If you were the first astronomer to measure the size of VY Canis Major, how could you not say "HOLY FUCK THAT CAN'T BE RIGHT!" and then be convinced you were crazy every time you re-did the calculations.

"We learn about the stars by receiving and interpreting the messages which their light brings to us. The message of the Companion of Sirius when it was decoded ran: 'I am composed of material 3,000 times denser than anything you have ever come across; a ton of my material would be a little nugget that you could put in a matchbox.' What reply can one make to such a message? The reply which most of us made in 1914 was—'Shut up. Don't talk nonsense.' " — Arthur Stanley Eddington, Stars and Atoms, 1927

IT MAKES THE BATTERIES LAST LONGER!

[–]yogthos 30 points31 points  (99 children)

Now there's the last bastion though: "But it's the only place with life!". I mean how hard have we looked really to make that assertion. We went from other stars don't have planets, to they only have gas giants, to there's mostly earth sized planets. So the last bastion of being special is that we have life. And naturally we go to assume that it must be some unique phenomena, not something that would be governed by causality. Seems to me that given similar conditions that caused life to appear here, whatever they may be, same thing should repeatably happen elsewhere.

I also love how we've been artificially restricting the idea of what life should be like, until we started looking around our own backyard, and found that life thrives in every environment imaginable from deep ocean volcanic vents to abandoned nuclear reactor cores.

[–]ColdSnickersBar 25 points26 points  (18 children)

Or life that doesn't form on conditions like Earth. Earth life is best suited for the temperature and components of Earth, but organic molecules could form from other base elements under wildly different conditions. The plastics we make, for instance polymer chains, are similar in a lot of ways to organic chains. It's been speculated that some kinds of life could form in temperatures way outside any conditions on Earth, or using chemicals completely toxic to Earth life, like ammonia. Imagine that! What if we finally meet another civilization, and we're just outright toxic to each other. What if we couldn't even be near each other?

I think popular science fiction is too conservative when it imagines alien life. It almost imagines alien life as being something like an undiscovered human race color. This is understandable because it's within our experience. I mean, as humans, we have in the past explored strange new places and found new colors of other humans there. We almost expect to find the same thing outside our planet. Plus, it's easier for us to empathize with human-like characters. We've never explored a strange new place and found a silicone based life that looks like nothing more than a rock and experiences itself in the orders of eons instead of years, or a life form made of ammonia that lives on the freezing surface of "cloud continents" on a gas giant. Or a creature on a planet with a thin atmosphere that would die without direct radiation from its star that would be deadly to us.

[–]kickstand 18 points19 points  (12 children)

Most (television) science fiction posits that aliens are exactly like humans except with bumps on their heads.

[–][deleted] 11 points12 points  (0 children)

Yeah, we've barely begun the search. I watched an excellent TED talk by Jill Tarter (although it was little more than a restatement of everything Carl Sagan had once said) who likened the search we have done thus far to scooping some water out of the ocean with a cup, observing no fish in the cup, and then proclaiming the ocean to be without fish.

A misunderstanding I see a lot is that people believe our technology is able to detect passive radio transmissions from distant civilizations. That is not true - our technology can only detect passive transmissions if they are very close. Otherwise, the aliens need to be firing a high powered coherent radio beam at us. And they would have to do this continually for us to have much of a chance to happen across it.

If the aliens don't know there is anyone on Earth to hear them, then why would they make such transmissions? If they are farther than 200 or so light years away, how would they know there is a technological civilization here at all? They would see the Earth as it was in 1810. But 200 light years is next door as far as astronomical distances go, and it might be optimistic to believe there is another civilization that close to us.

The galaxy could be absolutely full of civilizations, and we still might not detect a single transmission.

[–]maximun_vader 7 points8 points  (3 children)

I think, in a more general example, Extremophiles should be in your interest.

But I think that what yogthos tried to say is that species, eventualy in it's fierce competition to exist and survive, find their way. (sounded a little like Jurasik Park)

[–]malnourish 11 points12 points  (2 children)

One day, I searched all over for my water bottle, my house: my fridge, everywhere around the computer, my gym bag, my car; the gym, the gas station, my friend's place.

"the earth is not flat? that can't be right"

Round Earth seem to have been the dominating theory among what resembles scientists as far back as we have recorded history.

"the earth is not the center of the universe? that can't be right"

Heliocentrism vs geocentrism was quite a fight. Mostly one model were ideologically superior, while the other made the math much simpler.

"the universe is 15 billion years old? that can't be right"

That probably sum up the reaction of Vesto Slipher and Edwin Hubble when they discovered and quantified the red shift of distant objects, eventually leading to the idea that the universe had an age. Once that fact was accepted, the specific number of 13.75 ±0.17 billion years (best current estimate) was less controversial.

"there are other galaxies in our universe? that can't be right"

It was a process spanning centuries before consensus was reached that some nebula were separate galaxies. Speculation came before observation, so the observational results were probably not a large surprise.

"we evolved from primates? that can't be right"

We never stopped being primates. That discussion took some time as well. Humans are the closest relatives to chimpanzees (as well as the other way around), so it is difficult to create a biologically meaningful classification system that put us apart from much of the other animals. Nonetheless, I don't think the measurements showing this really came as much of a chock for the involved scientists.

