    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.

    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.

    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...!!
