Bombmites discover your warhead and eat all your charges, creating a dud. A mission to verify gravity, build a rocket (the payload is the omnipotent space-time stabilizer) with a beam attached from the bottom the rocket engine node, falls over and fuel tank explodes.

The velocity of a gas is dependent on its molecular weight and the temperature. In most cases it takes very high temperatures to reach a reasonable ISP. If we argue that IR has a gas temperature of about 2500K thats a rather puny ISP. If you really want to get the ISP up you have to convert the heat to electricity, in which case you lose half of the energy, at least, in order to create a gradient, presumbably with space. With the remaining half you create a low voltage wavefunction, then transform it into a high voltage wave function, whose waste heat you could scavenge. From there you have to use a rectifyer to create a high voltage, you also need a UV light/X ray ion generator. At which point you ionize particles then place the cations in a electric field and accelerate them to 10000s of m/s. This is how a fission reactor based ion drive system works. You can use sunlight as a source of heat, but again it has a maximum ISP because of the average 'temperature' of light coming from the sun. You can grab some of this with solar panels and use this to run transformers that run the ion drive systems. A third, rather messy option is to take antimatter and matter, let them react, and then convert the high energy photons into lower energy photons using a number of high energy gamma absorbers, this will tend to create alot of nuclear byproducts, which in turn will heat up and produce things like neutrons, etc, and eventually you have heat and a very trashed up reactor lining. More sophisticated versions of heat generation are fusion reactors (although technically once it gets going it may actually produce more light and x-rays than heat). Another method is light channelling, where you have some system of gathering light in the inner solar system, and creating channels that provide heat and light to the outer solar system whereby spacecraft can feed, stock pile energy and go about the business they need to do. This in mid/far future.

I think the answer is, if I am reading the press stuff correctly, that they already have produced detectable. The bigger problem right now is they need many more detectors than hey have to make these things detectable unless they are close.

If we accept that at least one of the stars in a neutron binary went SN, the we accept that there are remnants of a nebula. Almost all 2nd and 3rd generations stars are formed as a consequence of nebula formation, so its a forgone conclusion that atoms and molecules in a nebula interact. Therefore have gold from a star traveling out a few light years and undergoing collisions with particles in the nebula is not surprising. Gold atoms are pretty big, they have alot of electrons in their outer shell, and traveling at 0.05 to 0.3 c its not hard to strip electrons off or occasionally add electrons allowing gold to interact with surrounding material by non-collison forces creating a wake of particles that have been accelerated and slowing the gold atoms down. A more difficult question is how do you zip up gold atoms to 0.05 to 0.3c when you have two neutron stars colliding, all but reaching the minimum limits for black hole formation.

Neutrinos are not stearable, you therefore they give you no net thrust, and because there rest mass is so tiny they only give you n = 300MW

I think they are probably correct, but that captures the overwhelming majority. BTW, how many asteroids were we have estimated the volume have we place satellites in orbit of,mthats what you really want to know, that is an aspect of variance that goes un measured,mis density variance a part of the calculations? I know what you are going to say,mits likely minor, but the best statistics when sources of variance are independent are best crossmultiplied.

The evolution of neutron star involves the radially loss with the lower mass remnant retaining most of the angular momentum, in the form of its spin. Because the neutron star is made up different phases some experience tidal forces from the adjacent star, this creates a ver strong magnetic field. According to that article, the field causes erosion of the gas in the adjacent star. http://phys.org/news/2016-05-tides-binary-star-neutron-stars.html I couldn't find the article i was looking for,mthe above talks about why neutron stars merge. http://www.nature.com/nphys/journal/v11/n12/full/nphys3574.html http://www.nao.ac.jp/en/news/science/2014/20141014-neutronstar.html

I'm not going to get involved in this argument but I will say this I have got intonarguments with well structured scientist outside of my field, time would eventually showcthat my conclusions at maximum where off by a maximum of 8% and the well credentialed scietist by 62%. The major difference is that I admit my error and the well structured scientist only admits about 50%. The reality however is that I purposefully took the devils advocacy because I saw their arguments as pompass and unstatistical. I actually wanted their argument to be true, but could not prove it because it was mainly based on the fact that 'im an expert in the field so this is how i interpret all the data, except this little elephant in the middle of the room, that i conviniently want to ignore'. so with alot of years I tend to see the black swans and tend to look for them and propose them to keep the ivory towers challenged and reforming. The basic problem with structured science from natianal research labs and well established universities that I have found,mthe more renowned the institute the more sometimes you have to pull them to get them out oof a rut. I had the same problem locally trying to convince my peeps that we had to dobetter statistics, that ours were not showing all the variances and corrections. Sometimes when you do that, removing the statistical chaff, you sometimes get a picture of what is left can be rather interesting. When you are talking about roids you are talking abou things that have different kinds of life histories, a bunch of things that arecwell characterized, alot of views are only a few pixels, there may be structural variances and fortuitous rolls. So these are best handled by setting the confidence interval correctly. The there are things that roll in from deep space, covered with ice that get captured and blow off their volatiles, the models may be troubled and give inaccurate results based on all known models, so these could be black swans.

Its pretty well behaved as long as you keep the ph up, It looses oxygen the moment you treat it with acid, which makes it ideal to use with salt water. You can rescue a tank in the midst of a vibrio outbreak by simply creating a salt brdge between a saturated solution of MNO4, a small platinum electrode, and a multimeter. You can thus control the redox potential of the water using the multimeter and resistors. You could use the permanganate dirrectly but the MnO2 precipitates. Right so the point, you can treat living organisms with it, and they might feel better. The issue of MnO4 is the weight, you get the equivilent of 1.25 O2 with th added weight of 1.5O a K and an Mn. Its crystalline at STP but you could mix it with a stable fuel and no catalyst, again you have to keep the pH up. You could potentially store it on a bed of calcium carbonate to maintain its buffering capacity. There are others of this type, a much stronger example is dichromate, its about the most powerful oxidant that i know of at low pH. Its also environmenatlly unfriendly as heck. If you want to do any testing with this you have to do it on a small scale, don't think you can mix 500 ml of organic with 500 g of KMnO4 (purple) and all may go well until boom. The rate of organic reactions rises 2 fold for every 10degrees c. So that at room temp it might take 10 minutes to rise 10c, 5 minutes for the next 10c 2 minutes 1 minutes, 30 seconds 15 seconds, 5, 2, critical boom. A small glass petri-dish with a few milligrams each, cover it with parafilm and leave it, a dirty brown residue means you have formed MnO2, meaning that its unstable at ambient. Once you show something is stable at small scales work to large scales using a temperature probe, if temperature begins to rise mix with a good dilute base and spread out. Dont repeat Texas City.

No prob, 90 M for 50 kT. Does this mean we will be building stations that look like balloon kitty cats. Does that now mean the hideous looking spacexships we saw in spore will become real life?

Yes, and the rise of their competitors did not help either. And also the fact that there are perspective problems 'i.e 'don't feed the bears'. And what in the heck did happen to Russian space last 24 months anyway? Is the fall in QC written up yet? Sounds like a risk to me. I don't think this is going to change Space Xs pricing, as soon as contract space opens up they are filling it with orders. Theres one thing about spaceX being on terra firma they have to play by the rules. There is a privacy risk associated with sending packages over seas. You have to look at everything,mtransport costs, risks, intangibles. When we look at the non-concrete cost stuff SpaceX is a way better choice. And its alot of positive PR you wont see with a Russian rocket, although space X does grapple the limelight. How much would we really care about beam if it were not for the spaceX launch it rode up on?
