That's actually kind of mindblowing: The fact that we could theoretically survive without a star because of other sources of energy, like he mentioned at the end.
RensSpace actually when the sun turns red giant Jupiter and it’s moons will be in the habitable zone meaning Europas ice would melt and because the atmosphere is oxygen (but still far too thin for humans) it could harbor more advanced life. Also when the red giant phase of the sun dies it will become a white dwarf, which is very dim so it would go back to the icy/ underground ocean state of before, but it would probably have the same microscopic life as it might be supporting right now.
@@RensSpace the sun will only expand to the orbit of Mars roughly, the outer planets will be fine (maybe more radiation, but they won't be swallowed by the red sun)
True, but think about how many times it has been wrong. Just take a look at history and there is the answer. Just because it is true today, doesn't mean it won't be fiction in the future.
Aaron G. Randall You obviously don't understand the quote. Science doesn't change. People practising bad science and making scientific errors doesn't mean the science is wrong. The Greeks were quite accurate in knowing the shape and size of the earth using physics and maths. Such knowledge was lost to religious retarded people in the middle ages but Colombus went to the Americas thinking that he had landed in India. Educated people with an understanding of maths and physics always knew the world was round. Einstein's laws were only verified ~100 years after he formulated them. 2+2=4 always even if people are unable to compute it. Physics and mathematics of the universe doesn't change as far as we know. Maybe in black holes or parallel universes.
Sachin Tripathi We live in a universe of infinite possibilities, therefore the expansion of the universe can change how physics works. Nothing is permanent and all things experience change. Even our experience of truth.
Yes indeed. I truly believe that liquid water exists throughout the galaxy. And if that's so well there's the Drake Equation - and we're filling in values for many of the variables in that one. What the Drake Equation says is the probability for intelligent life elsewhere in the galaxy, Universe, Dimension etc.
kd1s Given that the most common elements in the universe are; Hydrogen, Helium, Oxygen, and Carbon its a mathmatical impossibilty that liquid water is not common. Neato fact: Top three elements in the human body are Hydrogen, Oxygen and Carbon.
Don’t forget that nasa’s going to sent some probes to not just search for water in Europa, but also search for water or ice on other moons of Jupiter which is a lot
@Dovyeon I suggest you check out this article about digging beneath the ice on Europa.NOVEMBER 14, 2018 BY MATT WILLIAMS ARCHIMEDES: Digging into the ice on Europa with lasers. After you read it tell me if you think this method can dig through the ice,
piero san giorgio Science would demand that you prove he was tired and had a cold, therefore your statement is a random guess with no evidence or proof whatsoever.
So with all this energy being put into the moon to melt the water is the moon decaying in its orbit or is Jupiter's rotation slowing down? The energy has to come from somewhere...
At first I was going to suggest looking up tidal locking, but when I looked into it, it makes no real sense. Europa is almost tidal locked (synchronous), it's apsis has a difference of 2%, and has a tilt of 1%. I don't see how it can steal angular momentum in the form of heat. Either it's core is extremely soft (like putty so small changes in gravity field can affect it), or the gravity field surrounding Jupiter is uneven. If anything I'm thinking it's IO's gravity that's causing it.
@@farmerjohn7756 Europa has an elliptical orbit around Jupiter, thus the gravitational pull from Jupiter varies as the moon orbits, creating the tides that flex and relax the surface.
Europa is tidally locked and has an elliptical orbit lasting about 3.5 earth days. This means twice a week the planet is essentially being compressed and released (generating heat just like any other form of conginuous stretching) through the force provided by jupiters immense gravitational pull on the moon, so it's not stealing energy from somewhere unless you count standing on earth as stealing energy from earth
Yes I saw a geyser photo, you could close orbit and collect samples removing the hundred year/maybe never wait for the money to produce something to melt through miles of ice.
I find it hilarious how people in the comments are so triggered and in denial about all of the "crazy science" Neil talks about. Yet here there are...on RUclips...a website that wouldn't be possible without an extremely advanced understanding of software, hardware, physics, electricity, electromagnetism, etc.....things they have zero clue about. Yet they take all that in depth science at face value simply because it allows them to drool over their keyboard and post about how flat the earth is...
ok... if there is liquid water... and turns out no life... should we plant microbial life forms that favor that environment to see if they take hold??? Creating our own 👽
I actually like the hypothesis that life could also be in the upper atmosphere of Jupiter it's self. I'd be very surprised if Europa didn't have some sort of microbial life on it
If cellular life exists on Europa it would support the hypothesis that hydro-vents were the point of origin here on Earth. If no life exists despite the presence of favourable conditions, then the alternative 'hot spring ' hypothesis is indicated, in which it has been shown that lipid-encapsulated polymers can be synthesized by cycles of hydration and dehydration to form protocells.
