How to Find an Exoplanet 

goodbye grandpa,

Hakan Karaağaç He had to climb barefoot through the void just to get to school. Uphill both ways.

calicoixal In 5 feet of snow. With no shoes.

***** and no oxygen.

osmateusz Without a juice box.

Or does it? How.. do you know? [dramatic music playing]

Well, it can't

Tech Viking Or can it.. [dramatic music intensifies]

helloimrobin Probably not. [record scratch]

***** The End... [questionmark]

Religion & Spirituality

I bet the non fiction one is narrated by Morgan Freeman

So brave

Cult classic.

Actually, they're smokin' hot!

hildegain Depends on you point of reference, if you were 8000K then the sun would indeed be pretty cool!

Michylikespie The sun's corona still wouldn't be that cool after all :(

'And stuff'? Seriously!?!

+Leyla Ismayil um no.

LOL

found one .. lol

thanks

+ARMYshawol what is sm?

Lol, I was waiting for this😂😂

Planets are usually found in very different orbit, taking different amounts of time to orbit. The closest large pkanet will have the quickest, most observable impact on the star. If we average the star's wobble from that first plant, we'll notice a secondary, longer wobble, indicatiing a planet in a slower, larger orbit. Repeat until theres no more wobbles and you can identify multiple planets around one star, given their orbits aren't too close.

Aroninia Arkensia I see, thanks for the information!

XClann I was going to say use a Fourier transform of the light variation and each planet will be recognized as its own component in spectral space, but the above explanation is simpler to understand.

Aroninia Arkensia So basically Fourier transforms save the day?

Rand Huso nice!

Dem feels.

It takes more than heart to do astronomy. At least Pluto found out it isn't alone.

What about Eris?

MrSplodgeySplodge WHAAAAAAAAAT?!

Yes, Earth orbit the point called the barycentre.

@@praneelpathak657 I didn't remember making this comment. But though I do remember the facts in this video, I don't remember knowing it was called a barycenter. Though it must have been in some of the textbooks I read. So, think you for your comment

@@WakarimasenKa yes, and don't troll your friends by saying both the Earth and Sun orbits the barycentre of them. Because it's only the Earth which orbits the barycentre of Sun and Earth. The Sun don't orbit the barycentre of Sun and Earth because there are more planets orbitting it. So the Sun orbits the barycentre of Sun and the average combined centre of mass of all the other planets and things that orbit it. By the way did you meant 'thank' instead of 'think' in your last line?

@@praneelpathak657 Yes, I ment to say thank you. Had my keyboard on my phone set to Danish. And since we have more letters, it can be tricky to type with thumbs...

@@WakarimasenKa oh, ok 👍

same

Same lol

Pluto dont need no man

Pluto IS a man ...

So you would be fine with me calling the internet a watermelon. Its just arbitrary semantics.

Complete non-sequitor. There is no reason to call the Internet a watermelon, as it has never been called one and there is no correlating evidence that the two are related. There is plenty of evidence that Pluto is a planet; there's not a scientific consensus, just a majority. And the majority went ahead and changed to 'dwarf planet', and started trying to 're-educate' people. Arguments toward planethood include the fact that Pluto may have multiple moons and has an atmosphere, which is unique among the 'dwarf planets' that NASA classed them into.

You can't argue against a fact. It's like saying 2+2=5

Pluto shares many more traits with large asteroids than with regular planets. It has a very small mass compared to the other debris in its orbit (a few % compared to 99.99999% for regular planets). If we didn't make the definition more strict, we'd have dozens if not hundreds of planets and the word planet would lose its meaning.

Do asteroids have atmosphere? Do they have multiple smaller satellites? There are solid arguments for Pluto being a planet. There will be a close flyby of the PLANET Pluto in a year or so, and we will likely find additional features to support the argument. Also for the record, with its atmosphere Pluto is larger than even the largest 'dwarf planet' that it got shoved in with.

This would be a rather unstable orbit to begin with, so it's unlikely that two objects would stay like that for very long. And technically if two objects of equal mass share an orbit, neither one would meet the definition of being a planet anyway.

SkyrimHod Stop being such a smart-ass :D

SkyrimHod Hmm, regarding having cleared its orbit, I am not sure that would apply. Regarding instability, okay, I'll bite. Why? I can certainly see how it might be an unstable orbit(s), but I don't see why it _must_ be.

CorneliusSneedley What do you mean "not sure"? Unfortunately, that's the definition of the planet - an object massive enough to clear its orbit from space debris and shit like that. So if two such objects revolve on same orbit, they by definition are not planets. Maybe if such objects are ever detected, the definition of a planet will change, but who knows, right?

In our own solar system, yes.

