Is it technologically possible for Aliens to travel to Earth?
Aliens as in micro-organisms hitching a ride on comets? Yes, it is possible.
Aliens as in sentient beings on a distant planet on the other side of the galaxy first discovering us and then travelling here? No.
How the hell could anyone answer this.
It's technically possible, but it'd take a very, very long time. The problem is that it'd take so long that it'd be only chance if it arrives at the same time there's humans on the planet.
I was basing my answer on currently known science. Wormholes are science fiction.
Hence why I said "How the hell could anyone answer this".
How the hell could anyone answer this?
Oh this is going to be good. Please tell me exactly what in the general relativity that mandates that wormholes can exist.
Dis gun b gud
By realizing that on Earth we already have:
- technology for sending craft outside of our solar system
- biologically immortal species
- at least a couple billion more years of existence as a planet
If it's possible for us to have gotten to this point, it's possible for aliens.
Whoa hold on there buddy. Wormholes are not a natural extension of spacetime.
They're an imagined extension of spacetime. IE something that might be possible, but there's no current evidence that it is.
It's firmly in the 'we don't know' category of things.
There are three categories of things:
Things we think we know
Things we know we don't know
Things we don't know that we don't know
Wormholes are in category 2, and category 3 is unknown. Category 1 is things like general relativity.
then you read the text I did give:
>It's technically possible, but it'd take a very, very long time. The problem is that it'd take so long that it'd be only chance if it arrives at the same time there's humans on the planet.
And bam, you find out that's the answer I gave.
I see two conceivable possibilities here:
a) This hypothetical alien race developed and evolved on their home world much like we are doing now. They went through seemingly endless periods of social and economic upheaval while their society grew and flourished. Eventually they overcame their petty worldly concerns and embraced a future in space. They developed faster than light transportation and went out into the galaxy in exploration. I find a race such as this must be benevolent, and the probably adhere to a strict non interference policy with lower lifeforms (humans), which is why they haven't contacted us yet.
b) This hypothetical alien race stole their space faring technology from another race during some kind of conflict. In which case they are totally unpredictable, probably extremely hostile and we are basically fucked when they come to conquer our world.
>- at least a couple billion more years of existence as a planet
That's factually ambiguous.
While the planet might be able to sustain life as we know it for that long, it more than likely won't be able to sustain humans for that long.
With current technology we can send people to Mars if we really wanted to. We might not be able to get them back. They might not be alive by the time they get there either.
The only realistic form of alien life entering out planet is microorganisms on comets and such.
Yeah, the text you gave was stupid and irrelevant. First off who cares how long it takes if it's less than the remaining existence of Earth? Say it takes 1 billion years. Well then they made it. Also who talked about humans? This planet existed before us. It'll probably exist after us.
It's a 10 word question into which you read so many distracting assumptions. Right here, right now, we have the technological capacity to allow a species alien to some world to travel to it. The technology has already been created once, so it's possible for it to happen for aliens too.
> it more than likely won't be able to sustain humans for that long.
You are not "Earth." The ball of rock is Earth. The question has to do with the latter.
Seriously, reverse autism in here. The question is about technological possibility, not practical relevance.
Well I care about humans, so I consider that a problem for us.
I disagree that we have the technology to send a living human to a distant part of the galaxy. Even from the nearest star system. Unless by alien you mean extremophile bacteria that is. I have to assume that an organism of sufficient intelligence to construct spacecraft will have similar biological needs (of basic things, like energy required to sustain a biocomputer wherever they keep their brains)
It depends on their technology. If we can land a probe that has been build ten years ago on a comet billions of miles away I'm pretty sure we can also eventually build a starship and land pods on planet Omicron Persei 8. If we can do it, so can any species that's on par or beyond our technology.
>I disagree that we have the technology to send a living human to a distant part of the galaxy.
I didn't say we could send a living human. I said we could send a species alien to another place to said place. As above, we have biologically immortal species on earth.
"Alien" is not "human analog." It's a lifeform not native to that place.
You assume that human considerations matter and you assume that it has to be intelligent. Why not just ignore the OP entirely and talk about Linux?
