In another 20 years, can we achieve interstellar travel?

In another 20 years, we will be able to achieve interstellar travel.

In fact, this problem can be realized now. If you want to travel around the world, you need a plane to take it. With the progress of science and technology and the development of the times, more and more countries can launch satellites into the sky. For example, the successful launch of China Shenzhou series shows us that it is not impossible to go into space. From the beginning, there were only flying machines to now, many people can take flying machines together. It can be seen that this mode of travel will become the trend of future development.

More and more rich people will take part in trips organized by the state for this experience. This trip may be more and more like a flying experience. He will become more and more universal and convenient. People will have the desire to explore new things, and so will the rich. When they have enough money, they can buy anything they want with money. Things on the earth can't satisfy them, and they can't seek more happiness, so they can only turn their goal to never going to space. If businessmen see this huge business opportunity, they will invest a lot of money in the research and development of spacecraft, and there will be people who will fight for the benefits. A large number of scientists may be motivated by money, participate in various research and development activities, and then facilitate space travel.

Second, with the development of society, people become more and more. The environmental resources that destroyed the earth in 2000 were almost plundered. So resources are getting less and less, and people can get less and less. Although they have a lot of money, they can't sell what they want, and people will look into space. Maybe the future development trend of the earth people is. Explore other planets and build houses.
