They flew there on a rocket-ship.

Speed of meme spread is directly proportional to the population size and spread methodology effectivity

There is an unknown factor which affects the validity of our measurements, something that we don't seem to be taking into account.

We call it dank matter / dank energy.

>>8000444
In addition, the the speed is largely affected by disturbances in the environment in which the memes propagate, such as influence from other societies and even the local climate, which may lead to changes in lifestyles and, consequently, cultural practices.

You're fucked with a big black STEM dick anon. Just drop at least 2 of these classes NOW!!

Please explain yourself sir genius.

>>8005121
it's a meme

>>8005121
We can't even control our own climate yet

>>8005121
The latter.

It is not outside the realm of plausibility to get small oceans, the ability to go outside without a spacesuit, and some plant life, but Mars will always be cold and dry relative to Earth.

Consult Martyn J Fogg's Terraforming for an in-depth scientific analysis of the concept for an academic audience.

Did the ISS inflate that module yet that SpaceX delivered the other day?

>>8002063
i don't think they've unpacked it yet even

i thought it was install week after docking
inflate some time after that
let astronauts in after a few months
throw away in 2 years

This doesn't sound great to me. This is a really vague "partnership".

I expected them to announce a firm launch contract for a BA-330 to definitely fly within a year or two. Instead they announced that an Atlas V had been reserved for a possible 2020 launch, which they apparently hope NASA will pay for.

The launch vehicle they're talking about using, Atlas V 552, doesn't actually exist yet. Like Falcon Heavy, it's a planned but undemonstrated configuration of an existing launch system. The dual-engine upper stage is planned to fly in November, but that might be delayed because Atlas V is currently grounded while they investigate the premature engine cutoff on the booster from the Cygnus launch.

So this is really weird, to announce getting all cozy with ULA for a first launch several years down the road just as SpaceX is getting their act together with reusable rockets.

>Does it work?
No.
>Is it healthy?
Depends what you mean by healthy, it won't kill you, but I you'll be constantly exhausted.

>>8006355
How do you know it doesn't work? Have you tried it?

i feel like any of the weird sleep cycles are just memes. theres probably a great reason that we sleep the way we currently do

Is your denominator x^2 +1 or x^2 - 1?

Do you see how your first step has an error?

That's what sci-fi movies and books say, scientists usually look for water and microscopic lifeforms.
However if the contact was made the other way around (the aliens find us first) then it would make sense to assume they're more advanced.

>>8004728
>we always say that they're probably very smart and advanced compared to us?
You mean popular culture does. The reality is that we don't know what life will be like in other star systems. We portray the aliens as smarter and advanced because it makes for a more interesting setting when creating art (movies, books etc.).

wolframalpha have a good app. you can access it via the web for free, or the app for a few quid. does graph plotting, advanced calculus including imaginary and real plots

No, the jews put the gay gene in vaccines to destroy christian values and the white race.
I don't know man, the fuck kind on an answer are you expecting?

>>8003768
>reasoning
you mean facts?

>>8003768
No, just like all complicated phenotypes it's genes + environment + epigenetics.

wow what a piece of shit question
>undefined, highly specific parameters.. what the fuck is "near"
>tries to make the multiple choice hard by scrambling the answer, playing on your brain's shortcuts for memory, instead of offering three random false answers and testing if you actually have an idea of what the correct one is.

yes, all wrong because sqrt(g*r)

>>8003718
Not to mention

>Not even phrased as a question

>>8003637 (cont) or even an hybrid system that uses both conventional combustion and atomic "ammo" if the material of the spacecraft can't withstand pressure from the atomic explosions for too long. I saw a video once about a similar atomic-bases propulsion but I forgot the name of the project, does anyone remember that? the spacecraft had a plate on the bottom that acted like a spring, pushing the craft using the motion generated by the pressure of the explosion below, the explosions were originated by some sort of atomic "bullets".

Project Orion

>>8003715
https://en.wikipedia.org/wiki/Project_Orion_%28nuclear_propulsion%29#Potential_problems

>Danger to human life was not a reason given for shelving the project. The reasons included lack of a mission requirement, the fact that no-one in the U.S. government could think of any reason to put thousands of tons of payload into orbit, the decision to focus on rockets for the Moon mission, and ultimately the signing of the Partial Test Ban Treaty in 1963.

Would it be possible to resume this project with latest technologies and the possibility to launch the spacecraft from outside the atmosphere?

>A concept similar to Orion was designed by the British Interplanetary Society (B.I.S.) in the years 1973–1974. Project Daedalus was to be a robotic interstellar probe to Barnard's Star that would travel at 12% of the speed of light. In 1989, a similar concept was studied by the U.S. Navy and NASA in Project Longshot. Both of these concepts require significant advances in fusion technology, and therefore cannot be built at present, unlike Orion.

I never heard of these 2 projects, I'll look into them now.
