NOVA (PBS) - Hunting the Edge of Space - Part 1 (2010)

[stikowsky]

I say the USA is the first who saw the edge so it's OUR TERRITORY

[alexamada]

@stikowsky Actually, I think the Soviet Union may have been the 1st ones.... We can still kick their asses and take it, though.

[RyanDemaree]

I highly doubt Galileo saw jupiter in even that much detail

I own a moder 50mm refractor and it shows nowhere near that much detail

[Banged147Chicks]

I cannot stand these religious freaks who come on here saying this is false information. As time progresses, the more these lunatics look more like... well... lunatics. There is no room for "god" in the future. Well, not the god that the bible teaches... and I purposely did not capitalize these key words.

[sjohnson12]

This is true to an extent. You would have to have that telescope move faster away from the earth than the light you would be trying to capture. Pretty amazing stuff, eh?

[supahcanfly]

I'm in like 8th grade but I heard that we have the ability to see the earth from millions years ago. Since light takes time to travel... we see planets far away from millions of years ago... we have to get a big telescope far away and take pictures of here that way we could see ourselves from like millions of B.C.

[avpkid345]

@supahcanfly Yeah, that's sort of true. We can't see our own planet from billions of years ago, but we can see different galaxies from billions of years ago.

[jorgepeterbarton]

@supahcanfly the problem, is you can't go faster than light. so you send a telescope out its will get there millions of years later, look back and it will be after now because of the time it took, then take millions of years beaming back to the signal, so unless we find a wormhole or something its not really possible. you'd wait a million years to get a picture half a million years after the point you'd started.

[bbizzy89]

@jorgepeterbarton True or false, science is always changing and discovering new characteristics of physics and whatnot? (true imo) with this, who says we cant find a way to move faster than light. that's all I'm saying, you are exactly correct in your comment with our current understanding of physics, but perhaps one shouldn't speak with such finality?

[jorgepeterbarton]

@bbizzy89 '..unless we find a wormhole or something...' [such as the overthrowing about most of what we think we know about general relativity]

we are still quite a way yet though, we always work with our current understanding as its the best way we have.

[bbizzy89]

@jorgepeterbarton i get that. though traversing a wormhole is like cheating in that we're not moving 'faster' than light but getting to the destination before light does. that being said, i recently saw something about "cracks" in space-time where light moves faster than light speed, then there was the reports that CERN propelled sub atomic particles slightly faster than light speed. We should keep our minds open is all I'm saying.

[jorgepeterbarton]

@bbizzy89 i do have some issue with the cern thing, mainly journalists saying that its paving the way for time travel. there have been theories within general relativity about tachyonic neutrinos, although problems of causality arise, not real problems with math. thats one problem its only neutrinos which are particles that don't do anything! not heard the program you talk about, where can i find? the universe is expanding faster than light-its the actual space expanding, not things through it.

[bbizzy89]

@supahcanfly your in 8th grade and your looking up science vids instead of chasing pussy/dudes? (idk if your a guy or not) i commend you! we need more people interested in this shit. I'm 22 and cant get enough of this stuff, of course i have a degree in philosophy so this is my forte but that's beside the point. Good for you my dude stay curious!!!!

[supahcanfly]

@bbizzy89 no i really like girls ( a lot) but space is my favorite thing and theres no subject for it and science is about atoms and other crap

[supahcanfly]

@bbizzy89 oh yeah and im not a geek... im a really good athlete for someone whos the youngest in his grade

[bbizzy89]

@supahcanfly Good looks mang. Chase the poonani but grow your mind to, it actually helps with the ladies to, being deep and brooding and whatnot. But you have to be careful, Kurt Gödel literally drove himself into an asylum pondering deep concepts and the universe,the nature of reality and things like that. And that was the guy that Einstein thought was the smartest person around.

[myosat]

I like telescopes

[Heinekeem]

FUCK YOU GALILEO!

Ratzinger

[ftlqed]

It would be cool if they had flat screen home hubble telescopes with the old stary night that you can zoom around the universe in from any point. So, if you wipe off the RGB, the computer can interpolate 60mhz to 60ghz for almost any nm images.

[5star555555555]

NOVA should be the most popular show on TV.

[sungamones]

Thanks Galileo for the telescope. Great man of God.

[vudu8ball]

RThis sort of thig always makes me feel calm and free. there is not a damn thing I can possibly do in this life that will matter one iota. Might as well enjoy myself!

