welcome to a new segment on the channel I'm calling strange science back to my roots folks I'll be uploading one of these every week or so just to pay homage to where we were at one point this channel used to be called science studio and for good reason and it's still my first passion in each video will be a series of scientific facts that I found to be strange or baffling in one form or another think of it as trivial knowledge but cool trivial knowledge are you ready for this one let's begin one light-year is a unit of distance not time although one can be derived from the other it's the distance light travels in a vacuum in one year approximately seven trillion 878 billion four hundred ninety nine million eight hundred and ten thousand miles from a time perspective it take light this long one year to travel this distance now let's consider a galaxy say the sleeping beauty galaxy it's over seventeen million light-years away this many miles away when Hubble and other large telescopes turn their mirrors towards Sleeping Beauty they see the galaxy as it was approximately seventeen million years ago this is because it takes light 17 million years or thereabouts to reach the lenses of our telescopes from that point in space in the same fashion of sleeping beauty suddenly ceased to exist we wouldn't know about it for another seventeen million years we literally peer deep into our universe's past to back to earth Einstein once said compounding interest is the eighth wonder of the world he who understands it earns it but he who doesn't pays it in 1626 native americans sold Manhattan Island to Peter Minuit of the Dutch West company for twenty four US dollars converted if the company had saved a mere $1 of the proceeds in a bank account that accrued eight percent compounding interest today that account would be worth over ten trillion dollars this is not a joke three an internet exchange point is a physical wired exchange point from multiple networks on the world wide web the advantages of IXPs are numerous the primary ones being cost efficiency and available bandwidth the largest internet exchange point is in Germany abbreviated Dec IX and hosting max data output of approximately four terabits per second that's roughly 100 thousand times more powerful than a typical Wi-Fi router what you're looking at here is a graphical representation of every major internet hub connection in the world Dec IX resides somewhere in the densest cluster for all intents and purposes this is the world wide web for the world's strongest acid flora and timon ik acid this hyper corrosive chemical is formed by mixing equal ratios of hydrogen fluoride and antimony pentafluoride the compound is 2 times 10 to the 19th that's 20 contagion times stronger than the purest sulfuric acid and has a pH of negative 31 point 3 but you didn't know that scale went below zero I sure didn't if you've seen the movie alien then you're aware of what strong acids can do corrode metals dissolve organic compounds burn through glass while the floor antimony acid is actually stronger than that floor antimony acid is typically stored in PTFE containers when synthesized five Jupiter if it was 85 times more massive than it is now enough pressure would exist at its core to sustain thermonuclear reactions the same kind of reactions that fuel our Sun the result a binary star system that's two stars in one solar system on a sidenote we're actually rare we only have one star in our system most systems that we found have two or more earth would mimic the fictional planet Tatooine from star wars and likely witnessed two sunsets every 24 hours if this were to happen to Jupiter that's all I have in this episode be sure to LIKE subscribe and/or leave a comment this is Salazar studio thanks for learning with us
