ScienceCasts: Re-thinking an Alien World

[@patrickdaly1088]

Key details missed in this video: planets this close to their stars are one face (tidally locked, similar to the moon-->earth tidal lock) almost always. it has to do with the gravitational forces and the proximity of the bodies. Tidally locked planets have their atmospheres frozen on the backside. while the sunside might be 3200F, the backside is only 10 kelvin. all of the water could easily exist as a gigantic icecap on the "dark side" of the planet.

[@kyleklassen3660]

Just because a planet is similar in size to Earth does not mean the planet is like Earth. YOU DON'T SAY!! Wow thanks NASA

[@ToddHowardWithAGun]

It is interesting that Cancri e has supercritical fluids. The main reason why exobiologists speculate that water is necessary for life is because fluidity is necessary for unusual combinations of molecules which eventually lead to life. Since this planet is actually fluid and not solid, the potential for complex molecular structures on the planet's surface is much higher.

[@RRRaiken]

alright first of all what you said there made absolutely no sense but i'm not gonna waste anymore time on you. let's just say that the society need people like you. people like you can constantly give confidence boosts to others. you're an important piece of brick at the bottom. not that we really need one, but it's quite nice to have one.

[@danielbluesmoke]

Don't hate them! That is a SEO tactics used to attract more views! This is a common web practice! If you were them, you would do the same... The most important thing in an article, video or picture is the title. It must "wow" you, to make you click through! And also, "alien" has different meanings, like: strange, out of our normal experience, something we're not used to.

[@lEtudel]

Thank you so much for great video and English subtitle~

[@iiNadeTech]

@fronabadger I don't know how we arrived on this subject. They aren't talking about alien life. They use the term alien to refer to something not of a specific country, planet, solar system, universe, or multiverse. In essence, it is anything foreign. I believe you have misunderstood.

[@TadaGanIarracht]

haha thank you for the polite response but I was trying to be sarcastic/funny. But hey it's cool of you to go through the effort to tell me. There's Farenheit, Celsius, Centigrade and Kelvin! Plus probably more that I don't know of!

[@z4k4z]

@Caprican28 I think the term "alien" here means "not of our normal experience" or "not of our solar system". Nothing to do with alien life :)

[@aaronguitarguy]

Your journey begins here!

[@kaibowman2305]

superfluid is also the messerschmit me-163 and me-263's propulsion

[@seapeddler]

Water may be critical for most types of life, but the entities that live in crystals require minimal moisture, if any. Unlike the 'water -cooled' processors for sale, the crystal skulls were used to communicate over vast distances, psychically, without heating-up. As usual, the correct answer is wrapped up in some career oriented get rich scheme.

[@DarkSigner7]

Is a degree value used in the English metric system, which measures degrees differently from celcius. Is like inches instead of centimeters, lbs instead of Kg.

[@Carlito0220]

One year .. in half a day that's kind of crazy

[@InscrutableOutlander]

we're not looking at this stuff for no reason. There is a reason, it is just one that we people that are not involved with the research no absolutely nothing about, which of course leaves us to only speculate as to why.

[@Sadderdaze_d]

This planet is the one that is covered by the crust made of pure diamond

[@AnotherPostcard]

@jrbelmont It is kinda hard to search for something you know next to nothing about. All we know about in this regard is water reliant life. Until we find more information about other kinds of life, water is what we'll be searching for.

[@brooklyna007]

If you mean we could use Lagrange points as ports, that's true. They would probably be used as a place to dock scientific instruments like an interstellar version of the Hubble telescope Sounds like you like technological singularity theories? I do too. But it's good to balance respect for the incomprehensibility of exponential growth with understanding how far computers have to advance before matching the general power of human intelligence I think humans will be the ones who solve this problem

[@Dyslexic-Artist-Theory-on-Time]

Neat vid! This is an invitation to see an artist theory on the physics of light and time! This theory is based on two postulates 1. The first is that the quantum wave particle function Ψ represents the forward passage of time ∆E ∆t ≥ h/2π itself photon by photon. 2. The second is that Heisenberg’s Uncertainty Principle ∆×∆p×≥h/4π that is formed by the wave function is the same uncertainty we have with any future event.

@JimmMyHero Again: No prejudice.

[@kvmairforce]

I'm a big advocate of self-learning and motivation, but there are limits to what you can teach yourself effectively, hence why every modern nation has a school system. I agree a "degree" by itself doesn't make you wise or smart. If you ever associated with highly educated people vs people who didn't even graduate from high-school, there is a huge difference in thought-process usually. Of course there are always going to be outliers.