>Einstein–Rosen bridges are connections between areas of space that can be modeled as vacuum solutions to the Einstein field equations, and which are now **understood to be intrinsic parts of the maximally extended version of the Schwarzschild metric**
Well it's a subtle note of definition, if an alien travels, it is different from an alien being shipped, or brought.
It doesn't even have to be THE definition, so long as one of the uses of travel includes the meaning of movement of sentient lifeforms, then it's a valid point. A general understanding of what the OP meant over the letter rather than the spirit of the question.
Whatever, point is we made the right calculations to send a probe in the right direction and make it land somewhat safely by using some gravitational voodoo from Earth, a passing comet and stuff. Hell, we send a rocket to the moon with a computer thats as powerful as a graphical calculator and that was in 1969...
>point is we made the right calculations to send a probe in the right direction and make it land somewhat safely by using some gravitational voodoo from Earth
And Mars, but it required countless recalculations and adjustments, hence why it stayed in orbit around Earth and Mars. It wasn't a fire and forget kind of probe.
>alien civilization will develop like i want human civilization to
Yfw we encounter aliens with advanced space travel and
>They enjoy recreational murder of the lower class
>Their medicine is religious and herbal, and only afforded to the strong and wealthy
>Their computers are 1990s-tier at best, only good enough to manage starships
>They spent that spare time not making better computers on making better weapons and countermeasures
>Their most revered concept is mortal pleasure
>They spare the fedora tipping edgelords to keep for cage fights and kill the rest
Yet travel through wormholes remains a story-tale.
Aliens would be great for humans. We could finally rally together to hate something on another planet instead of each other.
External conflict brings people together, while things like opinion wars tears societies apart.
They'll send artificial probes capable of blending into human society and luring humans into processing plants to be liquified, shipped back to the mothership, and served as a rare delicacy.
>Go into black hole
This kills the man
>Come out of white hole
Yeah, at the end of time
>Maybe in same universe, maybe not
In the same universe, only after a very, very long time since gravity distorts time.
The latest theory is that black holes become white holes the moment they collapse, but since gravity distorts the time completely, what is instantaneously from the black hole's perspective is billions of years from the perspective out side.
Or at least try.
To boldly dick what no man has dicked before.
This is a thoroughly debunked idea. White holes don't even exist.
If they were like that we'd kick their ass. Like how napoleon armed the lower classes and raped his feudalistic- private army neighbours.
The history of europe is pretty much shitlords like those getting slammed by peasants. And then millions and millions of people dying
>External conflict brings people together, while things like opinion wars tears societies apart.
And so the Union of Solar Energy and Free Nations, Human Reform League and the Advanced European Union combined forces against this Celestial Being, bringing world peace to us all.
>I have read the whole of reddit, and i can tell you as a matter of fact that it is impossible for Aliens to come to earth.
That is your level of autism.
Yes, they can, but the ones who are here have always been here. Is like if monkeys started evolving tomorrow. We would give them Australia and tell them that's all there is. Take good care that they don't mess around with ships too much, but leave them be. (And study them, and fuck them when no one is looking).
Well if they just came out of the blue and started nuking us, yeah we'd be fucked.
They'd probably not bother with nukes though. they'd redirect near earth objects and use the kinetic energy of those to extinct us, then swoop in and use the natural resources.
However, they might care about just killing the infrastructure and then enslaving us.
Thanks for your epic wikipedia knowledge, shitstain.
If they're the same object, then how can you go into a black hole and then out a white hole and consider it travel?
Nevermind the whole being squeezed through a fucking singularity.

No shit, I already pointed this out.

Did you even read the article? Or the sentence I quoted. The existence of Hawking radiation implies that they both are the same thing.
>Aliens as in sentient beings on a distant planet on the other side of the galaxy first discovering us and then travelling here? No.
It's incredibly unlikely, but why would you say it isn't possible? For all you know they've already found us, have the technology, but just don't care about some race that can barely put a man on their moon.
The chance of other life being in the universe that is as intelligent or more intelligent than us by our standards and is both similar to us in ways that make them not so alien that they're only intelligent life by the most surreal of standards is infinitely high, assuming the universe truly is as massive as it should be and appears to be.
