Can we live on Alpha Centauri?
So before even diving into the specifics of the system or its planets, no, humans can not yet go to Alpha Centauri and live there because, simply put, we wouldn't survive the trip. The Alpha Centauri system actually has three stars.
Will humans travel to Alpha Centauri?
To get there in anywhere close to a human lifetime, spacecraft will need to travel a substantial fraction of light-speed—10% would get a craft to Alpha Centauri in 44 years. Achieving such phenomenal speeds would require equally eye-watering amounts of energy, even for a relatively lightweight probe.
Which planet can human live on?
Kepler-62e and Kepler-62f are thought capable of hosting life. The planet Kepler-69c is located about 2,700 light-years from Earth in the constellation Cygnus. This is an illustration of the planet, which is the smallest yet found to orbit in the habitable zone of a sun-like star.

Is universe finite or infinite?
The observable universe is finite in that it hasn't existed forever. It extends 46 billion light years in every direction from us. (While our universe is 13.8 billion years old, the observable universe reaches further since the universe is expanding).
Is there a place in space with nothing?
The Boötes void (\ bō-ˈō-tēz) (colloquially referred to as the Great Nothing) is an approximately spherical region of space found in the vicinity of the constellation Boötes, containing very few galaxies, hence its name. It is enormous, with a radius of 62 megaparsecs.
