Epoch of Inflato..(2)

Despite the seemingly unnatural descriptions that the IUTs give, they have a lot of backing from their ability to account for some of nature's phenomena. Such include:
Biasness of matter over antimatter during creation period- During the first few seconds of the universe both matter and antimatter were created. If they were exactly the same quantity, they would have annihilated each other resulting to an empty universe. Somehow, by a mechanism not well understood there was creation of matter over antimatter. In 1968, Andrei Sorhakov- the Russian Scientist who invented the Soviet Bomb- explained a number of conditions that would have ended up with excess of matter over antimatter.
1. Creation of baryons (the particles that make up quarks and protons) over antibaryons.
2. Bias creation of baryons over antibaryons. In a supporting experiment, J.H. Christenson found evidence that this procedure. The mechanism behind is however still not known.
3. According to laws of thermal equilibrium excess baryons would have disappeared in the process in what is called memory loss of the system. But since they did not, they must have been absence of thermal equilibrium to retain the excess baryons in the system.
The universe has up to 11 dimensions
Around us we see only 4 dimensions, 3 of space (length, width, height) and 1 of time. Recent observations reveal that our universe could be harboring up to 11 dimensions. As far back as 1919 Kaluza proposed the idea of a 5th dimension of the universe in order to create a unified geometric description of gravity and electromagnetism. Later in 1926, Klein proposed a 6th dimension for compatibility with quantum mechanics. Since the Kaluza-Klein model has been model has been extended to unify the other forces of nature.
1. Existence of parallel universes. Earlier on scientists thought that parallel universes could be existing. Now it's not just a speculation. While attempting to come up with a unified theory of quantum theory and general relativity scientists came upon the superstring theories. Now scientists know that our universe is just one of infinite membranous bubbles. Probably the next bubble is just a few millimeters away but we may never get there because space-time is curved. Scientists hypothesize that other "yous" would exist in infinite other universes. Maybe in one of the parallel universes, the doomsday comet that struck earth 65 million years ago just flew by sparing the gigantic animals. Maybe in another universe Einstein was too lazy to discover anything. Given an infinite number of universes there are all sorts of possibilities. Theory suggests that these universes could be contracting or expanding. And that these bubbles might touch. If the do, the collapse and form one universe. And that, as some physicists now propose is how our world came to being. Not by the Big Bang.

1. The smooth microwave background- Unlike in the BBT where the universe starts from about 10-34m in the IUTs it starts from about 10-12 of a proton. This allows for radiation and current forces of nature to mix and smoothen matter and energy. In the BBT, the fast expansion of the universe predicts uneven CMB radiation. The IUTs however allow for inhomogeneity to form later leading to development of galaxies.
