[spoiler]There is no such thing. Oreos should be eaten dry with a non-permeating lactose film to aid salival digestion

If you can give some metrics on what "optimal" is to you, we can tell you how to test.</spoiler>

[spoiler]>Good
>IQ test

Pick one.</spoiler>

Accelerometers use a lot less power than GPS receivers, at the moment.</spoiler>

[spoiler]>>4264742
It's possible to get that error down to billionths, if you can afford the biggest gyroscopes and shiniest magnets. When you get to that point though, you may as well just be using GPS.</spoiler>

[spoiler]Because chaos theory.

If my device has a compass with 99% accuracy (kinda generous) at directional measurement and I walk 100M in a straight line, then turn right, then walk 100 again, then do the same a third, then a fourth time, that's an error margin of 0.04, potentially out by several metres already. That's without counting problems in measuring inertia accurately when your tool is any smaller than a suitcase.</spoiler>

In other words, X^2 is a more powerful function than 2x.</spoiler>

[spoiler]Oh look, the internet is back.

Sorry about the delay, things got slow

The amount of the ring further away increases linearly. The amount of the close side's weight increases exponentially. The effective centre of mass, the centre of weight, moves towards the close side of the ring as the close side of the ring gets closer.</spoiler>

[spoiler]test</spoiler>

[spoiler]>>4263997
No, because the earth has angular velocity such that it is in stable orbit. The ring has no such velocity.</spoiler>

[spoiler]>>4263980
Slowly or quickly?

If it stops fast, splat. All of us are dead, except those in space at the moment, and they're probably dead too when they try and re-enter without guidance. A 300M/S acceleration will mess up anything and everything on the surface.

If slowly, the effects are more mild. Gravity increases slightly from our perspective, solar activity becomes a bit more problematic, and not much else.</spoiler>

[spoiler]>>4263959
It does, but you don't seem to know how gravitation field topography works. ANY deviation from equilibrium, even by a micron, and the ring will fall at some point.</spoiler>

[spoiler]>>4263915
>implying it can

Earth deviates +/-20KM between equator and poles. It's definitely not uniform enough to be ignored.</spoiler>

[spoiler]>>4263903
False. Assuming it's perfectly rigid, you can have any gravitational field you want and reach a balance point.</spoiler>

[spoiler]>>4263869
Not damn fast enough. for this to actually stay up it would need to have a centre of mass in geostationary orbit</spoiler>

[spoiler]>>4263797
A, definitely. I'm also having trouble working out why you'd think B is possible, lol</spoiler>

>alcubierre drives are infeasible

Moon landings and organised civilian air flight are infeasible. Sub-micrometre computational devices are infeasible. Bite me.</spoiler>

[spoiler]Define dark energy.

And probably not, given the stuff's not dense.</spoiler>

[spoiler]>>4263665
I read that as BEE-CAZ-OO

Also, fallacious logic. That you have a theory is not evidence.</spoiler>

What he said

G-force is the amount of force you're feeling from acceleration over a time period. You're always going to experience the same amount when going from 0 to 3000, but if you do it in a second that's 300G instead of the 1G from doing it over 5 minutes.

Everything is going nowhere.

The answer is "don't be retarded, women can't do anything right"

>>4260658
damn gurl u 1 nigga with atttude lol stand up to their faggots lol

>>4260650
I didn't say that, my dear troll

>>4260653
No there cant fagg neckbeard
