800 stars and no sign of life but I dont get this? Basically in a nutshell the Fermi Pardox says we're the only ones here! But there's still billions of light years in the universe

I think there's other civilizations out there. The Drake Equation, which is mentioned in the Fermi Paradox article on Wikipedia, came up with an estimated 10 civilizations in the Milky Way Galaxy as advanced or more advanced than us humans on earth. Problem is that the Milky Way is 100,000 light years across which would put the average distance between these civilizations at 10,000 light years. That's just too far for anyone to realistically travel. We've barely evolved to where we are in 10,000 years, let alone have the technology to travel anywhere near the speed of light.jt222_usvery good point,I agree
The main problem is that faster than light travel, warp speed, all these things are still theoretical for us
Could other civilizations overcome the laws of the universe to create these technologies or are they insurmountable no matter how advanced you are?
What follows is that if only sublight travel is possible, and journeying to another inhabited planet takes 10,000 years, then no one would have the lifespan to undertake such a journey, you would be longn dead before you got there!
Even if you say to use suspended animation or some such loophole, would your technology and systems function perfectly for 10,000 years? I doubt it

We don't know how many planets will develop life, or how many planets will develop intelligent life. The values plugged in are guesses. Also, the distribution assuming 10 civilizations in the Milky Way would be even sparser, since you are assuming they are strung out in a straight line, whereas the more likely distribution is in a torus (since several radii around the galactic core contain levels of radiation much too high to allow any type of life we can conceive of to exist.
Wasn't Mr_Geezer using this theory in one of his arguments about aliens yesterday?
Sounds similar, at least.
they have a point cuz if there were civilizations much older than us and way more advanced creatures than us wouldnt you think they would have atleast found us by now. im sure there is other life in space just not as advanced as us. such as microbes and stuffs on other planets.papageorgio22
The Milky Way is thousands of light years across... :\ Not only would they have to be at least thousands of years older than us when their signals were sent out, they would have to be in the same galaxy at least.
Then they would have to be still around when we went looking for them, if they had not yet gone extinct.
There is life on other planets. No doubt about it. Might be as small as bacteria. But its still there. And have they ever thought that we might be the oldest civilazation? Some alien dude is saying the same thing as that just cause we dont have the tech. to get out of our own galaxy.Shade-Blade
Exactly. Don't forget that not only is this a theory, there is a CRAPLOAD of assumtion done when it comes to variables.
What if stars the Sun's age were some of the first that had the right amounts of the right elements to support life as we know it to begin with? And what if the average time for self-aware life to form on a planet is 2 billion years?
Could make us one of the first, and if intergallactic travel is never possible it messes with things even more...

Well mankind has been advancing for at least several thousand years, and all we've done is gone to the moon.
I'm pretty sure no one had to say it...Snake, what have you done? You've created a time paradox!
Someone had to say it.
