Have you never even looked at an astronomy book? They orbit sideways, not up and down, for one thing. It flies like a frisbee not a swirly nonsense thing.

Your article literally says that the animation is only slightly inaccurate (the rotation around the sun is supposed to be tilted 60 degrees). The planets do trace helixes as the sun orbits the center of the galaxy.

Can someone explain why the expanding fireball has a smaller fireball expanding outward on the left?

>>1004911
Probably because something in or around the bomb wasn't symmetric.

>>1004911
Complete guess, but maybe because the reaction expanded/progressed in one direction faster than the other in the milliseconds after detonation

>>1003574
Literally in tears

>>1003670
coldplay. one of the songs of their first album I think parachutes

>>1004911

My guess would be a hydrogen/thermonuclear bomb which uses a small fission bomb (the primary) to set off a chain reaction in a much more powerful fusion stage (the secondary).

They do go off milliseconds apart and produce a distinctive double spike in gamma rays, which is how they're detected.

>>1007391
it is a 29kt fission bomb called Teapot - Apple 2

>>1001205
The problem is more than that. It's that some planets are shown as consistently behind the sun, meaning that if you looked at the system from the reference frame of the sun, the planets would orbit a point some light-minutes offset from the sun. That is not what happens.

In case anyone is wondering, that's what flux-core arc welding is. An electric arc melts the wire and penetrates the steel being welded, combining the two pieces.

The cloud between the wire and the melted steel gas that's produced by the flux. Flux is a chemical that's put inside the welding wire to expel oxygen and generally just to protect the weld from the atmosphere. Additionally an external gas (normally CO2) is also used.

>>1000407

I don't really understand what electrophoresis has to do with a really ugly codon chart, and how either of them have to do with literal fingerprints. Maybe it's a metaphor? DNA fingerprinting is a thing.

I guess the problem is that there isn't exactly a direct biology analogue to the general format (abstract, mathematical model -> graphical representation -> real life). I would've done a DNA or RNA sequence on the far left, a ribbon model of a protein in the middle, and basically anything relating to an organism on the right.

That webm isn't showing Sanger sequencing anyway since a bunch of bands seem to be the same size. And... sort of? I guess basically, yeah, but it's done with those funky glass capillaries now, so not exactly.

>>1019787
Ayyy, I know this one. That's an AC to DC rectifier - it 'converts' the alternating current you get from the wall into direct current usable by computers, cell phones, etc. That basic construct is in just about every electronic device you own that plugs into a wall, except things like fans and lightbulbs.

one depends on the other and both are unique and allow to identify you.
you probably didn't think this much but people jumping on you for this are kind of assholes too

>>1023611
Almost certainly, but it's a moot point. Just like anything made "with carbon nanotubes!!11!", it's totally experimental and, while certainly interesting, not at all practical yet. It will take years, probably decades for graphene to have any kind of market presence in the real world.

That said, research like this is absolutely fundamental to the advancement (and longevity) of our species.

>Without DNA there would be no fingerprints.
All of these statements are true for literally your entire body if you zoom in close enough. We could use iris, tongue, butthole or elbow skin wrinkles scans for identification as all of these things are unique for you specifically as well. Fingerprints don't depend on DNA any more than anything else.

>>1023964
I still have to hear about the unique elbow skin patterns that are used to identify you.

>>1023964
>Fingerprints don't depend on DNA any more than anything else.
So you are saying fingerprints are just as dependent on DNA as any other human feature?

Actually fairly little engineering work, but I'm starting my own company rather than working as an engineer for someone else.

For a "typical" electrical engineer it's office work: you're sitting at a desk for most of the day, either designing electronic components (could be power supplies, could be processors), programming, or validating your designs in simulation, prototypes, etc. If you saw an engineer at work, generally speaking, he'd be indistinguishable from an accountant or a lawyer.

That said, engineering, even just electrical engineering, is extremely broad. I know a couple of guys in the power industry at utility companies. Their day-to-day work is driving around town, inspecting substations, running tests, and generally making sure that when you flick the light switch, it actually turns on.

Are you thinking about becoming an engineer?

An air bubble in the fuel was detected. Their fuel was being super cooled and due to the fucking boat in the launch zone, the fuel started to warm up. By the time they got around to the second launch countdown a bubble had formed. So, they scrubbed the mission completely.

