>laser rifle
Is there any hard-science way a beam of light could benefit from a rifled barrel?

No.

>>44597507
This isn't the most retarded post I've ever seen, but it's pretty close.
>>
>>44597507
It's a free electron laser, and needs accelerated electrons to produce the phase-coherent photons. The barrel is a linear accelerator. The rifling is actually a complex helical arrangement of magnetic coils to condense the size of the accelerator to a man-portalbe package.

It would work for a laser long arm as well, to a point. The extra length could be for focusing lenses, and an optical stabilization system, since to actually work the beam would need to dwell on the target for a length of time.

Honestly, that is reaching for a justification though.

YES

https://en.wikipedia.org/wiki/Circular_polarization

You can pass a beam of light through a filter that gives it circular polarization, effectively "rifling" the barrel, meaning the photons vibrate in a coherent corkscrew.

Before the invention of the ICBM, dropping things from the moon was going to be the preferred weapon of mass destruction.

>Notwithstanding the sanitized memories so many of us have of the Apollo era, Americans were not first on the Moon because we're explorers by nature or because our country is committed to the pursuit of knowledge. We got to the Moon first because the United States was out to beat the Soviet Union, to win the Cold War any way we could. John F. Kennedy made that clear when he complained to top NASA officials in November 1962:
>I'm not that interested in space. I think it's good, I think we ought to know about it, we're ready to spend reasonable amounts of money. But we're talking about these fantastic expenditures which wreck our budget and all these other domestic programs and the only justification for it in my opinion to do it in this time or fashion is because we hope to beat them [the Soviet Union] and demonstrate that starting behind, as we did by a couple of years, by God, we passed them.

And that's probably going to take a long while.

You're absolutely correct, we could probably figure it out if we put enough money to it. Unfortunately, unlike space, it has a much lower possible return for the difficulty involved.

Lying is very useful in politics, anon. The president had no interest in continuing space development, so saying that it would do horrible things to the budget was an easy way to make people accept the lack of money being put into space. It's not like anyone could prove him wrong then, anyway.

He's also from the fucking 60s and didn't have all the information that we have, so it's quite possible that the other anon knows more about current budgetary matters on the topic of space than Kennedy did.

>>44599012
Isn't the POTUS just a rubber stamp that congress uses to approve the budget? Like he doesn't have much to say about it, he just gets given a piece of paper he has to approve. So when politicians bitch about the president's spending and shit, it's just political play, since congress is the one who makes up the budget and pretty much tells the president to approve it?

Anon A is stating facts about science and technology in an appeal to logos, but is getting off-topic in effort to be correct.
Anon B is being pragmatic and (literally) down to earth in an appeal to pathos, but is getting too invested in winning.

What we have here is a clear case of emotion versus logic. Rationality vs Empathy. The trouble is both are losing sight of what the argument was first about: progress. We as humans need to consider both sides of the argument, because our species is divided on many fronts, internal and external. Our debates need not to be about who wins the debate, but about what we learn from it and take away to our secluded cloisters of research and culture.

The bailouts were at least 700 billion, not including the indefinite lending going on every month. The budget in 2015 was larger than ever, and the banks get to borrow (for free basically) via Quantitative Easing 1, 2, 3 and the infinity going on now. So the 700 billion is grossly understated for how much the bailouts cost. But going with the conservative 700 bill...According to the 2015 data, that amount would be about 18% of the federal budget for one year.

NASA's budget at it's absolute peak was less than 5% of the US budget. Look at the previous picture and see how much cash is just FLYING down into Social/Medical programs, not to mention the bailouts which you asked me to compare to NASA's budget.

US could have easily let banks fail and then fund space travel for a long time. Or they could cut back a fraction from somewhere else and the US could have the space program of sci-fi's dreams.

All this to say that, no, the President is not some kind of genius that knows the best way to spend our budget. As an american, can you seriously say the money spent on the Iraq war (1.7 trillion btw) was a stroke of genius us plebs can't comprehend, or was it just dumbfuckery again?

