Newton suggested that gravity can be felt by us. Why did Einstein say it didn't exist?

Hundreds of years ago, Newton was inspired by the apple tree and put forward an important viewpoint of gravity, which laid the foundation of physics. As one of the three classical theories of mechanics, the appearance of gravity also provides theoretical support for people to explore the operation law of cosmic celestial bodies.

In fact, Newton did not elaborate on the cause of gravity in depth, which also left a great space for future generations to explore. Some people think that gravity produces weight; There are also views that gravity has weight.

Einstein also made an in-depth study of gravity, and his view was more inclined to the latter, even thinking that gravity probably did not exist. This sounds incredible. People once tried to use "ether" as a gravitational medium, but later research proved that "ether" did not exist in the universe.

So dark matter is the medium of gravity, but it is still an unsolved mystery in the whole academic circle. Scientists have been trying to explore the existence of dark matter.

With the help of establishing a brand-new concept of time and space, Einstein believed that time and space are important reasons for gravity, and objects with different masses have different effects on space. This is similar to collapse, but it is a collapse in four or even higher dimensions. Objects with smaller mass can be attracted by objects with larger mass, and actually the former enters the collapse zone of the latter.

Relatively speaking, this view is more intuitive. Since gravity is the result of mass, it is easier to explain that the operation between celestial bodies, including the relationship between black holes and other special celestial bodies, is also affected by gravity.

At the same time, gravity has also had an important impact on related research, because the existence of gravity proves that everything in the universe has quality and has an impact on time and space. On this basis, if human beings try to travel through time and space, they seem to have new ideas and theoretical knowledge.

Scientists believe that if other dimensions really exist, we need to explore whether gravity can act on them. Because according to relevant theories, as long as there is mass, gravity will exist, or it may exist in higher dimensions.

At present, the academic research on gravity is still going on, and even near neutron stars, relevant evidence that gravity affects time and space has been found. With the deepening of exploration, people will have a more comprehensive understanding of gravity and its role in the universe in the future, and we will wait and see.
