  1. 4 light years however is not very far. With the technology not far above the current one(FFRE) we would be able to send the survey/terraforming ship on such distances. Human travel will require warp though

  2. I think that the temperature, water and stability of the star are the most important ones. Tidal lock can be mitigated with atmosphere and oxygen actually is not needed, as long as there is water we can send the anaerobic bacteria and they will create oxygen(actually such "terraforming"/ biosphere creation missions would probably be more of a norm rather than an execption)

  3. I doubt lead suits will work against bone atrophy

  4.  @robo5013  with time humanity invents new types of propulsion, on top of that, the speeds we can travel increase roughly exponentially. My estimate is that we will break the light barrier in 500-600 years, and from there our expansion/colonization of the universe will start

  5.  @WilliamFord972  those were launched with a cheap simple chemical rocket engines

  6.  @zaeemchogle8219  everything below light speed is possible for sure. Light speed is possible for photons(actually the only speed possible for them). For objects with mass light speed and above is theoretically possible, but requires negative mass energy density, which we don't know how to create

  7.  @hedgehog3180  not really a problem, most likely people still would leave till 60s at least, and it's enough to leave all the offspring

  8.  @robo5013  yes but I doubt planets that have less than 10% of our Sun's light are considered as colonization candidates

  9.  @coolraygaming  remember that newton lived around 300 years ago

  10.  @100percentSNAFU  it depends. If atmosphere can compensate and redistribute heat, then it's ok. On the other hand, atmosphere itself can't actually be easily fixed with tech, if it's toxic or there's none, the planet can't be colonized

  11.  @AlexArthur94  project starshot is close to useless while being extremely expensive

  12.  @alexturnbackthearmy1907  light doesn't have a mass. Only momentum and energy

  13.  @PhoenyxuzPrimax  ok, so? That's just numbers. The only one who needs touch grass and learn how to make arguments is you, lol
