maybe there's an intergalactic policy against contacting developing civilizations until some sort of conditions are met

maybe a technological benchmark we have to achieve.
a spacecraft of some kind?

You don't know how large the universe is, do you?

any life that is out there is likely hundreds of millions of years ahead or behind us evolution wise. So either the life is too primitive to be intelligent, or too advanced for us to understand.

Either that or there is life out there sufficently adcvanced to travel the stars, it just comes down to the fact there are so many out there they'll probably never find us, which I find particularly depressing.

>>2239852
I don't see any logical reason for this, beyond convenience in scifi stories

>>2239857
so are we too far for other civilizations to reach or do they just not care about us?
is it reasonable to think life could eventually travel faster than the speed of light?

>>2239852

why wait for a specie that has the full potential at grasping the technological concept required to build a craft that is able to travel at incredible speeds, we just need the fucking information and then well be like OHHH YEEAAA OF COURSE, sooner or later someone would have eventually told us how it works without alien interference

FUCK the aliens if they wont give us the information needed to advance in science, if they already know of us..

truth: large-scale space travel is not feasible - for anyone. therefore, "space empires" etc. do not exist. all other sentient races sit on their home planet, asking themselves the same question while bleeding the resources of their planet dry before being wiped out by some natural or self-made disaster

What if they were so smart they figured out everything and then were like "oh shit now what"

Maybe life more intelligent than us would have no reason to seek out other life forms,

We're the first, that's why

>>2239869
Nothing that we know of can go faster than the speed of light (except maybe tachyons.)
However perhaps in the future some form of alcubierre drive will be created. I just don't know.

>>2239869
I would assume if you have the tech to travel between stars really fast - as in wormholes - it wouldn't matter how far you plan on going. I think it's more the fact that finding the right planet in the galaxy is like trying to find the right grain of sand on a beach.

>>2239874
>large-scale space travel is not feasible

why? given current technology of course it is, but who knows, maybe in 300 years ship capable of travelling the universe quickly and easily will be like cars are today.

I mean think about people 500 years ago seeing what we have today, it'd be like magic to them.

>>2239874
right but the smart ones go to space where they multiply and build and expand and eventually at least populate parts of the milky way right?

>>2239878

It is curiosity that gives us purpose to live, its the main fucking thing, without curiosity we would not have evolved to homo sapiens, humans are a pretty interesting specie, we do silly things and other beings like seeing other beings doing silly things, it makes them feel better about themselves, therefore they have a good reason to watch us doing silly mistakes over and over again thinking about how pathetic our minds are compare to theirs

because we are alone in the universe

completey alone

;_;

>>2239857
can someone explain this picture a little to me?
i only recognize Orion's arm and the milky way

>>2239894
>>2239893
of course i'd like for it to possible, but it doesn't look like it. there is no reason for this universe to allow us to travel large distances in it - perhaps expensive sub-light exploration is the best anyone can do.
that would also explain why no one has contacted our species - they just can't.
of course, we should still focus on finding solutions, but all advanced propulsion ideas we've come up with require fucktons of energy that we just can't produce (...yet?).

prospects are looking grim, tbh.

>>2239912
I feel like your assuming we're approaching a ceiling as far as technology is concerned. Just because we don't know how to easily travel FTL doesn't mean it's impossible. Hundreds of years ago when we thought travelling to the moon would be impossible, at one stage people mocked the wright brothers for attempting flight.

>>2239912

anti-hydrogen dude

>>2239862
>Either that or there is life out there sufficently adcvanced to travel the stars, it just comes down to the fact there are so many out there they'll probably never find us, which I find particularly depressing.
or maybe there is no sufficient technology to be invented within the law's of nature to overcome the difficulties of interstellar travel.

>>2239898
But do you really know that....

I put a maybe in my post for a reason; i was talking about something hypothetical. I suggest you makes use of perhaps,maybe,might,possibly, etc, when talking about something you dont actually know for sure.

