Does anyone know if there really is another space?

Scientists are devoted to the study of our universe. Is there any other space?

According to the February 1 1 daily report of Daily Science, people have always seen three-dimensional space, but people always think that there is another space in our universe, that is, four-dimensional space. Austrian scientists demonstrated the traditional three-dimensional space and the new four-dimensional space with quantum mechanics.

Scientists in Vienna are trying to understand the secret of holographic principle: our universe is a multidimensional space. Scientists have been studying in this field for a long time and put forward some great ideas. Quantum gravity is called the "holy grail" in modern science, and there is no unified theory so far.

Daniel Grumiller of the Institute of Theoretical Physics of Vienna University of Technology in Austria can now at least explain some mysteries of quantum gravity. His explanation of black holes and gravitational waves is quite convincing. Recently, he won an award for this, and he is going to use these funds to recruit some younger physicists in Vienna to do related research.

We all think that the space around us is a three-dimensional space. According to Einstein's theory, time and space are interrelated. Adding the time axis to the three-dimensional space becomes a four-dimensional space with continuous time and space. For decades, scientists have been speculating about this extra space hidden in our consciousness. Gmiller and his colleagues assume the opposite situation: if there is no extra space, then our space can actually be described as less than four dimensions.

Gemmiller explained: "You can see a hologram on a banknote or credit card. It looks like a three-dimensional image, but in fact it is only two-dimensional." In this case, the fact is smaller than our expected spatial dimension. Holographic principle plays an important role in space-time physics. If one doesn't always want to create a theory of gravity, he can build a new quantum theory in less space. In this way, the three-dimensional gravity theory becomes a two-dimensional quantum theory, and gravity does not exist. And this theory can correctly predict phenomena such as black holes or gravitational waves.

Gemmiller has been thinking: the question is how much space there is in our world. We haven't found enough evidence to answer this question. Perhaps the process of exploring this problem will be more meaningful. Gemmiller is currently studying the theory of gravity in two-dimensional space and one-dimensional space. They can be drawn into two-dimensional gravity maps. This theory can be used to describe fast-rotating black holes or space-time defects "cosmic strings". He and his colleagues from Vienna University will hold an international seminar from April 6 to April 24. Celebrities from Harvard, Princeton, MIT and other universities will be invited to participate. It shows that the gravity seminar held in Vienna is highly valued by the international community.
