  1. I would modify the design to remove any wobble making the results easier to see and record. Rebuild the machine but have it radially symmetrical both in weight and in dimensions, so the centre of balance of the device is exactly in the centre of the main shaft. Then point the whole thing at the floor and suspend it from dead centre using a cable and load cell. Then record the data recorded by the load cell onto a laptop. if you wanted to eliminate radial movement you could build two identical devices spinning in opposite directions. Once you have your weight over time data you can then determ
  2. Minmus, i find it easier than landing on the mun and the science benefits per landing are far higher and there is a lower dv requirement for the actual landing itself, although there are a lot more biomes on the mun meaning extended missions to the mun are far more profitable. But yeah, i always hit minmus first
  3. Just watched a few videos on this stuff on youtube and read your explanation and the whole prospect of probability waves baffles me
  4. Sorry I'm really confused. So let me say what I'm thinking and you guys can correct me where I'm wrong and let me know if and where I'm right. Radiation is the transference of energy into subatomic particles with no mass. But the energy stored in these particles can only be measured by assessing the waveform, ie a high frequency radiation contains more energy, My layman's opinion is telling me due to the fact that a particle with no mass cannot contain "momentum" in the conventional kinetic energy sense the actual energy is not contained within the particle itself but in the waveform. So the m
  5. My original comment did indeed state that the altitude effects the escape vector...
  6. Aerobraking and gravity assists are two very different things, The altitude of a gravity assist only really matters if its a powered assist (ie where you burn at periapsis) in which case you want to be as low as possible in order to take maximum advantage of the oberth effect. With a passive gravity assist your angle of escape (or final orbit for gravity assisted braking) is determined by your altitude at periapsis, the lower the altitude the greater effect on the final vector. because the game doesnt use Nbody physics you wont gain experience a notable speed difference between a low peri and
  7. Ah ok I just thought radiation was just considered energy and is therefor without mass or momentum.
  8. If some of the kinetic energy is lost as radiation then would that not violate conservation of momentum?
  9. So, I'm a bit of a noob to physics, I enjoyed it in school but never really followed it up in my adult life and particle physics was never on my schools curriculum. I'm starting to get interested in it once again, and was wondering about the properties of electrons. Firstly if I fire an electron at a surface and it is absorbed by the surface, does it impart a force in that surface. Secondly does the act of firing the electron impart a force on the electron gun, I would assume the answers to be yes since electrons have mass like any other particle but would like confirmation. Also is there a ma
  10. I imagine sales of tinfoil hats will soar... Also would you be able to use the microwave power plant to remotely cook popcorn.
  11. Tidal energy is the future, its a little like wind energy but more reliable and with a much smaller footprint.
  12. What is an EmDrive and how can it seemingly defy the laws of physics by producing a force without the need for a reaction mass.
  13. Indeed you are correct, which verifies my point that the difference between 0 atm and 1 atm is far greater than 1 atm to 2 atm
  14. firstly the number of humans would depend on the nature of the mission, if the mission was to set up a small colony and terraform the planet, then perhaps only a few hundred would be sent in some kind of stasis. However if the mission was to populate and colonize an already habitable planet then there would likely be a few thousand, as well as donor DNA to ensure genetic diversity. The mission would require a crew capable of being woken from stasis at the first sign of a problem and be fully up to speed with the ships systems although the bulk of operations would be automated, at the same time
