Out of Pod Experience

Pretty big jump considering the size of the universe, or even just that of our own galaxy wich has anywhere from 200 to 400 billion stars and we only discovered maybe 1000 planets in the last 15 years, so it's plenty of room to build a dyson sphere and we'd never know it was there since we don't even know the exact amount of stars on our own galaxy, never mind the other 80 000 galaxies in the universe, or the ones that have existed in the past, or solar systems that no longer exist because their suns went super nova, or planets swallowed up whole by black holes....The possibilities are endless.

Even in our own solar system, wich is roughly 4.5 billion years old and likely had it's origins from somewthing else( large sun going super nova perhaps?), because the univese is 13.5 billion years old give or take, so the material that made our own solar system and everything living in it is far older and we have no clue on that 9 billion year period that precedes it's formation.





Cool but even at 3 times the population, we're only good until sometime in the next century at most, so things need to change now to allow that many people to live in one planet and do so with an acceptable living standard, even if it's lower than today, such as large houses with nice backyards and enough room for a swimming pool, or owning 2~3 cars per family or vacations anywhere in the world once a year....It's not sustainable like that.

We might already be 8.3 billion by 2030, wich is just 18 years from now, so the more on this planet the faster the number rises in less time, hence why we hit a brick wall by the next century if still stuck on this 1 planet by then, and frankly i don't see i hapening since it's a very expensive initiative, most countries are flat broke right now with huge debt loads, never mind in 100 years from now even if the technology to do so is already available....Heck it's available right now, but involves the word nuclear but given it's bad reputation( for no good reason) it's a politically and general population no go for it.

Not a big jump at all. We have the capability to search a good sample of stars, but see no proof. The Earth has been around for some time (arguably), thus if such aliens existed we would have alien artifacts right here as Earth would be an interesting place to investigate compared to most planets. If not earth, surely Mars? But our telescopes would undoubtedly detect a current or past alien presence. Yes, lots of "what if's" but I require some tangible evidence for such life, I just don't have enough faith to believe. To me, such faith, that is the greater jump, or leap if you will.

What if. What if we know nothing? imo we are in a simulation to put it bluntly. A place of beginnings, a place to start the process of maturity, not just as a collective but individually as well. One day we move on to what is more real than what we perceive around us, and that current perception being nothing more than a facsimile. The universe is simply not analog.

That's a bit far-fetched don't you think? If I had to guess, I'd say that he was trying ti open people to the possibility that life could exist in an infinite variety of ways. Certainly wouldn't hurt the funding for his research for him to do so.

A Rogue planet floating in the vast reaches of space with a highly radioactive surface supporting life? Just think about that for a moment..

I think the answer is, not likely.

Chemistry, physics, biology, science in general indicate that there are only limited conditions and means for sentient life to exist. Contrary to Science Fiction, crystalline entities and the like are about as far-fetched as you can imagine. All life on Earth is Carbon-based; whether it breathes CO2 or Oxygen, the principles are the same.

So that leaves a zone near a star without much movement in one direction or another, (it is still a fairly significant distance), in which life can exist. Many other factors are required to make that possible as well. Some of those are fortunately covered by the formation of the Solar Systems themselves.

It would be really hard to explain in detail. Suffice to say that planetary composition is subject to proximity to the star in many respects, with higher density objects close to the star and gaseous objects further out. Ice exists on the outermost edges. Comets carry that ice back into the Solar system and evaporate as they gain proximity to the star, leaving trails of gas that gravitate towards the planets in proximity to the star. Life is made possible by the whole process, not just one small part of it.

There are a huge amount of potential variations, but the principle elements required for life stay the same. The only exception to this might be in unusual systems or places where Stars are more closely packed together, or in planetary nebula, etc.. Some conditions might improve the chances of life, while others might make it impossible.

Temperature is not the only factor required for sustaining life, though I suppose the potential does exist for some very nasty bacteria to exist in such a place, but what is it going to feed on? ..where will the water come from to sustain it's life? hmmm..

In theory, the Rogue planet could collect quite a bit of water on its way out of the solar system, so that gives the potential for it to have an entirely covered surface, which would potentially create atmosphere, but not such that would sustain life necessarily. It could however result in conditions for life being present at the bottom of the Oceans floor, where the heat from the planet was such to allow that.