Yes and no, while the radiation does hit any item second (after the light burst) the heat-wave which on average hits several seconds ahead of the shockwave is what's causing the burning. Seeing as the heatwave is radiated outwards from the blast some name it too as a form of radiation. The nuclear (read radioactive) radiation does not burn through metal, depending on what form of metal it may or may not pass straight through however.

Selling your services to the government as a private business is different from just straight up getting tax money given to you.

Why do you not have any issues with the thousands of other businesses that not only sell goods/services to the government, but also overcharge and/or directly receive tax money from massive subsidies?

It's only spacex that comes under the crosshairs and it mystifies me that so many americans on 4chan so vocally hate one of their most successful high-technology companies for wildly inaccurate and untruthful reasons.

I could understand hating spacex if you were, for example, a russian or chinese. But to falsely complain about spacex receiving tax money, while you'll simultaneously cry about NASA not getting enough, or demand congress funnel more money into pork-barrel projects like the SLS; I'm just fucking mystified by it. It'd make more sense if someone were literally paying people to post these sorts of attacks because the sheer willful ignorance for it to be genuine strikes me as extremely unlikely.

I'm so torn on this. The amount of things that have to go right boggles my mind. Now, do I think that life exists elsewhere? Most definitely yes. But self aware ones I want to say no. But that universe is so vast that trillions upon trillions of events and conditions exist so mathematically it must be elsewhere, right?

Gives me a bit of anxiety when I think about this stuff. We'll never know for sure. And the observable universe is a small portion of what actually exists!
And that's not to mention possible other dimensions or other universes.

And all this from nothing. Nothing!
And not just a small amount like a few quarks but this vast universe.

And here we are, able to ask these questions all because mammals were able to rise up and become bigger because the small ones survived the impact that wiped out the dinosaurs. And that's only one of thing.
Look at Venus almost identical to size in earth. Yet it turned into a searing hot planet that has a crushing atmosphere. The few pictures that Russia has looked like a really neat place to explore.

it costs 60 million to make the rocket and 200k to fuel it. similar to many other modern machines. the boeing 737 costs around 70 million

fuel costs are high for rockets obviously compared to other vehicle, but the instruments themselves are much more expensive. jet fuel for NY to LA costs in the tens of thousands. it also lasts for a few hours, but jet engines are extremely efficient compared to rocket engines (they also do not have to carry their own oxidizer)

Am I the only one bothered by the people that don't know the difference between a Comet, and a Meteor? Be more worried about a Meteor people, not achunk of ice... The Ice sublimes, making the coma, or tail, hence the name. The friction from entering the atmosphere alone would burn up most comets, so you would need a hell of a large one to do anything serious. Where as any decent meteor is essentially a slug. Even if it explodes on entry it can do serious damage

>>1046503
I dont want a comet to dump all his kinetic energy in our atmosphere. If the object is large and/or energetic enough, it doesnt really matter if it impacts on our atmosphere or the surface. I mean asteroids are indeed more dangerous, but you make it sound like a comet would just turn into a shooting star

I thought that was the light doing something to the aperture or something. I don't know. Maybe /p/ might.

>>1046535

Indeed, I made a generalization, but I added a caveat, saying that in order to do real damage it would have to be of rather significant size, where a meteor could be a great factor smaller and do as much if not more damage. Most celestial bodies have substantial energy, so I consider that point moot. I absolutely did not say that a comet couldn't be dangerous, but a comet vs. a meteor of comparable size isn't going to be as devastating.

>>1046549
I am sure that Jupiter found it utterly devastating. All the other times that it has been struck by celestial bodies were nothing. After this, how will it ever cope?... *HEAVY SARCASM*

>>1046559
>Most celestial bodies have substantial energy, so I consider that point moot
fair enough. if it fucks the earth, it fucks the earth
>but a comet vs. a meteor of comparable size isn't going to be as devastating.
If by size, you mean mass, this is just wrong. Comets have way much more relative velocity. Due to their eccentric orbits they would hit earth at about 3 times the velocity of an asteroid. that means 9 times the energy

>>1046582
Meh, that's when considering a worst case scenario comparing comets like ISON and the like., but meteors can reach such ludicrous speeds too The point I was trying to make was the difference in composition and what that would do, although as you already pointed out, even a comet coming in and burning up, without even reaching the ground could prove quite problematic to say the least

>>1046611
I'm not sure there is a comet small enough to fit your scenario.

