      Utter fantasy, you will know this one day, SpaceX is a scam, a squillion dollar one who, like NASA; have done precisely FA in space. We have nothing up 'there' and never will, its not possible. Go ahead and rage, its cold hard truth and every human on earth will know it in the end. Check it out or be duped fools - your freedom of choice. Have a great day all.

      0:45 ~ There were not "40 formulations" or "57 Formulations". It was #biblical {needs citations, would need to locate the times i found them} #YorkRite metaphor of lose your head=#40. ~ Spray #WD40 on airplane bolts during servicing bare threads and nuts; #PBLaster is a better penetrant or #capillarylube (#turgor air pressure helps), and the #gremlins of vibration would cause objects to fall from the sky. ~ if not done on the ground, happened via thread lube, the reason someone invented #ThreadLock and possible clue why their color is blue, to fight YorkRite or BlueWhite UGLE #roundhead mystery #WaterOfLife is bleeding or pressure releasing the blood of not our #clans (they intend to kill the letter K #klans, because that DNA is listed as enemy of England, and the Vikings never used Fire Funerals). ~ I personally like Red as the color of #ThreadLock, halt accidents and machine failures, rust is an enemy, yet you do want #galvanic or #ionic bonding (not #oxidants, #oxidative) or machine force mechanical #torquebinding.

    I work with composites, mainly fiberglass, however recently I began working at a company that manufactures aerostructures for commpanies such as sikhorsky. Every single one of the 10,20,30,40,50,60 etc layers has to be perfectly laid 100% flat by hand, working in a clean room, absolutely no dust or ANY kind of debris (which we refer to as "fod" for foreign object damage) can cause a fuckup and make two layers not bind properly. In this application, which happened to be blackhawk helicopter components, there was NO fixing any mistakes. If you screw up, you throw the part away and start again. Vacuum bag every 3 plies or layers, and one final vacuum bag at the end as a final debulk and it goes into the autoclave like that. So you can imagine how long it takes. Some parts were few layers, but side door to a blackhawk could easily be almost 100 layers, with insane extremely cool layers made of a material that has metal mixed into the carbon fiber so they could essentially "wire" the panel, without any wires. Like a conductive layer coating one of the plies. I also worked on this guy's yacht for a little while putting my other background to use, and he had no idea what he was doing. We were working with Pre-preg at that other facility, which means the material, be it carbon fiber or fiberglass, would already be saturated with resin and it would have a backing on each side you have to peel before placing. Did I mention that you also have to avoid stretching it while also not allowing any air or anything else in there? Pre preg fiberglass is the most sticky, freaking annoying thing in the universe. Anyway this guy fell into a common fallacy that carbon fiber is just the best composite. Unless you are taking advantage of the fact that it weighs slightly less for its strength, which he wasn't, then you are ending up with an inferior product if you continue to add enough layers so it ends up a similar weight to what the part would have been if made out of fiberglass. Fiberglass is FAR stronger, especially with the newer stichings and materials available today, however it will ALWAYS be heavier essentially.

    Stop making money off of videos discussing American made materials and ideas if you think they are so "uncivilized" for not using the Metric System. Keep calling us if you need more economic or military aid because you can't defend yourselves in World Wars. 4.7 Billion dollars in WW1. Arms and munitions in WW2. Ireland and the UK would cease to exist without the US. "BuT YoU DoNt UsE ThE MeTrIc SyStEm" "SeNd AiD We CaNt DeFeNd OuRseLvEs LoL"

    On Mars there's no chance of that Methane exploding I'm guessing since there's no O2 anywhere. But this rocket will make an entry on earth too when it returns right?

    in the future you could launch a 3 printer orbitor in order print space craft modules and assemble them in space and use robots to the assemble the space craft design in orbit with this 3 printer orbiter it would also be possible to print circuit board with this orbiters imay be possible to print electronic components in solid blocks
    you need to experiment with 3d printing in 0 gravity before you do that
    some one take this idea. this method would save costs it would make possible to up load designs and make prototypes in orbit , whole engines and drives could be created in ordit this would the first steps to a space dock and saver build cost and
    materials could be delivered by drones this system would be fully automated

    The Brilliant website is well um brilliant, lol great video.


    The one constant I keep hearing is COST, this is a hurdle that we must clear if we’re ever going to truly advance technologically. When it comes to scientific advancement, medical advancement, scholastic advancement, etc. we’re going to have to find a way for cost to be a non issue. Just imagine how much more advanced the human species could be if we didn’t waste time, money, and resources on killing each other, I’d say that we’d probably have humans landed on Mars already. I understand that it’s a easy thing to imagine but a difficult thing to achieve but it must be done because our existence moving forward depends on it.

    I know I may get a lot of criticism by saying this ... Do we really have a need to go to Mars ...? I mean ...the amount of time energy and money that we spend... is this all just for curiosity...?? Or we all have come to a conclusion that Earth is gonna be inhabitable very soon...and so we all are moving to Mars... If yes... Then why not put this effort in saving our beautiful blue planet ... You seriously think going to Mars is gonna be some great achievement by us.. well it'll be for sure if we go there to do some research... But going there with the intention to dwell in ... is just really not wise...we haven't even discovered our oceans yet... And here we plan to go to a dusty planet where there is no oxygen , no life , nothing called nature ... Just a big red mountaneous planet ... And we still are gonna be proud at the cost of everything that we sacrifice ... again heading towards our own extinction... And if you really wanna know what happens when some of the few remain... Let's say after an apocalypse or a nuclear War.... Watch THE TV SERIES "THE 100"
    .... You'll get a clear idea what you need to pay for just to survive...!!
