Thats the coolest part, ie the old thing about a chain only being as strong as its weakest link, and a chain of sufficient length couldn't even hold a feather due to its own weight.

The CNT's (if near perfectly atomically aligned) and give them an INSANE tensile strength, some numbers I just googled puts steel at about 620 MPa (0.62 GPa) whereas the CNT's that have been made are pushing 80 GPa.

Obviously something this big is already gonna be a multi-governmental collaboration, but all you need then is to find the easiest reasonable sized meteor to DART our way, and catch that bitch on the way by.

For the atmosphere part, it would have to be an entirely geostationary orbit, and so really you would have the same winds as expected on skyscrapers (plus a bit). All this the tensile strength has more than enough wiggle room for.

Material costs aren't too bad too considering its nearly a hydrocarbon, and the strength only requires a fairly thin cable - in equivalent terms imagine the material for a road as long, we've got millions of km's of them, 100 is easy

Shit you and us all.

Worst part of nano is that error is intristic, how much error is where the fun comes in

As a nano engineer, youre 100% right - with the added slowdowns of safety research. Many of these particles are entirely different beasts on a nanoscale, an example commonly used is microscopic copper is just copper, nanoscopic will have you dead within the hour if inhaled (dont quote my timeframe on that one).

That being said many cool materials are still coming out, just aren't yet at that commercialized availability level yet.

For example graphene has the potential to replace copper -at least in high performance applications- cause its got some fucked levels of conductivity

Edit for some more examples cause I'm a nerd about this stuff:

Carbon nanotubes make vantablack, the material that can absorb 99.9% of visible light (not that exciting beyond a party trick commercially, but in areas trying to minimize electromagnetic noise this is revolutionary).

Silver nanoparticles have been shown to have passive disinfectant properties, leading to the possibility of a cloth that you could run dirty water through and make it drinkable.

And my favorite being we've already created the carbon based structures (can't recall if it was nanotubes specifically) with theoretically high enough tensile strength that if made a couple kilometers long could be used to lasso an asteroid and create a space elavator

alright where's that XCKD, imma make another package distribution method to 'unify all the methods'

Quantify and quantization youre saying have different root words? their similarity in definition and to the Latin word quantus is just coincidence? (whoops nitpicky ahem ahem)

And of course it was hypothesized but never proven, double slit pushed it towards theory/fact

but also I'm not sure if you know where the line of quantum mechanics to newtonian mechanics are, cause newton definitely didn't theorize too much about the energy of light

the amount of projection in this comment, how'd you bring us to politics in a single sentence??

(wow I'm talking to KDE themselves)

I came into godot at the 4.0 release, and the built in tools are already amazing, even performance wise for 3d. There's no easy visual shader editor -not sure if unity has one - but it forced me to learn opengl es, which at the end of the day is a lot more powerful

quantification of light as a particle and the theory of its wave particle duality yes is by definition quantum mechanics, which was proven first by the double slit expierament. Up until then 2 light sources never canceled each other out so it was assumed light is 100% quantifiable and a particle.

(quantify is actually where the word quantum comes from)

noise canceling headphones you're good for tho, the existence of waves is a different subject

Edit: and IG if we want to talk about fundamentally untrue then, your comments also wrong cause its a pretty big thing in science that light ISNT just a wave... but of course I'm not being nitpicky right?

I mean like the analogy holds until quantum mechanics - which is pretty good - no need to nitpick

Delete a bunch of files from /bin then try to get back to a working system (hard mode)

I think Debian doesn't cause I used it in some containers

I mean like that's getting pretty nitpicky if you need them to hand list it.

Especially speed like you want the functions they optimized?
