!!!Alpha Centauri!!! (The Suns Neighbour)

[ShadowHawkblack]

I love this show!

[Socoolscienceshow]

@ShadowHawkblack awesome :D

[davydekemp]

So the size of a star determens what happens to it when it dies?

[Socoolscienceshow]

@davydekemp For the most part yes, the bigger a star is the more fuel it will have and thus is why a bigger star can explode into a super nova. The less fuel you have the less power you will have and thus the chances of it exploding are extreamly low. How-ever theres always going to that one-two exception to the rule.

[tfan0]

Hey do you know the star called VY Canis Majoris? that star is super super super super huge then our sun!! it's the size of our solar system! Like let's say a picture of VY canis majoris comparison with the sun. the sun will be the tiniest dot!

[Socoolscienceshow]

@tfan0 Yup VY CMa is the largest star we know of currently and its known as a hypergiant star. If you place that star at the center of our solar system, it would stretch out to about as far as Saturn, which is about 9 AUs (astrononical units). If you placed one side of that star where our sun is, that star would stretch out to about as far as Uranus. So its just slightly smaller then our solar system. Uranus is 2 times as far from the sun then Saturn :D Everything in space is huge and far apart.

[moontalon22]

@Socoolscienceshow VY ca also is exactly 2.800,000,100 km in diameter. but being a big star its also a very old one, and will explode in a Hypernova? correct me if im wrong.

[Socoolscienceshow]

@moontalon22 congraduationals thats very close, its diamter is 2,842,359,530kms. Im not sure how old the star is, but size alone doesnt always mean a star is old. When it dies off theres probably 2 things that will happen. It will go off in a hypernova and then form a black hole :)

[moontalon22]

@Socoolscienceshow

Oh ok cool. I think the number of the size varys alot of vy ca but mostly 2.800,000,000 yours must be exact though

[Socoolscienceshow]

@moontalon22 yup thats the exact distance, if you calculate out all the AUs of the diamter of that star :)

"when i grow up, i want to be Jim Carrey"

[Socoolscienceshow]

@gloup81 at first i thought you were gunna say "when I grow up I wanna be just like you" but being jim carrey is awesome too :D

[iank4758]

This only tells us witch star is in front of the other not the distance?

[Socoolscienceshow]

@iank4758 what are you talkinga bout, if a star is infront of another star that means its closer then then the one behind it

[iank4758]

@iank4758 What am i talking about you ask lol. You have almost said the same thing i have just said....i know what this guy is saying, ok lets make this simple, take the closes star to us its 4.3 light years away! How are we arriving at this distance is what i would like to know, also would we use the same method to measure the distance of a star that is lets say 14 billion light years away? the edge of the known universe or there about.

[Socoolscienceshow]

@iank4758 Astronamers use something thats called redshift for extream distances measurement. Stars that are closer to eath tend to appear blue on a spectrum and stars that are further away from us tend to appear red on a spectrum. What they do is measure the color of the closest star to us on a spectrum. Then compare that color up aginst other colors coming from stars. We know the distance from earth to the nearest star so they look a the units of color change and then do the math :)

[iank4758]

@Socoolscienceshow Thanks for that info, Now i understand a little better. :)

[Socoolscienceshow]

@iank4758 your welcome :)

[paideguinha]

How about a star size comparison?

[Socoolscienceshow]

@paideguinha That was different sci file, did you see the sci file on "exo-planets" I do a comparison of our sun to the another star :D I dont know i'll have to check into it and see if i can do a star sized comparison that everyone can do :D

[sickwititnan0]

we will travel to alpha centauri around the year 2030.. when the sun is closest to it..

[Socoolscienceshow]

@sickwititnan0 Alpha Centauri is extreamly far away it would take 4.3 light years to get to the closet star in the Alpha Centuri System. That would be awesome though, to travel to another star and stay to orbit :D it will happen some day but not by 2030 probably more like 2330 depending on what space travel technology we human create :)

[AlexanderSchryvers]

@Socoolscienceshow First of all, the Suns neighbour is not alpha centauri but Proxima Centauri. Alpha is the brightest star in the constellation of Centaur.

