Allergies are immune system specific, failed. I merge all quantum space time.

Banned for murky avatar. I can't tell whether is a cube of a 3-D tic-tac-toe game.

Follow vysionone, nothing can go wrong now, he's the guy who always checks for errors and finds them. His track record is exceptional just ask him. Take it to say ninty or so, then ask the question, I'll enjoy.

Uh, guessing, no. I like my solar system better, lots of plot and intrigue.

Ethane can interfere with neurobiology because it changes the permeability of membranes, ita also dosplaces oxygen, . . . . . . . .you will get buzzed from it at high enough concentrations, but then again high concentrations are also explosive.

Banned for finding nowhere.

Driven

Its all a conspiracy . . . . . .

Well since freddino gets to make random stuff, I might as well give it a try. Make Nemesis a planet twice pluto's distance from the sol with devilishly fiendish aliens that seed virus and plaque causing bacteria throughout the system. They also mine comets for hydrogen and oxygen, leaving the metal components in a ball at the center, they compile these into balls every now and then and divert them across the orbits of inner planets, causing the occassional mass extintion event. The also collect huge amounts of lithium and and boron and gel them up hurling them into sol cause spikes of solar activity for 100,000s of years that double solar activity.

Not enough to be useful, aluminum solid propellant is going to be the biggest fuel componet. That basically places it in the programmed flight ascent and descent with OxN fuels basically to touch up on those flights.

This sounds like a bunch of optimistic hand waving. OK you make an SR71 backbird at 10X scale. Modify it so that it can fly at 100,000 feet (20 miles) up and Mach 5. (3200 MPH) what have you obtained. You still have 15000 MPH of dV required for orbit and another 200,000 feet to climb to orbit. Sure you save on fuel, but the technology cost per unit is atrocious. (all of these numbers are outrageously optimistic, you would need a serious afterburner with O2 feed to get up to 100,000 feet and Mach 5 would require serious aerodynamic considerations). Lets talk about the calving problem, eventually you have to release the orbital ascent vehicle, you are at 100,000 feet true atmosphere is at 1:100th or so surface atmosphere, but you are at Mach 5 and the recyclable and vehicle will have serious issues as they separate. Suppose we get to 80,000 feet, turn to 45 pitch and then rocket to say 300,000 meters and release. Right, no problem you release payload, but now the cycling craft is going to come back in, no retrorockets and aerodynamic as hell, and dead engines. Next is has to restart its engines and then find a way to slow down. Lets talk about some problems with SR71, could not take off with a full load of fuel, had to be refueled in flight. Not particularly great climb engines. Gear could not sustain landing many failures. + since you are not going around the world you can replace the fuel with payload. - but you will also need payload for burners to achieve hideous altitudes, plus the weight of burners. - still need retros to reduce the cavitation potential on reentry. - payloads need a launch frame, this could be contained within the cargo bay of the cycler, but that has aerodynamic implications, because of the extreme speeds of low altitude SSTs (typically breaking Mach 1 below 20k feet). This will lessen the crosssectional area that can be fit into the cargo area. + but because the payload itself does not need to survive Max Q cost spent on nose cone and fairing can be removed. + means the payload will conform to sears-haack body - since most of the flight vector is horizontal the entire structure is subject to much more drag, for a much longer period of time. + but because this is jet thrust versus ISP thrust the mass efficiency is much greater (unlike falcon 9 however, most of the weight is coming back to earth, thereforecost). - but that has to be weighed against the fact you have only obtained a minimal orbital altitude, and nowhere the velocity to reach orbit. That means the payload need to carry 14000 dV of fuel (at the equator) required to reach orbit. All in all, F9 is the answer they are looking for.

I wish you could too.

Yeah, this is BS dramatization. They did panic, but in the moment there is no time to act out like that. Also, those meetings, I've been to meetings with a lot of raw emotions out there, never been to a meeting where people talked like that.

If you flip the galaxy over and view from the other side which direction does it spin?

Or to place it otherwise, imagine if you were using solar panels to do this and you had them around stars collecting energy you would need to use a significant number of stars in the visible universe to collect enough one power in one moment to send the pulse. Imagine if the total amount of laser power you can produce in a moment is GW per meter/2 then you would need 1.8e43 meters cubed. 4piR^2 is the surface area of a sphere = 1.8e43 r= (5.65 e43)1/2 r = 7.5e+21 in light years (9.461e15) = 782169 This is to state that if you had batteries sufficient to power 1 GW/sq.meter lasers at a wavelentgh of visible light for a second, then you would need a shell of lasers pointing at a center with a radius of ~800,000 light years. That is approximately many times the volume of the milky way galaxy. If we ignore the power requirements and only look at the space requirements and only look at the space-time requirements, and the power density. There is no point in the known universe where this could be done. It would be silly, it would be like building a bridge to the moon to get a better view of an anthill on the other side of the earth. It would take time, at least 1.6 million years to do, and it would take the technology (or something comparable) that one was attempting to build to create a foundation to complete the task. The laser power density is generous. The current energy production of the earth is about 2500 GW which means for the Earth surface (6400 r). The earths current electrical output is 1/51,550,000,000 th of what it would need to be to be a power source. Alternatively you would need a battery capable of storing 51552611369 seconds of power to produce on Gj, againt batteries cannot be counted on to deliver as sizable amount of power in 1/600,000th of a second so the battering would have to be many 100s of times more powerful. The short answer, its impossible, theoretically plausible but technically impossible.

Don't forget however that light travels as a wave function that does not age in and of itself as it travels. It woukd be excessive difficult to have a high enough density of wave function energy in one space to create a schwartzfield radius. The geometry of quantum space time maybe important, the geometry of such a light black hole might have a shape like a dandelion, but since much of the mass of the dandelion is more in the peripheri than the center the dandelion would have to have many more hairs to have sufficient enough mass to form, with some photons being captured and others diffracted. We did the calculation here once chach the files. To make a black hole large enough to create a drive you would have tobstart using intensely ineregetic lasers in a sphere 200 or more light years across aiming at something about the sizebof an atom. Practically speaking it is not possible to do.

While I do not subscribe to every Hawkings belief the Hawkings radiation is one that i subscribe to, the reason is that there that quantum mechanics suggest that this is the case and there has some verification.