[MrCribbss]

eeeeen super massief zwart gat... :p

[1blackaura]

the universe is microscopic

[MrDBarch]

If the universe was created from the big bang, and spread out evenly, then it has a center..... if we can only see back in time to that center, 13.5bya, then on the other side of that center, is at least another 13.5byears to cross to get to the opposite distance from the center where the big bang happened. I don't think it's rocket science to realize if the universe IS finite, then it IS a sphere. Do they expect it could be a triangle or something?

[alexamada]

37:00

if water boils at 212 degrees F, how can this planet have water at 400 degrees F????

[MrDBarch]

@alexamada Maybe it's at 400 degrees 'cus there's no atmosphere to evaporate it? something like that .... perhaps the water exists fundamentally at a constant boiling state, but doesn't boil as it would on earth due to the different planet conditions..? my best shot at it lol.

[alexamada]

@MrDBarch well actually i think water itself may be at least partially responsible for the formation of an atmosphere.... at least on this planet. but i assume it works pretty much the same anywhere. also, there's a huge gap between 400 and 212. water may be able to boil indefinitely in a system where its regularly replenished, either through an outside source or recycling. anyhow, what im saying is "different planetary conditions" is just way too vague

[MrDBarch]

@alexamada You're right, it was vague. I guess my point is, that water would need to be converted into a different state, and subsequently need replenishing. without an atmosphere, what would provide the water a place to stay in a converted state? I meant different planetary conditions in the sense of the presence of an atmosphere, or not, the presence of heat, or no heat, the presence of a circular orbit around it's star. or large, uneven elliptical one, etc. etc. a good question.

[shoshanish]

@alexamada different pressures

[alexamada]

@shoshanish oh i see. is that why water boils in a vacuum?

[shoshanish]

@alexamada doesnt water boil in a vacuum because of the lack of pressure?

if it can freeze fast enough, its possible for ti to stay that way.

im sorry i didnt respond earlier, youtubes newer layout makes it had to know when i have comment replies.

[adamrspears1981]

@shoshanish I've seen liquid water boil at 40 degrees F. Yes it boils in a vacuum because of less atmosphere exerting pressure on the liquid water; or as you stated a lack of pressure. I don't think there is such a thing as a frozen vapor state of matter. The reason why something (like water) is frozen is because its molecules lack the thermal energy needed to vibrate them enough to have the properties that (water) vapor has. Really water naturally wants to be in a vapor state.

[adamrspears1981]

@shoshanish ...As I was previously explaining, water wants to be a vapor. The only reason water can also be a liquid or a solid on Earth is because, (1) the Earth's sky is heavy enough to press down on solid or liquid water to keep it from doing what it naturally wants to do which is exist as a vapor, & (2) at this amount of pressure pushing down on water from the sky, its temperature (the measure of the rate at which its molecules vibrate) will also keep it from naturally existing as a vapor

[alexamada]

@shoshanish its ok. already got answers, though. thnx anyways

[BlameRepublicans]

Water's boiling point is dependent on it's pressure. Water boils at room temp at low pressure for example, will remain liquid at higher temps if it's at higher pressure.

[alexamada]

@BlameRepublicans ah ok. well thanks to you and sho for clearing that up. didn't realize pressure was a factor.

[jugulator0]

@BlameRepublicans another great invention.......The Pressure Cooker!

[AtomosDemocritus]

Could a spherical universe exist because we only see the vectors of spherical wave that intersect with the center of the observers frame of reference? The edge of space would be measured always in constant proportion to the quanta created by the observations?

[MrDnbfreak]

any1 else see the white dot go but at 37 min

[madwestboy]

@2:44 costing 120 million :(

so thats where all my tax money is going

[Blackjuicez]

@madwestboy science inculding Nasa gets 2% of the taxpayer money... soo u might want to find out there the 98% goes but it is not at @:2:44

[madwestboy]

@Blackjuicez do they have private funds??

[Blackjuicez]

@madwestboy I'm not sure! but I think I can safely say they probably do... Science is important to us as humans and to the planet we live on... the few dollars they get should not be view in a negative way.... it is becuz of science we have internet, youtube, computers and the life saving medical technologies.. watch this video on youtube "SciCafe: Life the Universe and Everything with Neil deGrasse Tyson" watch 39:00..Dr. Tyson is President of the board of the Planetary Society.

