You would need some system for recapturing and recycling the water to grow those plants though, i'm sure this would be as simple as keeping the plants inside a plastic tent to condense any evaporated water?

My understanding is that the light is not bent at all, but the gravity from the singularity bends spacetime - the medium which light travels through instead -Thus changing the velocity of the photons as they must follow the curvature of spacetime.

Don't be silly, the earth is flat. If you walk to the edge of it you can throw your evil coke bottle over the side.

What are the chances of there being life on Titan? All be it evolved to survive in a differently mixed atmosphere.

You guys make it sound so simple. OK I admit that i'm certainly no expert on this but isn't the reason we have very little knowledge of the deep ocean due to the fact we have only a handful of submarines that can withstand the pressure?

Even if we were to build in shallower waters, a structure large enough to function as a permanent residence would still need to be able to withstand an incredible amount of pressure; How do we just "drop" something like that from the ocean surface and wouldn't it need to be anchored?

In space the pressure problem is reversed as atmosphere inside the structure is only pushing on a small surface area to get out (rather than being sucked out) and I imagine isn't as much of a problem to get around as having a 1000 or so atmospheres crushing down on a large surface area.

I know there is technology to somehow extract oxygen from surrounding water (not sure if it uses electrolysis or not, I don't think so but the name of the technology evades me right now) and would be suited to providing an underwater outpost with oxygen, but aren't there such things as Co2 scrubbers already in the ISS and space shuttle?

Building and maintaining a permanently manned base on the moon, or the same for a permanently manned base on the ocean floor?

What would be the benefits of having either?

I guess it was too many cats :-\

"Small" is insufficient. It must be identically zero.

I suppose this statement inherently means that photons have no mass?

If so, then what are they?

I'd heard light being refered to as a wave, which would be fine for the statement above but also as a particle which is the bit that confuses me...

How can it be a particle if there is no mass to it? The word particle implies there is something there and zero mass implies that there shouldn't be.

It looks more like a bluey green to me.

I don't like the fact that within a few generations it isn't going to be big enough for us unless we start making places like the sahara habitable.

The problem with that, i'm assuming is the fact that current fusion technology can at best make breakeven and so either takes just as much energy to create those elements or more energy than we get out.

It is not sustainable for anything more than a minute or so.

I disapprove of the lack of LongCat.

Why do Red Giants output more energy than a main sequence star when the reason they have become red giants in the first place is because their nuclear fuel is running low?

If you go outside on a perfectly clear night and as long as there is no light pollution at all you should be able to see one of the spiral arms of the Milky Way very clearly.

Truly a sight to behold.

Perhaps you might think of using Guar gum? It's a thickening agent/emulsifier used in oil drilling to prevent fluid loss among other industrial applications.

I'm not entirely sure how this would bind with ethanol but may be something worth looking at.

Well, given that I joined in July 2009 and have made only 46 posts, going by that average that would mean I would have access to the Philosophy forums next year if I don't start randomly posting spam to get my post count up.

Being locked out of the Philosophy, Religion and Ethics forums by default.

Do I have to prove something first or have a certain amount of posts? I'm not exactly new with 40-something posts but neither would I say i'm well established.

I don't necessarily want to post in these forums all the time but occassionaly there's something I feel I want to comment on.

 

Another idea I had was if we could combine two of those, have them link up, and then have them create a vacuum to make the object pass through the tunnel almost as fast as light.

Why would we need it to create a vacuum if it is space based - or am I missing something?

I guess my top 5 of all time would be, though not necessarily in any order:

Dune - Frank Herbert

Starship Troopers - Robert A. Heinlen

The Neon Genesis Evangelion series of manga - Hideki Anno

(Being a highly introverted individual this book spoke to me on a level no other media ever has)

The Zombie Survival guide - Max Brooks

(Gotta be prepared for the impending zompocalypse - Are you?!)

Homers Oddyssey - Well.. By Homer I guess

Hi,

I'm Sven - I wouldn't say i'm new here but i've not posted in this thread yet.

I'm from the UK, not studying anything but do have an interest in the way the world works.

I guess that includes Physcial Sciences, Astronomy & Cosmology, Theoretical Physics and Geology - Anything that explains how the world around me works is favourable to blind faith.

How much like Fallout 3 is that game?

Isn't the standard game to test your machines graphics capability at the moment going to be Crysis?

#2) is this advanced tech gonna be expensive or considering we've been given the schematics to acheive it mean that we can produce them for the price of a family car?

I recently tried to play Starcraft II through less that legitimate means. Unfortunately I couldn't get the graphics rendering working correctly.

Any idea when this is to be oficially released? Blizzard have been hush on the subject for some time.

I asked a similar question here:

Maybe I shouldn't have put it in general discussion and it would have gotten more views.

I bought an Xbox 360 over the weekend. I've been playing Final Fantasy 13 which is ok, I tend not to enjoy those sort of RPGs (compared to the likes of Fallout 3).

I'm importing Mushihime-Sama Futari 1.5 and E.S.P Galuda 2 from Japan which are 2D bullet hell shooters. Can't wait.
