Seizure First Aid.
Learn it. Share it. Know it. Use it.
100% correct medical information on tumblr for once; also consider calling 911 if you don’t know how often the person has seizures and ESPECIALLY if the seizure has lasted 5 minutes or more (which is why the watch is critical)
This is so important!
Really good friend of mine from work back home had seizures a few times on the job. This is crucial information.
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.

this wins over other pro-gay commercials because you had no idea he was gay and then you can’t tell which one is his husband
they are showing them as people
not as gays and straights
fuckin love this commercial
can we just talk abotu the fact that the husbands arent even bringing the drinks over theyre just standing there next to the drinks and chatting
fuckin useless husbands
they are showing anyone can be useless. Even gay people
they are saying that it doesn’t matter if you are gay or straight. You can still be a useless person
this post got better
The lower I get the higher I’ll climb
and I will wonder why,
I got dark only to shine
And I’ll light up the sky,
Stars that burn the brightest,
Fall so fast and pass you by,
Spark like empty lighters.
