Why would they go all the trouble to come here without ever conquering us or either way do something meanigful on this planet?

Are humans so conceited about themselves to believe a superior civilization would think abducting a few human specimens is worth the astronomically high energy required to get here?

Nue thread?

>>7990115
No chance.
If they would visit us they would have a technology far beyond out understanding.
I see no reason why they wouldn't show themselves to us or guide us

>>7990126
Because they are Aliens.

I actually have a lot of well-founded, educated and, dare I say, wise thoughts on the matter, but who cares.

>>7990126
Yes, that's how people are. So mentally fragile that they can't live through the day without some feeling of being special.

>>7990126
Why would a race who can travel between galaxies and solar systems,enslave a race who poses no threat to them.

If you have a so far advanced technology, I think you don't depend anymore on resources like water ,iron, gas and so on.

>>7990137
I care. Why don't you tell us your thoughts?

>>7990141
Why the fuck do you assume that aliens with the technology to visit Earth are inherently a civilization that does not enslave lower races or are centered around some perfect utopia without any problems or struggle to maintain resources?

tl;dr - You don't SHIT about aliens. GTFO.

>>7990141
... so you are agreeing with him?

Never know, chances are they've already been here and we missed it.

Also, chances are they landed in Japan only to run away screaming and never come back.

>>7990141
The only reason I can think of for a space-faring civilization to travel the universe is to find suitable planets for colonization or finding whatever resource they need to acquire their energy.

Since there is absolutely no reason to think a planet with life on it has more resources than any other more common planet in the universe (unless they look for oil, but that's retarded), then the only reason they'd want to look for a planet where life is possible is to colonize it.

By conquering this planet I meant doing what europeans did with the americas basically. Whether they'd want to enslave us, annihilate us, or trying to coexist is a secondary matter.

Either way they'd show up to claim the planet. If the planet was not suitable for them to live in it, they wouldn't have any reason to come here.

If they were an "humanitarian" (sounds wrong but we don't have any better word) civilization, then they'd want to contact us and teach us all the wondrous advancement they made so to improve us.

If they were the total opposite, then they'd eradicate us before we got the chance to become a problem (and it would only take a few weeks to understand that humans would be a pain in the ass for any other civilization out there).

Anyway coming here just to study humans or cows is retarded. They'd really need to have so much energy that they wouldn't care wasting it for trivialities, but I think that's very unlikely.

No, but I once saw an UFO so I'm not sure.

Sure, why not.

>>7990143
Alright. But beware the wall of text that accumulated during downtime.

The first thing you have to ask yourself, is there other intelligent beings in the universe? Certainly. Whether it's common or not is irrelevant, the universe borders on eternity and rare things happen all the time.

Then, is there other intelligence in the Milky way? Now it gets trickier, since there's a lot of variables. You can make various cases like the Drake equation, but they're statistical exercises based on something we have no other examples of but ourselves, so while they're excellent thought experiments they hold very little meaning in actuality. Perhaps life is rare. Perhaps life is common but rarely grow beyond simple organisms. Perhaps intelligent life is everywhere, flooding the galactic arms with life.

Anyway, if we assume that life is rare, then they never visited, case closed. Even if I don't believe that we are alone in the Milky way as an intelligent species, Occam's razor would say we are. But let's pretend that intelligent life is common, then the chances that our solar system have been visited seem high. Sol moves around on the galactic arm, orbiting the galactic center every 250.000 years. So even if stellar civilizations are finely spaced several of them have had the opportunity to visit Earth many times.

Now, traveling to other star systems is tricky. I'm assuming FTL doesn't work, because it's bullshit, and through normal propulsion 10% of C is a humongous challenge, although reasonable for multiplanetary industry. So other star systems can be reached.

However, would they go to study? Most likely not, contrary to what shitty places like /sci/ would say, interstellar travel is fucking hard. The challenges are too great and the time/money investment too large for simple off-world exploration missions. If they would send manned/alienned ships to other stars, it would be for definite planetary colonization (However, advanced civilizations like this would most likely be fine living in orbit around their homeworld star, and launching things up and down to a planetary surface would be a huge bother, so I'm not sure how this holds up.).

