Life elsewhere is likely. But visits? No

[metal_geek]

There's a pretty neat thought that as stars progress through their life cycle, creating elements, and finally exploding, that all the elements contained on our earth has been "processed" in one or even several stars at some point in the past. That means that we are all made up of basic elements created in stars of the past. Then eventually when our star consumes us or whatever our end planets end is, that whatever basic elements are here.. including the ones that make up our bodies will be redistributed through some other corner of the universe.

It's possible that this very second you could contain elements that were in some alien race billions of years ago.. That, or that billions of years from now, you could be part of some other Plantet, asteroid, star, even being.

It's one thing to take Distance into account when you think about other life.. but take into account time, and the chances we are alone, become even more... astronimical....

It's funny that even the skeptics who use the numbers and come out with conclusions that the odds of life delveloping in a galexy is less then 1... can't say that they life doesn't exist.

Do you have an album of pics on the net? Or you just keep most of your photos on your computer? Love to see others if you've got them uploaded.

Of course they can't, you can't say it doesn't exist. That doesn't mean it does though.

And I can say there isn't any conculsive evidence yet.

Astronomers have captured enough light from two planets far beyond our own solar system to reveal details of their chemical make-up, marking a new phase in the search for extraterrestrial life.

The research builds on earlier work with the Hubble Space Telescope which detected sodium, hydrogen and carbon from starlight passing through the atmosphere of the planet with polycyclic aromatic hydrocarbons and shows that it is possible to measure the chemical make-up of "extrasolar" planets - those outside our solar system - and to hunt for the chemical markers of life in the far-flung reaches of space.

Thanks for the nice comment about the picture by the way.. I don't really have anymore online, aside from a couple on facebook. Honestly I haven't been doing it for very long, maybe a year or so.. mostly Moon, some constelations, some milkyway, saturn, jupter kinda stuff... I'm a complete noob compared to most of the people who take space pictures so I don't like to pollute the intraweb with my stuff .. ROFL... I just posted this one cause I had taken it thursday night and thought it was appropriate for the thread

I have one of the moon here at work so I uploaded that one too it's just a tiny file so the detail don't come out much but it's still pretty cool.

Here is a great place to look at space pictures.. its a monthly competition for amatures, on various targets so you get to compare alot of photos of the same object. It's neat cause for the most part anyone can take thoes pictures. That group is where I learned everything I needed to take that picture...

The Drake equation states that:

where:
N is the number of civilizations in our galaxy with which we might hope to be able to communicate; and
R* is the average rate of star formation in our galaxy
fp is the fraction of those stars that have planets
ne is the average number of planets that can potentially support life per star that has planets
fl is the fraction of the above that actually go on to develop life at some point
fi is the fraction of the above that actually go on to develop intelligent life
fc is the fraction of civilizations that develop a technology that releases detectable signs of their existence into space
L is the length of time such civilizations release detectable signals into space.

There are soooo many holes in all thoes theories.. Besides... If there is noone else out there in the universe doesn't that make you feel really lonely?... I know if I felt that lonely I'd prolly feel the need to find or invent some kinda higer power to keep me company..

EXTREME Q

[Fozzie_DeBear]

My thinking is that it is possible that we are being visited but aren't savvy enough to understand it completely.

The analogy would be that wild Gorillas or Chimps may have a rough idea about humans, but aren't savvy enough to understand the nature of the human visitors.

And perhaps that may be a little interesting to them, i'm sure they have better and more important things to attend to. Just saying that we're pretty insignificant as we stand now in the universe, so to think that they would even want to visit us is kind of arrogant IMO.

Wouldn't they at least have to drop by to determine if we were worth visiting?

[Locke]

What if aliens just spun a wheel to determine what planets to visit? Is it not reasonable to think we havent been visited simply on the basis of pure chance?

[worth]

Not necessarialy. Just point a receiver our way and they'd probably have a pretty good idea of whether or not we're worth visiting. That, and given the fact we've only colonized one planet probably gives it away pretty fast.

I'd reckon exteresterials may go by something like this:

http://en.wikipedia.org/wiki/Kardashev_scale

and since we're a Type 0 civilization, I just don't see us having any value to Aliens.

Pure chance? Sure. If I were an advanced civilization you'd want to map out the galaxy and universe like Magellan. But If I found earth, I wouldn't really want to talk to the humans. Their too stupid. Colonize a few more planets and then maybe you can hang with the big boys on the block.

It sounds like you are operating on a whole ton of assumptions. What if the aliens you are so confident exist are complete ######s? They might be stuck in some sort of perpetual stone age and play hockey with skulls and femurs or something?

Who says aliens have to be an advanced race? There might be an Edmonton Oilers Planet.

[worth]

I'm only talking about those who would have advanced to master interstellar space travel. I'm sure only a fraction of life in the universe could ever do such a ting. Most life will never get past the microbial stage. I'm certainly not saying all life will eventually evolve to this state. What I am saying is that if a race happens to master space travel, they will indeed be smart enough to determine if Earth is worth visiting or not.

Wow, that bold part just made my evening. What a perfect place for an error. I was all smiles for a few minutes after reading it.

Not being nit picky, or implying lack of intelligence, just a perfect place for an error.

And did no one like my joke? Geez, I giggled to myself for a few minutes at least while at work.
