do you think it's possible life exists on other planets? be realistic & honest now:

what percentage would you give it?

Yes, of course life exists on other planets. And why would I not be honest? this is way easy to answer.

There are  300 million planets (at least) in our own milky way galaxy that could support life, and there about 2 trillion more galaxies. Life exists out there somewhere, that's a no-brainer

 

I'd say it's all but an absolute certainty. 99.99%

I think so to. But the real question is... how intelligent are those guys. This planet had simple life on it for billions of years untill very "resently" when fish, insects and animals showed up. And if not for the meteor that whiped out the dinos we may never have made the sceen.

Listen to Brian Cox talking about this is very interesting. Scary thought, but we could very well be the top dog in the galaxy.

Maybe even in the universe?

I don’t believe that extraterrestrial intelligent life has ever visited Earth, because I can not see any reason they would come here

Well, where do I begin...? GR, Stars go nova and destroy their own planets (plus neighbors) periodically. (2 every century in this galaxy)
Perhaps a lucky few that could exit from a doomed planet went to the predetermined relocation planet, earth. This is their new home.

I think the many civilizations that live in this galaxy have formed the United Planets, and they have mapped all stars and planets in the galaxy,

That sounds like a lot but remember, they have had billions - not millions, billions of years to advance. put nothing past them. My opinion,, of course.

Well, unlike others I certainly do not ridicule your ideas, while I understand that scientifically it’s theoretically not likely. Yet, no one can prove your wrong either, so while I would like to agree with you, I am on the fence and until things change that’s where I will stay.

Peace Earl!

No science can be sure. No Drake equation can. Not until we crossed our own galaxy and beyond can we start to think about if intelligent life is possible elsewhere.

All 'emperical data' are based on our own planet and our own species. We have not the faintest clue what's out there, many lightyears away.

I agree, only time and technology will give us the answers we seek!

Ok, Ill play.

https://www.nasa.gov/news-release/nasas-bennu-asteroid-sample-contains-carbon-water/

But if there are alien races living on a planet in our system and NASA knows about it we will never hear about it, since martians leads to antigravity, (bad military wise) and free energy, (very bad for elite profits and the Petra dollar).

If these two systems where developed and released to the world then the likelihood of all out disclosure in our lifetimes becomes far more likely.

[Trelane]

If there were so many advanced civilizations (as some believe) who have cracked the code of interstellar travel and survived long enough it stands to reason that we would have detected something by now.

As I continue to learn the facts of astrobiology and the uniqueness for life to even begin, I have grown far less confident in it occurring as abundantly as others. The factors involved in things happening here on Earth are pretty remarkable when you consider them. I am not saying it can't or has happened though just to be clear.

"Is it possible/" versus "Has it happened?" are two very different questions. Unfortunately, I think the likelihood of an intelligent civilization as some propose is tremendously low.

[astrobeing]

There are three things that constantly hit me in the face when thinking about extraterrestrial life. First, physical laws don't present any easy ways for life to appear and survive. We have some pretty depressing examples of this in our solar system. Both Venus and Mars could have been like Earth but instead went in dramatically different directions even though they're made of essentially the same ingredients as our planet. Beyond them we have a bunch of gas giants with crushing pressures that don't look like good places for life. So from the planets we know about it seems like the universe is great at producing planets with rocks and poisonous gases but not ones that are like Earth.

Second, the history of Earth is series of fortunate changes that either promoted life or thankfully didn't destroy it. People tend to think of Earth as being just like it is right now but when life appeared here it was nothing like how it is now and those conditions were critical to the formation of early life. There are infinite possible conditions on planets so how likely is it that any will just happen to have the right ones to produce life?

Third, who says life has to survive for any length of time? At any point the conditions on early Earth could have changed in a way that would have exterminated all life on it. An even bigger problem is that life consumes resources and produces waste products. Fortunately life on Earth formed cycles to convert waste products back into consumable resources but there is no physical law that forced that to happen. So it's possible that life in our universe usually only survives until it consumes the resources on its planet and destroys itself.

Hey Hazzard.

How smart are those guys..? Well, they got here before we got there. So.. there is that  lol

Top Dog...? that figures. I pencil homo sapiens in  to be the embryos of the galaxy. We are, after all, only 1/4 million years old and that's just a blink of the eye!
There are billions of stars out there far older than our sun and they could have intelligent life that is billions of years old. Billions, not millions.

I have found that people like to think of humans as omnipotent in this galaxy because we are that on our own planet. But it's just not realistic to stretch that any further, in my opinion, anyway. Ciao

Well spotted.  So the question should be: are there any natural circumstances where this can occur?  Is anyone a Chemical Engineer who could rule this in or out?

It may seem unlikely, but that's not the same as impossible.  Weirder things have happened: consider the odds against self-replicating chemicals evolving into DNA on Earth.  Or the natural nuclear fission reactor in Gabon: wiki/Oklo

It's a very big Universe and lots of very strange things await discovery.  Hopefully one of them is an intelligent species who'll share loads of brilliant tech with us.  I bet they've got 3D tellys that actually work!