The chance of said life also coming into contact with us is right now or anytime in our lifetime is so astronomically low it falls into the area of event chances of that a big bearded guy coming out of the sky thundering about sinners and shooting lightning at people is around.
At some point in our distant future we may develop a technology to find life forms on planets galaxies away like a type of sonar, and we may develop space travel which allows us to go faster than light and arrive there at a reasonable time frame, but we are nowhere near even the age of the birth of that level of technology and even if you had a prosthetic body and could never die of natural causes you still probably wouldn't live to see us advance that far.
While it is technologically possible for Aliens to travel to Earth, the likelihood of that happening is so low it isn't even worth worrying about, and the likelihood of them being any kind of alien we'd want to make contact with at all is a lower chance than the lowest amount of anything you can comprehend just above nothing.
There could also another Earth where Hollywood was right.
There could be another Earth where monkeys never evolved and instead they now have evolved cockroaches ruling the world.
There could be another Earth where we already co-exist with an alien species.
Sky is the limit when it comes to hypothetical stuff.

You're assuming there is no unknown unknown technology that would allow them to travel here more efficiently. Our knowledge of the universe is way too limited to say for certain that it couldn't be done.
Nah bro. We need a few things to be able to leave the solar system. Or hell, even just to live in space.
1. Artificial magnetic field to protect from radiation and/or some type of wonder material that can block radiation as well as lead or better without the downsides (poisonous and heavy as FUCK, good luck lifting tons of lead into orbit).
2. Space elevator (mass production of great lengths of carbon nanofiber wire)
3. Extremely efficient recycling system, nothing can be wasted and everything would need to be reprocessed and reused including your piss and shit.
4. Propulsion without the use of a propellant. This is huge. Your intergalactic starship can't be running out of gas.
5. Method of generating or collecting sufficient energy without fuel; no matter how much fuel you take, it won't be enough. Probably super efficient use of electricity combined with ultra efficient solar cells would do it, but only if you're close enough to stars. Apparently there are stars in intergalactic space according to new studies, so it might not be so bad.
6. Better spacesuits (think Gundam's normal suits) or genetic modification to survive in extreme low pressure

Assuming we are right about the laws of physics, what is to stop them from just living and reproducing on a giant ship until they get there? Not that they'd want to do that, but it's possible.
This is why I'm interested in UFOs
Most people and most movies always try to suggest that
>there is no proof at all
>only blurry photos
>only crazy people
Yet, we never hear about all those cases that are the opposite.
For me radar data and physical traces are evidence enough.
We just don't know who created them.
It could have been us, the russkies, the chinese or maybe aliens.
They don't even have to break any laws at all if they
>send unmanned probes
>cryogenically freeze themselves
>use a Alcubierre drive
>aren't of extraterrestrial origin
>are located somewhere close to us
If aliens look even a bit fuckable, we'll fuck it.
If it isn't we'll probably hate them. Bringing world peace through collective hate.
Either way it's a good thing.
The only issue would be them being hostile and out for our resources.
>Military generals and admirals aren't credibile
>Astronauts aren't credible
>Radar data on tape isn't credible
>Radiation at landing sites described in government documents does not count as physical evidence
Seriously, the ayy lmao crowd needs to look at the facts staring them in the face.
Awh man i fucking love the idea of aliens. This thread is an awesome read. Does anyone have the picture about what you should do if you actually do make first contact? Seen it posted on various boards.
As an O-4 I can attest that Admirals are always 100% full of shit and it's almost the General's entire job to lie through their teeth.
Radiation at landing sites doesn't mean shit, nothing on record or documentation means shit, Astronauts are infamous liars and a number of them have become "ancient aliens" faggots who make up bullshit on the spot.
So no, none of that is credible at all.
Laws that are defined by us, stating what we think is happening. But what if we were wrong? It wouldn't be the first time, otherwise the earth would really be flat and there would be some mystical guy up in the sky who created us...
>Astronauts are infamous liars and a number of them have become "ancient aliens" faggots who make up bullshit on the spot.
Or maybe they know more than your NEET faggot ass, having been selected for their superior intellect, physique, mental stability, and clearance for such an important job as going to space and working on NSA satellites?
