Is that really possible for us to travel to and live in another planet? I do appreciate the huge effort put by the tones of scientist who have been working so days and night to figure out the new possible place for human to live. But, I am really doubt the feasibility of this choice, which might also be our possible choice. Also, another well-known unknown, is there other lives on Mars? Is there aliens which might pose threaten on our life? Will they really welcome us to invade their home?We always think we already know most of the world. Indeed, we are so small and insufficient that there are some many unknowns out there.
2. Trappist-1 system
Highlights: a recently found solar system located 40 light years away that house 7 earth-size planets, …show more content…
40 lights years means it takes 40 earth years to arrive there travelling with speed of light(3.8X10^8 m/s)
How far is 40 light years? Let's us visualize it.
The below are some possible ways of travel to the Trappist-1 solar …show more content…
Also, as we learn in the cosmology chapter, the universe is keep expanding. By the time human invented such a powerful mode of transportation, Trappist-1 might already change its location, which will possibly more father away from us.
Although many scientists agree that the earth might still be habitable for another billion of years, so there is no need to find another planet. However, as mentioned in my previous blog, human population is keep growing rapidly and hence there might not be enough resources for human to sustain life for that billions of years. Also, as recorded in the earth history, there was a few times of mass extinction where most of the species on earth had been eliminated. Within the next 5 billion years, there might be also a couple of times of extinction ahead. The footprints left by us will be completely erased. No one knows there's one human
