IT'S REALLY FUCKING HAPPENING

From whose perspective?

There are some important questions. First, how much would it cost to do something like this?

We need to send about 160 million kilograms of material into space (See Birch's boot strap estimates in part 2: http://www.orionsarm.com/fm_store/OrbitalRings-II.pdf))

We have rockets available at $2000/kg costs to LEO today in "mass production" mode, which is only about 10-20 launches per year. Compared with the couple thousand launches necessary for a space elevator, $2000 is an unreasonably high upper bound for launch costs.

We also need to include the cost of materials. A space elevator is about 98% steel and aluminum, 1% kevlar, and 1% other such as superconducting magnets. Most of the mass (98%) cost around $1/kg, with an average cost per kilogram of no more than about $10 per kilogram.

Summing the above up, we get about $430 billion in launch costs plus another $1-2 billion in material costs.

In other words, we can have a space elevator for less than $450 billion - significantly less than one year worth of DoD spending, one bank bailout, many times less than a variety of pointless wars, etc. This is well within our reach financially in other words.

>tfw CTMU finally clicks and after a lifetime of seeking you finally, truly understand what reality is

Neutron stars be like, "Nuh uh, you ain't gettin' past these spin-forbidden states,"

and black holes be all like, "Bitch, I shit all over the laws of physics. Where's your Pauli Exclusion Principle now?"

Amirite?

Is this just real scientists ultimate sci fi fantasy or do the physics associated with them hold actual weight? For example, "time slows down". Does it actual slow time or is it just the way gravity affects your bodies atoms?

Another thing. The event horizon data on "Sag A Star" is being proccessed right now and by 2018-19 it should be finally finished up. What exactly should they expect to be finding and what would that change exactly that makes it so important to observe?
