Past few days all around us we are bombed with the news about TRAPPIST-1. The cool red dwarf star what in her solar system contains even three planets what are compatible for humans to live on that is "only" 40 light years away.
Today scientists say that with the technology what we have now it would take "only" about 40 milion years to get there.
You can't say that dosent make you to ask yourself
ARE WE ALONE?
What is their story?
Are they itelligent?
and finaly
Why have aliens not visited us?
To get the answer to that question we first must assume they exitst, second, we must put our self in their position.
Our solar system has a yellow star that we call the "Sun" . We also know that in the universe exists many solar systems with more then one star.
So i also dont know even if they exist why whould they visit us. I mean, would you go on a 40 light years trip to visit a ★ start solar system? NO ! You would go find a nice ★ ★ ★ ★ or ★ ★ ★ ★ ★ star solar system.