If we're right about the possibility of a warp drive and a currently unknown element to the equation that allows to work has been discovered by them? Yes.
If they managed to create a self-sustaining vessel which can allow them to travel in extrasolar space for countless generations of their own history, replenish and/or recycle resources for thousands and maybe millions of years, and power a sublight drive that gets close enough to make interstellar flight an option for them? Yes.
Is it plausible? Not by our current understanding of things. Is it likely? Same answer. Is it likely they'll come here? Not unless we give them a reason to, and we still have a long time before we reach anything that might via unmanned craft and broadcasted information.
What planet do you live on in which that would be released to the public?
Do you even understand why we have things like olimpics/sports/tv shows?
Who do you think you are that you would be part of the group of humanity that has an access to that?
What would people in 1492 thought about ''oh, yeah, the queen's guys have discovered a new huge piece of land on the other side of the sea"?
no. i even recently made a post about it.
it is sad to see that believing in ETs became a form of religion, just like believing in a God, a ghost, or your kawaii alicorn waifu. altough it's based on scientifical theories.
it is a belief propagated essentially by holywood that has got amplified after the last world wars, to make us feel better since we have the potential to nuke life from earth because of a retarded political ideology in conflict, to believe life exists somewhere else and not just on this rock floating around a star so whatever happens to this one, eh?
it's just like a religion. regardless the scientific and technological advancement an ET civilization could have, like a fucking death star or anything bigger that almost travels at the speed of light, this simple galaxy is just too large for them to ever meet us. barely communicate with us.
if you know Drake's equation and apply the current numbers, which is completely valid and true, we have only a few "neighbors", like mere animal forms in the MilkyWay (not the candy, the galaxy) with about a million of planets like earth with the potential of having at least microbial or bacterial lifeform. not talking about a breathable atmosphere for us, and that is insanely optimistic. all numbers combined... wow, it's fucking nothing, especially if you include earth in those statistics.
in final, we must stop caring if there's someone up there looking at us, and focus on our own planet, and our Solar system.
aliens are scary? we're taught to be scared from things we don't know or understand. but it is scarier and even less comfortable to see the truth: to know that we are alone, even an ant lost in the middle of antarctica has more chance to meet someone else than us or any advanced civilization to meet us.
Technology can be utterly advanced, but you can hardly travel faster than light. it's physics, it's science. it's the laws of the universe and math.
>but it'd take a very, very long time
>implying we are capable of realizing time
did you ever think of the possibility that maybe we are just a plain stupid species that doesn't realize where, when and how we actually are? There could be a lot more around us but our brains are just unable to register it.
And? If they travel at pretty much light speed (like 99.999% or something) then they can travel 100 million lightyears in well... 100 million years. That's a long-ass while for us but maybe it isn't for ayylmaos
Don't add words to what i said, try to think what would it mean for your life at the office that there are actual green men walking the planet. Wouldn't that change absolutely everything in how we approach life? What have we been doing through movies and culture these last 50 years?
>A clear video in the visible spectrum on modern equipment.
According to the documents released by many, many governments around the world, the phenomena screws with anything that isn't analogue. Pic related is a photo from Italy in 1958. Best quality one I am aware of.
>A physical piece of UFO
You'll need to get into the NSA, CIA, DIA, or Air Force for that.
>Scholarly confirmation, rather than anecdotal evidence.
Project Blue Book
UK MoD files recently declassified
Chilean Military files recently declassified (these include video)
You won't get mainstream academic confirmation because the matter is still classified and people would lose their jobs / get thrown in gitmo.
But it shows that UFOs (as in Flying Saucers) exist.
The FBI, CIA, NSA, the Army and even France takes them seriously.
And yet we are always made fun of if we say they exist.
>A clear video in the visible spectrum on modern equipment.
even if a clear video gets released it will be debunked in hours
due to the endless amount of faked videos everybody thinks that
it could be faked => it is fake
And what if UFOs are always blurry? (due to their propulsion technology that bends space around them)
Most credible cases describe their path as
>like a falling leaf
and they are interfering with our technology (see Malmstrom base or Teheran UFO)
so it could be that our cameras won't function close to them
>A physical piece of UFO.
gets confiscated by governments pretty quickly
they have to check if its a part of an enemy spy plane and thus they take it away
>Scholarly confirmation, rather than anecdotal evidence.