>>2239925
it's a possibility sure

god discussions like these do my head in, so many unanswered questions, we just EXIST, what the fuck man.....

>>2239862

how do you know if they dont have like a huge fucking universal radar that picks up activity and then they will just like create co-ordinates and travel there in a second? thats a possibility considering they are millions of years ahead of us in knowledge? and that we cant prove it cant be done rite?

>>2239840

The first stars could not have supported any conceivable chemistry for life.

The second stars are low on heavy materials and one can presume it's insufficient to develop complex, civilised life forms. Or if it does, they'd have a hard time doing anything with a perpetual shortage of iron, aluminium, uranium.

Sol is among the oldest of the third stars. We could well be the most advanced species in the universe, OP.

>>2239916

On the other hand we thought transmuting lead to gold was possible.

It is, you say? Nuclear fusion? Well, certainly. But it will never be economic now, would it? See where I'm getting at?

>>2239935
we're an overtly complex and highly competitive biological organism that is too aware for its own good.

>>2239929

well, my opinion is just a guess such as yours, something to add to you thoughts..

sry for making it sound like i was 100% sure that i was right

>>2239943
I don't see how that confirmed your argument at all, if anything it supports mine.

>>2239949

Suppose it's possible to attain faster than light travel but it would require to exhaust the entire sun to go anywhere. Will we be going anywhere?

>>2239942

what do u mean 1-3 stars, u mean like planetary evolution stages?

and wtf is sol? sun?

>>2239955

Big bang. Universe full of hydrogen and helium. Hydrogen and helium collapse to form first stars. First stars supernovae. Universe full of hydrogen, helium, carbon, other mid light elements. Collapse to form second stars. Second stars supernovae. Universe full of hydrogen, helium, mid elements and heavy elements. The sun is born.

>>2239955
the first stars were made mostly of H and He, they lived a few hundred million years, created heavier elements, turned supernova and exploded, the next generation of stars were made of those heavier elements, last a few billion years, created even heavier elements, went supernova and exploded, this created the current generation of stars, which are maiking even heavier elements again.

roughly

>>2239955
>and wtf is sol? sun?

>>2239953
well of course not, but if FTL is possible it can be reasonably assumed there is an efficent way to do it

>>2239967

Transmuting lead to gold is possible. Flying cars are possible. Running a power grid by an array of slaves running in hamster wheels is possible.

I don't think your assumption is reasonable at all. Some things will never be economical.

I think its just a matter of time.

>>2239959
>>2239960

finally, new important information for me that can erase previous assumptions and create new ones

>>2239971
well your assuming that current methods for doing things are the ONLY methods, regardless of how inefficent they are.

Personally I'm of the opinion that literally ANYTHING is possible in our universe, you just have to know how to do it.

i wish we could have this discussion for once without the sci-fi crowd getting their panties wet.

>mfw we conquer the universe in a post-human form, merging alien societies into us that is a benefit to both, retaining any information that's useful or valuable and discarding that which isn't. We spread throughout the universe, turning it into a magnificent piece of artwork and machinery, that can support us for as long as the universe has a star.

>>2239840
Aliens will not talk to us as long as we still believe in imaginary friends (religion). They are pretty much looking down on us.

>>2239997

Yea, the Borg are pretty cool.

>>2240003
We have time. No need to force other societies and species into it, they'll come around eventually.

>>2240008
Ok Tim, you're done for today. Time to shut the computer off.

NASA needs funding, so they make you dream about contacting alien life and shit. It's all bullshit. We will never do it.

>>2240060
I dream because NASA wants me to, it is impossible for anyone to enjoy dreaming, or even merely speculating about the future. NASA runs your mind and suck at business.

>>2240060

Not as long as people like you exist.

>>2239942
Well fuck.

>>2239857

I always feel so small after looking at those sorts of diagrams...

billions of stars in our galaxy, hundrethousands that "may" support life. Trillion billion galaxies in the universe, if not more. Go figure, we will eventually. The immense numbers beyond our comperhension says so.