Hugo Rendlesham Okay dude, calm down. Allow me to address a few of the points you seems to of randomly made. "Why are you oppose to people calling out bullshit? Do you like disinformation or something? Do you not think people who spread dribble should be held accountable?" Firstly, those "people" I'm referring to weren't just bashing on others beliefs because of the simple reason you presented. They're actually finding pleasure from hating on the religion purposely. There are ways to try and educate people other than utilizing name calling and derogatory terms to degrade ones belief. Moreover, if you could precisely point out the part in my comment where I concurred to "misinformation" being spread that would be great. Additionally, you think arguments on RU-vid video comment section is a way to resolve this? You have no clue of how to even resolve matters do you? If you want to go and express your opinion and rally, there are forums and organisations you can sign up to. If you really want to do something like your angry comment seems to indicate then join up and actually do something. "We're not talking about harmless opinions here, we're talking about people who deliberately misrepresent facts and even their own religions." Who are you talking about the extremist? Generalizing a group of people based on others actions isn't the most intelligent decision. I am fully aware of the people who manipulate the meaning of religious text in order to achieve their own personal goal. Like when some religious extremist claim that the Bible or God(s) hates LGTB and same sex marriage. Only gullible and ignorant people would actually believe that. Especially when in the Bible loving everyone and not being superficial is greatly perpetuated and emphasized. I openly resent them and show my support by helping organisations to fight against them and any other groups that would oppose others freedom to do as they wish lawfully of course. "Also who is forcing you to read these arguments?" Who's forcing me to read them? Did i mention anyone was? I have the right to read any comment posted on here and, i was simply expressing my thoughts. If you have a problem with people reading comments and expressing their thoughts then you shouldn't even be on the internet. I don't care if they continue with their comments or not, all i said was it isn't doing justice to their cause by doing the same thing that they oppose. Counter-wise, who told you to read my comment and reply? Anyone can use that same argument for virtually anything. You should understand the basis of the argument instead of anticipating my intentions prior to actually understand the comment

Hugo Rendlesham You require a survey to simply anticipate and to be able to tell the difference between actual hate comments and actual legitimate ones? When people say "Christians are stupid," or anything similiar you don't require a survey to understand that. Like I said there's a difference between teaching properly and hating purposely. Ideals will always conflict but they should be debated in a civil and mature manner. You're the one that seems to of rushed into a defensive position of this. The only person who's angry is you. Neither side of the fence? You claimed that I was accepting disinformation. Pretty bold statement when I didn't even say anything like that. That last section of my comment isn't contradictory. You seem to be unable to process what I actually meant.Although, I guess I shouldn't be surprised, you required a survey to be able to comprehend that some people actually purposely hate on religion after all.

Hugo Rendlesham Ahaha simple minded and yes I have had individuals actually confirm my claims that they do actually enjoy bashing on religion because they believe it's only for the intellectually deficient. You're attempting to now segregate the main topic of the argument by saying one aspect of it is childish and people don't read it? Sorry it doesn't work that way. Additionally, if you think you knew what my argument was referring to and you were referring to a different type, then why did you comment? You obviously had nothing better to do and you claimed you were suppose to be "working." I'm not twisting any context, if you believe that then obviously failed to grasp the subject matter. Like I said many times if you could point to the specific parts in my comment where you believe I contradicted myself or said anything that I refute then please go ahead. Otherwise, you're just a random joke attempting to look smart. That last sentence is hilarious, you really do have your fair share of personal issues ahaha.

Abraham rugato I’m not trying to defend Hugo (he sounded rude as hell :u), just explain: Go to a religious channel or video; the same arrogant attitude Atheists/Agnostics have in channels like these will be found there, but reversed: Religious people making fun of people who are not affiliated to their religion. Better yet: Hang out with very religious people. The church I’m forced to assist to makes fun of people who believe in evolution, and I have to dismiss myself at times because my own family makes fun of science itself; it’s pitiful to watch. Most people had TERRIBLE experiences with religious-ness. With time, the mere sound of the words “God”, “faith”, “belief” or “religion” gets on your nerves, and you develop adversion towards all stuff. In my land we have a saying: “si te llevas, aguanta.” If you punch, the other person is in the right to punch back. Religious people are nowhere near being victims, and the people on the Internet use that as an excuse to act like six-year-olds. You can say, “oh, but those people who make fun of science are not ‘real’ Christians/Muslims/X-religion. They’re just a**holes!” We can say the same about Atheists. We can say that those pedantic citizens are the cancer of Atheism, the equivalent to Creationists in Christianity, but there’s no use. I KNOW Atheists/Agnostics are the pseudo-martyrs of turn. We’re drowning on 2-kook-4-skool kids thinking they’re cool and edgy for saying Virgin Mary is a whore. But pointing them out or generalizing won’t make neither the Religious Freaks neither the Pseudo-Intellectual Atheists go away, will it? The point is: Social stupidity doesn’t discriminate religious affiliation. Ask the Middle East.

Mimicke Didn't read through your entire comment but I assume your talking about religious people doing the same thing ? Regardless,my position in the argument is clear. Ultimately, i would like to see a video where neither parties are spamming comments with derogatory terms and hate towards each other. At the end of the day, they are all as bad as each other. You can't fight fire with fire. Ignorance is the root of all these silly conflicts. In time,however, and hopefully things will change and they will come to a understanding that they both have different perspectives. That's all i have to say about the subject matter.

