the discovery of exoplanets many light years away means: we shall take good care of our blue planet and share it peacefully and instead of putting all efforts into destroying each other and all life on this planet – we need to become a multi planetary species – just as Elon Musk says – starting off with Mars and going further from there.
It will require enormous efforts and i always wonder why SpaceX is so lonely when it comes to funding such efforts – because this is in the end what hinders mankind to become multi planetary – the funding.
? at best: nobody is living there – at worst they interpret “Justin Biber” and “Shakira” songs as a threat – and launch a preventive strike with their singularity nuke against us (basically installing a black hole near our planet – destroying the whole solar system).
(this is a bit funny… but it is actually one REAL REASON GIVEN why US-military needs faster, better, more nukes with super secure launch codes like 00000000) that could kill all life on earth, before anyone reaches any exoplanets or even Mars ?)
Luyten b is a Super-Earth of around 3 times the mass of Earth and receives only 6% more starlight than Earth, making it one of the best candidates for habitability. In October 2017 and 2018, the nonprofit organization METI (Messaging Extraterrestrial Intelligence) sent a message containing dozens of short musical compositions and a scientific “tutorial” towards the planet in hopes of contacting any potential extraterrestrial civilizations.
