Cosmic strings and magnetic flux tubes as basic building bricks of TGD Universe

B. (Monopole) cosmic strings, cosmology, and cosmological constant

1. Cosmic strings dominate in very early cosmology during which space-time with 4-D M^4 projection had not emerged.

2. During TGD counterpart of inflationary phase their 2-D M^4 projection starts to thicken and becomes 4-D: ordinary Einsteinian space-time emerges.
3. Their dark energy consisting of Kahler magnetic energy and volume energy decreases and transforms to ordinary matter: this corresponds to the decay of inflaton field. The thickening of flux tubes slows down by the increase of the volume energy competing with the decrease of magnetic energy and one obtains radiation dominated phase.
4. These first accelerating and then slowing down periods of thickening repeat being associated with the decrease of length scale dependent cosmological constant by a factor, which is negative power of 2. The rapid expansion of Earth’s radius by factor 2 in Cambrian explosion is example of this kind of rapid jerk. This jerkwise cosmic expansion replaces smooth expansion.

C. (Monopole) osmic strings, flux tubes and physics and biology

1. All branches of physics starting from the formation of galaxies, stars, and planets down to biology, molecular physics, atomic physics, nuclear physics, hadron physics,… involve monopole flux tubes as basic entities. Ironically the intuition of string model builders was right but they were too hasty to ask how to obtain 4-D space-time and lost 35 years. The best manner to be really slow is to be very hasty.

2. Monopole flux which is direct reflection of surface property of space-time means a very essential deviation from Maxwell’s theory. These magnetic fields require no current as source so that that they can exists in very early cosmology where there are no coherent currents in long scales.
3. This explains the observed magnetic fields in cosmic scales.
4. Also the maintenance problem of magnetic field of Earth finds solution. Monopole part requires no current which requires energy feed to avoid dissipation. The ordinary part decays but the change of the orientations of the monopole part – magnetic body of Earth- generates currents regenerating the ordinary part. One can visualize Earth’s magnetic body as a magnetic animal turning its body to regenerate ordinary magneic field! van Allen belts would be associated with monopole part of MB and also auroras.
5. Also the recently discovered magnetic field of Mars with same strength as Eart’s magnetic field would consists of monopole flux tubes. This also explains Martian auroras.
6. The reconnections of monopole flux tubes give rise to topological dynamics associated with the formation of auroras. When otherwise unseen monopole flux tubes carrying dark matter as h_eff=n×h₀ phases reconnect part of dark matter transforms to ordinary matter and also currents (Birkeland currents) giving rise to ordinary magnetic fields are generated. This topological dynamics is behind biochemistry and biocatalysis. Molecules find each other by U-shaped flux tube tentacles which reconnected to pair of flux tubes. Then the pair shortens by reducing h_eff. This liberates energy making possible for reactants to jump over the potential wall making the reaction very slow.
