How has the knowledge and perception of the universe changed over the past century?

From over a 100 years the universe we knew and the knowledge that scientist possessed from the research of over thousand years reached to new peaks of development.

Explanation:

The researchers and scientist at that time had a broad mind about the development of technology and science, and they invented various electronic chips and machines which led to evolution in the universe.

Telescopes: Telescopes were made and developed to become more powerful and complex as they carried out research work in the different zones on the universe, specially in our solar system.Like Huble telescope which is on different missions to explore the universe and beyond.

Even there are some fields of research work in which the life and events happened in the past are explore and studied by the scientists and students.

It was a time when the government had the authority to produce and develop machines to explore our solar system, which led to many hardships for independent researchers and scientists. Now a days companies like spaceX, conducts the space exploration missions and collects important data about the solar system. Along with analyzing other heavenly bodies present in the universe.

The software were enhanced as new embedded system were introduced to execute various functions and research work. Along with that the super machines which covered the area which was equal to a room got so small and minute that people now keep there computers in pockets i.e smartphones.

Starting from the laws of motions and gravity, to the recent exploration of earth, moon, and moreover other planets, what made us more of human that before we do reasoning on imposing sanctions on not to let some one explore the universe, let them have the support from our side to enhance the technology and science overall. There were a number of research works which were carried out in the century or more.

i do agree with robert moses’ statements about wiping out cities that are an “impediment to new growth”. in order to have a positive community, the city must continue to grow either in terms of size or economics. therefore wiping out cities that restrict growth benefits the overall society and all the people living in it. similar to a social contract, i believe that if a person was to live in a community they must sacrifice some of their rights, in this case property, for the overall good of the people. as long as these people living in the cities are reimbursed and the purpose of wiping out the cities is to serve the public, there is no problem with robert moses’ core idea.
