Me too, I used to be interested in astronomy, thought I was going to be one as a kid, got my mind off it and became more realistic though, it still intrigues me, all that space up there, im pretty sure it always will. Unless we find a hidden cache of alien space faring technology, that we can assimilate into our own before I graduate... then it'd be cool.

1 million light years is a long walk i think....we probably wont be alive when they invent the first "faster then light" travel, its unfortinate because there would be all sorts of intresting funk out there i reckon :P. Well mabye i should donate my body to be cryogenically frozen? to bad the only ice i can afford is the type that goes in an eski :P

Interesting topic and im glad you brought it up. First of all... the new planet which can suposidly support life is not 1 million light years away as i have reason to believe its located in our own galaxy... or possibly the neighboring galaxy. It is approximately 245,000 light years away or is it 245... i cannot remember. Anyway... i dont really see what all the fuss is about anyway, considering that even the moon has potential to sustain life we really dont have to look that far. Russia and the US have both set a date of 2020 to launch the first moon mining colonies. If your intrigued or have no idea what im on about, look it up because it truly is fascinating. Ill give you a clue... its about fusion technology which is being built as we speak.
Our galaxy is 100,000 light years in diameter. Note that light travels 300,000,000 miles every hour. Now times that by 24 to get 1 day, then times it again by 360 to get a year. Now thats 1 light year in miles.
From our knowledge of physics it is impossible to travel faster then light. But then again... nothing is impossible. Note that once crossing the light barrier you will be effectively passing through time. And the faster you beat light... the more you will see in to time... if that makes any sense :)

The new planet borders a red dwarf star. Its far different from the moon, the moon is desolate, this new planet is like california with a lot more gravity.

the really creepy thing is, that even though the Hubble telescope has seen those really distant galaxies etc, that there are most likely even more beyond those.. even in 100, 1000, 10000 years i don't think the universe will ever be able to be mapped.

Yeah Ark its 245 million light years. Also, I was just studying about the new technology of fusion. Oh and I think the moon would be a bad place, consider the dark side of it unless we can make it MUCH warmer and have light!

i really doubt we can live on the moon.. i mean we can but we need a whole lot of water and oxygen shipped there every day (which will not be cheap!) unless u want to try to throw soil all over the place and make it rain over there or sumthin and if u can sustain all heat from the sun.
o and not to mention the layers that we need like we have here on earth like the stratosphere and what not
What I found out about the universe a few months ago was pretty cool. I never knew this, but our Universe is always expanding (spreading apart). Slowly our galaxy is becoming more and more distant from other galaxies. We know this because of the doppler affect. If you look at planets or moons with a telescope from Earth they have a red-shift. This is caused by the Doppler Effect, meaning they are moving away from us. If they were moving towards us they would have a blue shift.
If you don't believe me just google it or go here:

Yeah cush I knew about that for a while. There are 3 possible outcomes of our univers.
1. Just keeps expanding, never stops
2. Just stops expanding and stays like that
3. The crunch (Reverse of the big bang, then another big bang)

Since light travels at a set speed, the images we are receiving from the telescope is that of X years ago. So it makes one wonder, what does it look like as of now as apposed to what we see from the light.

Well..that planet we saw could be harboring life in the present..that's what it could mean..because the image we receive right now is more than 245 million years old. In theory of course..

What planet are you all talking about? The one that I've heard about on the news recently is called GL-581c (stands for Glisa I believe). It is only about 20.5 light years away. When I say only I mean like about 120 trillion miles, so yeah it is quite a walk. Isn't this the planet you mean? If there has been a new one I haven't heard about it.