Completely speculation of course, and we are talking about something like Bacillus Infernus here. Potentially yes, but is it really life? Strictly speaking, it is a micro-organism, but that doesn't mean it has the potential to be anything more.

On the other hand, how do we know that the planet would do anything but release its radiation and slowly cool, creating potential conditions for life of this sort very temporarily at some point, then killing it off as it slowly freezes?

That is the more likely possibility.

Without light, solar radiation, and-particularly-gravitational and magnetic forces of the Sun and other planets, the possibility of life decreases drastically. Some of that is simply because the only factor holding the things on the surface of the planet is gravity, and the only factor generating heat is radiation from materials in a state of radioactive decay. That's not exactly ideal.

I'm not sure what is creating the geysers on the South pole of Enceladus, but I hardly think that is indicative of the possibility of sustaining life there or anywhere else.

Evolution allows creatures to thrive where they may not necessarily have originated. Thick skin and body fat allow creatures to survive in cold places. Thick bones too. People can live in a span of regions and environments, but we still can't breath water, or survive in truly hostile environments without creating a means to do so, such as environmental suits.

I would also have to ask if it actually is water, or some liquid that requires a much lower temperature to freeze. Really, all we see in those images are a spray of ice particles. that could be anything, but the fact they are there does indicate some thermal activity below the surface could be present.

Do you think if we took a Blue Whale and put it in the environs below that icy surface, it would survive? Given that whales have to surface for air, the answer would be an obvious no, unless there happened to be air down there. If their was, the sub-surface pressure creating geysers of that sort would be such that the air would be highly compressed in small pockets, cool, and potentially liquid or ice itself.

I don't see much possibility of that environment sustaining life beyond that microbial bacteria mentioned. How would it evolve? If it could evolve, what would it be capable of evolving into? At most, I can imagine it becoming some greater bacterial culture or gooey thing.

You should watch "The Raft" in "Creepshow 2", if you haven't already. I think that's about what you would end up with, based on the acidic properties and composition of the Bacillus Infernus bacteria.

Organic compounds can be read as Carbon compounds as it is representative of organic chemistry. That basically means that there is present certain elements which could indicate the potential for life there. The environment is far too hostile to make that a real possibility on anything but the microbial scale though.

Yes, I understand that much life on Earth originated in the Oceans too. Take the Dead Sea though. With a high percentage of salinity water can resist freezing yes, but given that level of salinity how much life exists within those waters?

Your quote there suggests that the water has a very high salinity of up to "...70% by number and >99% by mass." By comparison, the Dead Sea has 33.7% Salinity; somewhat less than half.

Also of note, is the relevant fact that those plumes are expelling water vapors and ice particles at "...~2'189 kilometers per hour (1'360 miles per hour)." Given that, the indication is that the pressure below that icy surface is extremely high.

As I mentioned earlier, only bacteria are known to exist in any of these conditions. That means the potential for life is limited to bacteria to the best of our knowledge.

That doesn't mean life doesn't exist elsewhere, but I think you'll fin d if you reread that article that they concluded that the potential for life there is nonexistent. The key is noting the time separation between the first and second paragraph below, and the way in which the article is written. Not a guarantee perhaps, but pretty conclusive nonetheless.



Also, Googled Geysers. Interesting entry in the wikipedia about Thermophiles and Hyperthermophiles there. Of course, you have to account for lower salinity in the geysers as well.

Absolutely correct, but my main point is that if life is found there, even if just microbial life, it completely rewrites the book on where life is possible, even in places you'd never expect it to be, so it opens the possibility that life is a lot more common than we think it is across the solar system/ galaxy and universe itself.

lol no doubt it's long, but it's mainly the first few paragraphs as the rest cover "what if" disputes. Then there are a lot of links, I don't suggest reading it all including source links and linked articles all at once.

To any aliens reading EvEO, we are good kind people, please disregard any negativity here oh great overlords of the sky.

Here's some verified sightings from just last week.

In case that's not enough, here's Astronaut Edgar Mitchell straight up telling you the truth.

Fermi Paradox over.

Heh...A planet about twice the size of earth and largely made of diamond.
