Nobel Prize winners bluntly said that human beings have no chance to migrate to the stars. How credible is it?

201August 10- 12, the World Science and Technology Innovation Forum with the theme of "* * * Enjoy global wisdom and lead the future technology" will be held in Beijing Convention Center, including more than 20 Nobel Prize winners such as Gibston, Thomas J. Sargent and Zhu Xiwen, as well as many top domestic and foreign academicians such as Cao and Chen Gang.

On the evening of August 10, David Gross, winner of the 2004 Nobel Prize in Physics, gave a keynote speech at the theme dialogue 1: Life and the Universe.

Professor David Gross mentioned the famous "Fermi Paradox" in his speech: the Nobel Prize winner and physicist Fermi suddenly said, "Where are they?" This is the famous Fermi paradox.

According to Fermi's estimation, there should be many galaxies suitable for life in our galaxy, so where are these alien creatures? David Gross said that any star we can observe today basically has its own planet. We don't know the origin of life at present, but once the conditions are right, it should produce life.

When talking about how to spread life into the universe, what conditions are needed and how human beings will develop in the future, Professor David Gross said that this is a problem that we need to think about. He believes that human beings will spread life in the universe. He believes that the universe may be full of life, and although human beings may be only the middle part of its evolution, there is no doubt that human beings will become an indispensable part of the long river of life.

With the expansion of the universe, some people worry that the universe will gradually cool down and make life lose its energy source. Can humans survive in a cool universe? Professor David Gross said that recently, astronomers discovered that the universe is expanding at an accelerated pace. What caused the accelerated expansion of the universe? None of these questions can be answered at present, and scientists need to make continuous efforts.

It is understood that Professor David Gross and his students won the 2004 Nobel Prize in Physics for discovering the process of quarks' asymptotic freedom in the quantum field.
