Why can't humans ever reach another planet?

According to the American Fun Science website, the burden on Mother Earth is getting heavier and heavier. Therefore, human beings have been trying to find new habitats. However, Michel Majoor, winner of the 20 19 Nobel Prize in Physics, said that any idea of colonizing distant alien planets is wishful thinking of human beings, and human beings will never thrive on another alien planet.

He told AFP: "If we are talking about exoplanets, it is clear: we will not immigrate there. Therefore, it is necessary for us to get rid of all these ideas,' If we can't live on the earth, we can move to another habitable planet'.

He added that all known exoplanets (planets outside the solar system) are too far away from us and there is no practical way to get there. Mayor is a professor at the University of Geneva, Switzerland. He shared half of this year's Nobel Prize in physics with Didier Queiroz, a professor at Geneva University and a professor at Cambridge University, because he discovered the first extrasolar planet. The other half was awarded to James peebles of Princeton University for his new discoveries in physical cosmology.

1995 5438+00 In June, they discovered a natural gas giant planet similar to Jupiter at the Provence Observatory in southern France and named it "Pegasus 5 1b". Since Mayor discovered Pegasus 5 1b, his research has focused on finding planets outside our solar system.

So far, astronomers have discovered more than 4000 exoplanets in the Milky Way, but obviously, none of them can reach it. Stephen Kane, a professor of planetary astrophysics at the University of California, Riverside, agrees with the mayor. Kane said: "The sad reality is that at this moment in human history, all the stars are actually infinitely far away from us. As a species, we have made great efforts to land on the moon. "

He said: "We expect to send humans to Mars in the next 50 years. It may take centuries to send humans into Jupiter's orbit. Proxima centauri Centauri is the nearest star outside the solar system, 4.2 light years away from the Earth, which is tens of thousands of times the distance between the Earth and Jupiter, so almost all stars can't reach it. If we want to reach planets outside the solar system, we need to fundamentally change our understanding of the relationship between mass, acceleration and energy. "

Andrew Flach Noe, emeritus professor of astronomy at piedmont College in California, agrees that humans will not be able to reach these stars in the short term, but he also says, "I will never say that we will never reach these exoplanets and possible habitable planets".
