Hey guys, what are your thoughts on the existence of extraterrestrial life and the potential involvement of governments in concealing or studying such entities.
Life probably exists somewhere else.
That doesn’t mean they visit us in secret and there’s a conspiracy to hide it.
It’s two very different things
Doesn’t mean they don’t either. :)
I think it’s likely they do. There has been so many sightings through the years and so many stories that I believe no smoke without fire, so to speak.
It’s also what we would do. We (humans) would have similar strategy if we had similar technology to visit other planets.
Also, life and intelligent life are two different things.

I’m dubious of faster than life travel being for reasons beyond our understanding of physics. If there were a reasonable way to do so 1 race anywhere in the galaxy could have colonized the entire galaxy or at least a substantial portion thereof in only a few million years. If it is possible it seems to suggest that life is so rare that there are very few forms of higher intelligent life in the galaxy at any given time and probably relatively few ever.

I assume other life exists somewhere, because the universe is practically infinite in size, but I also assume that we will not meet them, because the universe is practically infinite in size.
Basically my thoughts. The speed of light, while the fastest thing we know, is as slow as smell on the scale of the universe. Any race of beings able to get here, check us out, and leave, would need technology that would break physics as we understand it. Not to say it’s impossible, but we’ve now firmly stepped into beliefs, rather than anything based on observable data. Also, the notion of a race being so advanced they can travel faster than light accidentally crashing on our planet is pretty silly to me.
I like the space travel explained in three body problem. Soldering about folding up dimensions.
The universe is big enough that life probably exists in other places. Anything advanced enough to reach us (an extraordinarily difficult feat) would not be dumb and incompetent enough to fall under the control of people, and people just want to believe in something fun to compensate for how boring modern life can be.

Never underestimate the stupidity of smart people/potential other sentient beings.
Also good to never underestimate human negativity bias, where the brain remembers bad things far more than it remembers positive things.
Look at air travel. We invented it over a century ago, and have made it safe enough that a single failure out of thousands of successful flights becomes newsworthy.
The statistical likelihood of stupid-yet-capable aliens happening to fuck up that badly is very small.
Absolutely! I mean primarily that just about any sentience that humans can conceive of is likely to experience some failure, even if down to just statistics. Even our dieties are fallible. So, it seems reasonable to expect that an intellectually superior sentience could make a mistake, leading to loss of craft to primitives like us. Then again, maybe I’m too dumb to conceive of a non-fault-prone intelligence.
Extraterrestrial life = yes. It’s a big universe and the chances of us being the only life in the entire universe is slim.
Aliens visiting us = no. For the same reason as above. It’s a big ass universe.
Governments being able to hide aliens from us = lol no. If aliens had the tech to travel a million light years to visit us, they’d have taken over the planet in an hour.
I lean towards no, which is a minority scientific position. The Fermi paradox is strong evidence against technological aliens, and of all the evolutionary history we have immediate abiogenesis is the most weakly supported. It happened early, but there’s still a 10% chance of a thing randomly happening in the first 10% of geological history (to oversimplify the math).
If it’s not that, it’s eukariogenesis, but that seems a bit more inevitable given how cooperative bacteria can already be. The development of technology seems inevitable once a thing by chance becomes smart and dexterous enough, and every other step along the way has happened more than once. Earth-like planets are still thought to be abundant.
Edit: Oh, and no to any conspiracy. It would be really hard to hide obvious alien life, and there’s no real motive for all world governments to unanimously do so. And conspiracies don’t exist, because we’re too disorganised to keep a huge secret for long.
I definitely believe that aliens exist, but I very much doubt that they have any interest in contacting us. I find that lot of the discussions around aliens fail to take into account the sheer vastness of the Universe.
- Universe has been around for close to 14 billion years
- Milky Way in its current form has been around for about 8~9 billion years
- Life on Earth appears around 4280 million years ago
- Humans start evolving around 2.8 million years ago.
- Use of language appears around 100,000 years ago
- Writing is invented around 5500 years ago
Inventions of language and writing are the landmark moment here. Before language was invented the only way information could be passed down from ancestors to offspring was via mutations in our DNA. If an individual learned some new idea it would be lost with them when they died. Language allowed humans to communicate ideas to future generations and start accumulating knowledge beyond what a single individual could hold in their head. Writing made this process even more efficient.
So, after millions of years of life on Earth nothing interesting happened. Then when language was invented humans started creating technology, and in a blink of an eye on cosmological scale we went from living in caves to visiting space in our rocket ships. It’s worth taking a moment to really appreciate just how fast our technology evolved once we were able to start accumulating knowledge using language and writing.
Now let’s take a look at how technology itself has been evolving. Once we discovered radio communication we went through a noisy period where we were leaking a lot of our broadcasts into space, and within a span of a 100 years we started using more efficient communication, and encryption. If somebody intercepted our broadcasts today they would look like noise because they’re designed to look like noise.
Our society today is utterly and completely unrecognizable to somebody from even a 100 years ago. If we don’t go extinct, I imagine that in another thousand years future humans will be completely alien to us as well.
So the period during which intelligent life would be recognizable to us during its course of evolution is infinitesimally small! The time between creating language and becoming an advanced technological society is measured in thousands of years, while evolution of life is measured in millions of years. The chance of two different intelligences finding each other at exact same stage of development where they might be able to communicate is incredibly unlikely.
I would also imagine that the biological phase for intelligent life is rather short. We’re likely to develop human style AIs within a century, and they will be the ones to go out and explore the universe. Meat did not evolve to live in space because we’re adapted to gravity wells. An artificial life form could be engineered to thrive in space without ever needing to visit planets. This is the kind of life that’s most likely to be prolific in space.
Furthermore, post biological intelligences would likely be running at much faster speeds than our mental processes operate on. What we consider real-time would be what we consider to be geological scales.
For all we know the Universe may be teeming with intelligent life and we just don’t recognize it as such. We might be like an ant hill next to a highway looking to see if there are other ant hills around.
I really can’t imagine that advanced civilizations would have much they could learn from us. We might be a curiosity at best to them, but it’s more likely that they would give as much consideration to us as we do to an ant when we pass it by.
