For more than 6000 years, technologies that have been acquired by mankind for their well being has grown rapidly and exponentially compared through the overall lifespan of homo sapiens and the life on the planet earth as we know it. Todays human civilization on planet earth has grown to a level of concerns, overpopulation and overconsumption has grown to be a serious threat to the balance of nature of the planet and for the humanity itself. Researches of the level of earth sustainability have been organized and found that population growth and resources sustainability has almost reach critical level.

Eventually the earth will not sustain that much population, yet this is so far is opinion for none of the premised has been occurred or tested. Thus human civilization need to have another earth like planetary body to sustain their quality of living and basic rights of being human without much pressure from the wars, clashes of ideology, and competition for survival between others. Climate change, severe weather storm, drought, etc. has made planet earth is least comfortable to be ideally living in, and the population control program is also deemed to ignore the human rights to have family they aspire. Up until nowadays there are no other habitable planet in the solar system other than earth, G type main sequence star with the luminance similar to our sun sol is deemed to be necessary in the search of the habitable planet beyond the solar system. Hubble space telescope, and soon be operational James Webb Infrared Space Telescope not only have helped humanity to detect habitable planets beyond the solar system, but also help to safeguard mankind from outer space threats. The 1982 IRAS search for the undetectable object both the smallest and largest which could be threaten the human life on the earth has been successfully conducted. Other things like misuse of the advance cloud-base-lower-dimensional Artificial Intelligence (AI) is also condemned as a serious threat for human living on earth for their manipulative and degrading capabilities. Avoiding clashes between unknown extraterrestrial or multidimensional being is also a necessary for continuation of human living and to at least create redundant human species colony on the other solar system. Thus seeing these many possible threats has bought to hypothesis that the discovery of interstellar travel technology for human is deemed to be necessary to be accelerated and to be applied as soon as possible.