Anyhow, if they would be capable of reaching us with ships, they would also be capable of assessing the system for habitability through remote sensing. They either they came here a long time ago, failed their colonization attempts (And no relics would be left after millions of years (They would not have come in the recent past , there aren't enough stars in the galaxy for such things to be statistically probable)), or they deemed the system shitty from afar and then looked for better places. I don't find a "No, john, you are the aliens"-scenario likely either, since all geological/biological/whatever evidence point to a slow evolution on earth that gradually shaped the planet; Unless a barren earth was seeded with simple alien life, of course, but eh, you know.

Or aliens don't exist in the first place.

>>7990115
That guy's hair cracks me up every time.

>>7990258
A little note too; We aren't going to be attacked by an alien task force. An interstellar attackship would barely be able to carry ten tanks or so and a few hundred soldiers, and us surface dwellers would actually have the advantage; With unlimited supplies and cover. Just hurl rockets at them, they are piss easy to hit and don't have the time needed to redirect asteroids or other hardcore shit, and they can't carry enough nukes/thorium rods/alien goo to be a significant threat. However, if they decide to launch relativistic projectiles from their home system, then it's time to say goodbye to Earth and head to Proxima Centauri, because when they hit the continents will crack, the atmosphere will be torn off and all that will be left of earth is a sickly battered sphere. Well, nevermind, we can't possibly know anything until a couple of weeks before they hit, and we will be unable to do anything about it, The laws of physics actually forbids it.

But the universe is beautiful anyway. I'm sure it'll end up fine. In a million years our innumerable trillions of grandchildren will travel between the stars, and continue to do so until the universe quietly dies.

>>7990266
> the universe is beautiful anyway

The Universe a barren, cold, radiation filled wasteland! it would take us HUNDREDS of years just to reach anything that does not kill us if we get too close.

Hell, even Mars, our closest "safe zone" is cold and devoid of anything resembling an atmosphere, and Venus is an acid storm hothouse. Who is ot say all other planets are like this?

>>7990302
Well...

This one is proof enough that there are other habitable planets. Getting to them however, is another story entirely

Now the consequences of such, unknown

There are space aliens somewhere in the cosmos. Probably lots of them. Whether they have traveled the mass distance to our planet, I don't know. Consider our solar system is surrounded by an asteroid belt and we are an under developed civilization that could cause problems for a higher society because of our religions and national air space laws. If I were an alien I wouldn't bother with making contact with our planet. Not yet anyway.

>>7990302
Terraforming.

>>7990340
Not so simple

Two basic possibilities:

1. Aliens do not exist, or exist at technological limits that can not exceed light speed. No point for interstellar travel unless for emergency colonization or their version of Rare Earths due to immense costs related to travel and the fact that technology increases fast enough that any ship that gets sent out will most likely reach distant locations slower than future ships.

2. Aliens exist and are capable of interstellar travel faster than lightspeed, but do not know of humans because we've only been broadcasting various signals for what, a couple hundred years tops? Unless they live within 500 or so lightyears, they'd have to randomly stumble upon our planet.

>>7990354
Even if we had been broadcasting longer than that, it doesn't take long outside our solar system for the signal to fade in to the omni-present background noise.

Its going to be a fun century or two before we can more solidly figure out if FTL is even possible.

Actually, calling it FTL sounds just plain dumb.

>>7990362

>Actually, calling it FTL sounds just plain dumb.

Well, what would you call it? FTL gets the point across well enough.

>>7990362
>>7990354
I think you should just drop the idea of FTL. It violates the structure of the universe so much that the cosmos goes and cries in the shower.

>>7990365
Why did you think I called the term dumb? Its just silly to think that something can move that fast.

>>7990365

Agreed on the silliness of FTL. Even if you could move FTL, there'd be little point to unless you had near or exact instantaneous travel between any distance.

>>7990366
Because that implies that there's regular movement and velocity involved, which mentioned previously isn't going to work.

Well, of course it would work for a person that doesn't care to think about it
