  1. Banned for triplicating a banned emoji.
  2. A modern turbojet engine uses the mass from the air to accelerate it, the exhaust velocity is cut to a few hundred meters per second affording a very high thrust momentum per fuel burnt the equivilent ISP is in the 10 of 1000s. There are two types of drag in flying, there is form drag (differentially side drag) that decreases per unit volume with increased radius, thus if mass is proportional to volume, the side drag per unit mass is reduced as mass increases. There is also lift associated drag, that doesn't change with volume. Side drag makes speed a problem with smaller objects, and because speed is a problem it disallows smaller craft from flying at very high altitudes, except in cases with massive wings, such as the solar impulse. The benefit of being large is the ability to gain altitude, but that requires higher powered jet engines that have large air throughputs. Your typical rocket at liftoff experiences almost no lift drag or form drag because it is not moving, all of its losses are gravity in the first 15 or 20 seconds of flight. As it travels up it begins to experience form drag and side drag, but in most cases side drag almost disappears and the boundary layer collapses back on the plume, the force is thus the MACH force on the nose-cone, this typically occurs between 15,000 and 30,000 feet where air is 2/3 to 1/3 surface density and declining rapidly, beyond this a rockets speed and upward motion move it out of air quickly. There would be a definite benefit of launching a rocket from 10,000 feet on the equator because the surface gravity is less, its horizontal momentum is higher 1/0.867 that of 30' North. Experienced gravity declines more rapidly, It experiences the air pressure at each moment of flight 10,000 feet higher than being launched at sea level, and the ISP is higher.
  3. To give him a wallet full of a million funds. A swarm of killer bees is chasing the next poster, heavily irritated by cut cheese.
  4. making your words difficult to read is cheating.
  5. tilting your cheating is cheating.
  6. I cut it and send it silently to the next poster.
  7. Noting that you were going back to interfere with my anti-time machine i create a phased temporal shifter that clones the anti-time machine in the moment you leave, that is capable of creating another clone each time you try to destroy them in the past. But you asteroid once again floats right through my ship and back at you. It also detects tracks undedicated attempts to travel backward and creates detonated nuclear bomb whereever your exit point in soacetime is.
  8. The ninjas missed you but godzilla ate you, fortunately he coughed you out, you land in Mt. fujiyama. I wish this thread would end.
  9. First i destroy all the time machines, then i mine the entire system with time machine detecting devices that will blow up the next 10 posters that try to use them, then i shape shift my ship into a donut and both pass through the center and pass out the other side, heading in the direction of the next user.
  10. Because icing roads is alot more fun. Why don't we have panoramic vision?
  11. Granted but you get twisted sister sounds instead. I wish everthing was perfect.
  12. Banned for using the toothy emoji.
  13. Occams razor places the simplist solution, in this case propogating an infinite number of universes is not simple its complicated.