I love Neil because even though he has a vast and complex academic background, he can really break science down to make it easy to grasp and make it very interesting to the average Joe. Also, you can have chemosynthetic life forms(like "tube worms") in deep sea hydrothermal vents - if you have such undersea volcanic activity on Europa. It's amazing that extreme gravity can be a source of energy that can potentially support life (in place of light and radiation). I also love his Goldie Locks analogy - i.e. this porridge is too hot (close to the sun) to support life and this porridge is too cold (far away from the sun) to support life, etc.
This made me think: Suppose there are macrobiotic species, animals, things with eyes and a brain, that live on Europa. Or probably more correctly inside Europa, in that ocean between it's surface ice and whatever is the core of the planet (I don't assume it's 100% an ice-covered water ball). What would the ice sheet look like when you looked up to where we would normally see sky? Or would it be so dark on the inside, so little light if any that would penetrate deep enough, that you couldn't see a thing? Do you think the interior oceans of Europa get any light at all? Would a macrobiotic animal even evolve to have eyes in such conditions? I know Earth has fish with eyes that live at depths that are so far down light doesn't reach, but perhaps a Europan fish wouldn't. It could be even darker in the depths of the Europan ocean than the deepest of Earth's oceans.
'All These Worlds Our Yours - Except Europa - Attempt No Landings There.' I know, I know, no black monoliths and Jupiter hasn't been turned into a miniature Sun, but, damn, wasn't Arthur C. Clark a great science fiction writer, scientist, and scholar. Oh, and major props to Neil and Big Think for this vid.
Enceladus is a moon of saturn with a big liquid ocean and gravitational heat as well. Plus we just found some other great signs of life (organic compounds and H2 gas production) there during the Cassini mission.
Can planets which are too close to the star and ,thus too hot for water, be somehow tempered by other natural phenomena to cool it down to be habitable? Say, a dense asteroid belt which would partially reflect sunlight?
what is funny is that azimov wrote a book before he died that was never tied into the robot/foundation series entirely, but was mentioned in a later foundation book at least once, about a world in a brown dwarf system that was orbiting a super massive gas giant that had a livable breathable atmosphere through tidal force. the name of the book is nemesis (it probably also triggered some of the planet 9 style apocalypse conspiracies, because the star was on a collision course with earth in the book, lol, even gave a semi realistic amount of time, well over 1000 years after detection it would impact our system and make a big enough mess to make it unlikely that earth would remain habitable)
A moon naturally gets warmer due to tidal heating and add extra green house gases and a moon could be quite far from goldilock zone and should still thrive in life.
When people talk about the heat death of the universe, does that include these tidal forces? I understand that the last stars will have burned out after a long enough time, but could you still have moons around gas giants that have these tidal forces keeping them warm?
“It’s not a science problem it’s an engineering problem.” What that means is that it’s within the laws of physics and we have the technology to do so, we just haven’t done the math for that specific problem yet. Keep it up, professor! We need ya!
A problem to solve is the ice refreezing above the probe, assuming it will be tethered. Not sure if it is possible to send data wirelessly through kilometers of ice.
Honestly? We need to create an artificial atmosphere in Europa, then make it have some greenhouse effects to warm it up. We will have lots of water before we even know it.
Wouldn't even take all of Earth's efforts. Maybe like 50 billion dollars would do the trick. And that's nothing to the quadrillion dollar global economy
Why would you need to tunnel through the ice if the vents are shooting water vapor into the sky wouldn’t that mean that thats an opening to the sea underneath and a drone could just go in from there?
can a planet be classed as orbiting bodies with a atmosphere compared to a moon that orbits a planet with no atmosphere and planets that orbit a sun since titan and europa are planets orbiting a planet and we do know pluto is a big rock not classed as a planet anymore what you guys think?
Is it possible for other chemicals to be used as an equivalent to DNA in possible alien life? Like, could a different chemical be used as an equivalent to DNA on a different world where DNA itself can't form? In that case, then life could truly be anything.
Absolutely, the next possible chemical is silicon. Carbon is the most chemically active though, so it's significantly more likely than all the other elements.
DNA may not be the only replicator. In fact we modified the foundations of DNA already. Scientist created DNA with 6 base pairs instead of the usual 4 and it worked and replicated just fine. So our usual DNA is just one example of what is possible.
abschussrampe while It would be interesting to see silicon based lifeforms, it's much more likely to a another Carbon one due to the sheer amount of compounds available. I do think, however, it's likely that we see a code completely different from DNA.
abschussrampe silicon is absolutely possible, but the chance is carbon given the abundance of that anf hydrogen. silicon is pretty heavy. it is about as fertile, but carbon is just more likely
Its quite scary that for all we know, we are the only life in the universe which is really depressing that the universe is infinite in all directions and that we seem to be the only life
So you're saying, when all the star in the universe are used up, we can harness the power of black dwarf stars squashing planets and generating heat for trillions of years?
