do they make 2 different sizes that are close enough that i can put one in the other kinda snug?
Modern conveniences, GPS, radar, etcBut not only that, practically all nations are in debtYou can run a nation and invest money in a nation while it is in debtThe big concern is if the debt surpasses the GDP which for the US, is about 33 trillionIn order to survive as a human race, we will have to learn to colonize other planets and moonsWe cannot simply go like this for 200,000 more yearsIn fact, by 2,000 years, we will have exhausted all the energy from the EarthIt will be completely useless 2,000 years into the futureWe landed on the Moon because of the Space RaceSince there was an intense race between USA and the Soviet Union to see if they could land a man on the Moon, NASA invested billions into the program.
You didn't specify the size you need, but 16ga steel tubing will telescope with a size 1/8 larger or smallerThe problem is finding those sizes in shorter lengthsMetals Supermarket is a chain that sells cut pieces at reasonable pricesThey have competitorsWhen I needed some 5/8 square steel tube to fit inside 3/4 and outside 1/2 one place thought they could order it in from Houston if I ordered a full lengthWhen I called around the Supermarket had it in stock and would sell me any length These are not intended to telescope, so it will probably be necessary to sand the outside and inside - I put emory paper around a split wooden shape to take off the problems Aluminum tubing is available in certain sizes that will telescope smoothly, like 3/4, 7/8, and 1 But usually you have to buy at least 6' and finding the 7/8 can be a hassle.
NASA has made some of the most important discoveries known to man kind, and theoreticaly, we can live in spacewe are planning a base on the moon i beleive in 2020 and on the moon lies to problem to our energy problem, thats Helium3 if im not mistakenit will completely get us off oilplus on the moon solar panels are much more effective so that would also be a benefitAnother reason for going into space is that earth only has a limited amount of time before something horribe happens and if we are ignorant and dont spread into space we will all die and mankind will be gone foreverNASA is more important than you think and is actually underfunded.
No, I don'tI think the US is able to fund NASA and work on solving other problems too, these things are not mutually exclusiveI would like to see more public-private partnerships with NASA, it's happening but not as much as it couldI do not see the benefit of gutting one program that provides work to highly skilled workers in order to 'get the workforce back to work'That sort of brain drain does not make sense to meWe'd be far better off if we'd spend less at the Department of Defense and more money in pure research; and then allowing private enterprise to apply the results of that researchWe'd be better off if we invested in educating people to do technical jobs, perhaps even tie some entitlement programs to training programsWe'd be better off if we spent money on repairing and upgrading infrastructure instead of things like propping up sugar, corn, and other commodity prices.
