures of the night, all of whom wanted to kill you and eat you in various ways. Now, the good news here is that ...
Roughly how long could an 'Oumuamua type object get if created naturally or if created artificially using fused rock? What would be the limiting factor governing the length of such objects? Oumaum...
There are tables, created for mining engineers that list types of stone e.g. sandstone, granite, limestone etc and tell exactly how large a tunnel they will support, how big galleries and where to ...
Energy Storage: Nanocapacitors A Capacitor is two layers of conductive material separated by a layer of insulator. They contain no moving parts, have no chemical reactions, and charge extremely q...
Assumptions: A typical human has a mass around 70 kg. They consume about 1.1 W/kg continuously(I'm approximating) throughout the day or about 96 kJ/kg daily. This together with the average mass giv...
Turning my comment into an answer. 200 years is an incredible amount of time given our current rate of discoveries...so it's hard to tell what options we might have...though I would suggest our cu...
One of the promising forms of energy production that I know of, which isn't yet well developed enough but could take off and is scientifically sound, is focus fusion, as applied with a dense plasma...
If we assumed massive increases in computer power efficiency in the future, the Fujitsu K (http://www.fujitsu.com/global/about/businesspolicy/tech/k/qa/index.html#qa12), which is good for a bunch o...
This is a complicated answer since every piece of technology you mention is going to be improving over those 200 years. That said I think the answer will actually be a blend of several renewable re...
The power requirements are going to be highly variable. Just think about today's electronics -- you could put a set of AA batteries into your TV remote and have it work for years, but an identical ...
