Q and BA Episode 2: Journey to the Center of the Sun

[sethmusic]

check out the ghost at 1:38 !! jk

[yoctomx]

ok, so you say the Sun is not avarage, but then you fail to tell us why is it so?

[jqs1943]

Earth's sun is a planet's core that's evolving. It consists of gigantic spherical magnets that are inundated by a sea of ions in a plasmatic state. It will go through some osmotic metamorphic changes before it accelerates its architectural evolution and becomes a world as we know them.

When brown spots start to appear on its surface its because it has began to develop a skin. The skin will be made up of magnetite which will serve as a medium to support the substratum where the crust will rest.

[haloKINGSstudios]

1:38 a ghost orb thing slides past the screen from the top left :O... or its just some dust ^_^

[LonesomeTroubadour]

It's the mini marshmallow of science!

[thedarkelf05]

I'm an American and that eye roll was hilarious! I'm also a little sad that most Americans watching would probably need that conversion :P

[TavPanoramic]

Hi Gitars5

it is because atoms are made up of protons and neutrons, which are of about the same mass, as well as electron(s)with negligible mass. 1 Hydrogen atom has 1proton & no neutron, while a Helium atom has 2protons+2neutrons, so hope u see why the mass of 1 He atom = 4 x H atom.

[Gitars5]

helium is number 2 in the perodic table, then you need 2 hydrogen atoms to create a helium atom, because hydrogen is number 1 and have one proton in its nucleus, so how can you need 4 hydrogen atoms to create a helium atom???? (confused) (sorry if its some typing mistakes i wrote this in a hurry)

[GaseousAnomaly001]

There are a total of 4 protons and 4 electrons in the ingredients to fuse a helium atom. There's an interesting property of protons and electrons, where they can combine (i know, it's a bit more complicated than that, but for the sake of simplicity...) to form a neutron. So if you add all 4 protons together in the nucleus, and then add to 2 of them an electron each, you end up with a nucleus of 2 protons, 2 neutrons, surrounded by the remaining 2 electrons. Hope this helped!

[Maxdwolf]

Minor technical point. The 150 grams of sun stuff at the center do not "weigh" anything. :)

[AvidElephant]

hahaha wow

[Kamidake83]

WooT mini marshmallow of science!

[f1rz3nz3r0]

It's not like the US is alone in the refusal to accept SI units. With Liberia and Burma they are in good company apparently.

[soulinite]

GO FUSION!

[nannynicklife]

give me that marshmello, i'm hungry!...my friend u r a lot of fun. too bad i didnt have u as my teacher in high school. i couldve actually learned something. unlike most people u r not boring. u made this fun.

[jenchillada]

I like it.. I want it. The sun rules and it doesn't cost a thing. These pesky capitalists who send me paper shit every month where they overcharge me for electricity should be sqashed like a marshmallow.. and then I could eat them with grahm crackers and hershey bars and be glad for them. But right now i hate them. So can you help the world have less money to pay and more marshmallows to eat?

[BanjoNaps]

overcharge? Make your own then.

[ZeromusIV]

suopdragon42 makes you look bad plait you should look at his videos and comment back

[soupdragon42]

The Sun is NOT made up of hot gas! Plasma is a distinct state of matter, wherein electromgnetism dominates. The math for hot gases, therefore, is not appropriate. This is why conventional astronomy is unable to account for most solar phenomena, not least the the fact that the corona is much hotter than the surface!

[NAMLegolas]

Holy poop! I hope the water in my toilet will never be converted into energy while I'm around! D:

I did hear that if you add all the energy received from the Sun to Earth and blast it in one single explosion it would crack the Earth on its half :/

[rationalway]

Four protons fused together would normally form a berilium isotope nucleus, because the atomic number of beryllium is 4 and the atomic number of helium is 2, but through a process known as gamma decay some protons turn into neutrons.

Those 2 protons and 2 neutrons fused together weigh less than the total mass of 2 free neutrons and 2 free protons combined. That mass difference is the amount of mass that's coverted to energy.

[manucapo]

you mean beta+ decay

[rationalway]

Yeah.

