Someone finally had to say it.
"When it comes to exoplanets, one thing should be clear: We will not go to them.". said Mayor in an interview with the French news agency AFP (Agence France Presse). Mayor thinks we should forget to find a replacement on Earth – in case this becomes hostile – outside the solar system.
According to Mayor, known exoplanets are far too far from Earth for us to reach. Even Stephen Kane, a professor of planetary sciences at the University of California at Riverside, agrees with him. getting to the moon is problematic, leaving the solar system is nothing to mention at all.
"Even in the case of a very optimistic scenario about an exoplanet not very far away, say, tens of light years away, it would take considerable time to implement it.", added Mayor. Unfortunately, humanity may need at least 50 years to fly to Mars (despite plans for earlier manned flights) and another several hundred to visit Jupiter's orbit. Considering this, think that the distance between Earth and the nearest non-solar star is 70,000 times bigger than the distance between Earth and Jupiter.
Of course, many things seemed out of reach before we finally reached for them, such as intercontinental flights. Nevertheless, "In this case, the physics needed to reach other stars, if any, are unknown to us and would require a fundamental change in our understanding of the relationship between mass, acceleration and energy."
Well, since we have no chance to colonize solar planets, at least for now, we should take care of our planet the best. For now, we don't have the second one.
We remind you that Michel Mayor shared half of this year's Nobel Prize with Didier Queloz. In October 1995 they discovered a gas giant reminiscent of Jupiter. The other half went to James Peebles from Princeteon University for his work in the field of dark matter and dark energy.
