The potentially habitable super-Earth, officially called HD 85512 b, is estimated to be only 3.6 times more massive than Earth, and its parent star is located about 35 light-years away, making it relatively nearby. HD 85512 b was found to orbit at the edge of its star's habitable zone, which is a narrow region in which the distance is just right that liquid water could exist given the right conditions
Forget cost, political will and all the other variables — simply obtaining enough energy will take until 2196, according to Marc Millis, former head of NASA's Breakthrough Propulsion Physics Project and founder of the Tau Zero Foundation, which supports interstellar travel research.
Millis did plenty of extrapolating to reach this conclusion, which he presented at an astronomy meeting in Prague last fall and posted to the physics archive this week. He crunched 27 years of data on energy trends, mission energy requirements, individual energy use and even societal priorities, and chose two possible trips: An aimless interstellar colony ship, and a 75-year-long mission to Alpha Centauri.
Millis examined the energy required to launch the space shuttle during the past 30 years, which is a fraction of the nation’s total available energy. He assumes the same ratio will hold for interstellar flight, as Technology Review’s arXiv blog explains.
For a 500-person ship on a one-way journey, Millis figures you would need at least an exajoule — that’s 1018 joules — which is just a little bit less than all the energy consumed by the entire world in one year. For an unmanned ship destined for Alpha Centauri, you would actually need more energy, because you’d want to slow it down upon arrival at our nearest neighboring star. This would require 1019 joules. Even without accounting for fuel, the 500-passenger ship wouldn’t be able to launch until around 2200 at the earliest, and the A. Centauri probe won’t be ready until around 2500.
Millis’ math is actually more optimistic than other studies, which have suggested you would need 100 times the world’s total energy output to cover that distance.
I think God created the speed of light to keep us earth people from reaching other inhabitable planets considering what we have done to "the earth. Americas infrastructure is crumbling in every State. In American some people what to spend billions of dollars to see what is out there.
I suggest since they humans came from the stars and are part of those atoms, wait till you die you will return to the stars and see everything.