[FelleAndersson]

You said 6000 DEGREES Kelvin :P That's wrong x) Although, cool video and it's awesome ;) But you don't say degrees Kelvin, you just say Kelvin :)

[weedbix]

He IS talking to the layman.

[Salladsdressing]

I could listen to you FOREVER! =D  You rock!

[CivilHuman]

Thanks allot very good video. much appreciated.

[jakobole]

Great lil' lecture - thanx!

[Mattnesss]

"For the American listeners out there it's about 5 ounces, one third of a pound. For the rest of the world listening - it's a hundred and fifty grams."

Did I hear a hint of irony in your voice just there? :P

[Retardretroguy]

Funny that he felt the need to convert it to American listeners, since USA was among the first countries that took the metric system as a stantard.

[ctastrophe]

As a life-long resident of the USA, by way of California, I can safely say that I have seen ONE government-constructed road sign that had distance in Kilometers, though luckily it had miles too or I wouldn't have had a clue how far it was to my destination (until I saw the next sign I suppose). Not sure which USA you're talking about, but I'm pretty sure it's not the United States of America...

[drunkasssteve]

Rewatching all your wonderful videos on my day off (or as others will say, Thanksgiving) I just noticed that you were sporting the Bad Medicine book instead of yours. Very cool!!!

[Clausfarre]

Oh, I see I am not the only one making the Sagan connection... Phil, you rock.

[Salladsdressing]

You are good at explaining things in a way that EVERYONE can understand! Ever thought about doing a documentary? Going in Carl Sagans footsteps? You really are doing a GREAT job man!

[pjalne]

Wait, a helium atom isn't four hydrogen atoms, is it? Isn't it two hydrogen atoms and two neutrons?

[TheBadAstronomer]

Pjalne, that's correct. That's why I said "it's more complicated than this" in the video. :-) There are several steps involved in getting the hydrogen atoms to make a helium atom. You can look for it on Google; there are lots of sites explaining it.

[theleeburton]

Then why is it hotter in the corona than the center, if the reactions happen there would not the nucleus be the hottest...could we have it wrong, yes the maths will work and nuclear is powerful we formulated both, but could the sun be fueled by some outside influence..like maybe an electric universe - just curious thank you for your time

[faolitaruna]

No. You do it wrong.

[ticijev]

I almost cried :P

thnx for posting :)

cheers

[Bakamaru8]

awesome video man.

[djserrin]

I love you... but not like that.

[rbowden123]

your awesome! so smart and its good that your providing answers for people who are interested, good work.

[flaxion10]

Ya, you should have a TV show. Actually you should be a professor. Thanks!

[tonyinbjg]

Wonderful, thank you.

[dooomgeist]

wow, soooo nerdy.  You are my hero.

[ddemartin]

Great show, Phil!

[ferncansino]

haven't you heard?

recycling is Bullshit!™

[TheBadAstronomer]

It's actually my home office, but it doubles as a guest room. But of course you're correct anyway. :-)

[IheartEdWitten]

These episodes are filmed in the boudoir, why? Because Astronomers get all the chicks!

[TheBadAstronomer]

Send me email at thebadastronomer "at" gmail "dot" com! That's where I'm collecting all the questions.

[chibraxial]

@TheBadAstronomer

""How dense is the center of the Sun?" Turns out, pretty frakking dense."

Frakking? ... Do I smell some battlestar galactica over there? :)

[conoba]

I would like to see more of the Q&BA episodes. A more extended version on TV is certainly something I would watch.

You remind me a lot of the (astro)physics professor Harald Lesch who has a show on german TV.

[bankeh]

Should we just ask questions in you tube or sent to an email, if so.... what email :-p

[singedrac]

hot :)

[kwakhed23]

great presentation. i'd love to see you and neil degrasse tyson take turns explaining stuff.

average? definitely not. with the advent of telescopes powerful enough to get a better idea of the number of smaller stars, we know our sun is in the top 4% of stars in our galaxy in terms of mass. but you already knew that. :-)

[Icabobster]

i agree with everyone else. TV Show.

"Trash bin. Trash bin."

"...dwarfed, Dwarfed!"

hahahaha

[darkpheonix262]

you need to get with the discovery channel to have your own show

[svevendeord]

Excellent!

[riedsa]

Phil.. you are the best. Time for your own TV show.