[@AnotherPostcard]

Uhhh wow, dude. I think I've been misunderstood here. I was saying we know next to nothing about anything OTHER than carbon based life. And I never said anything about the probability of finding other carbon based life out there. For the record I agree with you on everything you said. I hold out the hope that we will find extra terrestrial life out there just like you do and even go a step further. Perhaps we'll even find non-carbon based life someday, we just don't know what it looks like yet.

[@jonas6259]

Fine, you have a job as a teenager at a fast food restaurant. I am going to school, learning for a better life. And I've always thought canadians are polite ...

[@DaedalusTV]

Have you ever heard of the Hubble space-telescope? It can explore vast distances with high detail pictures thanks to our good friend called "light".

[@Dyslexic-Artist-Theory-on-Time]

Good video! This is an invitation to see an artist theory on the physics of light and time! Based on just one equation (E= ˠ M˳C²) ∞ the Lorentz contraction of space and time is between the energy and mass. The greater the energy the greater the contraction of space and the slower time will run. Mass will increase relative to this and each ref-frame can be seen as a vortex in space formed by the rate that time flows. The brackets represent the boundary condition of the ref-frame within infinity

[@ThisBitchThrasher]

Ive noticed that nearly all the planets they have found are REALLY close an HUGE....im thinking is there something wrong or maybe flawed in the way they find /estimate distance and size?

[@kvmairforce]

Not sure if you are being serious, but it has taken nearly 40 years for Voyager 1 to reach the outer solar system and that isn't even 0.00001% the distance light can travel in a year. Even with a predictable evolution of powerful Ion engines, it is extremely unlikely that we will get anywhere fast. To reach Proxima Centauri we are looking at about a 20,000 year journey if a country did decide to spend trillions. And NPP isn't even a possibility in the next 200 years.

[@cruxader27]

40 light years from earth?? i don't think we can ever explore other planets outside the solar system. Even the Voyager mission which was launched during the 70's has just left solar system for more than a couple of decades. Speaking of its distance from the sun i can say it of not more than a light day away.

[@ZeushyTV]

Dont wna burst your bubble but isnt it a bit too obvious? With how much close it is to its star I think its really given that its temperature is too high to compare it to earth-like conditions?

[@mystic8580]

Getting a degree is not the pinnacle of learning and understanding. Thats just what society tells you....

[@z4k4z]

When it comes to interpreting exoplanet data it seems we're a little to sure of ourselves. Let's face it: at these distances, any theorising about planet make-up has to be taken with a truck load of salt.

[@jonas6259]

It is from Mass Effect, the computergames form Bioware.

[@bimmjim]

It must have a ceramic crust with an ocean of molten metal under that. I can't see how there could be any solid core at those temperatures. Could the core be an Amalgam like tooth fillings? . There would be out gassing. The surface gravity would be similar to earth's but the pressures in a metal ocean would be . . . very high. .. . Correct me.

[@Sakkehattu]

Lets say you´re watching at two (2) objects, one is as large as the Eiffel tower, and one is the size of a pingpong ball, you are exactly 500meters away from both of them, which do you spot faster ?

[@cruxader27]

@1AnimalMother1 well thats a good news but i hope they can reach near speed of light as much as possible, even the nearest star in the sun is about 4 light years away..

[@blindandwatching]

How does it compare to the planet Venus?

[@bimmjim]

+blindandwatching Venus could have mountains capped with Aluminum snow. There was some evidence of that.

[@willlu3220]

SOUND FUCKING BADASS MAN.

[@anon12377]

"wetter and weirder than anyone imagined" LOL..... that's so bad out of context.

[@jeanclaudejunior]

Maybe it's a medieval world with dragons, goblins, dwarves, elves and everything from myths and fiction

[@milky_wayan]

Maybe NASA should get a bigger budget first.

[@chairmanofrussia]

i ask this because this reminds me of that.

[@unaidedj10]

interesting, and a cool but sad thing to know is that we are better equiped to go to mars right no than when we went to the moon. it's just that back than we had to compete with soviets but know we are in a middle ground. not needing to prove anything because we already have but not advanced enough that we can do it for our own purposes like exploration. i think that within 20 years when we have solved the larger problems people will want to look to the horizon for their calling.

[@DarkSigner7]

I thought they would speak of Mass Effect 3.

[@jonas6259]

We have to explore the Mars. So we can find the prothean ruin. So we can build Mass Effect ships. So NASA: Just do it. ;)

[@socerstr21]

why do scientists assume the conditions for other alien life must be the same conditions we live under? I mean, why can't there be aliens living in extremes we couldn't hope to survive, but find the conditions normal because of their evolution. Astronomers follow the Darwinism beliefs, right?

