Had to go to the dentist a few hours ago and this little girl in the dentist office asked if gators and sharks had their own dentists x]
So I’m know expert on alligators, although a cursory glance of the internet states that they do not have their teeth cleaned (nor do crocodiles. Egyptian Plovers, according to our trusted Wikipedia, do not generally clean the teeth of their reptilian friends. Rather, the crocodiles merely shed their teeth regularly).
Prepare to be learned.
Dentistry is a highly efficient and common practice in the ocean. Parasites of many kinds cluster around all life, in a world so different from our own. Sea creatures very often end up clamoring in parasites due to the nature of the ocean, where life itself seems an oasis of possibilities (don’t believe me? Look up rotting whale carcasses. No, seriously).
As a result, often the larger creatures of the ocean need cleaners. Fortunately, symbiotic cleaners in the form of dentistry can be found just about anywhere. Take, for example, anemone crabs, which clean the mouth of anemones of detritus and residue in exchange for safety: http://en.wikipedia.org/wiki/Neopetrolisthes_ohshimai is one example of such a crab, though there are several.
But we’re talking about sharks.
SOME creatures go to the dentist for their daily visit in the ocean. Sharks, eels, and many many other larger ocean predators go to predetermined “cleaning stations”, where they hang around until they can get their turn being cleaned by none other than cleaner shrimp, which hang out in large quantities waiting to clean junk out of and off of other creatures. Why? Free food, and protection from the predators. In exchange for being clean, predators don’t eat the cleaner shrimp.
Enjoy your day.
Chris Pratt, Ladies and Gentlemen.
This will make a lot more sense to people who have seen the movie.
LETS PLAY A GAME. It’s called: Who directed it TIM BURTON or HENRY SELICK
We’ll start with the 2009 Laika film Coraline based on the novel by Neil Gaiman. Do you know who directed it? Burton or Selick?
Did you guess yet?
If you guessed Henry Selick, you would be correct. Tim Burton actually had absolutely nothing to do with Coraline at all in anyway ever. Reminder: Tim Burton has NOTHING to do with Coraline. At all. But that was an easy one. Let’s go to the Walt Disney Pictures adaptation of Roald Dahl’s novel, James and the Giant Peach next.
Think you got it? Are you sure? Better double check…
Oh, look. It’s Henry Selick again! Tim Burton actually interacted with this project, though only as a producer. Bet that was tricky… Next one! Let’s go to the Disney/Touchstone Pictures film Tim Burton’s The Nightmare Before Christmas.
Have you guessed it correctly? Have you really?
Yep that’s right. Even Tim Burton’s The Nightmare Before Christmas was directed by Henry Selick. Though Burton wrote the poem and created the characters in which Nightmare was based he didn’t have much interaction with the project beyond that. At the time he had already signed off to direct the film Batman Returns and did not want to be involved with the “painstakingly slow process of stop-motion animation.”
Looks like it was a trick quiz. But now you know Henry Selick, whom people rarely know of is responsible for many of the most well known stop-motion animated films. The more you know!
This isn’t even being qeued. This is just being reblogged, because some of you still don’t understand who directed Coraline.
Astronomers have discovered the largest known structure in the universe, a clump of active galactic cores that stretch 4 billion light-years from end to end. The structure is a light quasar group (LQG), a collection of extremely luminous Galactic Nulcei powered by supermassive central black holes.
So that’s cool and everything, but maybe some of you would be interested to know why this is a significant find? Beyond just its record-setting bigness.
Since Einstein, physicists have accepted something called the Cosmological Principle, which states that the universe looks the same everywhere if you view it on a large enough scale. You might find some weird shit over here, and some other freaky shit over there, but if you pull back the camera far enough, you’ll find that same weird and/or freaky shit cropping up over and over again in a fairly regular distribution. This is because the universe is (probably) infinite in size and (we are pretty darn sure) has, and has always had, the same forces acting on it everywhere.
So why is this new LQG so radical? (It stands for ‘Large Quasar Group,’ btw, not ‘Light Quasar Group.’)
Well, let’s try to comprehend the scale we’re dealing with. A ‘megaparsec,’ written Mpc, is about 3.2 million light years long. The Milky Way is about 0.03 Mpc across (or 100,000 light years). The distance between our galaxy and Andromeda, our closest galactic neighbor, is 0.75 Mpc, or 2.5 million light years. LQGs are usually about 200 Mpc across. Assuming a logarithmic distribution of weird shit outliers (if you don’t know how logarithmic distribution curves work, don’t worry about it), cosmologists predicted that nothing in the universe should be more than 370 Mpc across.
This new LQG is 1200 Mpc long. That’s four billion light years. Four BILLION LIGHT YEARS. Just to travel from one side to the other of this one thing. I mean for fuck’s sake, the universe is only about 14 billion years old! How many of these things could there be?
Right now it looks like the Cosmological Principle might be out the window, unless physicists can find some way to make the existence of this new LQG work with the math (and boy, are they trying). And that’s totally baffling. It would mean—well, we don’t have any idea what it would mean. That the universe isn’t essentially uniform? That some ‘special’ physics apply/applied in some places but not in others? That Something Happened that is totally outside our current ability to understand or quantify stuff happening?
By the way, no one lives there. The radiation from so many quasars would sterilize rock.
are you telling us astronomers have discovered something which is literally fucktuple the size of anything else previously estimated to exist
Anything that fucking rewrites all of what we know about the universe needs to get its ass on my blog. It’s giant, glowy, black hole filled ass.
Reblogging for the totally legit usage of the mathematical term “fucktuple.”
This gives me just about all of the science horn. I love space.
Mars. In true colour.
Just so you know, a lot of images of Mars which you’ll see have been manipulated. A lot of them have boosted contrast and saturation. So if you’ve ever wondered – images like this one are what Mars actually looks like.
Why does this not have more notes?!?
YOU ARE LITERALLY LOOKING THROUGH THE EYES OF A ROBOT ON ANOTHER FUCKING PLANET
If you don’t think that’s the tightest shit, you can get out of my face.
i wanted to reblog this so that everyone who sees it can realize just how amazing this is. you are looking at a photograph taken on an entirely different planet. an entire world that has been completely untouched by humanity until only recently. no human in the history of mankind has ever look at those rocks, the soil, the mountains, and the sky until now. and until we finally manage to set foot there for the very first time, no human has ever seen mars from this perspective with their own two eyes or feel the texture of the martian soil on the bottom of their boots. this was only possible by creating a robot, an actual robot, and shooting way out of the reaches of earth and with extremely careful calculations, have it safely land and deploy right where they want it. it’s a robot on another planet being controlled 225 million kilometers away, seeing and studying and sending information for us.
this is the sort of thing you would see in science fiction movies that are only a few decades old. what was only imagination and possibilities back then is now all in this photograph. im looking forward to see what happens in the coming decades
I’m so infatuated by this.
225 million kilometers away and we got it on film that blows my mind
This isn’t what the real Mars looks like, the real one’s in 3-D