[madwestboy]

@Blackjuicez thats all good what about the money they spend to look at urtra deep fields,making propes,constantly sending people outer space to the moon,building a telescope to look zillions of light years away..s.e.t.i,didnt find aliens yet :(

we dont need to know about all that stuff.but they spend money on cause they can.but i must admit it is intresting to watch it on yt lol..i have lots of it im my playlist

[henrikmk]

@madwestboy We actually do need to know: The more we know about the universe, the more we learn about ourselves. It was through studies of Venus that we learned that CFC gases hurt the ozone layer of Earth.

Studying the Sun helps us understand climate changes and protect electronics.

A particular method for studying distant stars helped invent the MRI scanner, used to discover cancer tumors in the human body. It gave a Nobel Prize.

[randomtwit]

@madwestboy better there than on more stupid guns

[henrikmk]

@madwestboy The Large Binocular Telescope is funded internationally with money coming from Italy and Germany as well as the United States. Out of the total tax budget, you probably paid a few cents for this instrument, which will work for decades.

[mkkitten1]

35:53 acouple years....lol! It's beeen 5 and their not even close....

[creekstar7]

I just LOVE watching NOVA episodes like this one, but I can't help but curse the show when it makes me feel so small in this universe... XD

[LittleAliceLover]

@creekstar7 Haha, i know how ya feel. I find this all fascinating!!!

[yahuichiu]

I am almost down on my knees for the breathtaking views that shows here....Just how lucky to be able to be here. Totally overwhelmed because of the splendid images......Galileo rocks! Thanks to upload!

[CaptCrunge]

@theprettygirl45

I know what you mean.Not having a natural gift for math can feel limiting.

However passion and curiosity often compensate for any gap in analytics.

I believe Einstein himself said "imagination is more important than intelligence" or words to that effect.

[MrAmethystium]

@CaptCrunge Einstein is fake.

[theprettygirl45]

I've never been proficient in science, nor in math. However, I am so mesmerized by this. I'm obsessed with all of this beauty.

[FuckNewbs]

First time I've seen this one GREAT UPLOAD XD!!

[fartchunk]

thumbs up if your venus was blury too.

[Suolperos]

Lol alright, who was the ONE PERSON out of 75 people to openly dislike this film? This isn't some chair-tossing, brain-draining bullshit like Jersey Shore, this is NOVA! To me, this is intellectually equivalent to admitting to a crowd of strangers in a public place to being a bedwetter.

[sankoboy]

I bet that water planet that is 400degreesF has some weird sea creatures!

[TheSteady0]

@sankoboy Water boils at 212 F so water wouldn't exist on a planet with that temperature.

[sankoboy]

@TheSteady0 remember, different galaxy, different properties.

[TheSteady0]

@sankoboy You're right on some degree, the waters boiling point won't be 212 F since boiling point is related to the atmospheric pressure over there. Different galaxies doesn't have different properties when it comes to common physics, the laws are always the same. Also, I'm quite sure that it's located within our galaxy since we can't zoom in that good into other galaxies since they're waaaay to far away.

[lokey745]

Thank god for galileo!!!

[ubcphysicsyangbo]

One can only imagine the shear excitement, shock, and a torrent of other feelings that must have swept over the mind of one Galileo Galilei, one of the forefathers of modern science, upon viewing the surface of the moon. We take so much of our modern knowledge (& comforts) for granted....

[lmos26]

Remarkable quality for a 360p... Thank u for uploading!!

[2eelShmeal]

@lmos26 Imagination is better than any video quality. (imo)

[Zurround100]

How the hell are we supposed to comprehend something being so far away that it takes the light 13 billion years to reach us when you can talk to anyone on Earth within a small fraction of a second and talk to someone on the moon in one point three seconds? The human brain is not designed to comprehend distances like that when we evolved to think of traversing the Earth as huge distances.

[wiretransfer]

10:34 "Lemme just take another hit of this Four Loko..."

[Boogyman4050]

How do you really define the difference between an amateur vs a pro? Just education or those who are paid? Other than PHD, I'd have to guess the real difference is those who are paid and those who do it for fun. Using the term amateur/rookie implies stupid or unskilled. To me, that is not right. Some amateur astronomers are brilliant.

[213SEMPERFI]

Thank you for sharing. This is awesome<3

[Boogyman4050]

Always love NOVA space shows. Thanks for posting.

[shamelesshussy]

Thank you so much for the upload. Saturday night sorted!

[scientifiqueable]

Telescopes are the basis to our knowledge of the universe and this technology in space will undoubtedly keep young scientists yearning for answers and motivated for years to come.... :-)

[haterallday]

Wow i've never seen glass melt in real time.