Hey Tom, here is something that fits your thread that you may find interesting I saw this yesterday!!!

Dwarf planet Ceres could potentially sustain life: Dwarf planet Ceres could potentially sustain life (msn.com)

Considering the significant organic material on Ceres, combined with indications of its substantial water ice content, experts believe that the planet might have the essential elements to foster life beyond Earth.

Enjoy!!

It's long been suspected that life will form anywhere it can.  Whether that's at random, driven purely by chemical reactions that generate increasingly complex molecules, or whether it's driven by a god-like creative force, that's a debate for elsewhere.

Here we can consider the likelihood of simple lifeforms in the oceans of Europa, Titan or Enceladus, and wonder whether Mars once harboured life in its long-gone oceans.

This is how aliens will be discovered: not by sensationalist TV shows or shyster 'experts'.

Here is the most recent information I have found to add to this thread.

Signs of life shooting from Saturn's moon could be collected with spacecraft, scientists say: https://www.livescience.com/space/saturn/signs-of-life-shooting-from-saturns-moon-could-be-collected-by-spacecraft-scientists-say

I know one that @iAlrakisis talking about.

Not long ago, scientists thought there to be about 3,000,000 planets in our galaxy that can support life. A short while ago,
an announcement was made that said - with new photos from the James Webb Space Telescope, they have seen that
there are far more red stars than previously thought, and that made a 100 x affect on that number (3 mill) so
now there are 300 million planets in the galaxy that can support life.

That supports his 'more frequently' assertion.

It would be intersting to know how many of those planets could support human life, if we just opened the door to our spaceship and walked out on the surface?

That is the real question, many people associate a planet that may support life with that life being human life. However, I also think that most planets that could support life would not include human life as we know it.

Good post.

[Earl.Of.Trumps]

@Grim Reaper 6, good article. And if that were ever to bear fruit, we could say that Saturn's moon has life but Saturn itself is as dead as a door nail. Odd

It is natural to ponder that but sadly, there is no  way to know. And yet there may be some planet/s that you can walk on the surface, yet there is no advanced life - for now.
I just learned this recently - not 300 million planets, but there are at least 40 billion Earth-like planets that could support life in our galaxy. That's a big "Oh wow" 

"Scientists have estimated that around one in five stars like our sun is orbited by at least one Earth-like planet that could support life. Based on simulations and the mapping of our Milky Way, it is believed that there are about 40 billion such planets in our galaxy. However, this is just an average estimate and there could be many more.

It’s not as odd as it seems, it all comes down to an atmosphere and what components it’s made from. The moon is water covered, even though the surface is frozen it can’t be all the way to the bottom.

Peace Earl!

Here is an article I found today, that adds a interesting twist to when life may have first occurred in our universe.

I just read the other day, they have actually *made* a worm hole in a lab not long ago.

No. They didn't.

"Did physicists make a wormhole in the lab? Not quite, but a new experiment hints at the future of quantum simulations"

https://phys.org/news/2022-12-physicists-wormhole-lab-hints-future.html

 

"Scientists made headlines last week for supposedly generating a wormhole. The research, reported in Nature, involves the use of a quantum computer to simulate a wormhole in a simplified model of physics. Soon after the news broke, physicists and experts in quantum computing expressed skepticism that a wormhole had in fact been created."

"Media coverage was chaotic. Outlets reported that physicists had created a theoretical wormhole, a holographic wormhole or perhaps a small, crummy wormhole, and that Google's quantum computer suggests wormholes are real. Other outlets soberly offered the news that no, physicists didn't make a wormhole at all."

"Not a Wormhole"

"What physicists did was organize the basic components of a quantum computer into a specific quantum state. They were then able to transfer information from one part of the computer to another through the quantum system."

"The quantum system, and the way the information was transferred, can be described using a particular model in physics. According to this model, the kind of information transfer that occurred within the computer is descriptively similar to the way that something passes through a wormhole."

"However, the model being used has at least two limitations."

Life-sparking energy source found on Enceladus hints at alien life on Saturn’s moon: Life-sparking energy source found on Enceladus hints at alien life on Saturn’s moon (msn.com)

NASA's Cassini mission has revealed the presence of vital components for life on Saturn's icy moon, Enceladus. Based on data from Cassini, experts have identified crucial organic compounds and a potent energy source, hinting at the moon's potential to support life. 

The team has detected the presence of hydrogen cyanide - a molecule that is key to the origin of life - and an abundance of chemical energy sources. "The discovery of hydrogen cyanide was particularly exciting, because it's the starting point for most theories on the origin of life.

In 2017, scientists found indications of methanogenesis chemistry in Enceladus's ocean, hinting at life-sustaining processes. Methanogenesis, a process that generates methane, possibly played a role in the emergence of life on our planet. 

"If methanogenesis is like a small watch battery, in terms of energy, then our results suggest the ocean of Enceladus might offer something more akin to a car battery, capable of providing a large amount of energy to any life that might be present," said study co-author Kevin Hand of the Jet Propulsion Laboratory.
