No Contact With Aliens Thus Far?

So here's my wacky theory. Of course, it's backed up with no evidence and limited scientific knowledge.

 

However, it's known that we live on the outskirts of the galaxy. Where it seems not as important as in the center of the universe. So if the center of the galaxy developed first then maybe there as more time for live to evolve. Perhaps they haven't bothered to check because it looks so...remote almost. Maybe it's hard to get here. Just like it's hard for us to travel to parts of the ocean.

More time maybe, but also much more meteor/asteroids impact and so on. So I don't know if this balances out the bigger amount of time.

 

Anyway, welcome to the forums!!!

Welcome to hypography, Monster! :)

You’re really not supposed to voluntarily put your posts in the silly claims forum :naughty: – it’s supposed to be a place of shame and exile for claims that not only aren’t supported, but aren’t even logically coherent. Your speculation isn’t incoherent, and thus in the hypography scheme of things, not “silly”.

 

Hopefully some interaction here at hypography will grow your scientific knowledge – that you’re here suggests that you’re looking to do that – and get you in the habit of researching and sharing your knowledge with your fellow hypographers.

 

On to the body of your post:

The Sun isn’t on the outskirts of the Milky way galaxy – it’s about half way (25,000 ly) from the center, near (approximately 50 ly from) the galactic plane.

 

This is in what’s known as the galactic habitable, or “goldilocks” zone where life like ours seems most likely. Much further out, and the lower density of supernova remnants makes for not enough heavy elements for our chemistry. Much further in, and radiation from the core is deadly to life like ours. The galactic center is not a life-as-we-know-it friendly place, which is not to say that intelligent life couldn’t evolve there, but that if it did, it likely wouldn’t much resemble our kind – perhaps some very weird thing like Steven Baxter describes in his 2004 SF novel Exultant, but not the DNA-y stuff we’re used to.

 

Perhaps they haven't bothered to check because it looks so...remote almost. Maybe it's hard to get here. Just like it's hard for us to travel to parts of the ocean.

It certainly seems like beings like us traveling between stars is very, very hard, much harder than book and TV space opera (STrek, Star Wars, Battlestar Galacctica, etc) can lead one to assume.

 

Analogies between ocean and space travel, however, are IMHO deceptive. The major effort in space travel is accelerating at the beginning and decelerating at the end (or perhaps accelerating and accelerating continuously, with a sufficiently advanced technology) so traveling long distances is not proportionally harder than traveling short ones.

 

Taking our own civilization’s current progress as a guide, we or any other eventual spacefarers are likely to have gotten pretty good images of where we want to go (including spectroscopic analysis of target planets’ chemistry) from advanced telescopes long before attempting to physically go there. So, while it’s far harder to get from a planet around one star to one around another than it was getting from one continent to another 500 years ago, we have much better maps before we even start.

Thank you both for your answers :D very interesting.

 

Do you think it's possible we may be the first intelligent species. I guess someone has to be, right? I came to the conclusion that we're on the 'suburbs' of the galaxy after watching Carl Sagan's Cosmos, maybe I should of looked more into it first.

I think that when cosmos was made the idea of galactic habitable zones hadn't come into use yet. Sagan might have not been familiar with the idea.

 

For a good over view of the idea of the galactic habitable zone see this http://en.wikipedia.org/wiki/Rare_Earth_hypothesis

Actually it's not that rough a journey. Once your species gives up on rockets and other childish things you'll see.

 

Of course you do have a long way to go before warping space and time comes as easy to your kind as it is for ours...sorry not allowed to help with that there are laws against helping such primitive cultures with such things.