Pluto the Roman equivalent of Hades. Not really sure if I want that.

And he'll give you the power to use the words "one" and "once" correctly.

TheGERO418 Oops, fixed. I'm terrible at proof reading.

Pluto is love, Pluto is life...

How's an animated dog going to punish me?

Why?

KaosFireMaker Because that's what we were taught in preschool and it's nostalgic and funny.

Cheppa I wouldn't want to still believe that the Earth is in the center of the universe because that was what people were thought before.

Syeal7 Well I hope you don't because that would be stupid.

Cheppa hehe, well atleast I think you've got the point. I guess that's the important part.

Nope

***** But it's the most concise and correct explaination. All the planets and the sun rotate around the over all center of gravity, which is inside of the sun only because it's so big.

TheDahaka1 Yeah, the Sun is somewhere around 99% of the entire mass of the solar system. I suppose we do rotate around the Sun, even though the Sun rotates too, but since the center of mass is so close to the Sun's center of mass, it's easy to take its rotation as just a simple revolution. Regardless, our orbit is around the sun's orbit so semantically we undeniably go around the Sun.

We orbit around each other.

well in our solar system sun is like %98 or 99 percent of mass, this effect is pretty much minor.. so we do orbit the sun

Hakan Karaağaç Ugh why are the hot ones always gay

Jacksi :3 I am usually a fan of bad puns, but this... This is just too much

He hasn't yet bit we all know he gay. It's quite obvious

Kim Jong Un well im not gay but if you say so kim

Connor Spencer Yeah, let's travel to a planet that we can't even directly see and hope there's something worthwhile on it after traveling for a zillion years and spending a trillion dollars to get there. Scientists can't even get to the majority of the ocean floor on earth and you're fantasizing about other planets. Get a life on earth, buddy.

TheGERO418 Potential goals? HAH Here's a goal... figure out how to have a good life on earth. I bet you work at a crappy job making a crappy salary and barely getting by and you're worried about space travel. LOL.

Hakan Karaağaç Looking at lights in the sky that wobble is not science and it's not practical. They still have not confirmed the wobble is caused by planets. It's all a hypothesis.

hildegain Those things you list benefit many people on earth. Exoplanet hunting is just pure waste of time and a waste to public resources. Those telescopes should be focused on asteroids and yet many asteroids have slammed the planet in recent years surprising the so-called genius scientists. They didn't even see them coming. It's like driving your car down the highway and focused on the moon in the sky instead of the headlights travelling at 65 MPH coming straight at you. Supporters of this so-called science are dumb liberal Obamatards.

***** I can't tell if your a troll or excessively misinformed.

well for today the only way to "look" at othe rplanets surface is, if they are close, telscopes, if they are far, probes with cameras, exo-planets, no way as for now, but we can still detect its mass, its distance to its parental star therefore what kind of elements it might consist of.

Not really. It's just you're too lazy to research the science yourself.

Haha. I'm starting my final year of a Mathematical Physics degree next year. You're right. I'm clearly too lazy to do science myself. As some examples of some of the recent videos I was talking about: Immovable Object vs. Unstoppable Force. Nonsensical Question Bollocks. How Far Can Legolas See? Pop-Culture Bollocks. Is the Universe Entirely Mathematical? Philosophical, Non-Scientific Bollocks. As opposed to the pretty high quality and interesting videos that were posted here when I first subscribed to this channel a few years ago. Have a nice day friend. You should lay off those unjustified assumptions. (:

***** So why you rely on RU-vid videos to do your research then? Are you sure didn't make all of that up? For someone who does that. You don't seem act very intelligent on the internet. lol. You're just lazy my friend. Knowing you probably used videos on youtube to do most of your research by the way you're telling me. Libarary books from famous lecturers pfft you needs that. When I can watch video of MinutePhysics? *sarcasm*

Marvelrocks "rely on RU-vid videos to do your research then" I never said that. RU-vid videos can be entertaining. I don't do astrophysics, nor do I do any experimental work. It's interesting to see little methods like this. I was first introduced to the Casimir effect from a RU-vid video for example. Have a nice day.

***** Then apologises for my arrogance towards you. Have a nice day and good luck with that degree.

Exo MAMA lols. ㅋㅋㅋ

becouse wubbles arent one directional

As the planet moves around, the center of gravity changes. Imagine a table with one leg in the center. You want the center of gravity to be in the middle, so you put weight on opposite sides. The wobble effect on the star is a similar concept. The center of mass can't move, but the star and planet does.

DJRAMO4LYF thanks that help alot :-)

we can only find large and massive exo planets, with the finding of pluto its not a easy - hard debate , its an effective- ineffective debate

Finding Pluto had nothing to do with transits and if it had, there are plenty of stars it could have passed in front of. Planets within our own solar system are much easier to find by the light they reflect from the sun rather than the light they block when transiting in front of something else. What made Pluto so hard to find was that it's so far from the sun and so small that it doesn't reflect much light. Its orbit is also tilted at a very different angle than any of the planets, so most astronomers who were looking for a new planet would have been looking in completely the wrong direction to find Pluto.