And 'we' won't reach proxima in 2030, not even in 2330, not even in 8000. Knowing that the human race is eradicated within 8000 years from now, we'll never reach proxima centauri. Although, not a space shuttle with men aboard. It can reach a speed of 27 000 km per hour. That means it needs 136 000 years to reach Proxima.

[Socoolscienceshow]

@AlexanderSchryvers True that the human race will go extince in 125,000 years but i think in that amount of time we will have created some sort of tech to be able to travel around our galaxy or possibly even outside of our galaxy or more on the hopeful list but most likely not, even travel to other universes.

[abradras]

@Socoolscienceshow at 2330 we will fight each other witch sticks and rocks ^^

[Socoolscienceshow]

@abradras you think so....

[honda5ray]

I want your Husqvarna hat.

[Socoolscienceshow]

@honda5ray I may ocction it off with a few other show props. But the jacket wont get accutioned off untill im finished making sci files :D

[bigv111111]

lol

[Socoolscienceshow]

@bigv111111 =^D

[turbocanuk]

THIS GUY IS STOKED

[Socoolscienceshow]

@turbocanuk my fire is stocked

[unobombers]

awesome video! :)))) X5 :D

[Socoolscienceshow]

Thanks a bunch, Im glad to hear that cuz this shoot wasnt finished till 1:40am. Thats when the cops showed up & told us to shut it down. Apparently us filming to entertain the fellow youtubers, is a major crime. After all there couldnt posibly be any other acttual crime that is much worse then us filming late into the night, because we want to make sure that eveyrone who watches the science files gets the professionalisum they deserve. We are so BAAAAAAAAAAD!! LOL

[NoHopeForGays]

lol wow you stayed up till 1:40 doing this D:

[Socoolscienceshow]

Usally when we do the night shoots its after the sun goes down. We didnt start this untill 10:00pm. Each shoot usually takes about 3-4 hours, because the show is not written but improved. Before the camera even starts recording, several improved sessions are done untill the 3 of us who put this show together are laughing histaricly. Count in the time, for settings up the camera, tripod, monitor, hooking the camera to the monitor, lights, electrical cords, mistakes & you get 4 hours

[NoHopeForGays]

so much work lol good job

[Socoolscienceshow]

Theres that old saying that goes "do what you love & you never work a day in your life" LOL

[british123able]

@Socoolscienceshow what telescope do you recommend? i have $850 dollers to play with

[8592666]

awesome, for some reason you remind me of shaggy from scooby-doo lol ^_^

[Socoolscienceshow]

LOL

[nathanh180]

I love learning <3 lol

[Socoolscienceshow]

I think if more teachers would make thier lessens more entertaining (they dont have to be rock stars or hollywood actors) then I think people would enjoy learning more. =^D

[FramedThief]

Very nice. I already knew all the information from taking Astronomy, but it's very well planned out. :]

[Socoolscienceshow]

Im glad you enjoied the lay out of this science file & Im definely glad you know your astronomy. Although there are otheres who dont know. Im sure others, just like those who have messaged me before, are happy to be the only who know the answer to their science teachers question because of something they learned from the "So Cool Science Files."

[HipHopJun]

Black holes are scary..... i always thought you could travel through them. But the gravity is so powerful you would be crushed to death, or something like that.

[Socoolscienceshow]

Well, youd be ripped apart by tidal forces caused by its super-strong gravity. Basically, if you jumped in feet-first, (dont try this at home XD) your feet and legs would be sucked in faster than your head and upper body (or vice versa if you dived in head-first). So your body would be stretched out lengthways until you snapped like a rubber band. Take a space ship its a safer way to travel.

[Bile420420]

Lolol, this made me giggle :D

[Socoolscienceshow]

LOL

[jungleman68]

spaghettification

[Socoolscienceshow]

Alright you know your astrophysics! spaghettification for those who dont know is the stretching of objects into long thin shapes, like spaghetti, in a very strong gravitational field, and is caused by extreme tidal forces. In this case, near black holes. Kool!