At that point draining black holes of their energy would become more efficient. Those would be viable power sources long after entropy ate all galaxies and all the stars.
WHERE WERE YOU NEIL IN THE 80’s..... because all my earth and sciences biology teachers did was show movie 🍿. That had nothing to do with anything relevant to the subject. We never used the big telescopes 🔭 , the classes were a waste... I wanted so much more ..
Another problem may be that the weight of the ice may be exerting pressure on the water underneath so when the probe or laser or whatever breaks through water may gush out of the hole. Don't know...
If there were intelligent beings on Eurpoa, with a technology about even with outs, would they have any way of knowing there was anything outside their world?
Woooooow. It's already known that light is not needed to sustain life by the discovery of marine life at the deepest parts of the ocean, but is light needed to create life? In the darkest parts of the universe, can there be life created and sustained solely by "alternate" energy sources? If so, is it possible for it to evolve into intelligent life? Such an interesting topic.
They get energy from the gravitational effect of Jupiter and its moons.Europa expands and contracts continually,causing heat.Listen again to the tennis ball analogy.
"Where there is liquid water there is some form of life" Ever wonder why a lot of UFO sightings are reported to be spaceships hovering above a body of water? That's if the sightings are real, of course.
no. There is a time in history when UFO was reported and from there on, people were litteraly "inspired". Also, after the first sighting, one guy refered to his sighting as "saucers" and litterally all of the sightings followed changed the shape for decades from orbs and triangles just to saurcers.
In regard to 'Energy can not be created or destroyed, only changed.' ... What energy is lost during the creation if the Europa heat? I assume the orbit is stable so this gravity energy appears to my laymans mind to be free at first glance.
In Quantum Mechanics, all forces act by using particles to exchange energy. Gravity has the Graviton. They fly from one planet to the other, slam into it and spend their energy. The host planet loses a bit of energy and rotates a little slower and falls a little closer to the sun.
Len Waugh. yes, energy is being leeched from Jupiter and other moons. orbits are relatively stable but not completely stable because this kind of energy exchange takes place. this is similar to tidal forces on earth. moon is leeching energy from Earth's rotation and gradually increasing the orbital radius. It will continue until the moon escapes Earth

Woooooow. It's already known that light is not needed to sustain life by the discovery of marine life at the deepest parts of the ocean, but is light needed to create life? In the darkest parts of the universe, can there be life created and sustained solely by "alternate" energy sources? If so, is it possible for it to evolve into intelligent life? Such an interesting topic.
As far as I'm aware the first lifeforms on earth were chemotrophs.
Just 50 years from now man will wish he hadn't gone ice fishing on Europa! D:
if life IS under the ice surface of Europa, what kind of life do you think it'd be? because it probably doesn't need light (i think).
Probably not sentient.
What about Enceladus?
Jupiter was able to form due to it's orbital path around the sun. So I suppose it IS traceable to some extent.
Yo one question... if Europa is receiving energy... what's losing that energy?
Europa and Jupiter are losing kinetic energy.
They get energy from the gravitational effect of Jupiter and its moons.Europa expands and contracts continually,causing heat.Listen again to the tennis ball analogy.
It's not all gravity-based tides. There is a lot more electricity involved than what's suggested here. Learn.

Ever wonder why a lot of UFO sightings are reported to be spaceships hovering above a body of water?
That's if the sightings are real, of course.
no. There is a time in history when UFO was reported and from there on, people were litteraly "inspired". Also, after the first sighting, one guy refered to his sighting as "saucers" and litterally all of the sightings followed changed the shape for decades from orbs and triangles just to saurcers.
Hey Neil, why are we currently observing changes on all of the planets, not just Earth? Why are the magnetosphere and ionosphere weakening?
I thought that engineering problem is also a science problem but its more hands on.
I searched this after I heard about Shark life on Europa
In regard to 'Energy can not be created or destroyed, only changed.' ... What energy is lost during the creation if the Europa heat? I assume the orbit is stable so this gravity energy appears to my laymans mind to be free at first glance.
In Quantum Mechanics, all forces act by using particles to exchange energy. Gravity has the Graviton. They fly from one planet to the other, slam into it and spend their energy. The host planet loses a bit of energy and rotates a little slower and falls a little closer to the sun.
Len Waugh. yes, energy is being leeched from Jupiter and other moons. orbits are relatively stable but not completely stable because this kind of energy exchange takes place.
this is similar to tidal forces on earth. moon is leeching energy from Earth's rotation and gradually increasing the orbital radius. It will continue until the moon escapes Earth