[@jonas6259]

Oh yes, I am soooo addected.

[@1950Viper]

40 lightyears away over a million years away. One way....

[@Salty.Peasants]

exactly my point. I knew this before they even found those bacterial organisms at the bottom of the ocean breathing arsenic and having a totally different biology than any known organism on earth! So why not other species on other planets that can do the same or even breath in methane? "Science fiction has as great a role in opening one's mind to the imagination then science fact!"

[@DarkSigner7]

You're welcome. Those scientist geeks doesn't seem to openly answer peoples' questions and thus it mocks me. What's the point of make public something they saw in outer space when they won't bother to clarify things we don't rightly understand.

[@Caprican28]

I hate how NASA toss the word "alien" around. Why can't they use the term "habitable" instead? Everyone knows unless there is a MAJOR news report, there are no aliens so it just sounds silly and confusing.

[@VerumAdNauseam]

Best way to make space livable is to change ourselves, our bodies, to be better able to live in space. Genetic enhancements and cybernetics.

[@FLPhotoCatcher]

If I was born on that planet, I would be 18,010 years old.

[@tanuki460]

Don't find it.If we use Mass Relay.We will found a war(first contact war ) and We will end when reaper come.

[@QuadrupleXrainbow]

[@luiscalderon3135]

Esto debería estar también en español..........

[@aimingalex]

NASA should seriously consider putting more effort in the exploration of Mars, and possible manned landing. Read Robert Zubrin. Just sayin..

Alien = not from Earth. There's no prejudice on it.

[@charlesverg2184]

This video is so random, whats next? Giant asteroid 6654 LY from earth :0

[@korikakumei]

kind of like james cameron's AVATAR??

[@brooklyna007]

I think NASA is working on a version of the Interplanetary Transport Network for intergalactic space that uses Lagrange points between stars and what not. But it's all gong to stay on paper for a while since NASA's budget is a mere .5% of the GDP now. If we move it up to 1% we could get some test runs going. But right now we barely have enough money for mars, ISS and EM spectrum space telescopes. =/

[@austinpigg5759]

I'm scared for November. Can som1 tell me something about it?? Please

[@jonas6259]

And how could you know that i play video games all night and day?

[@jmoneymaker96]

18 hours for one orbit!

[@hlnbee]

very interesting

[@IGMSItoX]

Or New horizons may discover mass relay behind the pluto in 2015 lol

[@romeo6117]

damn, I'm learning about planets and shit

[@borisboy1020]

Right

[@911review]

Pablo is 8 years old.... Hope you feel real superior now

[@kvmairforce]

As much I like Wikipedia, information on there isn't totally complete or always accurate. Not sure of your age. If you are really interested space travel, I would suggest majoring in astronomy or engineering of rockets in college. Both of them will include physics and give you a good understanding of space travel in reality and not theory. Self-learning is a useful tool, but getting a degree from a reputable college in an area of expertise is still the pinnacle of learning and understanding.

[@primemagi]

If you are serious about space you and NASA better rethink about lots of your facts. past 40 years I haven’t seen any sign.

[@borisboy1020]

Yah

[@AnotherPostcard]

So this planet is like a turkey being baked in an oven, with all of it's juices spilling out of its pores. Interesting.

[@Salty.Peasants]

OK fair enough.

[@JRP.31]

I would hate to live on 55 cancri e, could you imagine being stuck on a plane ride half way around the that planet with a baby! haha...

[@chairmanofrussia]

I believe in god and science. I have a sort of "customized belief" that includes god, science, and reincarnation. I have a question. How is our conscience made? I mean. right now all it seems like to me is that you put a bunch of molecules and atoms together in a certain way and it makes a human? So when we die do our atoms separate and go back into the cycle of nature? how do I know I won't end up being a blade of grass when my body fertilizes the ground? :o do we reincarnate this way?

[@gladmans]

55 cancri e, 55 cancri e, 55 cancri e, 55 cancri e, 55 cancri e

[@ThePjChavezChannel]

OK. Game time over :P

[@VictorKidd53]

PANDORA!

[@mystic8580]

I can agree with this comment.

[@js7161]

alien is something from somewere else, like a mexican

[@Salty.Peasants]

you and everybody else that thumbed you up are very stubborn and small minded people to think we are the only carbon based life is just silly and immature! Carbon is one of the most abundant elements in the universe. Look at all the planets were finding so far and put two and two together......you get my point.

[@throwaway2011]

how did they not know that if something is similar in size than its not the same, they are idiots. its like a tennis ball and a golf ball
