About the starting point, temporally, spatially,

If there is a four-dimensional theory to support, I can, but not now, the starting point According to the theory of infinite time in the universe, any time is the beginning and the end, and the infinite universe includes an infinite starting point, and there is no first beginning and no final end, because time arises in an infinite period, and in this period, only when you can enter the five-dimensional world, the energy axis, can you calculate the beginning of energy, the source of time.

In terms of time, China is at the historical starting point of another five years of "building a moderately prosperous society in an all-round way". .In terms of space, the new international competition pattern provides us with a new starting point.

But as the problem became more and more known, the real "question of time" arose in the 60s of the last century. At the time, physicists were struggling to combine these two theoretical frameworks, each of which successfully described the universe in its scope of application: one on a very small scale and the other on a large scale.

The quest for an all-encompassing "theory of everything" (a set of rules governing matter at all scales) begins. One of the most well-known, but also controversial, hypotheses was proposed by two physicists in New Jersey: John Wheeler of Princeton University and Bryce DeWitt of IAS. Wheeler and DeWitt tried to describe the universe in terms of quantum mechanics—that is, they applied theories that apply to small-scale matter to large-scale planets, galaxies, and other cosmic structures.

Many people have questioned whether Wheeler's approach is viable. Marco Genovese, a quantum physicist at the Italian National Metrology Institute (Istituto Nazionale di Ricerca Metrologica, Inrim) in Turin, Italy, said there was no indication that quantum laws could extend to the universe. However, it is at least logical to try to combine the mathematical formulations of the two theories and see what the results are.

When they combined Einstein's relativistic equations with the theory of quantum mechanics, they were stunned. Both sets of laws independently treat time as a variable that characterizes an event, but when combined, the time factor is completely canceled out in the mathematical equation. The two sets of equations resulted in a new set of equations describing the behavior of the universe, but at this point there was no longer any quantity in its mathematical formulation that could mark change or the passage of time.

"The Rough Spring Huwheeler-DeWitt equation shows that the universe is static and nothing is evolving," Genoves said. However, of course, we can all feel the time and change. ”
