Which answer provides the most logical conclusion in numerical terms (ex: distance and time) and relies as little as possible on speculation of what alien life might do (ex: transcending biological form to live or hibernate in some type of simulated realm)

We are a relatively advanced species, yet we have barely shown the universe that we exist. Even if there are much more advanced species than us, they could simply be much further away. This is all assuming no one on the planet has actually had contact with aliens.

It only takes ~50 years proper time accelerating and decelerating at 1g to reach the edge of the visible universe, ignoring drag. Where is all the intelligent life? They either rarely exist or interstellar space travel is impractical.

Aliens exist and have visited Earth. We have been conditioned not to notice, socially.

Brother, here is the solution gathered from intel. We are in a transitionary period where most civilizations either die off or few continue to very high technology. Meaning there is an extremely low number of civilizations with our communication types and they are very DISTANT form one another which given the speed, loss and interference with which our communications propagate, makes it virtually IMPOSSIBLE for any such civilizations to get in touch.
No dumb idiot would communicate across stars at light speed. This is not communication, this is diary exchange. Aliens do communicate all the time but we have not gotten word of it because aliens communicate instantly using waves that we only used accidentally at the beginning of the 20th century and have begun clandestinely researching since the late 1940s. That is not to say aliens travel instantly. We are talking about superluminal information exchange.

What you are seeing in the gif is probably a disc shaped craft. The smaller planetary travel ones are some about 30m in diameter. The much larger interstellar ones used for main travel are much much larger. They use electrogravitic propulsion by riding a wave generated as a third wave by some form of interference between electromagnetic and gravitational waves. The craft has two fields around it, one being electromagnetic, hence what you see happening in the gif.

Yes. If we were concerned with finding alien life, there would be varying degrees of interest depending on how advanced they would be. If they were more like chimpanzees than humans, we would be a little disappointed. We might not even interfere with them at all. But the civilizations that resembled ours or surpasses ours would be more interesting. But if every civilization has this mindset of only wanting to find “advanced” species, then our work doesn’t lie in being found, but in finding them.

Mathematically, I can only recommend everyone to look at the maximum likelihood principle. Let's define the parameter pi, which is the percentage of how many earth like planets in the habitable zone have intelligent life on them (the problem is actually more complex because bodies like some Saturn and Jupiter moons, big Asteroids, ... could also harbor life and there is also a distinction between having intelligent life on it and having an advances civilization with Dyson spheres and shit, but we keep the problem simple for now, which leads to very conservative results). Let's assume we know for sure that Venus has no intelligent life, earth does, Mars doesn't. That's the only data we have (we know exoplanets but we won't have a chance to know if human like creatures would be on them).

The question is now, which parameter pi makes the observation 0, 1, 0 ("no life", "life", "no life") most likely? It is unlikely to observe 0,1,0 when pi is assumed to be 0.000000007 (the probability of a lottery jackpot). It is also unlikely to observe 0,1,0 when pi is assumed to be 0.99999. So pi should be somewhere between that. It depends on which distribution we assume, if we assume symmetric distributions like the normal distribution or uniform distribution, it is most likely to observe 0,1,0 when pi (µ in normal dist) is 1/3.

Most people think they are reputable and scientific guys when they assume that we are like a lottery jackpot, that pi is 0.000000007 or even more. But this is nots, the maximum likelihood principle would lead us to assume that we are nothing extremely special. It's likely that there is other intelligent life in our galaxy, it either never forms civilizations that would be easily visible or they are clever enough to actively remain invisible so they have less risk to be colonized by other civilizations.

>> No.9880063

Everyone who's convinced there is no paradox and the answer is obvious cites an answer that was already thoroughly addressed in the original formulation of the Fermi Paradox.
I have no idea why people are so quick to believe the physicists who've looked into this are so retarded that they never considered explanations like "the universe is very large," "we haven't looked hard enough," or "not enough time has gone by yet."
Those explanations already having been looked at and being found improbable IS the Fermi Paradox.
At least read up on it before trying to have an opinion.

This falls apart when you consider that observing (0,1,0) is conditional on not all of those numbers being 0

I've fucked up with the distributions in hindsight, as only discrete distributions makes sense (k number of planets with intelligent life out of n observations), so I should have named binomial instead of normal. Anyways, on what are the observations conditional in your opinion?

Aliens have figured out that light is a very inefficient way of transmitting information (high absorption losses). They've been emitting signals in neutrinos and exotic particles, which do not have these problems.

We've started emitting radio signals for less than a 100 years and we already have the technology to create neutrino signals. It is understandable that we haven't discovered aliens if they have likewise spent a very short period of time emitting in light.

When we discover neutrino point sources, we'll finally be able to read the alien messages.

Maybe the next step in evolution of intelligent species is not what we currently think it is. We have this idea that our technology just gets better and better and we will be able to travel wast distances across space. But what if the next step in evolution is transcending our physical bodies and reaching planes of existence we can't now even imagine. Somehing along the lines of the ancients in stargate or what not.

In evolution of life on earth at some point we came out of water and never came back to it. What if physical universe is just another step in evolution that is meant to be left behind once we are able to overcome it.

Everything is still really fucking far away though.

There are incredibly many variables when it comes to supporting life in a universe. Changing some of the values for the forces we know even by a miniscule amount would result in a completely different universe, incapable of supporting life as we know it.

I'd say that our old-ass universe has some other weird extra-terrestial beings somewhere out there, as there are billions of stars and planets, which gives room for another improbability like human life to manifest
