A space-time formed by several espacios-tiempos?

A couple of days ago asked the community of Traveller in time about what topic to discuss on the blog, I received some suggestions and in the end I decided to contribute curious news about a discovery related to space-time which is in line with some of them.

A rainbow composed by different versions of space-time

Some scientists have come to the conclusion that in the models of the universe that use some of the quantum theories of gravity there must also exist a kind of "rainbow", composed of different versions of the space-time. The mechanism predicts that instead of a single space-time Normally, particles of different energies essentially experience slightly modified versions of it.

We have all probably seen the experiment: when light passes through a prism it splits to form a rainbow. This is because white light is actually a mixture of photons of different energies, and the greater the energy of the photon, the more it is deflected by the prism. Thus, we could say that the rainbow appears because photons of different energies experience the same prism as if it had slightly different properties.

Years ago that is suspecting that the particles of different energies in quantum models of the universe are essentially espacios-Tiempos with slightly different structures. The previous hypotheses, however, were not derived from quantum theories, but were based only on assumptions. Now, a group of physicists from the Faculty of Physics at the University of Warsaw in Poland, led by Professor Jerzy Lewandowski, has concluded that the space-time certainly it is formed by several different espacios-tiempos, and has even formulated a possible general mechanism that could be responsible for the appearance of such a rainbow of espacios-Tiempos.

The truth is that the theory gives a major shift to physics and the way of conceiving the space-time as a range with various values ​​and metrics rather than as absolute.

Science advances so fast that when you think you have an own vision and reach to understand that concern with space-timeWow! It turns out to be a metric and not a dimension. I have to confess that despite having raised a multitude of theories in our community, I still have no idea about anything!

Googling I found a free quantum physics course Through Tutellus, which I take advantage of to share with you, it should be said that I have saved it in bookmarks waiting for there to be a reasonable period of “dead time” in my life that would allow me to do it. We all know the “I don't have time” hypothesis that pressures, overwhelms and even frustrates us on a daily basis.

I leave a quote that caught my attention

«The total number of people who understand relativistic time, even after eighty years since the advent of special relativity, is still much smaller than the number of people who believe in horoscopes.»