Jumping in here to say:

People LOVE to point out NASA's tiny budget,
BUT if they got "serious" bloated funding it would quickly become as bad as the military for waste, fraud, and corruption, as happens to any program that gets a vastly inflated budget.
The tight budget is restricting but at least there's no rot.

Technically it was part of a larger national defense plan to protect strategic reserves to secure the future, as has been oil policy since supply projections from WW2, which as much as people love to rant about "so oil baron profiteering", mind you even after we've got all electric cars we're still entirely dependent on oil for other products and risk being entirely crippled unless the supply future is carefully managed lest our entire infrastructure collapse in the next century before any alternative sources become even remotely *viable* (as in can be implemented TOMORROW, not some futurism bullshit).
It just so happens the military-industrial complex has become every bit as bloated and corrupted as it was predicted to be.

The real issue is a lack of accountability and generic corruption.

Can you aim a pistol properly for long distance shooting? I'm not /k/ enough to know.
>>
>>44600862
A laser would be more like a film camera than a gun
>>
>>44600862
You can. The problem with pistols is not aiming but how a shorter barrel means a shorter distance that the projectile is accelerated by the expanding gases and a shorter distance the projectile is pushed at a well defined direction for accurancy.

There is an upper limit to how fast exploding gases can expand, so you need time and space to harness it properly.
>>
>>44600915
I guess the part I'm having trouble wrapping my head around is how you aim at something that's the distance a rifle would fire away with a pistol. Could there be sights you could adjust? Could you keep the laser pistol steady?
>>
>>44600944
There's plenty of things you can add onto a pistol to make it easier to aim at distance
>>
>>44600915
>at a well defined direction for accurancy.

The bullet's direction is well defined as soon as it has squeezed into the barrel. Then we just need the rifling to get it spinning, which should happen at the same time, for it to remain that way. A normal pistol barrel is more than enough.

>There is an upper limit to how fast exploding gases can expand, so you need time and space to harness it properly.

This is also bullshit. The gasses have a maximum expansion rate, yes. But that's an upper limit. This in turn means we have an upper limit for the speed the bullet can be given. It says nothing about how long time it'll take to get there.

A longer barrel means we can mroe comfortably get the bullet up to higher speeds. Higher speeds means less wind drift, less drop, and less time for the target to move. The gun itself isn't any ore accurate, but you will be able to shoot it mroe accurately.

The rifle stocks also gives you a better grip on things, locking you and the gun in place more securely, so that you do things in a mroe consistent way. Once again that makes you shoot more accurately. If we're using iron sights the longer barrel allows for a longer sight radius, which also makes you shoot mroe accurately, since a smaller deviation in aiming shifts the sights a greater distance.

>Says the trillions of dollars worth of rare earth metals floating around between Mars and Jupiter.
Unfortunately retreiving them at the moment would cost significantly more than trillions of dollars, so we're going to wait. We're going to wait until terrestrial based scientific progress has made some discoveries that can be applied to space travel. Once this has been acheived going to space will cost less because other industries have laid the foundations. Once this cost reaches a satisfactory level THEN we will go into space without crippling our current economy, because that's what sensible people do. They don't go leaping forth with more enthusiasm than talent. That may be the done thing when losing one's virginity but not when advancing mankind's interests.

The President can fund certain things through executive order, and threatening a veto if the budget doesn't adequately fund a given program is a common tactic.

>>
>>44604117
Basically, a particle and an anti-particle can spontaneously come into existence. This does not violate conservation of energy or momentum.

You can detect these particles by having two uncharged metal plates suspended, in a vacuum, next to one another with an absolutely miniscule gap between them. You can detect an attractive force between them. Particles are spontaneously coming into existence constantly, however due to the size of the gap the wavelength of the particles that can come into being are limited, so there are less particles impacting on the inside surfaces of the plates, thus the plates are pushed together.