In a field where you get fired for asking questions related to UFOs you won't get scholarly confirmation.
And how are radar data anecdotal evidence?
addendum to this because most people don't realize it already
The government is controlling all sorts of media.
The CIA is controlling most of them since the 50s (see Operation Mockinbird), that's also the time period where they started to bash "Conspiracy Theorists" (anyone that scrutinizes the official version of events)
The NSA is listening to all their calls and e-mails and have ways to keep them in check if they want to release something.
They control what information appears online (see the DISRUPT DENY DEGRADE DESTROY DECEIVE papers Snowden leaked)
no. not even if they send millions and millions of spaceships in all directions the chances for them to find a planet able to host life are small, even smaller if they try to find intelligent life.
our biggest luck here is our radio emissions, more like a big noisy thing that makes our solar system different. we send signals. there's something here.
that increases our chances by a few percents, for the reality:
it is simply better to consider we are the only known life form of the universe. let's make sure this one is intelligent.
Let's say I believed you.
What difference does it make? Did they leave us anything, tell us anything? Did they attack us or give any indication of what their aims might be? I just don't see what the big deal is.
Also very narrow minded of life out in the universe. there's no life in the universe it would be an awful waste space.
Of course it's POSSIBLE but most of them would probably have to travel for what seems like forever to get here.
They'd either have to be biologically immortal or have the ability to put themselves into stasis. Also the ability to sustain themselves while in space, this would require a massive ship depending on their technology level. If they ever show up, it won't be some tiny saucer it'll be FUCKING HUGE and we'll most likely see it coming.
Going into the theoretical technology part of aliens, alien civilizations can exist that are millions of years older than us. They might even be able to fold space in a way that the distance between the start and destination become almost zero.
That's a fucking far shot though, at best I think aliens would use some kind of sub-Warp Drive where they create a lighter than space bubble around their ship.
>Information can't travel faster than light.
Governments take them seriously because they're not extraterrestrial
UFOs originate on earth. They're not spacecraft, they're atmospheric vessels designed for and by humans.
All supposed alien carcasses from UFO crashes were burned/mangled people and monkeys in flight gear.
If they're here, they've solved the energy and physics problems around FTL. This sort of technology could get us off gas/coal/oil. That is the $7 trillion dollar problem with official disclosure.
You know , i have wondered about this myself.
What if UFOS are just flying cars?
Think about it for a second, it's the worst idea ever to give flying cars to everyone... BUT, BUTTTT, its not to give them to very rich people who can pay for their development/keep the secret.
>no. not even if they send millions and millions of spaceships in all directions the chances for them to find a planet able to host life are small, even smaller if they try to find intelligent life.
But the chance gets far bigger if there's millions of ayy lmao civs out there. Also, we don't know about their technology for discovering earth-like planets. Humans have already discovered exoplanets as far as 27710 lightyears away from us, so it's not unthinkable for ayylmaos to be able to find exoplanets in a 100 million lightyear radius
we take seriously everything that's flying over our territories without identification. spy planes exist since decades. stealth technology is nothing new. of course it's a concern. any industrialized nation can build a stealth jet for recognition, intelligence or attack purposes. even a prototype. it does not mean it's an ET thing.
like, the B2. do you really think that thing, despite being a designer's masterpiece is worth a billion dollar? nope. you can't tell how much of these have been built nor who exactly purchased them.
more for the conspiratards, do you really think the HAARP antenna is a weather control device?
it's a AM/VHF antenna for sure, if you're on /g/ you might know how these radiowaves behave. and why an intelligence agency should own such a passive system...
now continue with your UFO, personally i'm certain that none of those are actually extraterrestrial unless you deliver me an irrefutable proof.
Does anyone ever stop and try to imagine modern life on a completely different planet, extremely similar but also dissimilar at the same time?
Like trying to imagine being an alien on a different planet who also wonders about the existence of other aliens and what their lives must be like.
>not spy planes
No, really, development of disc-shaped aircraft has been public knowledge for ages.
Everyone wants VTOL and a craft that can move in more than one direction that isn't a fucking chopper
