Can Life Exist Without Water? Biosignatures with Janusz Petkowski 

Great point about not needing to define life when you are looking for it. Find some anomalies and work from there!

One thing I MOST respect about this guest is that he ADMITTED that he had no one specific DEFINITION for life. We as humans are too obsessed with DEFINING things and we get very @n@l retentive about it and reject anything that does not perfectly fit how we have decided to "define" something. In the real world things just ARE THE WAY THEY ARE and the universe does not give a d@mn how we choose to "define" something.

32:30 "Life is a planetary phenomena.." The nomadic Space Whales of the Omega Centauri cluster would like to have a word! 😅 Great episode, as always!

Lol JMG i do love that you’re so open about your microbial universe biases. I definitely agree with you, and believe it makes perfect sense. I hope that within my lifetime we’re able to take microscopic pictures of both Mars and Venus and hopefully find life on one of the two. It’d be even cooler if we found life on Titan tho, both literally and figuratively.

As a long time Polish JMG fan I am so happy to hear Dr Pętkowski featured on this show

Great point about Europa's known old age making it a good candidate for life when combined with the factors that we always talk about. I had never heard this point before!

This video was a spectrum of slamdunks! Thank you!

Oh my god this is the topic I wished for so so so so so much!!! I just love astro chemistry I just pure bliss for me!! Thanks so much for bringing us so great talks so consistently ❤

Woo hoo! Event horizon! Thank you for doing what you do! 😊🌎❤️🕺🏻🐶🚀

Nothing better than watching Event Horizon and having some coffee in my Event Horizon mug! Thanks for the episode!

That was the first time I've heard John burst with laughter. Made my day, it's definitely on a slum dunk spectrum now :D

This will have my brain working in overload mode.

Fascinating stuff and the Polish accent at its finest lol

"You'll know it when you see it!" would make a good t-shirt slogan 😂😊

With water being so common, it seems like the accelerated path. It would be interesting to be proven wrong.

Fantastic subject indeed! Thanks a bunch for the interview, John!!! 😃 Stay safe there with your family! 🖖😊

I love Event Horizon. Just love it. Nothing comes near.

What a delightful interview with Janusz Petkowski! It is interesting to consider phosphorus as possibly an element that isn't needed for life but rather might be a secondary element life might adapt to. Also, great question by JMG regarding arsenic based life!

very cool thanks for the episode.

You’re an inspiration with these keep it up 👍🏼

Great video and information !

What a fascinating interview!

38:53 I’ve never heard JMG laughing this hard, and I see why🤣

Excellent episode 🦠

Many years ago, I remember Asimov and Sagan explore back then the chemistry of life and absence of water, carbon or nitrogen. Interesting video. 👌

Water is very common throughout the Milky Way. I can’t imagine life without water.

I love the title of this episode, but an even better title for a future episode would be to contemplate if all variations or potentialities for life require water as a firm condition to live or BE alive...

As a living being myself, standing outside in 30 degrees Fahrenheit… I just can’t imagine life existing on Titan. I understand it would have to be very different, but even so, I just can’t fathom it.

Awww yeah I was just thinking about this topic the other day!

Wow, John, that was deep (future of earth). I'm crying now.

This is good stuff.. I suddenly don't feel so far out in my thoughts.. Life is here.. and we have a duty to spread it among the universe.. T.LaMore

interesting as usual

Fantastic - what abut the effect of low temperature on the ability of these building blocks to arrange and mix?

Thank God it’s Thursday. Look forward to this all week. You’re not as prolific anymore on jmg! Me no like! No personal life for you John, I need intellectual stimulation. JK! Love everything you do brother

I keep coming back for the laugh. John, I would be honored to have a smoke with you one day

What's the name of the outro song? Banger🔥

Janusz mówisz ciekawie ale most striking thing dla mnie jako Polaka to jak niepolski masz akcent. Dziwne jak bardzo nie mogę get over it ;) Impressive. No hard feelings, regards :)

The song by TIffany "I think were alone now" comes to mind.

Actually, it seems to me that there is a basic principle that would make it much easier to theorize about potential environments that life can exist. The only difference between microscopic life and multicellular life is just the fact that there are fewer organic processes going on inside microscopic life so therefore there is far less of a likelihood that there would be anything about a particular environment that would make it impossible for microscopic life to exist. That being said, microscopic and multicellular life are fundamentally the same and therefore the only thing needed to allow for multicellular life to exist in any environment where microscopic life can exist is specific adaptation to that environment. So it just makes sense to assume that you could find advanced multicellular life in any environment that microscopic life can exist, and buildup a library of possible life supporting environments based upon environments that microscopic life can exist alone with the assumption of the possibility of more advanced life.

Thanks for another thought-provoking episode! We gonna get any more sentient opossum lore? 😁

Ammonia and hydrogen florine version of jmg is water based life possible

Rrrright on.

So ammonia amd formamide can be basis of biochemistry if abundant on a world? Titan have either?

There are already fish that have been found living in pools of hydrochloric acid on earth so I'm not sure why there would still be questions about whether or not life could exist in such environments.

Before I even start the video I have to try. "Janusz Petkowski" Ya-nus Pet-kow-ski Lets see if I was right.. EDIT: Yup, I was. Actually shocked I got that right.

In lab the top 4 solvents are 1 water 2 alcohol 3 acetone 4 glycerin

Starts 0:56

You know the frozen block of pee and poo that the passenger airplanes contain? Well, a starship's block would probably be dehydrated (water reclamation), and super dense (compressed for storage). But... eventually, it would build up to the point that they'd have to shoot it off into space... billions of years ago, and accidentally on a collision course with our solar system. What if THAT'S what seeded life on Earth? Panspooia, IOW.

Last time i came this late my wife was happy

Why are you NOT on Nebula?

What up creatures of the night?!?!

David Grusch will tell us.

I can’t wait until we get to titan. And europa.

Miss water morning in the morning

Good video up to @53:15. You do realize that we can stop the sun's increasing luminosity, right?

16:33 What am I missing here? Alien language?

Sulphuric acid reservoirs makes me wonder where the green belts for each example planet and moon would be for life to be happy If Venus and Io could be moved to a place where surface pooling of whatever liquids could occur, where should they go in terms of orbit?

It would be arrogant to think not. I’m positive there could be life out there that consider water a very common resource and not necessarily valuable because of their distinct biology. Maybe they’ve got bodies made from stuff that takes billions of years of evolution or fabrication that no longer needs water and can utilize other source of matter that’s more efficient; much like car needing gas or electricity.

👽👽👽👽👽💥

Looking at our solar system it seems like planets and moons are like snowflakes and none of them are the same.

When being pressed to define life, and saying "You will know it when you see it", it becomes similar to language people of faith use

Maybe alien life is plasma or gas..

Life is water so no

1st in. Nice

That has to be the singularly dumbest question ever on the internet since Day 1

I can never figure out why the Indian accent replaces Rs with “rolling” Rs. If I can do an impression of an Indian accent by replacing Rs with rolling Rs, I don’t understand why they cannot seem to be able to do the reverse. Can anyone explain this?

THEK EETH A THLICK GHLI

methenogens

Your thleekith were so preoccupied with whether they thleek, they didn’t ghli to thlick if they hethleethik.

Great, another unintelligible scientist. 🙄

BRUH! At @16:50 I thought I was having a STROKE!
