  1. Adaptation require selection, and base on what advantage ?
  2. Let have a discussion, how to improve this concept, by increasing the results ?
  3. With a spacecraft of 13 500 kg with food and water, and a engine of mass 3000 kg: we could in theory achieve 1 second every 2 years, so 1 minute is achievable in lifetime Its to put relativity in context, in a funny learning experience.
  4. What will be the economical cost to have your ex-wife (or husband) having one year more than you do? If you where the same age... Im beginning calculation right mow, it may take some time The VASIMR Rocket: (https://en.wikipedia.org/wiki/Variable_Specific_Impulse_Magnetoplasma_Rocket) Results presented in January 2011 confirmed that the design point for optimal efficiency on the VX-200 is 50 km/s exhaust velocity, or an Isp of 5000 s **************************************************************************************************** For now Im taking the relativistic equation: As a basis for calculation. This equation come from: In the frame in which the clock is at rest (diagram on the left), the light pulse traces out a path of length 2L and the period of the clock is 2L divided by the speed of light: From the frame of reference of a moving observer traveling at the speed v relative to the resting frame of the clock (diagram at right), the light pulse is seen as tracing out a longer, angled path. Keeping the speed of light constant for all inertial observers, requires a lengthening of the period of this clock from the moving observer's perspective. That is to say, in a frame moving relative to the local clock, this clock will appear to be running more slowly. Straightforward application of the Pythagorean theorem leads to the well-known prediction of special relativity: The total time for the light pulse to trace its path is given by The length of the half path can be calculated as a function of known quantities as Elimination of the variables D and L from these three equations results in the relativistic equation first mentioned. ********************************************************************************************************* The rocket equation: https://en.wikipedia.org/wiki/Tsiolkovsky_rocket_equation where: g0 = 9.8 m/s² and Isp = 5000 second, first assumption for the VASIMR m0 = Initial mass and mf = final mass *********************************************************************************************************
  5. I worked all day to understand the actual Physics correctly, Im to this: From Wikipedia and terms arranged I continue my work on it, c = light speed; v = the speed in earth referential; a = acceleration in earth ref.; t = the clock in the spacecraft without the terms arranged t = time in earth referential where t = time in earth speed; a = 9.8 m/s² https://en.wikipedia.org/wiki/Space_travel_using_constant_acceleration So time will be contracted, kind of, so we will need to continue our acceleration of 9.8 m/s², the fact of speed limitation is corrected by the time dilatation. Im to it now... https://www.ibiblio.org/ebooks/Einstein/Einstein_Relativity.pdf This is for linking his theory to https://en.wikipedia.org/wiki/Minkowski_space#Minkowski_metric Minkowski that was use to arrange terms. No, we will use this energy to warp space. No, They are right under this assumption, But my spacecraft may still explode, but not for that
  6. Again, you are right: Im working actually, on a detailed answer...
  7. To explain that fact we must refer to Aether, but its not Physics, since Einstein law.
  8. I wish i could had done that, in some event of my life Albert Einstein said:
  9. It is now time for the ultimate reference: Einstein himself https://www.ibiblio.org/ebooks/Einstein/Einstein_Relativity.pdf Its always good to revised.
  10. The actual Physics, tell us that nothing could go over speed of light, whatever the referential is... So, it is not Physics.
  11. Usually am radio wave are going through matter more easily. it may be use: https://www.quora.com/Why-cant-radio-waves-transmit-through-water, Im looking for more... The answer requires that you understand electron orbitals and the amount of energy that is required to kick an electron from a discrete lower orbital to a discrete higher one. When a photon (light, radio, x-ray etc) passes through an atom, an electron in the atom can absorb it if the photon contains enough energy to kick the electron to a higher orbital. If the photon doesn't contain enough energy to be absorbed by the electron, then it simply passes through. Due to the discrete nature of electron orbitals, electrons will only absorb photons of particular wavelengths (energies) I took it from the web, its not from me
  12. Why I don't understand the Lorentz factor correctly ? The Lorentz factor or Lorentz term is the factor by which time, length, and relativistic mass change for an object while that object is moving. The expression appears in several equations in special relativity, and it arises in derivations of the Lorentz transformations. The name originates from its earlier appearance in Lorentzian electrodynamics – named after the Dutch physicist Hendrik Lorentz. It is include in the famous Einstein Equation: Where velocity is the velocity as seen by the "stationary" observer as a fraction of the speed of light Note that velocity always increases. The rate at which velocity increases (Newtonian acceleration) decreases. You get closer and closer to c but never reach it. I can't achieve to understand, why when we reach 1 year, we should cut our rocket engine, to save gas, even if we are in a 25 years trip. Lets say that there is air in space. What my rotor located on the spacecraft, that will be use to measure the spacecraft speed, is going to show, if we are continuing acceleration indefinitely? Again, Tank you for your answers
  13. How to retrieve this process from the cell to not see it being destroyed by the magnetic field. If a magnetic field will do, Maybe you mean using that: I doubt, it will do, but you may improve to concept ? How to make this protein across the cell itself ? It is a sin like some of mine, but that's certainly not what you mean
  14. Im giving a try: Yellow: 590 - 570 = 20 The yellow color in eyes referential: green + red: 730 - 500 = 230 minus the yellow = 210 The energy difference (within some pigment behavior): More energy in the eyes referential, but the same color. The color in case 1, modified by the eyes referential, darker, please...