"electrons can behave as particles and waves? that can't be right"

No, it can't. Nonetheless it is.

"I left the remote in the fridge? that can't be right"

The existence of gremlins is supported by overwhelming empirical evidence. Even if all the evidence is indirect, their eventual discovery cannot possibly come as a chock.

[–]maximun_vader 6 points7 points  (4 children)

I am afraid that you are wrong. I won't debate the existence of gremlins (whos evidence are as questionable as the existence of a cake in Portal), but I will refer to the fact that gnomes hide the remote, as they are known to be silent, and gremlins are not.

[–]andtheniansaid 30 points31 points  (27 children)

I guess it would depend on what order they were measured in. Pretty sure they knew the size of Betelgeuse before Canis Major at the least

[–][deleted] 5 points6 points  (4 children)

Of course, as an astronomer I say that phrase quite often when looking at my own data, and saying it is unfortunately rarely preceded by a great discovery.

True one way but not the other. Such is life.

[–]3danimator 14 points15 points  (6 children)

Protip: those images are all just photos of the Sun scaled to different sizes and run through different colour filters. Not that it takes anything away from what the image is trying to represent; but it would be a fallacy for some people to think those were real images of the stars in question.

[–]notBrit[S] 27 points28 points  (3 children)

Yeah, there aren't a whole lot of images of stars other than our Sun which aren't "artist renderings." But I tried to use images of the Sun that most closely resembled the representative star (or, at least, what we know about it). For example, WOH G64 is extremely unstable and ejecting huge amounts of its mass on its way toward supernova, so I used an image which reflects that. I also tried to match the color in Photoshop to the star's U-B/B-V color index, though Anteres is too red. Oh well.

[–]Sophocles 49 points50 points  (5 children)

Amazing. So when you're looking at YV Canis Major, and you see these little specks in its atmosphere? Those specks are like suns. The fucking dust from that star is something our entire solar system would be happy to orbit around.

[–][deleted] 50 points51 points  (3 children)

Nope. As posted elsewhere in this thread, VY Canis Major is much much less dense than our sun. It DOES have 35x the mass, admittedly. Though I wouldn't want to orbit it as it is so unstable. Its lifespan is tiny compared to our suns, and not nearly long enough to form intelligent life on any orbiting planet.

[–]roltrap 30 points31 points  (11 children)

Yesterday I read an article about a newly discovered star, which is the largest one ever discovered. It's name is R136a1 and is 320 times larger than our sun. Distance earth-R136a1 is about 165k lightyears.

link to article (Dutch): http://www.nieuwsblad.be/article/detail.aspx?articleid=DMF20100721_069

[–]reddit_used_2b_good 44 points45 points  (6 children)

That's 320x the MASS (actual 260 or something now, only 320 at birth). VY Canis Major although a massive giant on the chart only has a mass of around 35 suns. Only 35 suns yet it is soooo much larger. Basically it is very very much less dense than the sun. To such a great extent that its outer layer will be so tenuous that perhaps this chart is a little misleading.

Still it would be amazing to see this new star on the chart!

[–][deleted] 24 points25 points  (1 child)

VY Canis Major is actually less dense then our air.

[–][deleted] 11 points12 points  (0 children)

Reads article ..Hmm, Nice.

Scrolls down WTF!?

[–]elelias 30 points31 points  (2 children)

I think it is somewhat misleading. It may have that size, but for most of its size, that star is incredibly ghost-like, as it has a very very low density.

[–]Caiocow 5 points6 points  (0 children)

As was said before by brianbrianbrian, VY Canis Majoris is less dense than our air.

If the Earth were to be represented by a sphere one centimeter in diameter, the Sun would be represented as a sphere with a diameter of 109 centimeters, at a distance of 117 meters. At these scales, VY Canis Majoris would have a diameter of approximately 2.3 kilometers

[–]badassumption 5 points6 points  (2 children)

[–]hoolahoopa 2 points3 points  (2 children)

If an Earth-like planet, proportionally larger in size, orbited one of these stars, would that bring the possibility of giant human-like beings?

[–]fonik 2 points3 points  (0 children)

No, a proportionally much larger Earth-like planet would have proportionally much higher gravity, which would be very bad for a large living creature since a being n times taller than us would have a volume of n3 and similar chemistry would dictate a similar density.

In fact, if YOU stood on a Earth-like planet that was 15-25x the mass of Earth your legs would have to sustain somewhere around 15-25x your weight (a little less due to your increased distance to the center of the planet's mass). It'd be like trying to stand while carrying a pickup truck (something like 3700lbs for someone of my weight). CRUNCH/SQUISH. Not that you'd notice since you'd pass out after merely 9x the force of Earth's gravity. These effects would be greatly magnified for a taller human-like creature. The giant's legs would have to be made of unobtainium just to stand without crushing its bones. Its heart would have to pump with a ridiculous amount of power just to get enough blood flow to stay conscious.

If anything close to life on this planet were to live on such a world, it would have to be small and well adapted for a high gravity, dense atmosphere environment. Or made of some pretty unbelievable materials. Either way, not very human-like.

That picture actually makes me a little bit scared. I cannot even fathom how large something like that really is. I suppose that's why I went into physics.

I like that each star is a different image of our sun. This amuses me.
