  1. One of our biggest obstacles are ethics and morality.
    A soldier is sent to defend territories knowing that atleast 1 person is going to die in his platoon. He is willing to die. "For the good of his country" inotherwords for money.

    But, hipocracy as it is. We are not willing to send astronauts to die 1 out of ten times?
    When the ratio of atronauts deaths is equal to deaths of soldiers then space programs and technology will advance to the state we actually want them to be.

  2. I'm going to disagree that it has to be government that takes the lead because the private sector has more incentive to do it better than the government does as if we look at Space X or Elon Musk he wants to make so the average citizen can go into space so taking that into account so if it's not save for people and the space craft blows up during take off or if the space craft can't handle re-entry then it wouldn't be vary profitable for Space X. What needs to happen is investors need to be willing to take a chance on something that may or may not pay them back, but that's how you do business also there are people who are building space crafts in their backyards so to speak without asking the government for permission

  3. Can I ask a random question or through out a wild idea with no science background, if the theory is that the lightyear is the block and light time is the travelling time of light, which is lasers, which are molucales produced, could we not create not a shell but a flesh for those atoms, on the principle that humans are atoms with flesh as an organ? Super random thought

  4. If you took a space voyage that lasted only a thousand years (a very short time for space travel currently), by the time they got to anyplace to colonize, the culture that sent them would be long gone and perhaps completely forgotten. Also, many generations would be born and die during that long trip. We currently can not protect astronauts from cosmic rays. The crew would die long before developing any resistance to or protection from, those highly charged particles.

    Even without that, we have no idea of the many, many effects that long trip in a big box, will have on the humans inside it. They might not be able to handle even half of earth's gravity.

    Unless we can come up with a warp drive or some way of traveling faster than light, we will never send a person on an interstellar journey.

  5. I don't understand if we had the tech and ability to land on the moon in the 60s, how is it impossible to hit the next closest planet 50 years and tons of science and tech later.
    — It's like saying science and tech hasn't changed in 50 years. And if someone said that, they'd be laughed out of the room.

  6. I feel like people get the 'live forever' thing wrong. This means you can't die from old age or normal natural causes. But if you walk outside without paying attention and get hit by a truck, you're still gonna die. If you're floating through space for 50,000 years and on year 49,999 your ship hits an asteroid, you're gonna die.
