From a scientific point of view, can human beings be reborn as time travel?
First, to know how to be reborn, we must first understand the world we live in. According to Einstein's general theory of relativity, the space-time we live in is four-dimensional, including xyz three coordinate dimensions and another time axis.
Xyz stands for length, width and height in space.
Then, the length, width, height and latitude of the three coordinates are bidirectional, and they can move forward or backward.
Why is only time one-way?
Is it possible to turn back time?
Second, in 20 19, Russian scientists did an experiment of time reversal. Several "undetermined" qubits in a quantum computer are "emitted", and these particles scatter in all directions under a certain program.
Then, by adjusting some parameters, these scattered particles return to their original positions, and the success rate of the experiment reaches 85%. That is to say, on the quantum scale, time is reversed, and time is reversed by a billionth of a second.
When Einstein put forward the theory of relativity, he proved the slow effect of scale contraction by formula, that is to say, time is not absolute. If you travel faster than the speed of light, you can go back in time.
197 1 year, American scientists Havler and Keating made a related experiment according to the theory of relativity. Two scientists used several cesium atomic clocks, four of which were put on the plane and one was left on the ground as the standard clock. Then they let the plane fly around the equator, once to the west and once to the east, each time for about three days. Finally, they looked at the atomic clock on the plane and the atoms on the ground.
International value: once flying eastward, the time on the plane is about 59 nanoseconds slower than that on the ground; When flying west, the time on the plane is about 273 nanoseconds faster than that on the ground.
Similarly, GPS navigation also proves this point.
There is an atomic clock in GPS navigation satellite. As the satellite flies around the earth every day, the time of the atomic clock is 7 microseconds slower every day.
Fourth, see here, let's give an example.
Suppose there is a constant temperature refrigerator and a two-dimensional creature in a speeding train. They live on the refrigerator door.
Because the train has been running at high speed, in their senses, the world is three-dimensional, but only the width and height can move back and forth, but the length is one-way.
At this time, a scientist had a whim. He instantly heated the handle of the refrigerator to a million degrees, and used it to expand with heat and contract with cold. At the microscopic level, he successfully reversed the length by one millimeter.
Then, they calculated that even if all the energy in the refrigerator is used, it is impossible to heat the whole refrigerator door to 1 million degrees.
Similarly, according to calculation, even if we use up all the energy in the universe, we can't exceed the speed of light.
So, from the macro point of view of the present universe, can time be reversed?
Back to the two-dimensional world just now, it is not the temperature that pushes the length forward, but the direction of the train.
Similarly, what drives the one-way passage of time in our four-dimensional space?
Speaking of which, have you thought of anything?
Let's talk about a science fiction novel.
The name of the novel is collapse.
Liu Zhu.
6. One day in the future, physicist Yi Ding will be invited to the observation hall of the National Astronomical Observatory, where people will pass through the radio telescope. Witness the transformation of the universe from expansion to collapse.
At this time, the once-in-a-century Yangtze River flood was flooding, and the governor took time out of his busy schedule and came to the observation hall.
But rockett's abnormal performance puzzled everyone.
He smoked carelessly, throwing ash to the ground at will. An understated comment, the photographer who just died of his father, even suggested that the governor remove the soldiers and civilians on the Yangtze River levee for flood control.
Everyone is puzzled by rockett's performance. The photographer even suppressed his anger and shed tears.
However, at this moment, the universe began to collapse. The galaxy on the radio telescope changed from red shift to blue shift.
Time began to reverse.
Seven, if the expansion of the universe leads to the one-way passage of time. Now, what is your understanding of time?
Can it be understood as the distance that matter advances on the time axis with the expansion of the universe?
From the moment of BIGBANG, the universe began to expand, and the earth, the sun, the Milky Way and the whole time and space, with the involvement of the expanding universe, continued to expand.
So, will the universe collapse like Liu's story?
Eight, the Nobel Prize winner in physics, British scientist Penrose. This problem has been solved recently.
Penrose's main achievement is to prove the singularity theorem in black holes with Hawking.
This year, Penrose is 89 years old, but he has not stopped his scientific research. In these two days, he published another paper.
The title of this paper is "Evident Evidence of Hawking Point in Microwave Radiation".
Penrose said that black holes emit Hawking radiation, which may spread from one universe to another, leading to a Hawking point.
At the crossroads of our current universe.
Simply put, it is to prove the correctness of the theory of cosmic circulation by proving the existence of Hawking point.
In his early years, Penrose always supported the idea that the universe existed before the Big Bang. He believes that the universe will continue to cycle back and forth between expansion and collapse.
If penrose's theory is correct.
Then, time began with the Big Bang and expanded into the future because of the expansion of time and space. When spacetime expands to a critical point, spacetime becomes a collapse.
When time goes backwards and returns to the time and space where we are now, human beings will be reborn.
Everything I experienced in my previous life is repeating.
In the time of countercurrent, human beings will go through the process from old age to childhood. People will wake up from death, go out to work after ten years of adapting to society, and return their life experiences and knowledge to the arms of their schools and parents when they are young.
The past will become a distant future, and today's future will be a solidified past.
Experiences from old age to childhood will also feel natural.
As long as the universe is not extinct, this cycle will continue.
Causal cycle.
The ancients saw the light of day long ago.
Finally share a brain hole.
In the collapsed universe, the busiest place is no longer a hospital, but a crematorium. At that time, every child would be crowded in front of the crematorium, waiting to adopt their parents, raise them to become young and die for themselves.
Therefore, please be kind to your parents in this life.