>>1046562
You know what I mean. Scientists weren't expecting it to leave marks on a giant ball of gas as long as it did.

>>1046626
Again, size isn't the point that I am trying to press, it is the composition of them. With enough foresight we can melt melt an oncoming comet, or even break it apart as safely and easily as it gets, where with a meteor we don't have that option. Some of the best options are to paint one face white and have the photons gently nudge it out of our path, attach some sort of booster rockets to nudge it, or go fucking Armageddon on them. All of these options are difficult, yes, but I would prefer we have to find a way to deal with a comet than a meteor, hands down

>>1046611
>that's when considering a worst case scenario
actually no. my 3times the speed example was pretty moderate. Even a relative speed of 70km/s could be possible with a comet. Point is, comets are faster. I dont think composition even matters at that kind of energy level.
But "fortunatly" asteroids are far more likely to impact our pale blue dot

>>1046646
They travel at speeds comparable to a meteor, and worst case they hit us after slingshotting around the sun when they reach their fastest, and YES, they can be traveling at 3 times the average speed of an asteroid. but again, the threat that they pose is miniscule compared to asteroids. A Heavy PGM rich asteroid is a slug travelling at our planet, not a ball of ice going a bit faster. All that means is that its more work to catch the thing and intervene, and less to actually deal with it. Where catching an asteroid is the easy part.

3MB, 640x360px

>>1046650
yeah, but isnt it the hardest part to catch up? You pretty much have to get your spacecraft into the same orbit and same period as the target in order to gravity tractor/laser/bomb/whatever it. The deltaV must be insane to get it in such an extreme orbit.

>>1046657
We usually have decades of notice if something is even going to get close, and then years of knowing that it is absolutely going to hit for sure, after it passes through the keyhole. Depending on the composition of the asteroid, if it is rocky, then the speed difference would make dealing with a comet easier. If it were a super heavy/dense PGM rish asteroid, then not really. With that much time we wouldn't even need to expend much fuel to catch up o it. A few good slingshots, catch it at it's slowest, paint the face of the comet black to absorb photons rather than have them bounce off, et voila. Catching either is challenging, but we have already managed to nearly catch asteroids, so with a little more effort, catching a comet isn't entirely out of the question. Destroying a speedy comet could potentially prove to be far easier than moving or destroying an PGM rich asteroid

>>1046665
Errr, I meant that if it is a rocky asteroid, then dealing with it could prove easier than simply catching up to a comet. I got mixed up

>>1046690
Indeed. We must be prepared for such inevitabilities, otherwise...

>>1046690
Catching one could actually be more simple and faster than landing on one depending on how they do it.
If we just ram something into it at full speed we don't have to worry about gravity slingshots and shit. Just aim and fire so the orbit is adjusted closer to earth. Then, when it's closer, make some final adjustments to get it in orbit.

There is no doubt in my mind that asteroid mining is going to define the coming generations. All it will take is getting one in earth's orbit and space flight will be changed forever.

>>1046731

I am excited as hell about it, but am also terrified, depending on which lagrange point they decide to use. I don't know how I feel about having a big, super dense/heavy rock just waiting for something to go wrong and fall on my head

We have already landed numerous probes on asteroids, and essentially shot them to examine particles for a deeper understanding of their specific composition, but the force required to move a celestial body into orbit and to maintain it is nothing to scoff at. I would say that THAT is the hard part, not approaching, grabbing, or landing on one

>>1046739
They most likely won't use Lagrange points. We only have a limited number of them and all but one pretty much have an assigned purpose right now.
They'll probably be put in orbits further than the moon or maybe even orbits around the moon itself.

That sounds better than some nutjob trying to put it in orbit around the earth itself. I stress again, it is much more difficult than the other anon made it sound. To get it there is hard enough, and to maintain the orbit takes alot of work as well. You are then talking about going back and forth pulling materials from it, be it manned mission or drones? It would be a monumental achievement in and of itself. The day we manage that, I'll be like....

>>1046784
>You are then talking about going back and forth pulling materials from it, be it manned mission or drones?
The whole allure of asteroid mining is manufacturing in space.
Instead of launching 200 tons of metal to space in prefabricated chunks we can just build massive shit in orbit.
There may be certain rare metals like platinum and gold that we'd want to send back to earth but that's as easy as chucking it in a capsule and deorbiting it. The fast vast majority of ore would stay in orbit to be used there. It would make long distance missions much much cheaper.