Its a fact we can live on the moon. I have been doing a project on the moons known properties. "Moon Dust" as you may call it, or may be familiar with the term isnt what it seems at all... and before i continue, you made a very good point about having to ship thousands of tones of O2 and H2O. But now i shall continue... the moon dust has an extraordinary level of Oxides and Hyrdogen, in actual fact. A professor studying this moon dust found that at 80 degrees Celsius, the dust evaporates, and the oxides and hydrogen atoms fuse to become water. Because of this incredible discovery... it deletes the fact of having to ship a constant supply of water and oxygen to the moon to sustain life.
With water... it is possible to create a livable atmosphere... perhaps in a large dome of some kind. Terraforming the planet is out of the question at this time due to the lack of gravity and an electromagnetic field (a vital need to keep an atmosphere stable)
The moon rock consists of one other very important material. Helium2... this is the source we shall be using for nuclear fusion. The moon is full of it and is worth billions per tone.
Soldier of war has a more practical answer to the livable planet.... 20.5 light years is a much better answer, this is because 245 million light years is approximately 20 large galaxies away. There are only 3 or so galaxies which can be viewed in great detail (i.e , view separate planets), that is our own... and our two close neighbors. Some satellite telescopes may be able to view many galaxies... but cannot view separate solar systems within them. It would also not be very practical to try and observe that far out. The people that found the planet are searching for suitable planets... but searching that far out wouldnt be any good to anyone. Even if warp technology was discovered... which would be very similar to travel in say... star wars... it would take many years to travel to a different galaxy. And as 275 million light years is about 20 galaxies away, it would take many thousands of years even with that kind of technology. Keeping to your own galaxy which consists of many billions of stars (approx 200-1000 billion) would be the wisest thing to do, before trying to venture further.

275 million lights years = 275 million years traveling at the speed of light.

05-06-2007, 10:16 AM
yep thats right no shelter. But that also can be translated into 275 million years at which an electromagnetic wave has been traveling. For a light wave to travel that distance without being dirupted is quite a marvel, and to magnify it to be able to view a planet is also a marvel... in actual fact, i dont think thats possible yet. At that distance, the only thing a telescope (even hubble) can see is just a white speck of a galaxy 275 million light years away. A telescope is no different to an eye, it just has greater magnification potential... but theres always a limit. Unless you dont actually use the visible spectrum... but even then... theres still a boundry

Yeah but what the hubble was viewing was the light from those galaxies and what ever but 275 million light years ago. It is definatly not seeing it as from present.
Also, I do find it easy to believe that the light wave can travel that distance without being disrupted because most of our universe is empty space! The image would therefore be disorted in some way not twisted into shapes from the cosmic background radiation (which I so doubt) and if they did so hit planets stars, well they would asbord that light! Our universe right now is expanding because of the more red shifts we see so more empty space and more space for that light to travel.

05-08-2007, 10:06 PM
Think of it this way shelter... Light takes time to travel... so even something in front of you will be seen in the past.... but the time past before you see the image isn't really noticeable... You must remember that time is merely a rule we have made in order to understand the principle of light... time is basically a measurement. Therefore, time can be manipulated. Warping light effectively warps time but such methods haven't been put into practice. Obviously we cannot see into the future, as the future does not exist (but thats only following the rules of physics). However, viewing the past is a definite possibility, and the only thing which is required in order to view the past is way to travel faster then light... or manipulating light itself to travel slower. Must go... will try and explain further a lil bit later... need to say a few thing about dark matter.

Well the Universe is huge, and there is NO DOUBT that there are other life forms out there.
But who knows, maybe some life forms evolve faster thus making them smarter, and some evolve slower making them use shit for a weapon during war. There could probably be a Galactic War or some shit by other races with high tech flying things and probably destroy PLANETS.

Besides the fact that we are only just now seeing the light that was reflected 245 million years ago.
That's almost the entire amount of time from the mid-triassic period to now. Easier way of putting that: Start of dinosaurs to extinction (180 million years) Extinction to today (~65 million years)
So the life there, if there is any, might be super-evolved now, or could have died out millions of years ago. Who knows?
Maybe through a complex system of reflections, we are seeing our own planet as it was, more than 500 million years ago.

Basically, what we see out there, is what is out there but 245 million years before what it currently is. Advanced life could have come and gone between what we see and whats there.

No, that's only true for that planet. As planets vary in distance, so does the amount of time required for light to reach us.
