Ok retards here's a lesson on engineering
Say a rope of 1" diameter can support up to 500 pounds and that a 1 mile long stretch of it weights 100 pounds, 1 mile would weight 100 pounds, the next segment would have to support those 100 pounds, the next one 200 and so on until you have a 5 mile long stretch, no biggie you make the rope 2" thick, great now it supports 1000 pounds but also weights 200 pounds but w/e we need to make mine asteroids for silicone or iron, very rare minerals, but now we can only go up to 2.5 miles, plus our original 5 miles, no biggie we make the rope 3" thick, but it weights 300 pounds... See what I'm getting at? We don't have magic ropes, steel rope would end up having a diameter hundreds of miles long, even carbon nanotubes would be miles long and take up more resources than are literally available on Earth, we would have better luck turning the large hadron collider or Harvard's linear particle accelerator into a rail gun and pointing it to space.

Imagine climbing the new World Trade Center and hanging a single spaghetti from the rooftop so long that it's pulled apart by its own weight under Earth's gravitation. This is analogue to a space elevator, only that the acting force in this case is the imaginary centrifugal force due to the Earth's rotation. The space elevator rotating along with the Earth will tear apart by its sheer own weight pulling on it, unless you build it out of not yet commercially viable nanotubes. Even then you'll still need the same amount of energy to lift an object of mass into space, only not from rockets anymore. In the long run reusable rockets will probably be cheaper and more practical than a 300 kilometers long nanotube elevator.

>self aware AI
>Singularity

This is very debatable, but in the grand scheme of things it does not matter if AI ever becomes self aware in order for instances of AI to become dangerous or highly intelligent. Two AI chatbots that Facebook created started to communicate to each other in a new language that only the two bots could decipher, an outcome in which the designers never knew would happen. My own definition of singularity is a world in which a large & lasting change has been made due to AI. The two chatbots creating a new language that they could understand shows how careful programmers need to be in order to stave off these sorts of unwanted run-away functions that have been exhibited. Sure it's just two chatbots, but what happens whenever AI is used in areas where immense risk to human life is apparent?

I remember that, it was a fucking meme you dip. All that happened between them was one chatbot repeating the same word multiple times, they even had documentation of what was happening on the debug console ffs, the thing was bugging out like cleverbot does.
AI being dangerous is the most retarded notion there is, there's a proper article explaining it around somewhere but to paraphrase; an AI will not wipe out mankind for the same reason mankind does not go around digging up highways, destroying powerplants, wiping out crops, etc. Because it took time and effort, it took work to create those systems, and wiping out those systems instead of applying it in some manner to whatever it you seek is incredibly inefficient.
At worst, mankind will be re-purposed to something its useful at, such as exploring (in that humans would take risks that a machine would normally not consider taking, which may open up something new and useful) or research or the arts or something.
So, you know, what we're going for right now with shit like UBI and whatnot, only with an AI in command instead of corrupt, childish, and incompetent aristocrats.

Nowhere in that article nor the paper it's based on do they claim it's inconsistent with GR.

https://arxiv.org/abs/1401.0535

The paper concludes:
"Since most metric theories of gravity besides general relativity predict violations of the SEP at some level, high-precision timing of J0337+1715 should soon produce unique and extremely interesting new tests of gravity."

Does this say "GR is wrong"? No.


>https://en.wikipedia.org/wiki/Criticism_of_the_theory_of_relativity

There are three examples given of claimed experimental refutations in that article, 2 of them predate GR entirely and the other is special relativity not GR. All three of them were shown to be false.

>https://www.space.com/37745-einstein-relativity-tested-by-star-black-hole.html

Same as the first link. Testing, not inconsistent.

So no, none of these are examples of observations GR cannot account for. In fact there are no well controlled experiments which point to deviations from GR.

In future don't just google random shit. You can't even read and you're calling people retarded.

Sounds good but memes get funding. If someone invests heavily in a space elevator project and things pan out the way you describe, the space elevator will be scrapped but it will still have generated high tech jobs, excitement in science and technical advances. High demand for advances in material science caused by the space elevator project may cause your rockets to be half the weight they would have been.

This will take a lot of funding, meaning you're going to have to sell it to investors, board members or even congressmen, who will bring in their own experts to analyze it, call it a hopeless pipe dream, and put you in a worse place than you were before you wasted time and money promoting it.

The space elevator is a meme and it interests me as a meme. If something like that is powerful enough as a meme it can cause politicians to campaign for it even if the experts say it's a pipe dream. In the space elevator example the results of following that pipe dream seem pretty positive.
