Can detect another universe?

Although we can answer all the questions related to ourselves as well as the Earth or the universe, there is still a great question awaiting humanity. It is our outer universe whether there is any other universe?

Continue with the progress of scientists in decoding 8 most difficult issues of human science history.

Can pass the speed of light?

If aliens really exist, in the current situation contacting them is also facing many difficulties. Not the best is the speed problem. In recent years, scientists are constantly trying to achieve a superhuman speed, transcending the speed of light (faster-than-light (FTL). Compared to FTL, the speed of the spacecraft is too high. slow.

Since the beginning of the twentieth century, human reasoning has been controlled by the speed limit of light. But even if we achieve this speed, we want to reach the constellation Alpha Centauri, the closest constellation that takes us 10 years. That is not to mention the energy limits of spacecraft. Therefore, one thing is certain to overcome the speed of light to be able to carry out these journeys.

Recently, researchers have done a lot of related experiments. For example, an experiment by Lijun Wang, of Princeton University, was conducted in 2000 and a German researcher made in 2007 obtained certain progress.

Initially, scientists believed that no material or information could overcome the speed of light, but the pulse of light could do it. In a vacuum, light pulses can reach incredible speeds in different locations. However, this speed is still not helpful for our cosmic journeys. Experiments in 2007 are still controversial.

Gerald Cleaver, Baylor University professor of physics, said that in the "quantum entanglement" phenomenon, the rate of information transmission seems to be faster than the speed of light. In two experiments conducted in 2007 and 2008, the speed of 'quantum entanglement' exceeded the speed of light 10 thousand times.

Future FTL experiments can be carried out in multi-dimensional space, but until now we have not been able to fully explain these phenomena. Marc Millis, who is in charge of NASA's Physical Advancement Program, is working to study interstellar travel. He said: 'Certainly there are still areas of physics that we have not yet discovered.' Marc also said that dark matter and dark energy could be a positive direction in the future.

Can people travel through time?

Passing the speed limit of light has yet to be realized, of course, time travel is unimaginable. Einstein told us that the flow of time is relative. The farther away you are from large objects (like the Earth), the faster time passes. Although the errors are very small, they do exist. Therefore, satellites in orbit need to correct the clock according to this error.

In addition, this effect can also be detected at different heights. Two experiments by the US National Technical and Standards Agency have proved this argument. Therefore, our brain will age faster than the heart, even in the life of every human being, the age of the brain is only " older " the age of the heart by about 1/90 billion seconds.

Scientists found that the closer an object reaches the speed of light, the slower it will slow down. Therefore, a time machine can be simplified into a huge centrifuge. This machine can help a person reach the speed of light. However, Jeff Tollaksen, a professor of physics, chaired by Chapman University's Quantum Research Center, said that this method could cause people in this giant centrifuge to be cut into 4-5 pieces. Paul Davies, of the University of Arizona, said: " There will be a day when humans will make great strides ."

Can detect another universe?

Although we can answer all the questions related to ourselves as well as the Earth or the universe, there is still a great question awaiting humanity. It is our outer universe whether there is any other universe?

There are scientists based on the characteristics of the laws of physics giving the theory of the cosmic universe. The theory of such a pluralistic universe is the inevitable result of the development of quantum mechanics. Scientists believe that other pillars may leave certain traces before our universe forms.

Roger Penrose, of Oxford University and Vahe Gurzadyan of Yerevan Institute of Physics, discovered concentric circles in cosmic microwave background radiation. These concentric circles may be evidence of repeated explosions or rebirths of the universe. However, the temperature in the center of this circle is lower than the average temperature.

Although many research groups have also demonstrated this structure, the Penrose group's conclusions about concentric circles generated by the regenerative universe are still controversial.

In the past 10 years, there have been some scientists who learned through cosmic microwave background radiation to detect similar evidence. Therefore, they argue, there may be outer universes that have collided with our universe and left those ' scars '.