>>1046798
I can't see them doing this with anything other than a PGM rich asteroid, in fact, that's all that I have heard people like Bill Nye (whom I have talked to about this with) and NdT on his podcast talk tabout, as there really isn't any return otherwise. Initially, to actually make asteroid mining a reality, I would say that the main allure is you would be affecting the market of what we had previously considered to be a finite resource. You would make alot of technology much more affordable, and would make a mint while you are at it, and THEN you could feasibly turn it into some sort of springboard for manufacturing in space, but that is down the road

Allthough, the price tag of 10k/lb to get something into space would also be a good insentive for people to get creative for us to quickly manufacture in space, so we could be wrong and it could happen alot sooner. Wouldn't that be something

>>1046810

>>1047103
Moon factory would just lessen the problem of getting huge shit into space while orbital factories would eliminate it entirely.
Imagine if we had to build everything else in modules like we do space stations right now. Even if we made the modules bigger, nobody would be building sky scrapers or stadiums.
If we eliminate the idea of modules entirely then the construction possibilities are infinitely expanded.

>>1047111
I just can't see an orbital factory being realistic. It's not easy working in zero g

>>1047111
but there's a reason, those are modules. how would you do it?

>>1047115
Artificial gravity is, as of now, unrealistic due to the fact that all of our space infrastructure is made of aluminum pipe cleaners and copper foil but if we were able to use heavier, stronger materials like steel I beams, we could make something like that easily.
>>1047124
Piece by piece construction. Like everything else.
Right now it's much easier to manufacture and ship an entire module to space because manufacture it up there means your shipping everything that isn't used PLUS extra.
They don't want to get into space and find they're missing a screw to that damn IKEA bookshelf.
If we're able to create a surplus of material in space then the only limitation is the amount of real estate in orbit.
Some things may still be easier to build in large modules (like cruise ships down here on terra firma) but, for large structures like buildings, piece by piece is easier.

>Not like it matters, the human race will be long dead by then.

Getting out the front door is most of the challenge. If we can manage to get a toe-hold on one other planet, in another solar system, without going extinct first, I think we have a pretty good chance of still being around (in some form or another) to see Andromeda and the Milky Way make out.

Think about how Earth's first reproducing organism once ruled the whole planet. It was the only species of organism in all oceans, at first, and it filled them. But earlier than that, and not even very much earlier, there was the very first individual of the first organism. And if it had died before reproducing, then that would've been it. A planet-spanning species snuffed out before it got started.

Well, we're also at risk of snuffing it before we even get started, but if we do get going, I think we'll expand like the first organisms. Exploding across the galaxy, plenty of mistakes and disasters, social, political and technological collapses, lots and lots of mayhem. AND YET, an unfathomable population explosion for the species.

>>1047454
Yeah, but 4 billion years is a long goddamn time
If humanity manages to get out the door and build an empire, that empire has to stay together for billions of years to maintain interbreeding populations.

Not necessarily. The conditions for life were already present. For all we know life might have started up more than once. Possibly in different areas at the same time.
But first we must figure out what that initial spark was that created life. Then we will have a better understanding of the statistics of it happening.
My feeble mind can't even begin to comprehend existence. I wish I could.

>>1047202
>means your shipping everything that isn't used PLUS extra
thats pretty much what I meant, The payload of one rocket is one module that is more or less ready to use. I dont still dont see how your method would be more efficient/safe or I dont understande it.
Are you talking about 3D-printed stuff out of material from an asteroid or a space elevator or some other other fancy sci-fi gobblygook?
Even then, even on the surface of earth, construction with modules is easier and takes less steps

>>1047872
Building stuff on earth and shooting it into orbit severely limits what can be built by cost, material strength and, most importantly, weight.
If all the material is already in space that completely negates the weight factor.
If, among that material, there is a significant amount of iron we can use steel for construction which eliminates the material strength factor.
If we don't have to worry about module size and being able to fit the finished product in a rocket we can build much larger things as well.
tl;dr raw materials in spaces afford us larger, stronger and cheaper infrastructure.

Many would disagree and say that it's the Soyuz, because it is cheaper to use, elegantly simple and not over-complicated like what some would say the SV is, and just flat out more dependable. Alot of the qualities people want in their rockets. It comes down to your philosophy. To do more, the costs increase exponentially across the board, where the Soyuz is just right in the middle.
